do i divide the pinion into the ring gear to get my ratio? 35 on the ring and 9 on the pinion 3.8888888? do i have a 3.80 and how much better would that be compared to my 3.50 thanks john trying to get a better 1/4 mile time and i have this set of gears i could put in.
From a 3.80 to a 3.50 is insignificant enough to be acheived through tires alone, not gonna change quarter mile significantly
3.888 rounds UP to 3.90's. And yes, they will give you better 1/4 mile accelleration, provided you have enough traction to use the extra ratio.
i think i can put it to the ground with my hoosier quik times it bit pretty good at the track the last time i was there but i ran out of gear at the end of the 1/4 was only turning 4800 rpm and my cam is good to 6200 rpm
john, play with the calculator at the bottom of this page. http://www.chrismans.com/Calculators.html this page is has some fun ones to play with also http://users.erols.com/srweiss/index.html
The 3.90's are going to still put you short of 6200 rpms. 4800 will change to 5348. If it's a street/highway driven car, then you don't want more gear than 3.90's. If it's a strip only, then you may want to go as high as 4.30's, again, provided you have the traction to take advantage of the extra ratio.
