Roll control and 2 stage limiter?

This is fine if you have a real light ride but anything with big power and 3,500+ lbs makes me nervous with a 727. A Th400 can take up to 4,000hp with the right parts.

That maybe true but I don't think that is what he has. Most race cars are in the 3000 lb range and not making 4000 hp. Mine is 2950 lbs and 662 hp.
