For all of you that are always asking the gear question:

Website that will give you RPM@Speed w/ certian gear set:

Website that will calculate rear tire diameter (so you can input it into the above calc)

Pretty cool.. the info is appreciated

Thanks for post this. That is very useful and i will use it alot in the future.

 

really apricate you posting that ,, really an formative site just have to decide 3.27 for better gas or 3.55s for power,,?? i take alot of road trips but i dont like the 2.73 ..power wise.. but gas wise its great... which choice would be the best?

 

Now what we need is one that incorporates the gas $ with gears at certain speeds!

But I still love my 4:10s to death....

 

diameter website isnt workin, anybody know the formula

 

acually if anyone wants to know any of this info at quick hand...just have one of you get me the formula and the different things like that and i will make a program that does it all...just get me the formula...

 

Here are some formulas for you to start with:

mph = (rpm x tire diameter) / (gear ratio x 336)

rpm = (mph x gear ratio x 336) / tire daimeter

gear ratio = (rpm x tire diameter) / (mph x 336)

tire diameter = (mph x gear ratio x 336) / rpm

 

If there any others you might want, just let me know...I have several others that might interest some people.

 

lol sry it took a while..i havn't been on the forum for a while but i have these now so it should be here like tomorrow or friday
