I'm looking for rwhp dyno gains from a hand ported TB on LS1,LS2 and LS3. If you could give me the rwhp you have seen on the dyno from a hand ported TB please post the info.

 

i take it you already tried searching the dyno section above?

 

Iv always herd it don't make that much of a diff in HP prob like 3 at max, just makes the air flow better.

 

there is a thread on it, i forget where. Ill see if I can find it for ya Chris

there is at least one other thread (ive seen it before) but i cant find it

 

^Thanks

 

FWIW, I absolutely did notice an immediate difference in mine from stock to ported. mostly throttle response (VERY much more crisp) but with a hair more power (very little but noticeable non the less, between 5 and 10 whp)

if ya want ill port yours for free, my die grinder makes it about 1 hour vs. a dremel which takes FOREVER
