    you'd have to understand what a air to water intercooler does for a gas turbo motor this fella didn't run a intercooler at all. take that same set-up and add a air to water intercooler that has a 130-150% efficiency, and the same combo will make a shitload more hp

    Just as a comparison that combo I told you about at 3680 lbs traps 164 at the same 20 lbs.

    chris, got any experience grinding blow thru cams? figured since i was buyin off the shelf heads, not touching them, i could get you the flow numbers for the grind.want to stay under 700lift, somewhere around 670-680 or less would be nice and easy on the valvetrain.

    good deal on the turbo,no on the little c.i. go BIG daddy GO BIG
    self is too high, and his valve jobs wear quik, grice is the man around here for porting cheeeeeaaaappp toooo.i just want a basic longblock without wild parts. keep it simple, keep it reliable, keep it on the lake no major porting other than a port match.

    when ya go big cold boost, cubes matter less than you'd think. between a 383 and 427, you're talking maybe a 100-150hp difference with the same induction set-up, but 2k difference in the build.


    anybody wanna buy a tx19? i'd like to order some parts
