Default Dyno after changing wheels.

I was just wondering... was thinking about this last night when I was driving around.

If you change your wheels from the stockers to an aftermarket setup that is say 10 lbs lighter on each wheel, do you think the HP to the wheels will go up significantly? Cause if you think about it, the rotating inertia of the wheel is reduced greatly, which uses less energy from the motor to make them spin.

Just a thought.

Dude i was watching videos of you racing on the highway and your a total loser. I hope a cop pulls you over someday and gives you a huge ticket. Driving fast and wreckless on the highway is stupid just like you. You could wreck and kill an entire family. I live in jersey and if i ever see you ill break your skinny neck you flamer! P.S. Lighter wheels wont make your horsepower go up, your soo stupid you know nothing about cars you should kill your self right now for being a worthless human.

Ummm yes it will.

To the OP, yes it will make a difference, how much I do not know. Going from something heavy like the AP2 OEMs to a light wheel like the SW88s or Slipstreams for instance will significantly reduce the resistance in the drivetrain allowing more power to make it to the wheels.

Wow, someone's butthurt. Anyway as said above, while your horsepower won't "technically" go up, more of it will make it from the motor to the wheels. The power is always being made by the engine, but as you lighten things, reduce backpressure, increase mechacnical advantage, the dyno will show an increase.

for the hater

yes your dyno will read higher with lighter wheels. i think something like every pound of unsprung weight equals 4 pounds? don't quote me. but yea, buy my wheels.

back to topic,

andre i think it would result in a lower loss factor, which would effectively give you more power to the wheels due to less rotational inertia. It makes sense to me anyway

at the end of the day, lw wheels = faster

Oh yeah... I know the engine power won't go up, but the power to the wheels will go up, which is what really matters.

My question was more along the lines of how much more it could possibly make... just a curiousity and topic of convo... lol.
