FWB, good point about the trap speed. While my ET remained fairly consistent my TRAP SPEED was notably slower. The big horse power really shows itself at the top end, some where after you've gained enough traction to use it.
I dang near lost the car when the tires broke loose in 2nd gear, I was running Goodyear Bill Boards which have "decent" traction for a street application and not bad for a race application. They are going to be hard to beat when it comes to traction unless you move up to slicks.
