The alternator should be investigated like this too. I'm sure its ancient design can be improved also. You do not hear of upgrading the alternator to make it more efficient.
Yeah, a more efficient alternator with an underdriven pulley could reduce a bit of parasitic drag. Either that or swap a few other bits and change the crank pulley to get it all at once
Renault has some "piloted" alternator, it works on demand.
If I remember correctly, Toyota and Honda has this type too.
Interesting! I wonder if there's a straight forward modification to change the pulley or belt with something more effective
@@tabryis this is achieved simply…. Kiss method boys instead of driving the alternator from the crank drive it from the drive shaft … doesn’t work for dayly drivers but it’s used in racing often
I had the pulley belt fail and had to drive home without the alternator. You could probably complete a one-lap time attack without the alternator at all! I wouldn't have believed this myself, but the car worked fine. The battery was brand new, though.
Seriously, every video (upload) gets better and better! I'm looking forward to the future of CARPRIME, Tsuchiya-san!
@Zani Taniri so youre saying youve never watched initial d?
I agree, superb
@@Cichlid_Visuals we must report every post like this. I dit it. 👍
They should have check the old and new fuse with multimeter to check the resistance, that might explain why.
Enjoyable video with some very down to earth guys! And regarding the fuse power increase claims, they did state more than once that the power gains from the Magic Fuses were due to the original fuses likely not being in very good condition. I love that decades later, DK and Max are still just as enthusiastic about cars, tuning and driving as when they were younger.
Tsuchiya San keeps the 3.5 gear ratio. You can see clearly how he changes gear from 3th to 5th ( In real he changes from 3th to 3.5) and then he change to 4th.
Can you explain that more for me pleaseee
Ps. Sorry for the english
@@ym40ubeto66 DK replaced his 5th gear with a gear shorter than 4th but longer than 3rd so "3.5"
Developed specifically for a better gear ratio at Gunsai Touge.
So going through the gears he goes 1-2-3-3.5-4 which means shifting from 3rd to where 5th would be and then "downshifting" to 4th when in reality he's still upshifting.
Very odd but very smart
yes 3.5 gear
I didnt expect fuses to make that much of difference but it makes sense that resistance grows as contacts get oxidized over time and that effects function of electronics. Kinda reminds me how my father used to upgrade battery cables (ground and to alternator) and make ignition leads by hand from components because "they were better than store bought".
Very easy modification and really helps with starting the car in adverse weather conditions.
This car must feel really fast onboard, and against a chrono even in straight line. With around 220 bhp and 930 kg, wow, that is like my car with 312 bhp. That is 4.23 kg/bhp an exceptionally good value
I think people react so much on this because of a combination of factors.
Dyno runs for instance, these days most of us watch Garage 4age, nick's garage, motortrend, sloppy mechanics or MCM's dyno sessions (or all 5).
So we know at least a little bit about oil quality, fuel quality, intake temperatures, fuel temperature (yes, it's a thing), water temperatures, oil temperatures, air humidity, engine load, consistency and the like (and some of us know the lot).
I don't know what happened behind the scenes, but let's be honest, this video was pretty subpar when it goes for the inconsistent dyno-testing.
Then there's the negative naysayers, with them I bet the alarms went off weeks ago thanks to the GT86 and AE86 videos that went on and on about these fuses.
And then there's omitting fuse testing.
I hope Carprime realizes by now that they skipped on a simple multimeter test of the new "miracle" fuses vs new OEM fuses.
I hope Carprime does a resistance test between OEM and Miracle fuses, starting with unpacking every item out from their respective factory seals and measure them for resistance.
All it takes is a multimeter, the items in question, and 2 minutes of your time, in one uncut unedited segment with everything on a table shown clearly without interruption (seriously, uncut, unedited, uninterrupted, no taking the camera away or you will stand immediately accused of hiding swaps by people in the comments).
That should rectify any damage and shut everyone up 😁
My personal opinion?
