I bought my car used so I do not know what upgraded gears are in it, if any at all. I was reading the 4.10 thread yesterday and noticed someone saying they run 2g@60mph. I paid attention to my tach yesterday and mine was right at 2g or a little under @60mph. Got up to about 70 or 80 and it was around 3g or a little less. I will have to double check on that one. I am new to sport cars so I am still learning. Does it sound like the guy upgraded before I bought it? If so what gear setup does it sound like or how can I find out?

 

Here is a gear calc. Go and do lets say 60 or 70mph and right down the rpms or remember them then go here plug them in and you will find what rear gears you got. Enjoy.

Ok I can't get that calculator to do anything. I checked again today and at 70mph my rpm's are @21 and at 60 mph then are @19..Any other help or guesses at what they are?

 

stock 3.27 gears are in your car.

 

That's what I figured but just wanted to make sure before I bought new gears. Thanks man.

 

yeah I couldn't get the calculator to work either....does anyone know what the RPM's would be at 75mph with 3.73 gears on a 5 speed?

 

it works just fine i have used it a few times. just add the gear number and mph and it tells rpms etc.... easy to use.
