Dave,
Using the owner's manual data of 482 RPM @ 10 MPH (Carb/USA Market TR6) and
multiplying that times 6.5, we get an RPM @ 65 MPH of 3133. However, before
I would start tearing into the rearend. I would consider two other
possibilities: 1.Is the speedo reading correctly? 2. Is the Tach reading
correctly?. Checking the speedo is easy, just get a friend with a modern
car, and have then drive next to you @ 65 (on the freeway). Is your speedo
also indicates 65, then your speedo is OK.
Hope this helps,
Hugh Barber

Subject: RPMs WAY too high !
Ok, its a nice day out. So I took her for a ride. Remember: my 1969 TR6
4-speed manual transmission, first time on the road in 17 years? Today I
drove several times at an indicated 65 MPH on the speedometer and the
tachometer indicated 3650 RPM !!!!!! Help. Too high. What does this
mean??? Do I have a 4.10 rear? Did the previous owner change it maybe?
Could it have been ordered this way? Or should I just disconnect both the
speedometer and tachometer and drive it without either of them, that way
I'll never know better (that's what I did 18 years ago, when I was last
driving it).
Sincerely,
Dave Herbert
1969 TR6 and nothing else
