Feature Race Win

Yesterday was the 2nd of 9 points races. It was one of our two feature races with Jet Cars, Nitro Harleys and some AA/Fuel Altereds. The weather was nice (bad air though), no oil downs and the features put on a good show.

The car ran pretty consistanly in the 12.10-12.20 range in qualifying. The weather was moving around with the DA north of 4000'. I ran 2 classes; Sportsman and Street. Went out in the 2nd round of SM on a double breakout to last year's runner up. Won the Street class with a pretty good package in the final 12.033 on a 12.03 with an .022 light. Should have a healthy lead in the points there with 2 wins in 2 events. Not doing so well in Sportsman yet though. Hopefully make a better showing next race weekend in 2 weeks.

On another bright note, I think this was the last race weekend on the stock 3.08 geared 7.5" rear end. My 35 spline, aluminum ceter sectioned, 3.89 geared, Detroit Locker Moser 9-inch has arrived!

Re: Feature Race Win

congrats on the win, im assuming the sportsman class is some pretty stiff competition. Glad the 10 bolt has held up this long. Do you think the 9" will slow you down? or will the 3.89 gears compensate enough? what are you trapping rpm wise with the 373s?

Yes there are lots of tough vetrans in Sportsman. I raced both classes last year. I finished 4th in Sportsman and 2nd in Street. I broke one 10 bolt last year with 3.73s. Best pass was in sig. Best 60' was 1.63. I put in a 3.08 geared rear to tide me over and went 1.67, 11.84@114.8 with that combo. Both times no 235.60.15 ET Street Radials. Trap RPM was 5800ish and 5200ish respectively. The converter seems to slip alot more with the 3.08s (unless it has just really loosened). I am going to try 28x11.50 ET Streets now.

How does your track define "Sportsman" and "Street"?

Re: Feature Race Win

Sportsman cars are limited to 11.50 dial ins, no tbrake, and no electronics. Street Legal cars require insurance and DOT tires but anything else goes.

Re: Feature Race Win

Nah, the Sportsman class has all fo the vetrans in it and some very well built cars. DOT here includes ET Streets and the like. I have been running the raidla version but I am going to try another set of bias-plys with the new rear.
