Im hoping some of our experienced drag racers here can help me out in choosing a tire here for the 1/4 mile and driving back/forth from the track (~20 miles each way)
This will be for my full weight 03 Mach (probably 3800ish w/ driver)
The car makes 715/580 on E85 at the moment
shift RPM will be 6800-7000
Wide Ratio Magnum Trans - 2.97 2.10 1.46 1.00 .74 .50
Rear end currently has 4.10s (rear had 4.56s when I bought, goal at the time was only high 500s/low 600s...) I realize this might have to change.
With the current stock rolling diameter setup (315/35/17) it looks like 4th gear would be a top speed of 130 according to tremec. Thats assuming the googled tire height of 25.68" is correct. My concern would be that if the loose nut behind the wheel ever gets his shit together the car would be capable or trapping more than that (correct me if Im wrong here...)
I havent bough new rear wheels yet, was going to look for something either 15 or 16" (preferably something that'll clear the cobra/bullett/mach stock rear brake setup with the use of a low profile banjo bolt).
How tall of a tire can I run? Suggestions on width? I know there are some guys running stupid fast on narrow tires but I havent made a pass in a stick shift car in nearly 10 years, Id rather have a little extra tire to help my ass out at the expense of a little more weight/rolling resistance.
Thanks for any input
