    So pretty sure I am at the limit of the stock fuel system or close now.

    next step is 1000 cc injectors. if I swap to that set up with stock pump can it handle the e85 with 18lbs f boost and 9100 rpms?

    if so what kind of power/rpms can I expect to see form running e85 vs 93 on same set up?

    Also curious about the power gains. I just went to a et18 and would love some e85 that is right down the street from me.

    I first started playing with E85 on my SS FZR back in 2011. Started with a downloaded Riva base map on a vipec and 1000cc injectors with an ET18 wheel. Others laughed! That tuned combo back then would get you 92-94 mph. With todays pumps and hull mods 100 is not difficult with that combo. Took me years to learn how to tune the vipec with E85. Base maps are just a start. The biggest difference in gas and E85 is the latter cools the incoming air charge AND allows tuner to add ignition timing. The more boost/cylinder pressure, the greater the gains can be with E85. With 18 psi+ boost I would use the bosch 210 injectors. Great to see so many using it now, far superior fuel, and CHEAP!!.. Gas/Racegas boosted AFR. 12.0 target. E85 boosted AFR 11.2 target.

    So my question is if a said ski is dialed in on 93, and you swap to e85 and dial it in.

    how much gain can you see from the adding timing?

    100 RPMs or 300 or what?
