    if you are going to do a strickly drag car, do an h22 swap and boost the hell out of it.

    :withstupid: H22A booooooooooooooooosted like a fucker, BUT i would add N2O since your only going to use it for drag, but i dont know how good that would be.

    i heard that h22s weren't as good for high boost cause of of thin walls or something, maybe I am just stupid but thats what i heard somewhere.

    20 psi means nothing dude...

    20 psi off a t-.0000000001 will make 2 hp
    20 psi off a t3412412334 will make 2312312312312323123123 hp.

    see the point?

    With your civic hatch shell, is it the lightest one you could acquire? it's good to do some research on getting a lightweight chassis to start out with, and aerodynamics would also play a key role in building a drag car.

    No, you don't understand what he is saying. Pressure and volume are two TOTALLY different things here. A turbo that small CAN push 20 psi, because that is ONLY THE PRESSURE of the volume of air. It may not push a large amount of CFMs, but it sure as hell could push a lot of pressure. Pressure doesn't depend on the turbo, but on the (?)wastegate(?). (This is all "I think" stuff, but I'm pretty sure I think right..)
