I-Dom-In-8 - have you done this mod yet? No? Well then listen to someone who has. It makes a BIG difference in how the car drives. More HP and an earlier opening throttle. I know that the manifold is not as large as the TB (hence the reason I added the SVT manifold later) BUT the stock TB is smaller than the hole in the stock manifold. Don't forget about the area that the butterfly takes up...
Unfortunatly I did not dyno this mod seperatly from other mods I did, but on the butt dyno the TB and the SVT upper manifold were the two best mods yet...
