The car runs but is headed off to the tuner soon to finish the tune. I hope to be in the 325-350hp range.

E85?
Could be cutting it close with fuel.

Im in the same boat idk where i will be with fuel.

I wasnt planning on it. Its going to be a 93 tune.

Probably shouldn't need it at 8.5:1. But you'll certainly make more power on E.

Mx5lammed

Thats what i was thinking originally. But im willing to sacrifice a bit of power with 93.

I made 296whp/302ftlb on a 84.5mm 8.5CR wiseco motor. I have a much smaller turbo gt2560 and 550cc injectors on 93. I think you should have no problem hitting your goal.

I hope to get there. I will definitely update this thread when it i finish the tune

So had the car on the dyno recently. We ran into some fuelling problems. The car isnt able to max out this turbo 🙁. She started leaning out pretty bad with boost we were requesting. But it was very much reaponding to timing and boost. So we had to back the tune off until i can figure out why i dont have enough fuel.

Does anyone have any suggestions for what could be happening with the current setup?

We made 300hp 270tq holding about 19 or 20psi. We were slightly above 300hp 300tq but it wasnt safe so we couldnt explore what it could do.

Could be the dw200. I had used that pump on my car and it failed in less than a year. I put a walbro255 in it's place and it's just a better pump. Even with the NB returnless fuel system you should have enough fuel for 350whp as long as your pump can keep up

If your tuner couldn't tell you if it looked like a pump or injector issue you should probably find another tuner.

Do you have any logs so we don't have to guess?
