I had my '79 5 speed out for a run today, and at an opportune occasion managed to wring its neck for a good distance. It accelerated very nicely up to 5700 rpm in 5th gear, what speed is that ? my speedo was around in the 230 to 240 area but I'm not sure I trust it. I know there is a graph in the rear of the owners handbook that gives speed / revs/ gear but. I havn't got it here.

Can someone help me out here.

Thanks, Cheers Roy

Roy, page 74 of the 78 owners manual has a chart showing speed/rpm for all gears. By my reckoning its 244kph at 5700rpm.

Thanks Hilton

I think there is more in it, I just need a lot of road to find it, we were covering ground quite quickly at that speed ! Acceleration was quite vivid till just over 5000 rpm in top and then tapered of to 5700, with a few more kilometers I'm sure it would creep beyond 6000 rpm.

I had an interesting moment overtaking a slower car on the way home, as I pulled out to pass, the back end lost traction and stepped out, at 120 kph in 4th gear. the road was a little damp and I think the line markings were quite slippery and as the rear tyres crossed them they made a break for freedom!

your tires will start to hydroplane about 60 to 75 KPH
be careful on damp or wet roads

So stay above those speeds, right?

Yes, your car will haul *** in ground effect.

I dunno, the speed limit around most turns here is 45, so the general rule is x2+5.
