    Depends on which one you get, the cam & what size the motor is. The P1 is good for about 10 on a 346, the D1 at least 14. Then there's the F1, F1A .... big time boost

    I just talked to EPP today, I think im going with the LQ9 heads with D-1sc-1 kit. With those heads my comp will be around 9.3:1 and I will start off at 8psi of boost. Later I will go with a forged bottom end and run a little more boost.

    I have the same general plan: run it for while & not get too greedy with boost then build another motor later. With the LQ9s you might be able to push the boost a little higher, like 9 or 10 psi, that would be a rocket

    I don't think a roots style will work on an F-Body as there are clearance issues at the windshield cowel.

    You'll never have that problem with the boost you are running plus there really isn't allot of facts to back this up. I am building a 408 with a single front mount turbo and will be running a LS6 if that answer's your question. As for boost on stock block, I'd go 8#, many go 10# but its all in the tune. If you are gonna run stock CR, than I'd stay at 8# myslef if you get some 317 on there then I'd step it up to 10#. A question like this is always gonna get different answers but to me I'd stick at 8#, get a blower cam and call it a day. If interested, I have a brand new one for sale right now since plans changed. Pm me if interested.

    i thought there were no modsd for a magnacharger on an f-bod, they bolt right up, the KB's are the ones that require cutting.

    check out a build in the forced induction section on LS1TECH user name badmonkey, he jsut finished a mgnacharger build on his maro and it was pretty extensive. Finally got it running good but allot of trouble shooting, etc. Put down crazy torque like over 400 at 1800rpms

    i didnt think that u had to do any cutting with the magna..
    i may be wrong but i printed an article on it and it didnt say anything..but they may not want you to know the extensive work...

    but i figured if it was for an f-body it would fit...

    Anything can fit if you got the money and time. An F-1 won't fit withought getting out the grinder on the block and moving the rad up a bit but it does fit
