I know people on this thread are claiming 4-6 and up to 12 RWHP.
to them I say SHOW ME THE DYNO SHEET, otherwise you are being a silly person and speaking nonsense.
The ported TB will greatly improve throttle response, but I have yet to see any RWHP gain from this mod alone
That is kind of where I was going after the "must have" comments. I know I am old school (because I am old), but I never saw anything that was externally bolted on to an engine that gave a worthwhile HP increase except nitrous, superchargers and turbos. Thanks for the feedback.
