I was curious to know if there is a conversion from flywheel horsepower to wheel horsepower? I've heard that stock 2.0L Tibs have ~100 FWHP...meaning about a 29% loss within the drivetrain.



Is it a standard conversion or does it depend on gear ratios, engines, and driving axle? thanks

 

There is no standard percentage. Its going to be different for every car. And I believe the 100 WHP was for an auto if I remember.

 

Flywheel horsepower can be estimated from measured wheel horsepower but it is just a loose estimate. Usually 16-17% more than measured wheel horsepower is a good estimate for a manual transmission front wheel drive car.



Flywheel horsepower is always MORE than wheel horsepower, so a car with 100fwhp would be more like 85whp. A car with 100whp would be more like 117fwhp.

 

I know back in the day when i had my last tib most people were dyno'ing at 117 whp on a stock tib.. idk what itll be nowdays since most of the tibs have more miles on them but yeah
