I’m running E85 and just over 600rwhp NA with a stock 85mm MAF and stock Ti catback on my car. Speed Density with an better exhaust and it might have 620+ in it. With boost E85 will help you even more. And with all the motor and plumbing in such a small space the cooling effect will be huge for you as well. Seriously, I thought somebody said there were pumps in your area, you should think about it. And you said the fuel system can handle all you can throw at it, so hopefully you won’t have to make changes there (figure you need roughly 30% more fuel). If you’re over 60% duty-cycle on injectors now you’ll want to bump those up. FWIW I’m running 80# injectors to support my 600rwhp, but I’m actually really low duty cycle (which I like) eve on the E85. > > -TJ Please… race gas in any car you drive on the street is absolutely stupid. Same with E85, its different for cars that are E85 compatible that mix, but if I have to have it to be able to get on it safely its also stupid. I’m not sure people understand the definition of a street car. I want to be able to drive this thing anywhere, no matter where I go and not worry about being able to find E85 or race gas. --- _[View the full topic](https://forums.speedlife.net/t/93-rx7-ls2-project/196180)._
