What I'm trying to decide is a rear end gear change for my home track of Thunderhill. The 3.43 is just too low. I'm coming out of thrn 11 in 3rd at RPMs as low as 3200. At the end of the straight I'm at about 122-4 MPH in 4th. I think a 3.90 would be about right for the top end but I'd like to see how the 3.90 would work coming out of the slower turns.
