I'm hearing figures that sound untrue (like 50+kw gains)I have a BF II XR6T with Process West TB relocate, piping, PW front mount, Hi-flowed gt35/40r, PW surge tank and 044 pump, Cold air intake soon to be replaced with a race box - tuned to 350rwkw. ZF is about to be rebuilt and im thinking that converting the engine to e85 full time could be the go to squeeze a few extra kW out of her while its in getting the box done.Feel free to let me know what you guys think....

Generally feels a lot better, car runs a whole lot cooler on the track tooMainly did it for the reliability and cooling, but bonus power is pretty cool. Last traxkday I used low boost all day and felt way better ro drive than old hi boost 98 tune Link to comment https://www.fordxr6turbo.com/forum/topic/88028-power-gains-from-e85-tune/#findComment-1466295 Share on other sites More sharing options...

Might have to go to 1000's I think and as suggested another 044 pump at the surge tank.

I would say with the right package and fuel system, the right car could go from 400 - 500 rwkw with a change to E85.
