I made a 1/2 inch throttle body spacer and installed it on my car. The car reacts differently from 2k to 3.5k. More torque. As for runner length on our stock cars. the rummer length is just fine the problem is the restricted runner size. they dont have good flow dynamics. DID any one read the manifold comparison In the HCI magazine? They made a manifold with the same runner lengths as a bone stock 2001, but increased the tube size. With increasing the tube volume they gained 14hp near redline compaired to a stock mani. that same manifold under boost it gained 35hp compaired to a stock 2001 under boost.
so they concluded that our motors like the long runners, they just need more volume. this info is in the DECEMBER 2002 issue. good stuff.
im goin to try a 1 inch spacer tonight.
