Default How about this gear/tire/converter?

Guys I am trying just about anything to get this damn car to 60ft and I need some input. What do you think about a 28" tire with 4.11's (in a moser 9") with a 3800-4000 Circle D 4c converter? So far the best is a 1.62 but I haven't really been able to run the car in good weather. Last time out it went 11.58 at 118mph with a 1.62 60', the weather was terrible it was actually raining on the top end of the track the last and best pass that I made.

I have Hal's in all four corners with a BMR extreme Trq. Arm and a drag bag on the right side.

I went out and tried it today launched around 1500 and it flashed to about 3700-3800. I'm thinking I need a little bigger converter

I can stand any converter for street driving thats no problem for me at all. I'm going for all performance. I have a converter from Circle D it's a 4c. It was made for his truck suppose to be 4000-4200 in his RCSB so I figured around 3800 in my car, but I could be way off. The only thing I'm stuck on is that I want to get the car as fast as I can NA and spray a 100-150 shot. I was thinking about a 4200 or so?

Correct the 4C is about a 3600-3800 in your setup. Might need to step up to a 5C. Which would be a bout a 4200. We can do a stall change on yours in just a few days. PM me and we can get something going.

5k stall with a trans brake will help your 60ft . with my 3600 stall i would do 1.63 60's at 117, with the ati 5k stall the best was 1.48 at 121mph with the 2 step at 4500. the track would not hold more then that with the tires i had (275/40r17 M/T).