I'm 100% sure everything is on the level, when DK said he felt the difference, I believe him 😁
I've taken a lot of these AE86 harnesses apart over the years, and have found them corroded several feet in from their respective connectors, what does this do to engine sensor > ECU voltage, not to mention alternator load, pray tell?
Been fiddling with nickel-type wires and custom harness here and there on AE86's myself, results has me wanting canbus for everything under the dash.
I can easily see these fuses, if made with a nickel alloy of some sort (or something and/or the other), easily reducing alternator load, in some cases more than others, and have engine performing better than even brand new OEM fuses, it's especially noticeable on pickup and response, exactly as shown here.
Finally.
To the people who say you cant feel a few % decrease in power, sure, when you've got enough to spare you don't notice as much, at 10% loss you probably just crank the wastegate a little bit or blip a computer or w/e.
But you haven't owned an AA63/AE86 GT/AE82 GT FX16/AE101-111 Caldina-Levin-Trueno (or combination of either, 20v in AE86, 16/20v in KE70, TA40/60 etc), at least not the way they "should be owned" (yes that's a thing) > Everything can be improved :D
You haven't truly known powerloss the way we do.
Changing final drive to 4.7, tearing out A/C and replacing P/S with manual steering rack in the name of reducing engine load? Easy! 🤣
To us, every 0.01hp matters, 0.01% power loss? I WANT THE INTRUDER BROUGHT BEFORE ME IN SHACKLES 😂
A couple of fuses? Hold my beer 🤣🤣🤣
Fuses are such a little thing, it sounds impossible, until you feel the car is down on power, you've tried bore-scope, injector cleaning/testing, swapping harnesses (that are now 38>34 years old, they all definitely have corrosion damage at least to an extent), sensors, full engine rebuild, and everything else and in between, so you try fuses, and boom, it works.
Agreed with all your points, I would highly suggest people at least try to replace their old fuses with new OEM fuses and see if they can see an increase in power before dishing out $500 for these miracle fuses.
I really hope a channel out there (Garage 4AGE) tests these fuses out, I will gladly eat my words if after extensive testing these fuses show consistently that they add power, hell I'll buy and throw them in my AW11 for that sweet 10% power increase.
@@16bmidniterfoxo Yeah even just at 1% its worthwhile, and better for fuseboxes with less heat accumulation (I've had and have seen burned fuseboxes due to fuse resistance).
new fuse can definitely increase power because of better connectivity, but i assume just 2-3 hp, 7 hp is impressive. I wanna buy that also
Looks like just a difference in oil temps. With hotter oil will gain power as engine revs, just like it does here. But if someone sends me some of those fancy fuses, i'll test them
@@Garage4age Absolutely!
Oil temp alone easily accounts for the shown difference in power, and that's before we talk about intake temps, fuel temps, fuel quality... the lot of it.
As I already mentioned before (in case anyone gets the wrong idea) the dyno segment is subpar compared to what we've become accustomed with on your channel and channels like yours, it's as simple as that.
Whether or not those "magic" fuses actually contribute to measured power-gains = I defer to you in a heartbeat.
Been around with the blasted Corolla wiring enough that improved feel (rather than measured results) in response/pickup makes me pretty curious about the fuses.
Not curious enough to splurge on them at current asking prices though 🤣
They cost about as much as fresh pistons, and the engine in my guinea pig is coming in at 38 years old since it's components were last laid bare for the naked eye, compression is less than minimum OEM spec, so an overhaul (which is what I'm aiming for) will serve me far better.
Fuses will have to wait 👍
I "defend" (not that they warrant any sort of defense from me, but you get what I'm saying 😂) the fuses in so far that I've swapped out more than one corroded wire and felt better pickup/response, it just doesn't take much when you deal with wiring this old and drive the car every day for 10 years.
When DK says he feels a difference while driving, I have no reason to doubt that😁
man I FREAKING LOVE this new channel. Its criminally underrated, hopefully you guys blow up !!
