Thread: Looking at buying and racing this old dragster.

Pro comp if I remember from a few years back is a 7.90 bracket class. My dragster was a 225" S&W chassis. It was a pro comp when I got it. I pulled the alky set up and switched to 112 race fuel to slow it up some, backed off on the throttle stop and It was then a super comp 8.90 class dragster. The class change cut about 800- 900 rpm off the motor at the stripe, and was an easier car to drive. Much easier on parts and semi affordable to run.

About a gallon of fuel per run, 7.70 a gallon, thats driving it to the line, doing burnout, making pass, and driving back to the pits. and after each race DAY it got a 9 quart 10w50 oil change and filter. And then a once over on checking for loose fasteners and fluids, drain the puke tanks before the next big day. Just because the chassis is certified to run 7.90 does not mean you have to run it in that class. it just means thats the fastest class you can run it in. You can slow it down and run in other classes also. also running an 8.90 class requires a full length fire suit, a nomex liner in helmet, and arm restraints, at least it did about 5 years ago.
