E85 on maxed out turbo?

Would e85 help out in hp numbers if the stock ra turbo is maxed out around 270whp?

I'm admittedly uninformed but, no why would it? if a part maxes out at some value how would changing the fuel type help?

e85 allows for more timing and cylinder pressure. I have not had the pleasure, but I would imagine even with the tiny RA turbo you could max out the MIVEC intake and add a handfull of degrees

I gained 25hp and 60tq going from 91 to E85
A big chunk of those gains are from the initial boost spike but the car is obviously faster on E85

ya i know e85 explodes much faster so wouldnt that require more air then cause there more gas going through?

stock ra turbo?

Actually E-85 burns slower than regular pump, that with the additional cooling properties in the ethanol allow you to run more timing/boost without knock.


Yup, Stock RA turbo with AEM Intake, X intercooler, UR upper & Lower pipes, 1000cc injectors, Ultimate racing turbo back exhaust, and a 3-port

233whp/ 258tq on 91---24psi spike, tappering down a lot by redline
258whp/ 322tq on e85--27psi spike, tappering down a lot by redline


This was on a Mustang Dyno
Didnt get a baseline but other stock Ralliarts have dynoed in the 190-200WHP range.