I won't believe it until Garage 4age tests it
Fuses are BS, weight reduction on the battery is a nice improvement.
agreed
@@16bmidniterfoxo resistance builds up over time, resistance robs electrical flow which removes power. its perceivable to say that replacing shotty fuses reduces electrical resistance and restores power, you dont add power you just get back whats lost over time
@@andrewkaminskas7721 Agreed, new oem fuses are a more sensible solution rather then $500 magical fuses.
Looks like difference in oil temps the way it gains with revs. but hey if someone sends me overpriced fuses i'll test them.
I love this pair of car enthousiast showing us their way of life on a " normal buddy day" modding car with love.
It's also very curious to see such a difference by these mods.
Mister Orido, Tsuchiya, please come to France and spent few times set-up my S2k and why not, few French cars too.

Deal !
that 7A-G sure do sound beautiful, I can hear the main engine sound along with its resonance tone and it sounds super pleasing 8:37
The only other test I would've liked to have seen would be testing brand new normal fuses against the Magical Fuses, too. That would be in addition to how the fuses were tested in this video.
Feeling the changes is the nicest thing, please make more relaxing video like this
Definitely super interesting considering the wide variety of engine bay variables per car. Thank you!
DK, Maxu and Nobu never gets old. Great trio
This is amazing. Great job Mr Orido. I hope his business flourishes.
A million thanks for the english subtitles!! Ae86 for ever! I could watch DK and Max driving around and chatting for hours haha
Temperature of the engine bay will also affect the battery’s output
also the power output
The battery was new out of the box, and was probably down on charge. They should have checked the voltage before installing it.
Incredible gonna have to look into this for my s14 and z33. Thank you guys!
Tell me if you found it for z33
Worthy upgrade 👍
thank you for the English subtitles!
Tsuchiya is literally so precious. His expressions, his mannerisms, the way he speaks, it's all just so humble and sweet. Despite his age, he still has such a youthful spirit and still drives so impeccably well. A true gift to this earth, and a very treasured one.
Best auto channel ever. With these dynamic duo how you cant be entertained and gain knowledge. With cheeky and silly tsuchiya san and technical orido san, this the best ever!
Love to see all this videos, I used to watch the videos from hot version but now this is better it just not racing it's also mechanics topics and part of life of this amazing driver Keiichi Tsuchiya, I've learned a lot since years ago from him, gettings from Colombia
Super ultimate miracle fuse 😄
I must have these super ultimate miracle fuses.... shut up and take my money!
I love listening to these guys. Grew up in high school watching the BMI videos....sigh nostalgia.
His love for his 86 is like my love for my old '90 galant, i bought me a brand new behicle but somehow i find myself going back to drive my old little guy with all his miles, so much fun.
I hear you brother, I feel the same way about my 2K Maxima. I still have my Hyper ground kit and a hyper voltage setup after all these years, I can say it makes a little difference in torque and power. I am keeping the Maxima in the years ahead but I am getting a electric mini cooper se for my daily.
I love learning details about Tauchiyas super bean and watching it progress. Thank you Drift King and Orido San for sharing!
BEST CHANNEL EVER
Merci beaucoup !!!
Big salut from France 🇫🇷
ViNZ.
Wow I didn't expect such a difference by just changing the fuses. Also 8kg less must feel great in such a light car.
Especially since the battery sits so far forward. Makes the difference even bigger
@@nsaal5400 It overhangs the wheelbase and sits high up too, so this should reduce the pendulum effect, as the mass is more centered this way. Also why its beneficial to move a battery inboard for a track vehicle, less resistance to rotating, less mass hanging outside of where it's easier to control.
Great job
Very Good Content👍🏻 Anyway, I love about JDM❤️
Nice Patek Mr.Tsuchiya
i like the feeling about making the Super Mame DKsan wow from the result everytime. Worth-it reaction. Money well spent and time for the result. Sugoineh 💯👌🏼👏🏼🙌🏼🐐

Tsuchyia san is the GOAT. Will always enjoy your work.
thx for video, it was shocking and nice for me
Imagine how much power would be made from removing the electrical system completely.
