What kind of gear in the dragster? A 1.08 60' should be better than a 5.05.

4.10 gear. Its was the first time out we had 37 nozzles in the terminator and a 85 pill. The car was making heat even on the return road. I think we were a little lean. I have a 535ci with 4 1/2 stroke crank and the converter stalls 6200, may be some of the good 60ft. We're going to richen a little and move the timing up to 37-38 from 34. I'm expecting to go a little quicker. The dragster came with 34.5x17x16 slicks a 110" rollout. I ordered a set of Hoosier 33.5x17x16 with a 106" rollout. The altitude density was 5400ft with a 20mph crosswind. I'll get to see if any of these changes will help in a week or so.

We run a 4.30 gear in our 4-link Mullis. We run gasoline and have a 1.07 60' and run 4.70's. We had the 34.5's on our car and they would shake it to pieces. We went to the 33.5-17-16 Hoosiers and they are a lot better.

I ordered a set of 33.5-17-16 Hoosiers and they have 110 1/2 written on them. I set them next to a set of unmounted 34.5-17-16 and they look identical. I called Hoosier and they said the air the tire up to 20psi then check the circumference of the tire. I'm thinking they may be smaller than that at 5 psi, but I'm doubtful it will make 4 1/2 inch difference. They advertise 106" rollout. I guess I'll send them back. That part # is 18700 Hoosier, I'm thinking about ordering #18500 which is 33-17-16 with a supposed rollout of 104". I really think I need to get a shorter tire with the 4:10 gear.

We run the 33.5-17-16 CO7 and I like it a lot better than the 34.5-17-16.

Love the humor parker. Any luck moving the truck?
Sorry Beast, I just now saw your post. Yes, I traded it for a PSP 4link x-braced mono-shocked dragster. Car seems to work great. I'm going to try some new tires this weekend. Still miss the truck, I guess we'll find out if those wins were the truck or me. It sure is a different feeling. In the truck I just wanted to go rounds. Now I'm entering quick 8s since I can qualify. But when you running two different classes at the same race I don't know if your as focused as you are just running one class. Guess we'll see how this year goes.
Thanks for the interest Beast
