Default New goal...

My new power goal will be whatever the traction limit in 4th is on the best rubber I can find.

On the 335 series R1's on the car now, the tires go up at about 630rwhp/680ft-lbs according to the logger. I'm basing this on mass-air meter readings, as well as good old physics...I know the weight, and speed vs time, the car has the equivalent of a flight recorder on board that stores everything.

My car is a 96" wheel base car with a non-parallel 4-link, and is within 20lbs on all 4 corners with me sitting in the drivers seat. It's also on the heavy side, about 3000lbs with driver and a full tank of fuel. If you weigh less, and have less tire, you'll likely break traction sooner. I have my throttle stop set at the traction limit currently, and aside for not having much throttle travel to work with, the car is a lot more fun with its balls shrunken.

I'm not going to get much more tire on here. If the traction doesn't improve, the new goal will be right around 600. I want a car I can control on corner exit in 3rd, and WOT on the straights at speed without having to work so hard and/or roll the dice so often. When I go to the straight track, sure...that's a new game with different tires.

So, at the run & gun, would they let a car like mine run in the 10's or better with my single 3" bar? If not, there's no way I'd make the haul out there to compete. I'd rather just get kicked off the local drag tracks, have my fun on the road race course, and and call it a day. I already got a rejection from Hot Rods Pump Gas Drags. "We'd love to see a Cobra out here, but you need an NHRA legal cage in the car." I'm not doing that, I don't care enough.
