I think you would absolutely gain some more whp from lighter wheels on the dyno.. less rotating mass. My 17lb flywheel netted me another 11whp and 8lb/ft tq.
I also read the oem nismo wheels were 21lbs F and 29lbs R.. if that's true then there's ~15-16lbs right there then whatever your new tires weigh, etc...
Relative to the baseline stock wheels the dyno results show the light weight wheels gained a peak power delta of +23.94 HP @ 4.2 seconds.
Relative to the baseline stock wheels the 20" heavy wheels lost 15.83 HP.
The max delta between the 17" and 20" wheels was 39.77 HP @ 4.2 seconds into the dyno run.

Exactly, but all the graphs show no gain in horsepower. Basically the entire article is double talking. Makes no sense. Says it gained whp but then the graph following shows no gain, only earlier peak relative to rpm.

remember that the area under the curve is more important than peak values! Getting up to peak hp sooner means more time spent making said power. Less rotational mass means a shorter climb to peak power.

But yeah, I don't see how it would INCREASE hp.
Sure understand it perfectly, but still doesn't correlate with a claim of gained horsepower.
It would increase whp because there wouldn't be as much drivetrain loss from weight.

Getting her ready for Willow Springs after a 6 year hiatus. Can't seem to find my HJC helmet though. Just waiting on the custom brackets to install everything.
$25 Hayden power steering cooler, one of the best cheap mods. Undetermined as to when I'm going just planned on sometime in 2014. Might go to the meet this Saturday, you?
Interesting. Also in during 2014 just lmk. No for me on Saturday, working at a music festival out in LA all weekend. Hopefully Waizzz will stop being a ***** and take more pictures haha
haha
