Seems ok, Although my baja has a 1600 kombi box in it when on rally tyres for motorkhanas the motor often sees 5 000 rpm when sitting on a bout 110. ALthough this is with a subaru motor.

Waddya got for the front end? I was wondering if a split rear end would go OK on a beetle, is the gearing on CB's the same as big nut splits?

The engine might be working too hard as that is taller than standard - around 3200rpm for stock

It all depends on what sort of engine your running. If you have more power, then you can afford the taller gearing. Don't worry about the fan not turning fast enough, that's a bit of a myth.

At one stage I was running a 1916cc engine with an L-bug gearbox. With 31" tyres t gave a nice tall 4th gear. I drove from brisbane to canberra and back for the summernats with that combo. It was good on the highway. Offroad it was fine in the sand, but on really tight hilly dirt offroad some slightly lower gearing would have been nice. I later went to an 1800cc kombi gearbox with the same engine and didn't like the higher rpm on the highway, but the lower first was nice offroad.

Now I have a V6 engine and run a 2L kombi gearbox. It gives low gearing in first (not that the V6 needs it) and then I run an aftermarket 0.70:1 4th gear to make it sit at about 2200 on the highway. It's like a 5 speed gearbox with no 4th gear.

1600 kombi box with stock wheels sits on about 4000rpm at 100. your combo is just about right from what I know. My van with 225/60/15 with 2.0l bus box is doing 3000rpm at 100.
