1.69 low gear
masracingtd1167:
What I am thinking is to change the rear from a 4.56 to a 4.71 and put in the 1.69 low I think this would help my first half numbers .
afuelcoupe:
thats not much of a starting line ratio change.......it takes you from an 8.02 to a 7.96 .........will help on the split though
what size and tire roll out are you using?
masracingtd1167:
I run the 12x31 Goodyears .
afuelcoupe:
thats only about 96 inch roll out .......is this an 1/8 mile set up or 1/4 set up? that is a very steep gear for 1/4 with only 96 inch roll out.....?what is RPM in the lights.I guess I would need to know alot more about your set up......
masracingtd1167:
I run 1/4 mile . Right now I am crossing around 9000 but I think that's where my motor wants to be . I have never dynoed it but I think it is a little shy of 800 hp . Last time out I ran some high 7.20's at 183 .At some point I would like to run 7.0 pro with it so I am looking for a little more !
