@@kiesh. If you have a rim dimple and both dots, then prioritize the red dot and dimple. Get the shape right, and then balance the weight the regular way.
If in doubt ask.... how would I identify where the dimple is? Thanks for the red dot bit, never spoken to anyone who shared this important info before.
hay man Have you heard of/looked into electronically controlled valves, you can gain 30% more power, it would give better throttle response and give you complete control of the Engine performance throughout the rev range, of course you would have to redesign the top half of the engine. but if you make it out of billet aluminium you are gain strength and reduce weight anyways
Matt, those tyres will honestly make a night and day difference..... on the faster corners you'll be a gear higher..... I had r888s on my last mx5 track car, and that was my finding!
More cam lobe, a bit less separation angle, longer intake runner (throttle valve-injector-intake valve) a slight hone on the ports, big airbox with cold air channel and stronger spark. Just trying to adjust the trumpets will not give much of a gain, even with a different tune. To get the WHP over 200 mark, you need at least 500cc more displacement. That means bigger crank and pistons. But, tuning the head and intake will bring the number relatively close.
That is so interesting. I once had a conversation with an Australian motorsport identity and he stressed that horsepower comes from the cylinder head. It will be interesting to see the developments here.
My wife, who is the most uncar person in the world, loves the name of your car. We visited Thirsk and London in January, 2019 and loved our trip. Your channel is great to watch as I learn something in each episode. Thank you from the States.
Thank You Toyo for the upgrade, with the wider tires are you going to have any clearance issues? I like your "DRIVER FIRST" mentality and always "WORK WITH WHAT YOU GOT" . I guess I have fallen in Love with the MONGREL the way SHE IS and am afraid of change. Thank You for your continued posting of your work and talent, it is much appreciated.
Beautiful build, top notch fabrication and welding skills (honestly, some of THE best welds I've ever seen!) As for getting more power ... one word, TURBO(s)!
Typically shorter runners move the torque up the rev range so I expect less power up the top unless you can go to a setting shorter than you already have. Keep up the vids! Enjoying them!
I’m afraid changing the length of naturally aspirated ram pipes won’t really make much difference. Valve overlap and larger valves is usually the only remedy….
Watched the build right through mate, brilliant outcome, my first car here down under was a 100E prefect, 1956, always wanted to rod it but got married instead, now doing a couple of 39 fords, love the mongrel though.
Red dot lines up with the punched dimple when working on steelies (good luck finding that on a scabby wheel) . Yellow dot lines up with valve on alloys . Not all manufacturers provide dots though
Good stuff getting something from Toyo. Hope it leads to other things in the near future and tyres for the other cars too. Always enjoy watching your videos.
I'm with Demon Highwayman, look into cold air or Ram Air feed once you've sorted the trumpet length out! Love this build and still in awe of your fab and welding talents mate!!! I'm interested to see how else you're planning to add power to this. I'm hoping you might look at NA applications rather than bolting a turbo kit on as NA these engines are great so hoping to see a full build. Either way I'm sure it'll make great content! Cheers Matt! You legend!
Not sure you'll get much more power out of it with different length intake runners but you'll definitely effect the torque curve. I'd predict a smoother curve with more low end torque with a longer runner. Should be interesting though. I'd consider building an air box with a good cold air feed if you want to make more power..... won't sound as good though!
Stancy pants now. How about fabbing up a box over the trumpets and running a supercharger. Low boost obvs lol might just perk it up a bit. Be a good project to watch on your channel too. 😁😉 I can't remember off the top of my head now but I believe you left the engine pretty standard? Good Port and polish, camshaft and maybe some injectors should be a good start on the power side.
I'm quietly confident that all you will do with the trumpet length is change where the torque/power curve is as, if I remember correctly, you run a standard cam. A cold air feed would help nicely with cooler air flow. I'm not sure whether this is applicable to your car but some engines don't like sticky rubber as you can oil starve them.
Love your channel. Can't wait to see the results of that intake test, although it looks to me that your intake runners are already quite short. If you find that shortening them doesn't significantly move the power peak, it's going to be cams and/or or head flow that make the difference. There are plenty of tools online that will calculate ideal intake runner dimensions to determine what RPM they tune to.
Phil from driftworks used 3d printed trumpets to help find the right length for his desired performance , just incase you've a mate with a printer handy 😂😂👍
The yellow dot is the lightest point of the tyre and the valve is the heaviest point of the wheel. Thus lining them up, sort of helps with the balancing.
Matt, if you want to move peak power further up the Rev range, you should initially fit the next level camshaft as I’m guessing the one you’re using is a yellow road/rally cam. You need to go to the next level with a bit more overlap (between the exhaust valve closing and the inlet valve opening…) Piper R&D or Kent Cams should be able to sort you out buddy! 👍
You're right about driving low power vehicles improving your driving skills, I once had a vivaro which did 0-60 in 20 seconds and after 4 years it improved my smoothness and entry/exit speeds because you didn't have any acceleration! For the trumpets, look at variable trumpets- Porsche and Nissan used them and they work off vacuum. A good way to get more torque across the board.
Would chopping the trumpets and adding a sleeve not create turbulence ? You will have two steps in the inlet. If I were you I’d ask ATR to send you all the sizes they make and just give them some data back. GBS their sister company sell a mx5 based kit-car so I’m sure the data would be useful.
I'd be curious to see how complex it would be to incorporate variable throttle body intake length like on modern 4cyl superbikes. I dare-say a far bit of computerisiling would be involved. That stock cam profile is going to be the biggest/easiest hurdle to clear, relative to positive performance results. Cam first then fine tune your fuelling/in-take. Such a beast of a car, i bloody love it!
Love the mongrel Matt 👍🏼 what about a set of cams along with intake runners? Even a mild set should in theory give you more top end. I used a 268 degree in my golf, which like the mongrel is a low powered track car (130bhp ish) and suffered from top end power loss. it made a hell of a difference in the top of the revs and now pulls hard all the way to the red line. The R888 will also blow you away if the track is dry - fingers crossed. 👍🏼
Love some Mongrel content. The car turned out so great and I'm really enjoying that your keeping the project around and showing what it takes to optimize a project like this. Many youtube projects don't show this level of detail on the build and when the build is done the car just disappears. Keep up the good work. My only regret is that there is a ocean in between me and my chances of ever seeing this car in person.
I suspect the power is falling off due to the stock cams signing off there. You may get a couple hp from messing with the trumpets but I wouldn't expect much.
Aye Matt. The Yamaha R1 uses variable length tubes. I was working on one and found all does is, at full tilt the tubes get lifted off the throttle bodies and then seat back down at lower rpm. It could be the other way round when on the move but that's the position they were in when stopped.
And don't forget about your exhaust. Are you able to add collector length? A combination of carbs (getting air into), Camshafts (letting the engine breathe) and exhaust (using that to help breathing) should help your Dyno readings. Also, what gear are you running in the rearend. 3:50 or 3:55 ? Both gears are good for road tracks... Combined all will get you better lap times ! Been there. done that..
I’d try making a makeshift plenum, or several plenums. Lots of guys have had big wins with this on escorts etc as the air filters can sit too close to the end of trumpets and restrict airflow into the trumpet itself. Plenum volume can be tuned easily using basic materials like cardboard or plastic until you’ve found what will work on a permanent basis.
Long trumpets for torque, short for top end. To move up 1000rpm you'll need to take about 30mm. But runner length can do strange length and not only move your curve up and down the rev range but when you hit the sweet spot it'll add a whole new peak that wasn't there before
Nice up grade on the tires ... 100 HP upgrade, that would be awesome, but good to trouble shoot and fix adjust with what you have now, looking forward to your next reveal.
lining up the dots should help with the amount of weight needed to balance the wheels. and it is so easy. from my couple of weeks of trying to like the miata (i am 5'11 and can't see through the windshield), i think it needs torque more than anything. small turbo would fix that. 120 to the wheels should easily put you in the 120mph range if it has enough gear. give the mongrel some torque.
Thumbs up for TOYO . Be cool if they support you with future tyres/technical advice . They do seem proactive in supporting respectable youtubers .

