I've read the millions of threads stating the 400-450 RWHP limit of the W58. Then there are some people making 5-600 hp semi reliably with the W58. Most of the W58's that blow are street driven, full weight, launched and hard shifted.
Does anyone have experience with a fully gutted car in the 3200lb range that road races exclusively? I figure the W58 wouldn't last long with race slicks, but may make it on street tires.
I also read that a completely NA race car was stripping the input shaft continually.
Is it worth $3-500 for a clutch to test out the horsepower limitations or should I spend $2,000 on an R-154?
