My Son is building up a '68 Porsche (wait, it really is a Hotrod!), and will be installing his 450HP Rotary Racing Engine in it. (No Pistons but somewhat limitless RPM/HP with enough Fuel and Air).
The stock Porsche 901 Transaxle, similar to a big VW Trans but beefier, is good up to about 250 HP. The Rotary Engine will hang off the Trans back, just as a stock Porsche/VW. He needs to replace this Transaxle with something a lot stronger. He mostly drag races. He's looking at a $8K custom Porsche trans but, as the Dad, I'd like him to consider other options, if there are any.
Corvairs, VW Bus, etc can't pull the HP. I haven't found any Front Wheel Drive, 4/5 Speed Transaxles that are strong enough. Any ideas on this. Has to keep the Engine in the rear so a Ford 9" is not in the cards. It can't be a Torando since he wants Manual Gears.
