yeah, we don't put a TON to the ground stock- however another thing to look at is the curve on that 230AWHP.
A bone stock 93 Cobra could put like 215 to the wheels, in a lighter car and still the best I've ever heard is 14.1
An LT1 Z28 had 275 rated, like 230 to the wheels, and rarely if ever broke into the 13's bone stock.
We use EVERY drop of power we can, and it seems to still defy a little physics from time to time
Now- a BC- suddenly you are looking at like 280+ to the wheels... nice little jump
