2020 Supra 3.0 (2 Port) Max Power on 91/93 OCT Pump Gas

[JonChoivo]

I've read many threads, and watched alot of videos on this, but just want some confirmation.

Im based in Malaysia, where we have

RON 95, RON 97 (91 Oct)
and RON 100 (93 Oct).

I'm only planning to get the max power from pump gas.

My plan is maybe 600-650whp?

I have a 2 Port B58, currently

1) 300 Cell DP
2) BM3 Stage 2 Tune.

Im guessing in order to hit 600-650 whp, i should just go

Dorch Gen 3 HPFP
S58 Injectors or (nostrum Gen 2)
Catless DP
Visconti LPFP
Pure 800

May i know with these, what kind of whp/wtq should i be expecting on 91 oct or 93 Oct?

Thanks

I've been referring to the thread below.

ive read that quite a few times, but i think id prefer to go DI, as it seems much simpler in general.

I think without ethanol it might be a reach to hit those numbers…? Someone can correct me, but I’ve seen similar setups and most 93 tunes are near the 550hp range. It’s tough to hit 600hp on just pump gas even if you have a bigger turbo or a top mount.

Zero need for any fueling upgrades with pump gas, absolute waste of money, and you won't even get close to 600whp on 93 oct with a Pure800.

For Ethanol and DI, zero need for a LPFP for those numbers.

Hmm, sounds like i should just stick to a downpipe and tune, and move on?

As far as I have been able to learn, the best you will be able to get on pump gas alone is maybe 550WHP and that is (besides what you already have) with an upgraded intake manifold/intercooler, upgraded turbo and a good tune.
That is basically what I am aiming for. And to be honest, if you are driving the car on the road, with that much power, there would be VERY few cars that can keep up.
You also will need to change tires to the stickiest and widest you can get,and even with that you will have trouble with traction on the first 2 gears at least (unless you go with drag radials)
Lots of people also code it so that it always starts on second gear since first becomes pretty much unusable.

What if you used s58 injectors, upgraded hpfp and a pure 800 only on 93 octane? Would the upgraded injectors make a meaningful hp increase?

Only ask because e85 is pretty scarce around here.

I think compression/knocking is the main problem.

Probably PI is needed to hit 600whp on 93.

Added fuel capacity doesn’t help with knock. Higher octane does. PI is useless on pump gas for this goal.

Cliffnotes: Pure 900, do88 MERA manifold and do88 aux cooling, PTB clutch, reflex Port injection on a flex fuel tune.

Tuning not yet finalized, but so far laid down 612whp on 93 octane only





just a quick reference for guys wondering about the max power on 93/91.

Keep in mind that is a lower compression six port Supra and a much larger turbo than a pure 800. Both advantages on pump gas. That particular dyno has also historically been pretty “friendly”. Also, don't think you are making that power on 91 octane.

That particular car is also on PI because it runs ethanol as well. 860whp on E77.

I honestly wonder how does the F80 get 888HP from a Twin Turbo V6 3.0, on pump gas, while making it drivable.

The drivable i get it, electronic turbo plus, electric motors to reduce the lag to zero.

But 888 hp on pump gas while likely being pretty reliable? Im really curious.

Not going to entertain any comparisons to a $6 million Ferrari F80.

I do suggest reading up on compression ratio, chamber and piston design, turbocharger technology, valvetrains, Miller cycles, etc.
