It's a Hurricane Motorsports Cobra with a 347 cu in. 500 hp - fastest time yet is 11.3 secs at 121 mph. Tire pressure is equal on rear tires(and front). Has adjustable QA1 shock system which has been weighed and setup for road racing. I adjust the shock knobs one way(softer) for drag racing and the other way(harder) for road racing. Right now it's set up for drag, so the shock knobs are adjust to 5 on the passenger side and 3 on the drivers side. This setting is supposed to help keep the rear of the car level during launch. And this is the setting that I need to run straight, instead of going to the left at burnout. I'm thinking that adjusting the panhard bar may solve the problem. Also, maybe the trailing arms(or track bars) are not adjusted equally in length, and are "kicking" the axle off at a slight angle. Thanks for the advice so far. Tuesday, I'll be calling the factory for advice and talking to a couple of mechanics with drag racing experience. Thanks for all the tips, and I'd like to get more advice from anyone who has experience on this matter. I've been studying up on the internet, but I feel like I'm missing something...
