Finally got my car back to the track. My old setup was a Paxton, E85, 3.33 pulley waste gated to 11psi (yellow slip). Last week, now with a built motor, 3.33 pulley and no waste gate (white slip). I gained just shy of 3/10ths but MPH was nearly identical, which I find weird. Also, I asked my tuner to desensitize the knock sensors because Paxtons love to knock between shifts with a manual car. Not too worried about knock with E85, so tried it out.
I'm happy gaining ET but was thinking the MPH would be higher.
Anyway, just thought I'd share.
