This has been around a while, Ive used it before, but until today I had never scrolled past the crawl ratio table to the bottom of the page, at the bottom it tells you your rpms at a given speed. This seems to be very accurate and is all calculated for you. No brain power required
http://www.grimmjeeper.com/gears.html
This calculator will tell you the following:
All final drive ratios.
Crawl Speed at Given RPM in Feet Per Minute
Road Speed at Given RPM in Miles Per Hour
Road RPMs at Given Speed
There are options to factor in crawlers, axle gears, and tire size. He might add in a 3 tcase calc for anyone running triples.
And each table, except the final drive table, has scroll menus so you can change rpms and mph.
And the last thing is there are 2 columns so you can do side by side comparisons of different setups.
For anyone unfamiliar with this subject read on.
In step 1 you choose your tranny.
2.7 5spd = W59
3.4 5spd = R150F
2.7 and 3.4 autos got either the A340F or the A340E.
As Ive stated below all choices will produce a 2.57 t-case low so it shouldnt screw up the numbers too much if you pick the Toyota tranny.
One thing though, on step 2, there is only one Tacoma tranny listed A340F. This step determines your t-case ratio even though you are selecting your tranny again. So if you have a 95.5 and up Tacoma, 4runner or FJC choose the A340F tranny.
EDIT: A Toyota Tacoma and FJC option has been added. Choose that for your t-case ratio.
Xtra Info:
This guy is in the process of adding choices: W59 R150F and A340E to step 2. They will all produce the same 2.57 tcase low, but its nice just to get the details right.
As for you 6-speed guys I dont think he's gotten that far yet. im sure he'd be gald to add it in but he may need some help from ya'll to get it correct as I believe he's a Jeeper. But give him some slack he's created an outstanding calculator.