Short velocity stacks are for quarter mile. Long velocity stacks are for more top end. Medium stacks are a balance and best oaf both worlds. It all depends on the track you are at. You also have to take into consideration your rear end gear ratio and how many gears you are running in the transmission. Again, it all comes down to the track you are running. Long straights are a way different beast than a twisty track.
Hey mate, Rick from Oz here. I'm a mechanic of over 35 years. Have you considered increasing your valve spring rate?? The longer the valve can stay closed the further you can hold RPM. Have a look at your cam spec sheets and make sure you meet its requirements. Could be losing alot of power through a mechanical issue.. Hope this helps... Enjoy watching your work.
I stopped watching a video about the ridiculous new Countach to watch this instead, your car is way more interesting and in my opinion a sweeter looking machine. Love your work.
On these tiremachines theres a hole on the front of the beadpopper , its there to drop youre tire iron intoo so you can get to it eazy To increase te power on the engine i think putting lower compression pistons in there and put a turbo on it would make it quite a bit more powerfull it allso would change the powerband though
i had a mk2 1.8 engine, all i did was skim the head 40 thou. on the dyno was 150 at the crank. longer runners with a cold air feed for the trumpets. followed by camshafts or atleast intake cam with a ported head and port matched. should make a difference! or... you go down the root of just putting a more capable engine in. mazda L engine are alot more tuneable. fully alloy block so lighter. they're cheap and parts are everywhere for them.
Stick like the proverbial to a blanket eh! Those rubbers will be marvelous. I put race rubber on my 750 a couple of years back and it transforms the grip when cold, once they warm to your ride they stick man. Like white on rice?
Matt - it needs a Jag S type V6, 240bhp out the bag and lighter than the MX5 lump. With your exemplary engineering skills you would only need the Rocketeer or other adaptor plate for the standard gearbox and the rest would be a doddle for you. Just wanna see the mongrel bark louder and bite the heads of M3s. Haha
Further research says the Pipercross filter should be OK to 220 bhp so I was wrong however the distance or trumpet end to inside of the filter still applies
Looking forward to seeing the dyno results. Emerald ECUs have an adjustable set up for just that idea. And years ago, a guy called Graham Bahr experimented with runner length on his BMW race car, e30 iirc, and it seemed it got better as they lengthened. I think they even had the trumpets out of the bay on the dyno! Pretty sure it was Dave Walkers dyno. Those Toyos are nice, i switched to them from Michelin PS3s on my GTI, and dad uses them rallying sometimes.
Those 888 toyos are the badgers nadgers!!!best tyres I’ve ever used,stop messing about and put small turbo on,up to 10psi at most,Ecu ready for it,😎
Toyo - Very generous of them. I shall put a set on my own MX-5.
A red dot is the high point and is to be matched to a dimple on the wheel. A yellow dot is the light spot and is to be matched with the heavy stem.
What if the dimple and valve don't both coincide with the tyre dots? Do you prioritise one over the other?
@@kiesh. If you have a rim dimple and both dots, then prioritize the red dot and dimple. Get the shape right, and then balance the weight the regular way.
@@jonasthemovie nice! Makes sense once it's explained, thanks for taking the time 👍