That watch though! We see you DK!
I was nervous for Orido lol. Happy they made power for the Super Bean.
Legend with legendary car
Mr. Tsuchiya i think you need to upgrade the grounding cable for your engine. I believe it can up the horse power too.
I've had my 86 changed the same SHORAI battery and magical fuse around 4 or 5 years ago, much earlier than Mr. Orido san started his shop. I was surprised and wondered why there's only a few people know that by changing these two items can make such changes at that time because I really felt the difference even if I didn't have a chance to make a dyno test on my car. And now they came out with these dyno videos, showing people that it is acutally giving your car a little bit more hp (quite a big improvement for NA cars) and better responses after the small upgrades, anyway I gotta say it's definitly worth it and I'm happy to see not only Mr. Orido san approves that, and even Mr. Tsuchiya san does too. Great videos :)
What fuse is being replaced for this?
Not really worth it for $500 fuses
@@Rockit181 Magical fuse with the same rating. You won't gain much on a new car with shining new fuses. Got better chance with 30 years old AE86 though,
Battery would make a big one it’s placement is bad for the cars moment of emerita and overhanging the wheelbase it cantilevers weight so you’d really feel the pounds shaved even if u just re located stock battery somewhere nice and centre in the car and low
But what does happen recharging a 21a battery with a 80a alternator
thank you for including english subs!!!!

I'm glad that everybody i the end feel satisfied... orido is relief, the magic fuse owner too and Tsuchiya was happy too. I'm now curious to see the super mame on the circuits! Thumbs up , continue with these videos!
I can't believe I just found this channel!!!!!
Thx for finding us :)
plz share on SNS and to your friends.
For those curious of how this made such significant power, its simple. A fresh battery requires less from the alternator, and a fresh fuse decreases resistance and voltage drop, which in turn causes the alternator to have less parasitic drain on the engine, allowing it to put more of its power to the wheels. In reality, Tsuchiya san's 7-ag is easily a 240 crank horsepower engine.
I'm not buying that. Let's assume that the car is equipped with 80 A alternator (it's just my guess, but in a ballpark of what I would expect in a car from that era). Under full load, it can produce around 1 kW of electricity. With some loses that's about 1,5 HP. But they didn't change the load at all. State of charge for both batteries is debatable, but both were used for starting before test run.
Also the Ohm's law tells you, that if the circuit has higher resistence, the current will drop, together with the power drawn. So if the fuse caused the voltage drop, it actually made the alternator work less (unless the car is equipped with modern brushless fuel pump, but I don't think so).
@@TrinomCZ There are dozens of possible variables here, and alot of assumptions in your response. My point is to offer a simple explanation as to why we dont need to treat a very nice video from Tsuchiya and Orido like a federal case in which we scrutinize the technical possibilities of 8 horsepower.
the reality of this video is not making horsepower, its restoring horsepower through reduction of parasitic losses, both kinetic and electrical in nature.
@@TrinomCZ it way more than 1.5hp you forget the drag in the alternator caused by the magnet and the alternator is overdrive so it take more hp to turn it
It not a 1:1 ratio the alternator pulley is as less 2 time smaller than the crank pulley
Some things in the car are directly voltage related like the fuel pump. More voltage means more fuel. I did a complete rewire of my fuel pump with high grade 10gauge cable (stock is something like 18-20 gauge) and a new relay and measured a significant voltage increase which meant that I was getting more fuel pressure to the engine (which better atomizes the fuel coming out of the injector). This is a very simple, low buck modification, and I would recommend it to anyone.
OEMs unfortunately do not wire everything properly. You can do the same thing to the car headlights and they will be significantly brighter as well.
That engine is a wet dream😍😍
I likes how Max shamelessly promote Maaya in the end there... lol
a que chulada de carro precioso el ae86 del maestro tsuchiya saludos desde mexico
impressive.
Nice nice and thx have the English word description.
will have to get some fuses then! their faces! thats true surprise right there
I respect Dk & Orido, but I am very skeptical this makes any difference once you account for unavoidable variations between dyno runs
Its less than 10% which made it neglegible but I saw orido video and it does made a little bit of power. Also when running on dyno the more runs you got the hotter then engine will get and less power it'll read and since on his video he installs the battery and fuse last yea it did make a tiny more hp.
My guess is, maybe the fuel pump or some other device wasn't getting enough juice originally due to the old battery or some point of resistance in the old fuse?
@@Grumpini this may be the case but replacing with any quality fuse will improve this instead of spending 100s of dollars on magical fuses.
Also, the lightweight lithium batteries have a slightly higher voltage, which *could* improve performance, as the ECU would be subject to less voltage variation from the alternator.
By far the biggest and most noticable performance improvement is the 6kg reduction in mass.
@@comando293 oh absolutely, i'm very interested in the battery for that purpose
That 3.5 gear is awesome
I have a lot respect for these 2 men but i also have a lot of questions after watching this video…
1. I can see how and why a lighter battery upfront makes a difference in handling. This I agree.
2. What if they replaced the old fuses with new normal ones? Maybe the old ones are just deteriorated hence the power difference?
3. Every time when we remove the battery, it resets the ECU. The feeling of the car being more responsive could be because of that
I’d agree with you on a newer car… these older cars are so “stupid”… the ECUs are VERY basic, even with a standalone ecu replacement I can’t see any reason unplugging the battery would have any affect… they don’t really have an emissions system, or OBD that needs time to relearn…
Thank you for the translations, always greatly appreciated!!

Now i want them for my FRS
To be fair, they should change the old fuse to the new stock fuse then use this amazing fuse..
And the fact most people forget, professional racing driver is testing the products and with they driving experience simply no need to make it fake... They are telling the truth about "before and after"!
I believe that Tsuchiya & Orido are honest people - but I'm sure magical fuse sounds like snake oil to anyone who understands basic electrical theories. Here are just a few observations:
I doubt very much that changing the small blade fuses would have a measurable impact on the engine output, and it's important to note that there are much bigger 60-120AMP (or more) fuses used for things like headlights which are NOT replaced or included with magical fuse kits.
Secondly, many of these smaller fuses (which are the ones being replaced) are tied to systems like the radio, wipers etc. meaning even if resistance is decreased (using better conductors/connections etc) it would not show in the Dyno tests, as they are likely switched off.
Increasing voltage or amperage (as some comments mention) would have 0 effect on the speed of the ECU, as these are computer controlled (tied to CPU clockspeed and other factors) and not reliant on voltage or amperage. The only situation where this would occur, is if you have a bad/old battery where the voltage is below design tolerance (
100%, Most of these fuses would be carrying on and off signals... increasing and decreasing voltage for an on/off switch is functionally pointless, the only explanation I can get from the gain would be if the old fuses were degraded and not working properly. Brand new oem fuses would perform just as well imo, these snake oil salesmen fuses are a way to rob gullible fanboys of the channel.
I love Tsuchiya but damn it sucks to see this type of stuff on here...
At least Orido's battery has a functional purpose to reduce weight on a track setup.
I agree. This is just marketing for snake oil.
All the ECU driven actuators, such as injectors and coils, are powered from battery/fuse, power does not come from ECU. The benefit from more stable power circuit, there should be less O2 correction if you have correct injector deadtimes, injector size and VE-table. Especially if Super Beans Motec firmware does not have transient enrichments, this would explain some of why the engine feels more responsive.
For the peak power, there should be oil temp shown on the video. You can see from Garage 4A-GE video how 20deg C difference in oil temp affects peak power number on highly tuned 4AGE.
@@drpdrp5690 Fair point about the ECU not driving the actuators, but I don't see how a fuse would affect power stability (it's not like it's switching a circuit, it's a solid connection). The lithium battery may have a positive effect on the power stability as it is a completely different technology/chemistry to lead acid. But as that is a much more complicated question which goes well beyond my understanding, so I purposely chose not to comment on it.
