Lightweight wheel difference!

[mustang87]

The wheels are $12,000 though.......

$/HP gain not worth it IMHO.

That's my point, not even close. There's so much more you could buy for that kind of money. Nothing but bragging rights IMO.

Motor Trend did a comparison of a GT350 and GT350R (lighter weight wheels on the R)

The GT350 put down 467 hp / 374 torque, the R 471 hp / 376 torque.

So essentially equal within the dynos margin of error and slight production variances.

I wouldn't say that. Any error or production variances, could have actually swung in favor of the GT350R.

It's just math that lighter wheels/tires = less rotational mass = more power to the ground. It's also gets there quicker too.

You also have to keep in mind the GT350R is a track built ready car so its different then your average S550 or the GT350 which is still track and street, but the R is literally a street legal race car, minus the roll cage, fire extinguisher, full race team and sponsors lol

I'm not arguing that lighter wheels aren't better.

Just that those dyno numbers are so close together that if you used two different cars that the numbers might turnout the other way. Back to back runs of the same car can change more than 4hp and 2 tq.

of course but thats why you run them multiple times and average it, am I wrong on that?

It would of been more accurate to Dyno one of the cars then swap wheels.

Has anyone done any dyno or track comparison between a GTPP wheel and lighter wheel? I would like to know dropping 40+ lbs rotational mass is worth it or not. Thanks guys!

:doh:
