saw the tvs on pump gas compared to the m62 e85
curious to see what numbers people have put down/track times
anyone think its worth it to go over to e85 from meth or wait till i get my tvs to do the swap

running meth injection is not the same and switching your main fueling to e85. you will see quite a difference running e85

I dont have any apples to apples comparisons, but I can chime in with a little info at least. Back on stock blower I ran at the track with my current pieced together intake, vibrant header and 2.5" dp, stock catback to a straight through 2.5" muffler, on a 2.8 and meth with 22* of timing (was cooler out so I backed it down a degree or 2 from normal tune) and I ran a 13.8 @106.7 with a 2.2 60'. I went back the next year with the only changes being a hahn 3" catback, 2.7" pulley, and E85 tune on 25* max timing and ran a 13.6 @109.7 with a 2.25 60'.
