your going to need less gear with a th400 for the 1/2 mile. unless you don't care about pushing your motor past 10k. lol.

with a 28inch tire, 3.25 gear, at 7500 topped out will be at about 175.

At 8000 will be about 186.

If i hit anywhere around 180 ill be happy.



A 3.50 or 3.70 gear is a lot for a 88mm turbo pushrod car. What RPM are you planning to spin the motor to?

*edit* What size tire are you using?

28inch tire

7500-8000 rpm

problem is your going to hit that rpm way before the 1/2 mile ends, no?

that combo should EASILY trap in the mid 150's in the quarter even with that 3.25 gear. now add another 1320ft to the equation.


i have never done a 1/2 mile event. it just seems to me unless you roll out a good amount before you lean into it, your going to be in a very high rpm band very quickly.

I agree completely. If it happens to run out of gear then ill have to live with it. I don't really want to spend extra money for one event since the car will mostly see the 1/4 mile anyways. I will go out there and put it to the wood and hope it goes home in one piece. Lol
