My buddy says he did both, with a dremel and says he feels a diff on the butt dyno. Is it possible to get much on his LS swap?

With a dremel on a TB? not a chance. On an IM, highly doubt he would ever feel it in the but dyno. At best he might gain a couple hp but not feel it. Ever hear of the placebo effect?

 

this guy said he used a drill w/ a whole set of cutting or sanding stones...he said something about needing a bigger throttle plate cuz it was the bottleneck in the entire intake stroke of the motor ie: everything else is ported huge, according to him, and yes, placebo probably was the only thing he felt.

 

I just had my car dynotuned two days ago. The person that tuned it told me I could get quite a bit more power out of my built GSR if I had a larger throttle body (either after market or S2k) and if my current Skunk 2 i/m was ported to match it. There are definitely power gains to be seen there; it wouldn't be the first place to start though with so many other power adders having a higher bang for the buck.

 

Porting the TB and IM? Is there any power gains?

No.

 

well, technically, you are not gaining hp, you are just freeing up hp since your car is breathing more efficiently

 

Take a look here. This a post from some time ago that might shed some light on the matter. Keep in mind this porting and polish was NOT done with a Dremel.