I think the only valid point made in the video (in regards to magical fuse) is about heat degrading a fuse and increasing it's resistance (which as TC said above, the sensible solution would be to replace with a new OEM fuse). In fact if they really wanted to show the effectiveness, they would compare magical fuse to a new oem fuse to prove that it is worth the high asking price.
To be clear I am no electrical engineering expert (I just studied the basics), and it would be awesome if an Electrical Engineer could properly analyse and respond to the claims made.
By that measure, replace all the copper with pure silver and minimize length to annihilate the voltage drops on the system. I don't think anyone does that...
Good result for this type of upgrade. Power losses in second run are higher by 4 hp + you always have the tolerances of the dynos. Nevertheless a good result and the weight reduction at this height at the front will be observable during racing sessions :) But very costy..
Yeah over 600 USD in fuses.

Wow, thiis car revs to the sky!. Max power at 9000 rpm, cut off at almost 9400!
25$-30$ a fuse? That’s just insane!
these people learned it from Pif*er...
Small volume hi spec stuff.. Theres nit enough economy of scale i would think. Like how a 3090 vs 3080 minor improvement but huge cost addition
Wonder if the crew driving the STI at 14:54 knew Orido-san and Tsuchiya-san were passing them at the toll. Orido-san even comments about the Subaru.
factory fuses are already high quality, usually made by MTA, Bussmann, Littelfuse etc. they dont use dollar store multipacks. i suspect if it is oxidation then removing and reinserting the fuse a few times will scrape some oxidation off. they really should have done a multimeter test.
Right. I am skeptical. Show us the resistance values in ohms vs a regular commercial fuse. Perhaps the truth may come out....
@@EnjoyCar again cant argue with dyno results too. maybe it has a similar effect as upgrading ground cables. old cars usually have poor ground wire gauges.
👍👍👍👍👍
@CarPrime ^^ 🚫 block this spam ^^
neat
So essentially those mods improve the Voltage Level to the electronics right?
More Voltage to the coilpacks, fuel pump, injectors and ECU must increase HP.
No that's not not how it works
@@RBGgermanKX250F so tell us how it works then
@sr20drft well extra voltage to things like, ECU, coil packs, fuel pumps won't increase power because feeding them more electrical energy does not make them put out more power (as long as there isn't an underlying issue already).
Your injectors will not spray more or better fuel if you give them more voltage. There is a compensation in the ECU to keep fuel amt sprayed vs voltage equal. This will usually be called something along the lines of Injector dead time table. So Increasing voltage will not change the amount of fuel sprayed.
Additional voltage to fuel pump may make it run harder but if it was already providing enough fuel then there will be no change because the fuel pressure regulator will still regulate the pressure the rail and injectors see down to the same pressure. Thus same differential pressure across injectors and thus same fueling. (Not that extra fuel automatically makes more power. Small changes usually make no difference. Going too rich or lean will then.hurt power. But there's a pretty broad band of air/fuel mixture where an engine will operate close or at peak)
More voltage to the ECU will just get regulated to it's working voltage. So nothing changes there..more voltage also wouldn't make it work faster or anything like that.
Extra voltage to the coils won't help unless there is insufficient voltage to begin with. In most cases as long as spark is sufficient a larger spark won't make more power.
There is a possible theory that if the resistance in these installed parts is less that there is then less strain and parasitic drag caused by the alternator which would free up some horsepower. However this is also very...out there if it would work.
This testing is just nowhere near scientific enough to actually prove anything.
Too many variables not kept the same.
Hope this helps a bit. If anything further needs clearing up am happy to try 😊
@@RBGgermanKX250F i think they just didnt warm the car enough or it had bad fuses to give that much power. But i do have to say coming from an electronic's guy there is such thing as dirty power so fuse and a new battery could make a more consistant delivery which could make it somewhat more reliably deliver power. But all of that is kinda out there.
it could be lowering the pull from the alternator so it saps less power
Chip trick ... We open a hidden Oxygen tank in front of the engine second test - and engine gives more power. Lot of Dyno testing facilities do this in USA - to convince you -your car has now much more horse-power
I believe Tsuchiya if he tell from test drive that his car behaves better. Tsuchiya is an honest man and has no need to lie. I respect him, please do not look for this cheating practices on this channel. There are not any miserable thieves.

