I'm running a old D15B2 delta regrind in a Z6 block B7 head combo with the cam in the advance position. It has a Chinese T3/T4 @ 15psi, B7 intake manifold, Si tranny, no bov, Cast ex manifold, tuned on BRE on E85. Finally hit 12s on drag radials with the stock block. The question I'm debating now is if there's more room for improvement in the cam side if things. Been trying to find a A6 cam online with no luck and from what I read the Y7/Y8 can gear should correct the cam timing. I'm wondering if I should just leave the set up as is or try to correct the cam timing situation. Here's the dyno graph at 12 psi to show how the curve is. And the time slip with car weighing in at 2105 pounds. Also wanted to throw in that removing the sway bar reduced wheel hop and allowed me launch more aggressively. Still on stock suspension so it might not have as much effect on a stiffer set up.
