ok i asked in the general auto section.... no replys so ill ask in here. how can i tell what gear # i have... i got a set of aftermarket gears a while back and i forgot what they were... do i divide the # of teeth on the ring by the # on the pinon? i dont see any markings on the r&p so im lost

 

There is an equation for finding out top speed depending on tire size and gearing, can you do it backwards?

I think the equation is on the Racing Beat website.

 

Look on felixs site. It is in my sig. He has a chart there IIRC that gives tooth counts.

try that

 

It's easy, you divide the number of teeth on the ring by the number on the pinion. To work it out just put a mark on one of the teeth with a marker pen and start counting.

 

yep 11 & 43 so a 3.90 i was robed

 

isnt that stock?

 

Yep, 3.93 is stock.
