Makes me feel even better about running my twinscroll hx40s etup this year. I'll jsut wind out the h1c with the improved twinscroll setup and report the numbers. Then come back with the hx40. As of 2 days ago, it's just done
685whp on a dynojet with the .55 a/r bep housing and hks 272 cams. So I know the original holset housing will give me more than what I want.
. . .Oh, I forget which cams you have?
. . .Nevermind, BC 272s from your tuners thread. . . 212-213 duration does so well with the sirius motors it seams.
