I honestly don't know

brake horsepower

[RandomGuy]

brake horsepower

or wheel hp

[HvyArms]

or wheel hp

is there a diff between, engine hp and wheel hp?

yea, whp is what you actually put to the ground on a dyno, its always gonna be less than what the actual engine has

ahhhh, okay that makes sense.

You loose horsepower thru the drivetrain. It takes horse power to turn your tranny, wheels, axles, etc.

[TeeJay]

Yes in a since...because when you look at stats on like MSN cars and stuff like that they list the engine HP which is how much it puts to the fly wheel?(not sure if my termage is right) and then wheel HP is how much actually makes it to the wheels...

For example my car, they say has 175 HP, but only about 160 of that 175 makes it to the wheels. so my HP is 175, but my WHP or FWHP is only 160...

i think it would actuall be more like 150 or 145 lol, its a pretty big drop

Right, okay. So you lose power through the drivetrain then. Is it pretty standard from car to car, as far as the amount you lose? And, what are some of the best ways to prevent the loss in hp?

dunno about from car to car, but ways to prevent it are to remove anything that causes stress on the motor, ie...power steering, ac, cruise control, etc

[HvyArms]

Man, it's sad. I don't crap about cars. I do know, that my car supposedly has all this HP, but sometimes it doesn't seem like it reaches the wheels.

Lighter components such as flywheel, clutch, driveshaft, wheels, rotors, basically whatever stands in the way of the power getting to the wheels will reduce loss.

For instance I went with a lightweight clutch and flywheel on my Infiniti G35, the car is rated at 280hp measured at the flywheel but actually put down around 222hp to the wheels with the stock clutch and flywheel. After going with an Clutch/Flywheel assembly that was roughly 30lbs lighter the car put down around 238hp to the wheels.. it didnt add any horsepower, it just reduced the loss of horsepower through the drivetrain and greatly improved engine response. The downside was it was hard as hell to drive daily.

As it pertained to G35's, automatics see more drivetrain loss than manuals but I'm not sure about other vehicles. Hope this helped.

why was it harder to drive?
