With a stock tranny, and engine, you can run up pretty close to 65mph in third, and cruise in fourth. Our 4th IS an overdrive. With a stock engine, everything is pretty well matched, torque to rpm to mph. Now when you start pumping the engine up to like a 2.0 liter, (like Toby), that is a different story. Our stock engines are pretty much limited to RPM, by their breathing ability. Air in exhaust out. This is where the old stories come from that you can drive a VW "Flat on the floor all day long and not hurt it" comes from. This was from the old 36hp days when the engine was choked by an intake manifold that was probably less tha 1" in diameter and real long. It couldn't take in enough air to hurt itself. As displacement and fuel systems improved, that idea actually went away as far as the mechanics were concerned. "Yeah, let people drive that way, it is more money in our pockets repairing them." All I am sying on the porsche tranny swap, is it worth the effort, for the gains you would receive. Besides, the person asking has a '67, which means a complete rear subframe swap to do it. > > I've heard good things about the 901 trans.

And that one on Ebay is of that vintage. They were a fragile trans, if abused. We would road test every Porsche as it was unloaded off the transport for tranny problems. We would not accept them until we did. We found too many that were just damaged in transport from Germany, and then we had to fight with Porsche for the warranty claim after we took delivery at the dealer. It was kind of fun road testing 911 turbo Carrera's ;=) -- Russ Wolfe '66 FB MT '71 FB AT '65 Bug (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
