which is a very tall gear for 1/8mi, 4.11's are a mild gear for 1/4mi cars. i run 4.56's in my 1/4mi car and still have about 500rpm to go when i hit the traps at about 6200 and 122-124mph.
idealy you want to be running through the traps in your final gear at just about your top rpm. right now he is running through the traps with 4.11's, 28" tall tires, and at 79-80mph at 3900rpm. this is way to low, there is still a whole lot to be had out of that engine that is not being used on the top end of the track. idealy about a 5.39:1 gear would put him through the traps at around 85mph and at 5500rpm with the 28" tall tires.
1/8mi is a different beast than 1/4mi
