Need some help here guys! Were sending in my sons car next week for the May race, but wanted to correct what I'm thinking is an alignment problem. His car won district, but certainly not by average times! It would run once or twice in the 2.90-2.91 range, then the next run or two it would run a 3.05 and even got as slow as a 3.11 ! When it was on it slow runs it made a funny sound as it went down the track, almost like the high pitched sound a drill makes when its slipping off a screw head (bad example, all I could think of). When it would run fast, it just hissed down the track.
The car has 1 gram wheels, 3-wheeler, tungsten weight, com at about 3/4 inch and pulls about 1" to 2" in 8 feet. I just recently noticed the raised wheel is turned in, as if to turn the car into the rail. I didnt see any nicks in the raised wheel, but its a 42' best track so its pretty smooth anyway.
Do you think its not pulling into the rail hard enough, bouncing off and the high pitch noise was the raised wheel riding the rail? I have since straightened the raised wheel as best I could, but since the car was so fast I'm afraid to turn it into the rail anymore? Is 2" enuf?
Any advice would be appreciated!

Miller, I had the same issue with my Stocker when I first put the wheel and axles on. One run was fast, the next I'd hear a high pitched squeal and the times would drop. I found that my rear left wheel was scrubbing the rail sometimes. I work on the rear wheel alignment and got it straight. Now she run run smooth quiet and fast. I would start with the rear wheels first.

So was the rear wheel draggin on the same side as your steering wheel or raised wheel? I'm kinda up a creek cuz the wheels are glued in with about 7 gallons of epoxy, so trying to remove the wheels would be impossible.
We originally had intended to just run the car in the pack races, not pddr, so we didnt plan on ever removin the wheels!

Same side as the raised wheel.
