Hand Ported Throttle Body

I hand ported my throttle body today and went to the track tonight. The throttle response is awesome. Previous best time was 12.007 @ 115.2, now with PTB new best is 11.93 @ 115.19 into a 10-15mph head wind. I guess I am a member of the 11 second club now. This is the cheapest mod I have done so far with great results!

The car didnt pick up any mph, the true tale of hp. It just ET'd better. You just made a better pass. Congrats on being in the 11 second club.

There was a steady 10-15mph head wind everyone was down 1-2mph.

Man that's awesome, you need to clone that car. I've been following your build but missed what it weighs.

Look at the signature -- with just those mod's, 11.90's is not reality.....

And it runs fine? The calibrations for the LS2 TBs are very different from the LS3. Even the blade rotates in a different direction.

Also, the LS2 TB is a porters dream, tons of improvements can be had on the LS2 TB compared to any other GM TB.
