GR Supra 101: Routes to big power

[_Sp1ral0ut]

. The new Pure 800 is still two weeks out though I guess.

Always, my friend. Always

car is currently in the shop to get the pure 800 installed.
I received a base map from my tuner for my setup.
I’m going to do a few dyno runs. Can I also pull logs while it’s on the dyno or are the logs on the dyno not indicative of real road pulls?

i have a dynojet and mustang dyno available in my area

Most tuning is done on a dyno. Yes you can use it for logging

Mustang is better as it has more accurate load but either would work. Also recommend logging on the street after.

Got my car back today, pure 800 and intake manifold installed. DI only setup.
Custom flex fuel tune from Sameh, currently running e50 which is the max according to him.

All I have to say is that you fuckers with a big top mount are insane. I’m losing traction left and right with this thing. I’m so used to the stock turbo characteristics of it kicking in at around 2k. There’s definitely some lag but the turbo kick is WAYYYYY fucking harder. I haven’t even given it WOT (im a scared little boy). Can’t imagine what a top mount feels like.

Excited to take it to the dyno next week and get some revisions done.

Now imagine it in a Supra 400-500lbs lighter.

Do you have upgraded HPFP and S58 injectors?

Extra weight means more traction those light supras must fly

yeah dude, s58 injectors and ds25 hpfp.

Are you still running DI? If you are, do you have line pressure bump activated on XHP? Right now I’m running stage 2, only custom settings being gear display.

I'm likely heading down the PI path considering the goal of around 750whp.

I think I'd still want to upgrade the HPFP though for sustained track use.

Zero reason to upgrade HPFP if you are going PI. Like zero.

Is there really? What if you're leaning into healthy DI contribution for knock control in 100+ weather?

wat?

 

[TBK]

wat?

Sigh. I guess my "logic" isn't logicing. I just want to go fast and have nice TE wheels while I'm at it. Why does everything have to be so complicated.

You might be referencing that DI has better knock resistance? I don't think that will change unless you stopped using DI all together. Plus, the OEM HPFP will have more than enough head room with PI for the numbers you are looking for.

At what point does the OEM HPFP run out of headroom in that scenario?

Probably never.
