My Spyder has a 200hp Suby engine. Tranny is type 1 4 speed with 3.88 and an LSD. Geared low. 4000 rpms at 70 in 4th. I like it geared low. Never get on the highway. Danny says I don’t need the LSD but with such a powerful engine I think I’ll keep it.
Obviously I’m building a very powerful Type 4 for my speedster. This car will be used more as a cruiser and highway car and rarely driven in anger. Using a 3.44 R&P with gearing similar to what Danny described. No LSD. Greg has promised me 70 in 4th closer to 3000 rpms. With an air cooled you need some rpm just to keep the engine cool. It will be fine.
