would a NPC one work? https://www.npcperformance.com.au/product/lightweight-billet-steel-flywheel-rnf03/ and here's their catalogue: https://www.npcperformance.com.au/wp-content/uploads/2024/03/NPC-Performance-Flywheel-Catalogue-2023-Full-List-WEBSITE.pdf (I am not affiliated, even though I keep recommending their shit lol... I am going to buy a Xtreme clutch soon) -
From Uniclutch "For the flywheels, both the R32 and R34 GTR are very similar and share the same UniClutch fitment kit so you can purchase whichever you like. Just be aware that you would set it up according to the flywheel you buy. If using an R32 GTR flywheel, setup the UniClutch like an R32 GTR. Yes, you will need a pull-to-push conversion. We are working on a pull type UniClutch, however, this is expected near the end of the year. The OS Giken stuff works great." Trying to decide between these two flywheels - https://www.rhdjapan.com/nismo-lightweight-flywheel-for-sports-clutch-kit-bnr34.html https://www.rhdjapan.com/nismo-lightweight-flywheel-for-sports-clutch-kit-bnr32-bcnr33-r32-r33-a31-wgnc34.html Any others I should be looking at ? ... -
Yuh, which is why I said it is "flywheel minus drivetrain losses", which is essentially exactly what it is. Presuming you might lose up to 10% (for real) in the drivetrain, you get somewhat closer to flywheel power with a hub dyno than what you measure on roller when you are losing that same drivetrain loss PLUS the somewhat larger tyre-roller loss. Inertia can be discounted when measuring steady state, which remains an option with either type (unless stupid US inertia roller type, which should never have existed). -
I feel like it's something in the fuel, 10 years ago we never had an issue but now everything rubber seems to fail quickly whether it's E85 or 98. You can use a longer section and just put a loop in it, looks a bit ghetto but doesn't swell up. 500kw should be pretty exciting on the street. -
It's not even really flywheel power. They might assume it and state a flywheel power, but really, hub dynos are measuring it at the hub. Reality of hub vs roller, is the change in inertia, as wheel is gone, and as you said, removing a slip from tyre to roller. Anyone measuring power at the wheel hub, can not claim flywheel power, as we don't know what the losses are in the drive line, especially on cars that aren't brand new.
