Miata Gets a Bigger Turbo & 32PSI!!! New Power Record - But Does It Lag? [Full Dyno Test]

I don’t care for small turbos And all this response non sense Go for the bigger housing and make the big power from the get go

[@LUCKIPUP]

@@JNAMOTORSPORTS power doesn’t matter when greg primarily wants a responsive turbod car, especially in a era where turbo technology is constantly getting better to the point where you dont need 70mm turbos to make north of 700

Boost OUT OF CONTROLLER:))) Such a CPC thing to say I could see you almost cried..after all this time in the driveway and that mouse hole of a garage..insane amount of time and effort you put into car, videos, and always left some energy to entertain. Tha car is sick, everything about it, and sounds sick, so yes, you can be proud. Cheers!

[@daleabono3616]

Super video. Thank you! I can just hear your engine talking at 32psi.... Oil: Hey, whats all this fuel swimming around down here? Rings: We're doing all we can, mate! Greg: Screwit! I'm slayin' mustangs!

[@nissan_s14_]

greg: aight jus 1 mo psi engine: aight i'll take it fuelpump: what you doin stepbro. i'm stuck

[@ryanroff6330]

The 7163 has surprisingly very similar response to 6758. It’s because for the 7163, the inlet turbine the compressor wheel has a hybrid design. It works so well it overcomes the size difference which would normally cause a decent bit of lag. That hybrid wheel solves that.

[@GTFour]

7163 is also a twin scroll design too

[@legocfl9282]

Just when I thought 400hp in a Miata was insane... crazy numbers man. Keep up the awesome work, I would be mostly lost with my NA without your videos!

[@dennisrobinson8008]

And can get to 500whp without much if any loss of lower speed torque.

[@kolopiom_og]

Keep it up kraigh, 32 psi is crazy

[@111dontworry]

Seriously, thank you for doing all of this. The most aggravating thing in the world is going to a forum, reading 60 pages, with 0 resolve. You'll have 3 people arguing off topic, 2 battling out saying their set up did X and Y, and neither of them will have definitive data. If there is a way to get you into a research position somewhere in engineering, I'd sign the petition.

[@TheCarPassionChannel]

Lollll @ the description of the forums, so true

[@TenaciousTentacruel]

Such quality Greg, that’s what we appreciates about you

[@Das-eq2wk]

That's so awesome. Seeing your car reach levels that I could never hit with mine, I can live through you vicariously. The red car hits 500, my car backfires and stutters if I try to hit anything over 5 psi

[@dennisrobinson8008]

Did you correct it? Sounds like a fuel and tune issue.

[@Das-eq2wk]

@@dennisrobinson8008 It just started happening one day a month after i finished my turbo build. That day was like two years ago.

[@dennisrobinson8008]

@@Das-eq2wk You haven't correct it? Which car did you put it on? If it was a naturally aspirated car, never setup for turbos, most N/A computers will let you get away with up to around 4psi! After that the fuel and timing maps will be way off, it will run too lean and you can possibly damage your engine. The cure for that situation is to get a new chip, or a piggy back ecu and/or a dyno tune. If you are maxing out your fuel system, your looking at possibly a larger fuel pump and bigger injectors or aux injectors or more pressure in the fuel rail, and also have the computer tuned for that.

[@Das-eq2wk]

@@dennisrobinson8008 Im not running lean at all. 95 turbo with an MS3X. I believe its a spark issue because reducing dwell from 4ms to 2ms solves the problem until the car warms up, at which point it comes back. The thing is, I have ls2 coils. The misfiring still happened when I was on stock coils.

[@dennisrobinson8008]

[@skylinesandro]

Good video dude. Glad to see you finally graduate to the 6758. I'm stuck until I do trans/diff upgrades at 430whp, artificially kept my tq down in low rpms to keep my driveline alive... Love the data unload at the end.

I worked through a similar decision process with mine, without the benefit of a clear back to back test, and chose the 6758. The car (vvt engined Mx5) is now tuned comfortably north of 450hp.

[@samrigby8308]

Incredible! I have a Kraken low mount and EFR. Taking that thing off and swapping out your 6258 for the 6758 during a dyno session is no joke, and exactly why I'm buying you a gallon of E85. Mad respect, Greg. Thanks for the awesome data. You're an inspiration.

[@chrisdeli7547]

the formula for the exhaust is (horsepower/10)+35 (in mm) so 3inch=75mm is good 400hp crank for your hp you need 3,5 which is for 525hp crank, for me you need 3 3/4 at least and for this set up. this is the reason for your pressure build up. nice job again keep the hp rising.

[@thewheeltroll1833]

Dude you’re the goat for this video, insane!

[@RetrocarStyle]

The 6758 seemed to be just as if not more responsive than the 6258. The boost sound of the 6758 is a lot louder too so it sounds much better.

[@cdsprech]

Amazing work and amazing results! You mentioned the entire fuel system needs upgrading. When do the hard fuel lines become a limiting factor? I'm thinking of the fuel lines that run between the fuel pump/tank and the engine bay.

Man I just want to say how much I appreciate your videos giving me inspiration for what my Miata could become

[@garagecedric]

Great video, the more info the better :) . Do you log the speed on the new turbo? Would be interesting to see where your at now. You clearly showed how important the efficieny is, and why pushing a too small turbo to the limits might not be the best solution. I did many turbo tests in OEM labs developing turbo systems, even in multi million dollar test cells rerunning the base line is kind of important(though chasing smaller differences) , cred to you for doing it!

[@TheCarPassionChannel]

I actually had a few minutes about comp speed edited into this video and I had to take it out. I made an error, I didn't realize the 6258 has a 14 blade compressor and the 6758 has a 12 blade, so even though it was reading 133k, it should actually be around 154k, which is the limit of the 6758. This turbo is very near to its limit at 500, but I'm certainly at least going to take it for a re-tune with the bigger fuel system and see if I can't find just 2.4whp somewhere.

[@YaKiZoBa]

Incredible amount of knowledge on just a single video. Took me a lot of time and money to learn this myself. Looking forward to see how the EFR7163 will perform on my FA20 build. Congratulations on that crazy power and lightning fast boost response!

If your car is overheating in cruise, you should look at upgrading the cooling system. Airflow through the radiator (especially at 70 MPH) should be more than enough to keep the car at a stable temp.

Yeah definitely, one of the many things that needs attention.

"Trust me, I wasn't afraid I just didn't have any more knobs to turn up" I can't even imagine what that thing is like on the road and I own a relatively stock 95 miata and used to sell Porsches for a living. 911 turbo is a beast and you're making more whp than they made at the crank (for the 997's I sold) and you're about 1000 lbs lighter and only RWD instead of AWD.
