Gains from ported TB?
Gains from ported TB? I am trying to figure out what to do next. I have a lid, free ram air mod, LTs, and cat-back. What kind of gains would I be looking at with a ported TB? Should I just start saving for a cam?

there is a thread on here, where a guy claimed 11 rwhp gain from a ported TB.
I ported mine and did the bumpstop mod, both where a noticable difference.
Dont expect a ported TB to be a huge difference, just because you are porting the TB, the intake opening and TB opening size does not change.
save the $150 that a ported TB cost and place towards a cam. Port and polish the TB yourself. Its easy and do the bumpstop mod!

I did back to back dyno runs before and after mine (Texas Speed)and gained 0 rwhp & 0 rwtq. My stocker did open 100% already though. For the cost I would do an Underdrive pully. I did the SLP and gained 14rwhp & 12 rwtq.

I'm guessing this was with the bump stop mod too?

wat is the bumpstop mod?
its shaving the throttle stop, it allows the plate to open more, because the plate doesnt exactly open all the way during WOT......TB porting gains are typically 5-7 on stock cars, like bo's chart.....i added a ls6 manifold and got about 10 from it
