Any time someone manages 200+ wheel hp on a Renesis I just have to applaud. You guys know how to get a rotary running right.
🙌🙌🙌
That might have been impressive 4 years ago lol
@Dee Jay with a ms intake, headers, a street port, and a tune 250 is more than possible na. Wasn't talking about na though, I know a guy who made almost 500 wheel with a turbo and nitrous. My car is at a shop now getting rx7 ceramic apex seals, a pin kit, and street ported. After that its time for a 2.1l pettit blower and maybe nitrous. Aiming for a hair under 400 wheel. More than possible if you're willing to spend the money
@@davesmith1698 landspeed rx8?
@@davesmith1698 would love to see this!
I think a lot of people (myself included) tend to forget that this is a 1.3L engine that’s extremely small in packaging! 200 NA wph given those two factors is pretty crazy...
Yes it's a lovely package. If you compare it to piston engine it's more like 2.6L, because each rotor fires every crank revolution. It should have been a 3 rotor from the factory...
Thts why i I love my dodge dart its the turbo 6 speed but for a 1.4 single cam few bolt ons an 93 pump and right at 200 also its fun asf
@@Domas64 it’s not comparable
@@riprotaries3145 Why not? It's a 4 stroke engine still. Just operates differently
@@Domas64 almost a 2 stroke nah no comparison lol
I owned a black RX-8 for 4 years and loved it. The car never let me down once. Drove it up to about 90k miles and then sold it. It was in amazing condition and still had excellent compression because I took care of the motor (frequent oil changes and pre-mixing). I wish I had never sold it. I've been trying to find a good condition RX-8 for the last 4 years with no luck. Every car I've found needs new apex seals (at the very least). Literally every one. I've probably driven 8 or 9 cars, and looked at far more than that. At this point it's better idea to buy a car with a blown motor and rebuild it if you're looking to get an RX-8.
I owned a JDM Type-S that died on me few years ago, had some fun with it but was dissapointing in many ways. Fast forward a few years later, I bought '99 FD3S and also circumstances happened I got the itch and got another RX-8 Type-S with 49,000 miles.. I just cannot justify this car, rose tinted glasses effect - Fun to drive but ultimately pointless. There are better daily cars and the FD3S is a better sports car. I 1000% regret getting it and now I can't even get rid of it even for a low price... Real sad... :(
I got lucky and found one with only 36k on it, for 7k
Actually found a 70k miles 06 6port for about 6k that I purchased.
Took me a better year of searching though
I just bought my first one last week...It's an 04 GT with 110k (runs&drives) and I got.it for $1,000 so I figured at that price and the fact they are only Gettysburg ng more rare by the day, I'd take a chance on it...My plan is to upgrade to a 3 rotor.I just can't decide if I wanna go with a turbo or Supercharger...I didn't have a buddy that races with an awesome machine shop, so we will be fabricating our own custom and lightweight components..I'm really excited to see the outcome....I have officially entered the Rotory fam 👊
@@onyren85 for the young of us who aspire for a FD but cant afford the upfront; the rx8 is the next best thing performance wise
I actually rarely see these cars on the road anymore.
It's sad :(
My son has one and probably 5 more in a half-hour radius
They are fun to drive, like they say around the 5000 rpm they take off and sound awesome.
@Polyglotgiorno90 exactly right. People dont know how to take care of rotarys.
You never see these in my town where i live, very rarely will you see 1. My buddy's 04 we just done a racing beat header, racing beat catback and simple intake, plus catch can and typical rotary stuff u should do. Such a fun car to take out and hit some curves. Joy to drive and the sound.. Gota love a rotary. Eventually a good tune will be done. Rotary's are lil different then my k serie's cars im use to tho lol nice vid👍
Hi! Tats great figures actually! Im from malaysia. My renesis na is running 215hp. 200nm torq after tuned on stock ecu. Before tuned was 196hp with 180nm. Currently mine is fastest rx8 in sepang f1 circuit. Clock at 2min 37sec. I love my rx8! Yes!
