as for times, that all depends on what cam, who's heads and any free-flowing intake will do. Besides, the only real upgrade for intake is the LT4 w/ LT4 style heads. And that isn't much of an upgrade as per an LS1 going from stock 78mm to a FAST 90/90. |
Really? I have an A4 97 Formula and I run a 13.2 w/o "full bolt ons" that's enough to beat most stock LS1's, A4 AND M6. I have no problem beating LS1's.