The SHORAI battery sounds like a good upgrade when the time old battery need to replace.
Which model of SHORAI battery best fits to AE86? Is the mounting kit available as well?
Just about make out battery model at 20:50 its LFX21A6-BS12 I believe
Can we have part numbers for the battery and fuses?
Just love how Tsuchiya is so unconvinced with the idea of fuses adding power that he often times went "Fuse de ne......"
Pas compris le fuse de ne
Well. The battery improvement might be not as expected as the battery was propably sitting for a while on a shelf and even if its new it might be a little bit "hungry" for power. So right after it was installed in a car the alternator was propably working even harder that with the old battery. The old battery was charged by the alternator just before the dyno run and the car was also driven to the shop, so it was definetelly charged up to the max.
Well I was thinking about moving the battery in my car to the trunk as A4 B5 layout is making a car very heavy at the front, but I realised that with my skills - i will not see any improvement anyway. :D
Absolutely agree with this. Most lithium batteries are stored at about 40-50% power. They should have checked the voltage before installing it. In this case, they might have actually bungled the entire back-to-back battery test.
As for battery relocation, you can definitely improve the balance of the vehicle. Unfortunately, the necessary cable adds a lot of weight. I moved my battery to the trunk, and it did improve the balance, but I also really enjoyed the fact that the battery was no longer running at engine bay temperatures, which helps improve battery life. Also, it's easier to install inverters, and run wires to aftermarket audio systems.
There's a lot of ancillary benefits to relocating the battery. Just make sure you route the cable properly so that it doesn't rub against the frame and cause an electrical fault. Also, make sure you put a 150amp fuse right next to the battery in back. You would much rather blow that fuse than see the shower of sparks a chafed battery cable can make! Trust me on this one!
I really wish there were more AE86s to go around. Especially those that are more stock rather than those with stripped interiors and engine swaps.
People are forgetting how to drive a fun car these days. Nothing wrong with a 130 HP stock output. It's a car for learning the basic fundamentals of driving as well. Simplify, then add lightness, the AE86 is the embodiment of that.
@@Joshua_N-A Yeah, right? It’s like with all the Supras and Skylines. They get rarer by the day and all everyone does with them is strip them and give ‘em 1000 horsepower.
In America, you almost never see the rear drive AE86. It's a very rare car, unfortunately. Finding a stock one is basically impossible.
altenator next
Ok that's amazing..were can I buy these fuse..👍👍👍👍👍
I know that bosh make the best break booster ever. It makes drum breaks feel like disc breaks
DK 86GT with HKS turbo soon? OMG
Next, R35 coils
Not convinced with that “Magic Fuse”
lol that suspicious face that tsuchiya put up when they hand him that bag of fuses.
May be 4 o 5 bhp are lost because with ITBs, the direct intake trumpets don't receive as much air in the dyno as in the open road or track? I don't know really, but maybe it is not the same in a car with a more normal intake sucking air from the front grille on the dyno with the typicall air fan
I noticed when Tsuchiya-San was shifting, he still has the "3.5" gear setup, where he shifts from third to fifth position, then down to fourth for a close ratio! Edit: is there a recommended model of the Shorai powersports battery for car usage?
I was wondering why he kept going from third to fifth. Glad somebody explained it, thanks.
Gotta love those open intake trumpets too!

Just about make out battery model at 20:50 its LFX21A6-BS12 I believe
@@cameronbell4097 good looking out! Wonder if it has enough cold cranking amps for a 2L engine in colder climates.
@@rhubarbpie2027 If you have worries, get the LFX36A3-BS12 it has 36Ah or reserve and 540CCA. Orido san is rocking a 315CCA battery for a 1600cc motor and said in the other video the startup power is amazing.