Thank you! Awesome!
Awesome video all around! Thank you. I really enjoy the rotary/8 content. I bought a 06 Shinka last year, had a baseline done (can't remember the CF) but only posted 140whp. MIL was on, and I've been replacing vacuum lines, sensors, going to be going back this summer.
Thank you Travis!
Almost 20k, well done boys, well deserved. Thank you guys for the content.
Thank you Jason!
To pull 200whp from a N/A is deff healthy! i wish i had a dyno by me just to see what im putting down. Deff want to see that part 2 of the mazda edit video. Im starting to get it figured out on my own but would love your input/tips. Trying to learn it inside and out before i put my greddy kit on. Sweet video man keep em coming!!
200 WHP and your mods are great for a reliable, NA, daily RX8.
Would modify my R3 similar to yours if I didn't have to worry about CA emissions.
Love the RX8/RX7 videos. Looking forward to your AP1 build.
And want to see a 2020 MKV Supra Slip Angle review!
Thank you Ryan! I'd like to drive the new Supra myself as well!
check out his other video on emissions, itll help for you since they just do obd testing on newer cars
Theres literally 2 to 3 smog guys willing to pass you if you grease their wheels in every california city.
@Polyglotgiorno90
Yeah I have a blue R3.
That probably wasn't me specifically but I've actually flashed my lights at a black R3 many years ago. We gave each other a thumbs up and drove away haha.
Great content. HEADER IS LIFE! I have an 07 gt with just about all there is. Act prolite flywheel and counter balance, ls2 coil swap, full exhaust with agency power dual res mid pipe and cat back, lightweight pulleys and the full package of mishimoto cooling items. Baseline figures were right at 180.8 whp. Chris at rotary performance in garland tx dyno tuned her using mazdaedit on a cool but rainy day. Mustang dyno but I'm unaware of any rate if correction. After several hours and nearly a dozen fourth gear pulls she put down 188.6 whp and 132.5 ftlbs. I went in with that sweet goal of a nice round 200 fully expecting to at least come closer. Engine is in great health with low miles. When speaking with chris about the results as soon as he started talking i knew where he was heading. Volumetric efficiency being our weak point. This being explained to me as a measure of air in vs out. My car was running at 90-95 percent while you would want this at 100-107 percent. The one part i didn't spend what i should of was the header. It was the first mod i acquired and was a "hook up" from a friend. It was clearly not the best put together thing but was much lighter than stock and looked better. Point being... With all the mods and care i have taken as an owner, i still couldn't come quite close enough to my power goal. Racing beat.. Here i come :)
188 whp on a mustang dyno is probably about the same as what my car made. Mustang dynos always read lower than DynoJets. What header do you have at the moment?
@@TheSlipAngle
A manzo i believe. Had to bang one of the tubes for clearance and grind one of my mounts to keep it from vibrating endlessly. While speaking with Chris at rotary performance he swore by the racing beat header, stating that it, paired with almost any set up is the overall best option. Almost 600 for a new one though 😬
@@eroc7667 I had the same problems fitting mine....just couldn't bare to cough up that huge amount for the racing beat header and figure mines still a big improvement over the standard iron lump.
Your power figures look good to me , over here in the UK the general opinion is the six porters make 170 to 180 max at the wheels stock.
I had mine street ported with the racing beat template and I have to say mated to a full system ( not expensive one) and a 200 cell cat it really pulls well post 5 k....I think for what it is it's a marvel and ok,maybe an s2000 might have it pipped but in tuned form you can hold one in a rolling run as I've found out.......and that is no mean feet for a 1.3 little drum of an engine
I also bought the cheap one but Port matched it to the exhaust holes because they were sloppy eventually I want to cut the collector off of it because everything but the collector looks the same as the racing beat but yeah I can't cough up that much for a header either
I’m going to do the same mods I think and see what happens on my R3. Minus the pulleys.
