Hello guys,
for about 4 years now I've run meth injection on my 335i. I felt before I got the meth that my hpfp was quite weak but this was back before flash tunes and many other things. It wasn't possible to raise fuel scalars back then.
So asking for the advice of the forum members here. How much boost do you think a FBO car should be able to run without meth injection? Purely pump gas and no ethanol. I know ethanol will increase fuel demand in order to hit the lambda/AFR targets. I also know that pump gas will be knock limited. I couldn't expect to target 30 psi. Boost is just a useful value to use because as boost goes up, so does fuel demand. I have a stage 2 lpfp so the low pressure delivery shouldn't be a limiting factor.
However to complicate things I'm running GC turbos. So the volume of air at x psi wont be the same as x psi on stock turbos. Ultimately it should flow a much greater volume of air.
So a strong\healthy hpfp should maybe cope with 20 psi on hybrids? What do you think.
