How much HP can I expect by porting my TB and intake?
If you are thinking about doing this yourself and have no prior experience with it, you might want to reconsider. That material is awful thin in places.
That said, I have seen reports here of 10-12 RWHP following installation of a ported intake manifold.
My FAST is in his hands at this moment, I also am purchasing a ported throttle body and am wondering what the gains are if any. I thought I read 5hp somewhere.
I had american racing headers, ported intake, ported throttle body and tune by Tom Wong. The car dynoed at 375 hp on a mustang. I would guess about 385 on a dynojet. I also realized a slight increase in fuel economy. I would not expect a huge increase in HP from porting a throttle body.
Stock intake manifold to Formato ported stock intake manifold was 9RWHP and 11RWTQ gain. Dynojet 248,SAE smoothing 5. I didn't port the TB, couldn't see anyplace to make major gains.
I got 15/rwhp and 15/rwtq from the ported intake. Didn't dyno after the ported TB. Tuner said probably not HP gains on the TB, but the torque would be more in the lower range.

True....my dyno experience on a ported LS2 TB...a definate kick in the rear on the bottom:
