bolling

I have searched and not found what I am asking. What should be approximate top speed in each first second third and fourth gear respectively with stock gearing?
Thanks

1 = 54
2 = 80
3 = 118
4 = 148
5 = 210 if it pulled 7000 ram
I have the Rev limiter set higher so expect a little more from each if you put 7500 rpm

Pick your RPM's, use axle ratio of your choice (3.45) and these 1st (2.68), 2nd (2.80), 3rd (1.29), 4th (1.0), 5th (.75) and 6th (.50) - you can choose your tire as a 315/35/17 or use the actual rolling dimension if you would like to measure it. This will also show you RPM drop @ shift and the resultant RPM. I've done the math a few times and this is quite accurate "when you feed it correct information"!!

You need to understand that if your car is a '90 that you can't rely on the tachometer for accuracy. Actually you need to confirm tachometer accuracy vs. a scanner for all years before relying on it's display.

FYI: This chart is available from Marc Haibeck's web site with the understanding the tires are 315x35x17s:



And WVZR-1 is right (as usual!), far as using the analog tach goes. Even if it has been calibrated (not difficult DIY job) it is still subject to some lagging, especially when the rpm rate of change is greatest (i.e., lower gears especially). A digital scanner is one way to avoid mechanical tach lagging (or calibration) errors.

My owner's manual shows:

1= 40
2= 60
3= 80
4= 105
