jw but what if someone just sold you a 3.3 and told you it was a 3.5......is there anyway of telling by looking at the pumpkin???

also when you cruise at 45mph is your RPM at 1800???

and another thing.......someone sold me there 3.5 gears on this forum and this is why i ask this question.....i installed the gears on and i believe my car did get quicker but my cruise controll still works while im goin 60mph on the highway.......also i only had the cruise controll on for maybe about like a min or 2 min.......i thought it doesnt work

im not saying that this person sold me something bad im just a lil confused

 

and since i already have them on how can i test it for sure that i have a 3.5???

 

Turn the output shaft/tire 1.00000000 turns and the input will turn 3.3 or 3.5 turns. Try 2.00000000 turns to increase resolution .............be accurate.

 

im new to this so i have no clue what you just said.....hahaha could you dumb it down for me

 

i think he meant: "Wtf are you talking about"

 

If you have the 3.3 diff, the wheels turn 1 time for every 3.3 times the transmission turns.

So if you turn one of the axles 360 degrees 3 times, the flange for the transmission would rotate a full 360 degrees 10 times with the 3.357. If you have the 3.538 it will turn 10.5 times.

Get some chalk, draw lines on the flanges, and have somebody else count how many times one part turns while you turn the other.

If you're all still confused, then you're just SOL.

 

ok i got it now thanks......i need to try this
