Achieving 750WHP+ Without Port Injection - A Plug and Play Solution for 2020+ Supras

[Awad]

Head spinning. Please make it stop!!! Wagner manifold looking better and better. I’m sorry but I would have thought the turbo alone on a stock fuel system would have made over 500 on gas.

I was on the wrong map ! Should of been around 520 ish

The HPFP crashing is definitely not great.

The crashing is a tuning issue or a HPFP issue ?

The HPFP is the issue, it does not flow enough at low rpms as razorlab said. The tuner can try to tune around this HPFP issue by lowering boost at lower RPMs, where you run out of HPFP, to lower fuel consumption (lower power).

I believe in you. You will get the kinks worked out and get it running right. It takes time.

to be fair specially with the tuner , this guy is amazing responds quick and always helps me . I discussed with him all the issues we talked about here and he explained everything . We are trying new things and we are treading carefully but with a goal in mind . This is all new and it’s hard to perfect it first try but we are working kinks out . But under normal situations I am sure everything would be very different .

Yes.

What was explained, regarding why the tune was suboptimal? Curious

@Awad keep it up. You will figure it out one way or the other. Either your going to be a hero or a zero but you won't know till you try. At least you will be able to either confirm or deny if DI is as good as PI.

 

[razorlab]

@Awad want to make clear my recent feedback has been me trying to help how I can, not being critical.

I personally think it's great you are trying all of this. I also see you stopped writing your posts like Don Draper, that has been helping.

Or run less ethanol. Or don't and get bigger injectors (To stay in the DI theme)

I have a 100% stock fuel system and now run E45 with 27psi or so out the top of the RPM range.

So far however , not fuel limited

i saw and I really appreciate it , I understood I did a mistake in the writing style and now just being me . Thanks for the feedback

Your log says completely the opposite. That HPFP is pinned max as soon as you get into boost.

Here is what the tuner said regarding all the things being discussed are :

1- dyno is not loaded
2- HPFP crash “Yeah I saw that. It didn't actually crashed but was on the limit at 126⁰”
3-On the street ur turbo duty is in the 80s
4-So we didn't have time to fix ur stft on the dyno at all. Coz ur car was never tuned for 29 psi before. Ideally I would like to have ur stft closer to 1. Instead of 0.85 or .75 the injectors are quite big . They act like u have pi. So will have to take out fuel out . But the actual afr was still inline with what I wanted so I just focused on boost target.

Check this out. See how your HPFP angle maxes out down low at 126* (orange plot), and then crashes (black plot), then the car tries to save itself by dropping boost?

Now, check out your HPFP angle at higher rpm with the same amount of boost. Way less angle, right around 100*. If I was tuning the car with your current hardware, I would ramp up the boost down low to higher boost up top, you would lose some torque down low, but would gain power mid and higher up. You would probably be closer to what Spoolin' has been saying is max for what their HPFP alone can do on E50 (670whp). This is also how I get away with 27psi out the top on my track tune with E45 on a fully stock fuel system.

Will tell him about this
