Howdy,

Trying to compare different upgrade paths. And comparing HP numbers always brings up the crank vs. wheel hp. I'm sure several forum members have run a dyno on stock to get a strong understanding of their starting point. Can anyone provide those results?

For example, Toyota says we get 385 peak break horsepower. Everyone that dynos the stock car gets about (big average here) 350 at the wheel. That'd be about 10%. That'd be light for a automatic and rear wheel drive.

Search YouTube, there are a few out there. From what I’ve seen the 20s had about 340 to the wheel and the 21s and 22s have about 385. All dynos will vary but from what I’ve seen BMW typically underrates their HP numbers a bit.

Interesting.

So the take away is the only wheel hp to wheel hp claims are comparable. Short of pulling the engine and testing on an engine dyno :) Any brake or crank horsepower claims have to simply be ignored. Ok.

Nice to see we get more than we paid for :)
