Well, a 35hp loss out of 300bhp is 12%, out of 250bhp is 14%, out of 200bhp is 18%, etc. etc... from what I've read from engine builders, the power loss through a typical manual tranny correlates more closely to a fixed hp number rather than a percentage of flywheel output. Otherwise, a 700bhp engine with a "15% loss" would be losing 105hp, which apparently doesn't typically happen. The percentages just work as good approximations within the 200-300hp range that most people are in...

Other mustangs with engines set up similar to mine usually make in the neighborhood of 230rwhp.
