Speed at given RPM?

I don't have the fsm or anything handy since I'm at work.

I was out late one night and did a highway run. Just for fun and too see how she did at those rpms/speeds.

My speedo does have a low 20mph< wobble but smooths out. So I figure that my speedo isn't the greatest to read from.

I have 245x40x17 on the back so the stock ratio is very close. Under 1% variance I think.

So with the stock rearend in 5th gear in a TII tranny what's 6k rpm's equate to?

It said I was in the 135mph range. Did it with windows down and sunroof cracked too. :P

Oh yeah and for the speed bitchers. I don't need it. I know it is reckless and it's the first time I've done those speeds in a long time and I did it on a stretch with no one else there.

Just checked some online calculator.

With a 5th gear ratio of 0.762 @ 6krpm with 4.10 rearend and my tires it said I was doing 136.3 MPH.

I guess my speedo isn't off by that much after all.