What a nice little run in Mexico. Very nice!!! 👌
;)
Drivetrain power loss is about 20%. With 238HP at the flywheel that puts you at 190WHP and you made about 10WHP more, so your flywheel HP should be right around 250HP
Hello Nate,
I too like you would quote a % for tranny loss; however be careful that's not very accurate. Take high hp cars 400-600+hp they don't loose 80-120hp through the drive train.
miata is always the answer
That ending tho... nice car brother. Cnt wait for the s2k man!
;)
The 231 stock power figure is not correct (yes I'm saying Mazda lied), a good stock 6 port usually makes about 215-220 at the crank.
It depends on what testing methods you use, and when you do it. If you remove the ancillary items and use an engine that has just bedded in, you can get around 181KW with the ECU firmware that Mazda never actually released. In a closed, controlled room, a fairly fresh engine gets about what mazda said, but it doesn't take long for the horses to leave the stable.
Antimation Studios I think this is true for a number of car manufacturers. For instance the highly publicized volkswagon, and then Hyundai. They just make numbers look good for a particular market. Let’s say gas mileage for sedans, bhp for sports cars etc.
My old tuner did a rb26 swap in his rx8. It was a wiring nightmare. It took for ever to complete and get it running right. By the time the car was done the owner was so over the whole thing that he sold it when it was finished and running.
It's one of those things people don't realize about these cars. They are actually remarkably well tuned stock. There is very little to drag out of it with out FI. Almost no gains through Bolt on mods, minimal through tuning. Largest ways to gain power are just cat delete headers and a tiny bit of tuning.
I've owned 3 of these, all of them were terrible, and I loved them dearly.
Will you be doing more tuning with mazdaedit soon?
mines just failed its mot on emissions, the garage was a bit puzzled, no engine lights were on so they checked the o2 sensors they were ok when they took the cat off they found there was nothing in it, it had disintigrated,so they put a new 1 on, I think it runs better with 1 on, is it just me or does it need other changes as well as just having no cat
Hi, what elaborations have you made to this machine?
I think the Renesis is pretty much maxed out at this point unless you boost it but then reliability will flush down the toilet.
I vote you enjoy it as is. That’s how Mazda designed it to be. Don’t ruin it.
Nice numbers overall for a 1.3L haha. I wish mine was as healthy as that. I’m probably in the 175s due to the low compression. ☹️
Yup, I agree. It's pretty good as it is now honestly. I think overall I am pretty happy with how this car is for a daily.
@@TheSlipAngle yep learned the hardway. It stores to much heat as it is at the exhaust ports and can lead to warpage or killing your seals sooner.
this is not a maxed out renesis on what grounds do you have to say this ? What have you done?
MSengineering David - maxed out as far as bolt-ons go.
Sure you can crack open the block and do a $15,000 N/A build but I don’t think that’s what he’s going for here.
There’s just nothing more he can bolt on to make more power at this point in the built.
Artem Brayson then do not open your mouth and say max out with a sub par tuning method... because that’s isn’t maxed out.
Nice vid and nice gain. My brother in law owns a rx8 and man it's not super fast on the straights but get it in the twisties and man it's fun and fast. I love my fd but that rx8 chasis stock for stock is better than my fd. Quinn I ran against a modded 02 vette z06 and pulled on him. Now a modded 08 z06 well that thing is badass. If I ever got tired of my fd an 08 z06 it will be. For the money that 08 z06 is great value for its performance. I am a sucker for 911 also. Damn so many great cars and not enough garage nor money. I want all three. Lol.
The RX-8 chassis and suspension is just on a whole other level. I still think the RX-8 has the best all mechanical suspension to ever leave the factory on a production car.
Anyone tried an Odula throttle body? They port it out and replace the butterfly for more gains, I am super keen for this!
200 is light ... 232bhp after rebuild and ethanol conversion for my r3
Wish I could daily mine bro. Those are some great numbers. I’ve found a person local who can do a 13b-rew swap and use rx8 face plate for rx8 accessories. If I turbo it’s gonna be rx7 motor b/c lower compression engine and it likes tuning more. But If I don’t turbo I’ll do what you did and just port the Renesis exhaust ports and bolt ons/ecu. Thanks for the videos Quin!
