my feelings are hurt lol

 

thats cause gearing will always affect torque, and hp is only a mathematical equation of torque


and i wanna see this race!

 

hehe I heard you got something on your car now.....

 

Sorry guys, but you're wrong. Speed is a product of gearing and engine rpm. No matter what other factors are involved, the vehicle cannot go different speeds at the same rpm in the same gear. That would require the vehicle to somehow miraculously defy the laws of physics, which, to the best of my knowledge, cannot be done. Whether a car is capable of achieving said speed on the street vs. on the dyno is a different debate, which we'll save for when the time is right.

 

Exceptions: spinning tires and varied tire circumfrence. No traction means that the car is not moving forward at the predicted rate of tire rotation at a given rpm and gear. Changing the tire height (and therefore the circumfrence) would also alter the distance travelled for the same tire rotation using a different tire size at a given rpm and gear. I'm a nerd. Don't hate.

 

lol, Rich, half these guys can barely comprehend 2 + 2 = 4, muchless dynamics. Tryin to keep it simple for them.

 

Thank you.

 

its nothing special, not even worth talking about.

 

All this is true...unless we move from manual transmissions to automatic transmissions. When doing this one would also have to take into account any converter slippage that may occur under a load which could cause rpm and mph to be off when comparing street and dynojet numbers.

 

That would take one HELL of a loose converter. I dyno'd my old car with 4 different converters in it ranging from a 2400 rpm stall converter up to 3500 rpm and none of them reached any higher speeds before hitting the fuel shutoff on the dyno than they did on the track/street.

At any rate, point being, those of you trying to argue that the vehicle will be doing a different speed at a the same rpm between being on the dyno and being on the street are trying to defy mathematically proven formulas.
