What does it matter if I am, I simply asked a question about E85 and fuel pumps. I want to know how much E85 a wally 255hp can support before you need a booster pump, dual pump intank set up, or an external pump(A1000) etc...and if you must know I am running a 10.5:1 comp piston with a head that has been decked 3 times and a S20g turbo. And E85 can make more power on a stock car as well. In my del sol I had a bone stock B16a(intake to header stock) made around 130 whp and after switching to E85 on the same set up laid down 151whp and 111wtq. Thats the problem I'm running into...too much he said she said shit about E85..