Anytime Lex! Thank you!
Have you Dyno'ed your RX-8? Let us know the numbers, mods, type of Dyno and correction factor!
The Slip Angle we made 177whp on our mustang Dyno with Carla’s RX8. Intake and exhaust with Mazdaedit.
Did you notice the stock parameters fighting the changes you were trying to input with Mazdaedit? It seems like this car was richer on the dyno than on the street, even with the ABS fuse pulled.
Funnest car you’ll ever drive!
Hey mate did you ever post a video on the mazda edit stuff you mentions will be in another vid?
Go for the Adaptronic eMod013 ECU, it's way easier to tune than MazdaEdit. Waiting to see your updated fuel and timing maps in the next episode :)
Is it a standalone or piggy back?
@@TheSlipAngle : standalone, fully pnp, you only need a wideband kit with it.
i see that you dont have a rx7 fc,,,what is your opinion about it?
Gr8t video!
At what rpms do each air valves open?
I don't remember each RPM off hand but you can see the dips on the graph where they are opening.
What with the smoke on decel? Either way good info on the modifications and Mazda Edit. I will be using VersatTuner which appears to have full control of the AFR's.
No cats + Premix
Mark any piggy-back type tuning is going to clash with the stock ECU parameters. This is why I just run standalone ECUs in everything. If passing emissions weren't really a concern anymore I'd just throw a Haltech in there and call it a day.
Anyone know what rims those are on the rx8
That's damn good for also being emissions compliant. Have you thought about the BHR long tube header for "some torque"? Thinking of going Haltech or Adaptronic standalone? Thoughts on E85 for the rotary? Stoked for the s2k build. Glad your 8 is at an exceptional level of health.
My own 8 won't be ready until I get back and I put it all together. Current plan is BHR long tube header, BHR resonator, HKS hi-power single exit exhaust, AEM intake and Adaptronic PnP modular ecu with E85 flex sensor for future potential use.
I looked at the BHR, but it's quite expensive for a mild steal header. I also wanted to be able to run the big RB resonators to keep the noise levels down. Eventually I am going to retire this car as a daily and put a 20b or something in it in which case I'd run a Haltech. Not a fan of E85, I like the convenience of 93 pump. On an NA application the e85 will allow you to run more ignition advance to make a few more hp, but I don't think that is good for longevity of the motor. I'd be interested to see your build as it unfolds though. Keep us updated brother!
I'll keep the updates coming and thanks for replying. I'm deploying in a week so project start is pushed until I get back. I'll have suspension, intake, engine, and steering wheel mods (thank you for the video btw) waiting for me. I'm a little skeptical of E85 as well, but the tuner I'm going to use is doing extensive r&d on it for the RX-8 specifically right now. I guess I'll have time to wait and see. Also while I'm away I get to math out how to shove 11" wide wheels into those awesome arches without flattening the pinch weld on the inside. Gotta squeeze 315's to keep up with the national prepped BMW's in DSP. Have a good week. 🤙
Mazda ECU will always try to overwrite. Your changes are seen as Baseline to ECU. You have to drive various speed and restart for 40+ miles for it to settle into the tune
Yeah it's a big annoyance
@@TheSlipAngle What's your favorite stand-alone for this platform?
Great video brother! Nice seeing a healthy Rx8 do it's thing and your tuning seems to be on point. As much tracking as you do, have you considered doing a compression test? Curious to see the how well the engine is holding up.
Thanks buddy. I've actually only put this car on track once for an episode of the Slip Angle. I haven't done a compression test, but it shows no signs of compression loss. Even with a warm engine, it fires right up with minimal cranking.
When will the final MazdaEdit tuning part 2 drop?
been waiting for this!!!!
me too!
I suppose rx-8 is not the most popular but I am still waiting for the part 2 on Mazda edit :D
I don't think there is going to be part 2 :P
Knew that shop looked familiar...
Maybe :)
Is this in a 4port or 6port renesis ?
