I just don't like TT on inline motors. Can't say as anything is wrong with it, but a Supra would be an emotional purchase so I'd rather it play fully to my whims.

Not a 2021..but this shows the 2020's potential with just a tune & then some ethanol mixed in.

Same dyno. Same day. Tuning by STIMikey.

Stock baseline on 93: 330 whp & 392 lb-ft
Stage 1 tune on 93: 400 whp & 498 lb-ft (+70 whp & 106 lb-ft over stock)
Stage 1 tune on E50: 476 whp & 609 lb-ft (+146 whp & 217 lb-ft over stock)
Stage 1 tune on E70: 496 whp & 631 lb-ft (+166 whp & 239 lb-ft over stock)



Fuel pressure started to drop on E70 so they decided to stick with the E50 tune until they add a downpipe, meth injection & retune.

Mercy. Looks like I'll have to swing by a Toyota stealership when the 2021's are released.

no manual, no care.

Are you guys sure the trans can take that kind of power and torque from cranking up the boost? Obviously it has some margin in it considering the new power increase from the factory, but if it blows after tuning, Toyota would likely refuse warranty claims. It might need some new coolers to be reliable.

I'm certain it's past the specs on that tranny. A cooler is a must as is turning it down for lower gears for daily driving. Track work will kill it dead on that tune. Also 275s are not enough tire.

Yep, Stage1 is what I am running on 93 oct gas and that is already more than plenty for an older guy like me. I really like the sound of the stock exhaust too. I'm going to try 285's next when the rear SuperSports are worn out. I ran RE11's on 285/35 size on my 370Z long time ago and even that wasn't enough grip off the line.

I agree, I wish there was a manual.

There are several 2020 Supras with modified/upgraded turbos pushing 600+ whp & 700+ lb-ft on E50 & Meth. A few are running the 1/4 mile in the 9.7-9.9 sec range @ 139-142 mph. Even with slicks and hard launches the trans seems to be taking the abuse so far. They seem to break axles first.

Wow, those are some ridiculous numbers! I've only seen a couple around my area and the last one had an annoying 'snap, crackle, pop' tune on it to make 'racecar' noises at every lift of the throttle in traffic. I'm sure its a blast to drive though.

I was talking circuit work. But yeah, holding that power on stock slushbox is a short game. It's all for fun.

I'm pretty sure Sti Mikey has completely ditched the Subaru platform and went full Supra. All I see on his IG is Supras on the dyno and he's posting some incredibly impressive numbers.

His wife has a supra running 9's

It's almost like they are making it a great candidate to mod for big power gains ... where have I heard of this before?

Regarding the transmission holding power; there's a tuner out of NY pushing 800 hp and was getting slipping. He claims to have needed to dial things back to 650'ish to make the trans. slippage go away. He does not track it as far as I know so who knows how long track use and these power levels will take teh abuse.

That's not from a tune, that sound is stock when in sport mode. Yes it's a bit juvenile at times but I love it. Plus you can make it go away by just putting it in normal mode. The 21 model tuned these crackles and pops out.

Loving the traction control in this thing. When half off; it will hold a beautiful 30 degree sideways drift going around the rotaries by my house........in Mexico.

Subaru crowd is turning into the old Honda crowd or the 1st gen Miata crowd. You've got people with high mileage cars and small budgets. Upscale end of the tuning market is how you stay in business. The kind of people who can afford a Supra and choose to buy one probably work in areas that are less affected by the COVID shutdowns. 20 something 15 year old WRX owner is more likely to have been canned.

I'm assuming Toyota/BMW is using an 8HP70/8HP75; they're spec'ed for 700 N.m. to 750 N.m.; that's about 515 ft.lbs to 550 ft.lbs.
So, how much power can be made by maintaining around 550 ft.lb of torque all the way to 7K RPM? :-)

Oops. I assumed wrong; it's an 8HP51. Ouch. That's a 500~510 N.m. / 380 ft.lb tranny. Ouch.

The 8HP51 is most likely a bit lighter than the 8HP70 though.
The one in my V8 Charger is at least 200 lbs and the ZF 3.09 LSD that goes along with it is at least 90 lbs.

Should hold up just fine. Those trans are really well developed and I believe BMW is planning to use them in the M3/4.

Would still prefer the BMW dct though.

The Supra spec unit is lighter as neg posted. It's the lower torque unit. The higher torque units are heavier, which would likely go into the M3/4. I think there's a ~300-400 lb weight difference between the M3/4 and Supra. But I think the M3/4 are going AWD so even more weight? Lot of weight and power and grip.

Is M2 going 8AT setup like the Zupras?

I really like the new Supras. They grew on me for sure. I thought my next drool car would be a V8 but this is swaying me for sure. Now just gotta get my career back on track

Donít believe so. The M2CS is supposed to be DCT. I wouldnít be surprised though. I think youíll see more people start leaning towards the M2 over an M4 but could be wrong.

Iím probably selling the M2 in July or August but it has been one hell of a fun car. I put on 10k miles roughly in the last year with probably 7500-8000 miles being spirited long drives. I think itís the blue color but I get everyone from really young kids to old women who look like they couldnít care less about cars complimenting me on it.

I wouldnít mind buying a clean e46 and having it professionally and properly painted Long Beach Blue.
