[Build Thread] -- Journey to 700+ WHP [Supercharger]

[Senna-F1]

Duty cycle too high... I had Eugene tune my car too, and we never even bothered with e85 because I was already at 80% on pump gas!

I have 1050x and Walbro 485

Is your FPR Working? 442 WHP should not be needing 90% duty cycle. Hopefully you figure that out, but it sounds like maybe your fuel pressure is not raising at a 1:1 ratio.

I spoke with Eugene and he said:

It was checked. The duty cycle is around low 80s at 6200 RPM on e75. And with very reasonable fuel target. The increase in duty was also linear.

I didn't start maxing out my 1050x's and walbro 485 until I got into the 600whp range on e85.
