Agreed. I ran the 3.55 and am now running the 3.31 and very happy. I have plenty of power thus losing some low end torque has not been an issue, and it is very nice having the upper end range and increased top speeds.Opposite, im considering going to a 3.55 instead of the 3.73 since im running a lower gearing tire of 285/35/18. Id like to go through the traps not on the limiter if i can help it.
I would be more concerned with the gearing of your rear tire in conjunction with your gear ratio and expected trap speeds.I understand I just have always been around drag racing since high school driving my 70 mustang. Just want a little wisdom from some guys who do it in there Boss. I know that 99 percent of the guys on here road race I just never had no one to teach me. (No tracks near me) I have a quarter mile strip 10 miles from me plus racing every weekend. So that’s the route I’m want to take with my Boss.
The fast guys around here in 4 cam fords are running 4.56 at the drags, the blower guys are running 3.90s, My gt500 went went 12.64 with 3.31s.
I'm thinking a 3.90 to 4.10 would be fine for 90% of the road courses out there with a normally aspirated car.
What mph do you trap right now and what gear/rpm when you cross the line?
This.
When I was drag racing we always tried to gear for crossing the line around peak HP rpm in a 1:1 gear.
