    Well ZZP runs a 3.0 with O.D. so equivalent to a 2.8 on their Gen V record car with 464whp. Many ppl have run a 2.55 though.

    MEH.


    that is all,

    If you're running smaller than a 3.0 knock free on a gen V you need a better blower.

    Hence why I said a 2.8" is max. ZZP knows. Just because you run a 2.55" doesn't mean its a good thing. I bet a 2.8" GenV car will out run a 2.55" GenV

    Ya...10.5:1 doesn't have anything to do with it...neither does the cheater gas.

    Note he's only running 10 lbs?

    No one here knows how much of the cheater gas is making up for the high compression here.

    Once you establish that then you can begin to compare it to other cars.

    Apparently its good enough to make up for a couple FULL points of compression LOL

    Koenigsegg CCX - Wikipedia, the free encyclopedia

    8.2:1 CR = 806 bhp, switch to E85 and it makes 1018 hp.

    26% more power... Just by switching to E85 and cranking up the boost.

    The only changes to the engine are modified fuel injectors, upgraded fuel lines and piston rings and a higher boost setting on the superchargers.
    two centrifugal S/C's + a redesigned and fully built ford modular 4.6.... I say its a lot of win.

    I'm focusing more on the 26% more power part.

    This doesnt seem right E85 and ? boost= 1018 HP???
    The question needs to be E85=?HP @ X PSI
    or regual gas=?HP @ X PSI.
    You say cranking up the boost AND E85 = 26% more power, IMO what really matters is E85= what HP with the SAME Boost.

    Gaining 212 HP from ONLY E85 seems insane.
    I understand its better fuel but its not nitrous like the big 212hp gain!!

    its 8.2:1 compression, so boost is easy to add if you have the octane for it.

    Basically all they did was switch to higher octane fuel, add fuel, add boost.

    Boost is irrelevant because the higher octane let them run that extra boost.

    Thats like saying "lets compare 91 octane to 105 unleaded race gas, but lets not take advantage of the octane" it defeats the purpose of the experiment.

    Remember the car already made 800 HP.

    switch to E85 and add boost, +26% power.

    You just restated everything in your 1st post E85 AND more Boost,

    The question is what HP on E85 vs. Regular gas?

    And I see no problems changing the boost level but its throwing of the results. Its not apples to apples no matter how to look at it. Same things is like me saying I gained X HP by doing a pulley drop. Well thats pretty obvious its going to make more power if its making more boost!
    So still I do not think for a seconds E85 alone would make a difference of 212 HP

    you dont get it at ALL do you.

    Lets say you have a grand prix GTP thats stock but tuned for 87 octane, no knock.

    it might make 230 crank hp.

    put 100 octane race gas in it and it will still make 230 CHP because you didn't TAKE ADVANTAGE OF THE OCTANE VIA TIMING OR BOOST.

    same applies to switching to E85.

    No no no your not getting me at all Im askin what is the HP?

    E85 @ X PSI tuned for E85 ???
    vs
    Regual @ X PSI tuned for regual gas??

    Whats that difference?? Leave the boost alone.
    What your talking about is E85+more PSI=X HP
    If you changed fuel and retuned it sure in the hell wouldnt be a 212 HP difference. Some gain because of the higher octane and tune being the only difference between the 2.

    Well in our cars apparently 1* of timing is worth 2-3 HP so maybe 10-30 HP at most.

    Assuming you were running 16 and bumped it up to 26 you could theoretically gain 30 HP.... But wtf man.

    who switches to a higher octane fuel and doesnt add boost?

I just dont wanna wast money if i dont have to.
    Any answers?

    its not for people who've run outta pulley options. its just that the gen v calls for different size pulleys because it is more efficient. it moves more air than the genIII. ultimately putting more stress on the engine.

    Ok so basically a gen V is better than a fully ported gen III no matter what.... hmm so are there gains to be had in porting the gen V or is it a wasted effort because of the higher efficiency?

    I just reread your post.
    Simple answer:

    E85 will make more power, if not from just timing advancement alone.
