Curious about HP loss through the drivetrain.

HP varies quite a bit depending on elevation, air temp and atmospherics. Also ignore all the dyno numbers from aftermarket parts mfg companies who freely rig the results because they are also quite variable.

Chasing dyno numbers from others is like herding cats. An exercise in futility. The only ones that really count are on your car.

Exactly why I picked that Fabspeed video. Figured they would post as low as possible on the stock HP number, which they showed 229 whp. That's about a 11% loss from Porsche's 258 bhp number.

I thought that was actually pretty good, then Jake rained on my parade lol. Maybe that's what j.fro was referring to as I'm sure Jake's engines were producing more then 258 bhp.

Chasing others dyno numbers is a fools errand.

I'm not chasing anyone's dyno numbers. I'm trying to find out the percent of HP lost in the drivetrain.

So a 2003 Boxster S has 280 bhp?