Quick tip for removing track rubber from bodywork, mr sheene!!! Spray on, leave for a few seconds, wipe off with no scrubbing. 👌🏻

I think Dave Walker at Emerald had a set of trumpets you could vary the lengths whilst mapping. Saved fiddling with swapping over.
I’m afraid changing the length of naturally aspirated ram pipes won’t really make much difference. Valve overlap and larger valves is usually the only remedy….
just so nice i didn't think anyone could make that car have so much appeal. took all my bias and gave it a proper stiff toss out the window.
Would a cold air feed directed at the trumpets or some bonnet ventilation to vent the hot air out help with the power ?
I'm sure it would.
This car grill and overall shape reminded me of of the old 100E Ford Prefect that my friends and I use to hoon around in in the mid 60’s.
Watched the build right through mate, brilliant outcome, my first car here down under was a 100E prefect, 1956, always wanted to rod it but got married instead, now doing a couple of 39 fords, love the mongrel though.

Two things to get the response you need are high compression pistons & cams to give you the powerband you’re looking for

Some sports bikes run uneven length trumpets inside the air box for a wider spread of power, two short and two long.
He should try that on dyno day👍🇬🇧

Short velocity stacks are for quarter mile. Long velocity stacks are for more top end. Medium stacks are a balance and best oaf both worlds. It all depends on the track you are at.

Long straights are a way different beast than a twisty track.
Can’t wait to see the result !!!
those wheels are perfect
👍👍think about ceramic coating the Mongrel 🤘
Hey mate, Rick from Oz here. I'm a mechanic of over 35 years. Have you considered increasing your valve spring rate?? The longer the valve can stay closed the further you can hold RPM. Have a look at your cam spec sheets and make sure you meet its requirements. Could be losing alot of power through a mechanical issue.. Hope this helps... Enjoy watching your work.
Hi Rick, cams are all stock at the moment mate. Cheers
Nice! Looks great. Camshafts :)
I stopped watching a video about the ridiculous new Countach to watch this instead, your car is way more interesting and in my opinion a sweeter looking machine. Love your work.

A good set of cams will move power up a fair bit. Turbo next, an easy 100hp
On these tiremachines theres a hole on the front of the beadpopper , its there to drop youre tire iron intoo so you can get to it eazy
To increase te power on the engine i think putting lower compression pistons in there and put a turbo on it would make it quite a bit more powerfull it allso would change the powerband though
i had a mk2 1.8 engine, all i did was skim the head 40 thou. on the dyno was 150 at the crank. longer runners with a cold air feed for the trumpets. followed by camshafts or atleast intake cam with a ported head and port matched. should make a difference!
or... you go down the root of just putting a more capable engine in. mazda L engine are alot more tuneable. fully alloy block so lighter. they're cheap and parts are everywhere for them.
whit couple of o-rings, lock screws and 2 different pipe size you can do adjustable trumpets.
Stick like the proverbial to a blanket eh! Those rubbers will be marvelous. I put race rubber on my 750 a couple of years back and it transforms the grip when cold, once they warm to your ride they stick man. Like white on rice?
Curving those intake runners up will be a plus if you decide to add a hood scoop. Also, the runners should increase in diameter toward the air filter.
Toyo are one of my go to tyres used them on my mk 1- 3 mx5s great in all conditions good luck Matt 👍👨🏻🏭
Cheers.
Love that car.
Looking good bud. Make sure you make some provisions to make the trumpets shorter as well as longer.
Will do, Cheers
Power is in air flow. Head work is the easiest power gains. Then camshafts.

You need an cold air intake? At high speed the air will be getting rammed into the engine.
Momentum cars are fun