6
Yeah I teat drove a 2003 z06 before I bought my s2k. That shit is too fast for me..I'd do something stupid in it
Always use tuners who have ample experience on rotaries specially renesis engines for rx8. The rx8 engine is very different to the rx7 and distribute heat differently.
Maybe a tuner who is familiar with Rotaries and understands their leading / trailing spark, but as far as the actual tuning, the process for tuning the Renesis is no different than an older 13b.
@@TheSlipAngle but it is different. Exhaust ports on both engines is so different that heat accumulates on one side of the engine. This is a physical limit to how much you can push performance. This was done with the focus of mpg to appeal to more mainstream consumers. The 13b rew hasnt this problem.
Yes, the RX-8 got rid of peripheral exhaust ports in favor of side exit. This creates more heat for the side seals. I've talked about this in previous videos and said that I don't think the Renesis is a good choice for a track day motor where there will be long periods of sustained high RPM. This is more a limitation of the engine design and not the ECU tuning.
Looks like ya got some less than perfect compression there lol
So is this the donor motor for na miata 😉
NA Miata needs a 13b with peripheral intake and exhaust ports for extra brap ;)
What kind of wheels are those? They look sick
Enkei Kojin
@@TheSlipAngle thank you. U absolutely love your vids. Very informative.
Anytime. Thank you!
Want to go fast! Go think aircraft technology! Then again, you can only get what your engine can muster in its frame base..
What are those wheels??
Enkei Kojin
How many miles on it?
43k
These cars are cheap right now. Time to buy before the price starts going up!
Josh C my brothers step son got one for 1500 but it’s already hurt.
Josh C it runs ok but it’ll need to be rebuilt sooner or later
You didnt do a street port right?
Nope, stock unopened motor.
@@TheSlipAngle well 195 whp without any porting is very imoressive, even if the motor has ~30k miles.Will you ever port the engine?
@4:40 yo is that an r3 ?
Mazdaspeed 3
It's a Shinka Edition
Would be interesting to see 100-200 kph or 60-120 mph times. I think it is most accurate way to compare. Mine did 19,5 sec 100-200kph(3rd and 4th gear) when it was fully stock with cat.
I'm going to do some VBOX runs with it soon.
What rims are those?
Enkei Kojin
Did you camber the car? I'm getting an RX8 myself and looking to do the same work you're doing to yours.
I'd like to know all of the mods you've done to your whip.
Good "bolt on mod" is an REW swap lol
LMAO :)
It’s a nice beautiful car especially the s2. They’re just under powered saddenly. Unless you swap to a rew 13 turbo
funny how the guys at 3:30 are having a conversation then the RX8 gets into high RPM and they stop lol, rotary power
Respekt brap lyfe lol
Got my SA22C ready for this summer! czcams.com/video/9wxpHdqcxYk/video.html
Brap brap
Hey Quinn, I'm not sure if you are aware of Chris Muscat's ITB 20B engine, which has a simple yet ingenious variable trumpet system that changes the length of the stacks through the rev range. The took inspiration from the 787B Le Mans winning 4 Rotor Mazda. Given what you have learnt on this car, and the RX-7 build you have going on, I think this system could be your next project in the pursuit of ultimate response. czcams.com/video/04uhsLqKwF8/video.html&
Oh, and here is an explanation from Engineering Explained of how it works using a similar system on the La Ferrari V12 : czcams.com/video/I_bOGqeHYlM/video.html
I saw this lol. Pretty cool, but a little more complicated of a setup that I would prefer to deal with.
Tai lu
I am just bias towards rew swaps. 470whp. 😝
lol
Buuuuullllll shit!!!!! The RX8 does not run a sub 15 at any elevation.
Like I have something to gain by lying about that? Better question does it really matter? Like 20 people actually care about these cars.

Slowwwwww 2 stroke blender
Has this engine had any port work done?
Unopened original motor.
The Slip Angle awesome! If you ever do a rebuild, or have one rebuilt, it would be great to see you do some porting etc and then see the difference in power etc
