Thread: Best gear for 1/4 mile

Tweet

$.56 to 5.13 i,d say for an average bracket car. I ran a 391 with 26 in. tall slicks ant car ran consistent 12s Changed to 4.57s and ran out of motor in last 200 feet and had to pedal. no better time . channged to 30 in. slicks and put car in high 11s Sometimes gear changes work better with a specific tire size . If you use 2 much gear you can compensate with taller tires if you have enough convertor to stay in your power in the 60 ft.

Im running the 4:57 gears with 33" tires. When i cross the line im turning at 6300 RPM. When i drop back down to my 32" tires, I was crossing the line at 6700 RPM. The only time i use the 32" tires is if i know the track is really going to hook up hard, the smaller tire gives me a better hole shot. ( 2 speed powerglide) My engine will still pull at that RPM, But i just prefer to keep the RPM's down to help save engine.

i make power all the way to 7200 and i am going through the lights at 62-6500 which is why i am going to my 5:13's with the 29 tall tire. right now its 4:88's

When you run a tiny little motor, you need really big gears . . .

Like my little 283?LOL, guess it depends on if you want to go on the hwy too. my 4 speed with 3.70 gear winds all the way out in 3rd gear 26.4 tire and for the hwy I still got 4th gear. If I kept it off the hwy I could go 4.56 and wind 4th out in the quarter.
