    A few have tried them around here. Lack of durability has been the biggest problem.Also loss of HP is a big negative.I havent looked up the numbers but I would expect to loose 20% engine power through the automatic.V8 engines can afford to loose some power 4cyl's. can't.

      Fun to try a C3

      I wish I had more time to experiment.

      A C3 has REALLY light internal parts but probably is strong enough as it came behind some V6s.

      It would be fun to set one up with a direct drive hub(no torque converter)behind one of our 2.5's.

      I think any serious racing automatic behind a 4 cyl would need to be direct drive due to rotating weight and inefficiency of a converter.
