thinking of trying race gas over E85
thinking of trying race gas over E85 I only have 65# injectors currently and have them maxed out running e85. I am thinking that if i switched to race gas for the track that I would be able to make more power. Im thinking this because of how much more fuel e85 requires compared to running gas. More room with the injectors equals more room for boost. Am i correct in thinking this?

1) As you stated, it requires more volume of fuel to support the same power as gas, in-turn maxing out a set of injectors at a lower power level than gasoline.
2) Because you're burning more fuel volume you're getting more exhaust gas in the combustion cycle, which will make the turbine side choke faster and lower your overall peak power. You will however spool slightly quicker with more exhaust gas volume however, there is a tradeoff with the power you will make.
However, nothing will beat e-85 in terms of cost and running high hp. I would use e85 if I was spinning a slightly oversized turbo for my motor, it'd spool quicker and have better street manners. But for maxing out a combo, I'd use race gas.
There are two reasons why switching to race gas will net you more power....

Thanks for the info! What kind of timing are you guys running on race gas?
You dont need 160lbs. I just picked up a driver and a set of 83lbs injectors. They go in this week and on the dyno next week. Mine gets alot of street miles also.

60lb injectors will support 1k hp on gasoline. You don't need anymore than some RC 75's or 84's; and even then you'll have some cushion.
