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

 

im curious about this too. im getting my car tuned very shortly.

 

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

 

what type of cans can typical be seen between e85 to 93/meth 75/25

 

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'.
