[TR] TR3 speed Vs RPM

[davehogye]

Frank, 
I'd say there is a 4.1:1 ring and pinion in the car. My TR3 has similar revs with the 4.10.

A TR3 with the stock size tires and 3.7 rear end ratio, 3000 RPM was 
60 MPH. Unless your gauges have been rebuilt and calibrated, They usually 
read high. The springs in them get weak.

have been unable to drive my car for a couple months now. 
when i bought my TR3 i did the restoration and put a toyota 5 speed in. 
so i have no experience to go on. not untill i can drive my TR3 again. 

took a friends TR3 for a ride last night. 
we hit 75mph, but the rev's where at 4500 to 5000 depending on coast or maintain speed. 4th gear, no overdrive. 
is this about what the rest of you TR3 owners experience? 


also it has always been my experience that if one gets wheel wobble between 55 and 60, its wheel balance. 
slower than 55 is ok, accelerating beyond 60 makes it go away. 
no? 

thanks
