I suck at math and only loves to look at the outcome.The difference in diameter is just the wheels but not the overall diameter, at least not significantly. But the weight difference are significant there. This is talking about transferring power to the ground. If there's no additional power going to the ground to move the car quicker then what does?? Power at the engine is the same but there's not as much loss used to rotate the mass of the wheels hence enabling the power more to move the car.
dont forget me. i want to TT in MLK for discounted advanti.Then i should start making friend with their staff. Most probably can get something at discounted price...hihihi
Ok I'm beginning to see the disconnect now. What you're saying here is you'll potentially regain some lost power. You won't gain power like what was said originally. This much I can agree! But I also did say the gains is minimal in the beginning.The difference in diameter is just the wheels but not the overall diameter, at least not significantly.

You know what we should do? We should start a ZTH video channel where members get together to properly mythbust or discuss topics like this and share on Youtube.I suck at math and only loves to look at the outcome.
However, since we all agree that gb eats up some hp from the engine thus making hp at the wheel lower to hp at the flywheel...i am guessing whatever parts (including the rims) which are there to transfer the power from the engine to the road will have impact in hp figure. Its a matter of how much.
Would be interesting to see a dyno chart though. Then do the dyno again...this time removes the drive wheel disc brakes...i would love to see the outcome.

Cuz I sure would like to see for myself how this'll turn out on a wheel dyno and hub dyno.
erm..... hp vs bhp??love the discussions here.
Maybe we need to define what is HP?
HP rated at engine or HP rated effectively on the ground (BHP)?
Engineering Explained has a very good point on rotational mass. Having a lightweight piston, crankshaft, driveshaft, flywheel and all parts that delivered power to the ground essentially increases BHP and probably slight increment in HP rated at engine for the same engine capacity.
Nope the 5% difference he mentioned is not the rolling diameter difference but he expected around 5% difference in dyno results! The 20' tyre he used was 255/35/20 while stock 18' should be 235/50/18 which is actually bigger rolling diameter than the 20' tires! So despite running bigger rolling diameter, it actually got 20whp more than the heavier 20' setup with slightly smaller rolling diameter. To me it's pretty conclusive. I had seen many other tests long time ago but just cannot find them anymore.Ok I'm beginning to see the disconnect now. What you're saying here is you'll potentially regain some lost power.

Diameter of the whole wheel package (tyres and all) between a 20" and 18" is pretty significant. Based on the dimension given by the bloke in the 2nd video, it's roughly 5% difference. That alone would contribute to the slower acceleration on top of the wheel weight. Anyway, the 2nd and 3rd video has too many discrepancies. What we should do is make a video comparison between same diameter, same tyre and just a difference in wheel weight.
Anyway thinking too much about this is giving me a bloody headache. I'm done thinking. Hahaha! We all generally agree that lightweight means more better.

i think you want to discuss crank hp (i believe this what you are referencing to as is the bhp) vs wheel hp (at the wheels)
hp vs bhp, no real point thinking bout it
Very nice ownerhave you all heard from Kean Lee Hin store at jalan ipoh, which is one of the authorized supplier for Advanti rims?
If the factory can sell direct, then okay. Like my ex company, the factory only manufacture for export and sales to local sales company for local sales. Even factory staff who wants to buy the goods, need to get then through the sales company as the factory cannot sell direct...Then i should start making friend with their staff. Most probably can get something at discounted price...hihihi
the 5% I'm talking about the size difference based on tyre profile and wheel size. Not what the dyno was referring to.Nope the 5% difference he mentioned is not the rolling diameter difference but he expected around 5% difference in dyno results!

Hmm I think that should not matter much if at all as long as the rolling diameter is about the same. Weight on the other hand plays a significant role.the 5% I'm talking about the size difference based on tyre profile and wheel size. Not what the dyno was referring to.
It's not conclusive to me. But to each his own.
