After installing the 317's, I was able to add even more timing down low and pulley down for more boost. I now have excellent drivability and more boost at all times. Win/win.



    This is not true as well and very misleading. The Edelbrock is an excellent piece, however it is far from complete. There is quite a bit that has to be done for an LS6, and the Edelbrock HEX, pump, etc either do not fit our application or are inferior pieces. Don't get me wrong, it's well worth the effort, but far from being bolt on.



    You're not going to find one. The cam I spec'd has 0* of overlap. With a bigger blower, closing the LSA of the cam a bit will make more power than running traditional "FI" negative overlap cams. You don't have to worry about losing boost...just pulley down if you need more.

    OP...do you have the Whipple yet? Or, are we window shopping?
    Im not here to argue with you, a recent quote comes to mind,your entitled to your own opinion not your own facts .I can back anything I say with facts from numerous cars weve done but im not giving the only answer ,just the answers that's worked for us. Good luck with your build sounds like your on track

    That's odd. Edelbrock thinks the answer is no.

    We are waiting on sponsorship info so I don't wont to go into detail but Eldelbrock doesn't have a CTSV or GTO kit,we have a 99% kit with parts we order from Eldelbrock. We have done a few dozen CTSVs..

    Could you post some dyno graphs of the fore mentioned cars that have a cam similar to mine and the tvs2300?

    Re: cam sufficient for a top mount blower?

    I'm guessing this all applies to a rear mount tt set up as well? If that's the case I suppose I will have to go n/a. I don't believe I would want to get into a stroker kit. That should just leave me with h/c heads, under drive pulley, intake manifold (possibly fast 102 plus supporting cai and tb) and e85 tune? Anything else? Any other ideas for an intake manifold as the 102 may not be the most cost effective?

    I am having quite a bit of trouble believing what Hendrix is saying. I thought I would be interested in doing an e-force setup on my 408 with ls6 heads after reading that, then I remembered over on ls1tech, the e-force build thread.

    Re: cam sufficient for a top mount blower?

    Which E-Force build thread...there is mine and the one from "Psychobillycaddy". I copied my build on here, but on LS1 tech it's in three parts....when I got the parts, the initial build, and now installing new 317 heads and cam.

    Hendrix - I am a little puzzled by your statement. I am speaking of facts, very well documented through all three of my threads regarding the E-Force. I guess you don't remember when I bought my E-Force from you and told me there were no plans for kits and that you did not know what was needed to complete the install other than the LS2 tensioner. Not complaining, you got me what you promised at a great price, but very very far from a kit.

    Since I already posted every aspect of my E-Force install, can we see yours?

    A good FI cam has a moderate duration for intake, a longer exhaust duration with moderate lift 0.550-0.625 and a large LSA 116 up to 121. The engine doenst have to work too hard to suck in the air anymore, the SC does all the work, But your exhaust should be longer to give it a chance to exhale...

    Whats wrong with the LS9 cam? its cheap, it works, and gives you great power. If you want to increase your output then get the GT9 from LPE noticeable idle, but awesome power.

    Yes you may have received one of the first few and as I said at the time it took some finishing .Since then weve done a lot more and learn as we go,everyone has been happy with what we send them now...Your setup is working for you and that's great,and that's what matters for you. I have built and help customers build positive displacement setups on a weekly bases,mostly maggies which uses the same TVS rotors and are very very similar to the Eldelbrock... I simply gave a member my advise from years of working with these type blowers,not to discredit you and your results. I have built,help build the highest hp Magnason builds to date ,Magnason sends guys to me weekly to help them with there build which we enjoy doing.IM here to pass on things that have worked for us in hopes to help other members along,there free to choose a different path of coarse. You my find intrest in a Camaro in the most recent GM hi tec mag that has the record holding Eldelbrock on it,right at 800rwhp ,that's one of our dealers and I think we have a mention or two in that one as well... As you stated I delivered what I promised,and im glad you've made the most of it.

    Pretty sure a big twin screw isn't going to dog down low with lowered compression. Keeping a 10.9:1(ls2) compression ratio and only running a couple pounds of boost sounds like a waste of a big blower if you ask me. Might as well stick to the mp112. Only way to up the boost on a big twin screw is to drop the compression, go race fuel or be meth dependant, if you want to still have any timing worth a damn.

    I agree.. but I'm thinking I may be going n/a. Anyone have experience with the advanced inductions 226, ported fast 102, 102 tb and so on..?

    The lack of misspelled words and use of punctuation leads me to believe this is not Thomas posting to the boards. Whoever you are sir, let Thomas know he made a smart hire.

    Make sure it's an LS2 style throttle body and you'll be good. An LS3 based throttle body will NOT work on our application.

    Is that because of the tps?
