Chris, I was wondering about the weight of the flywheel on this clutch by itself, according to the site it states:
Including a light flywheel, the clutch and flywheel assembly is much lighter than factory clutches - 11 lbs compared to the 1991-96 factory clutch assembly and 19 lbs compared to the 1997-2005 factory clutch assembly.
I believe that the oem dual disc clutch is superior to oem single disc due to lower MOI but Honda made the switch because people were having trouble with the initialization procedure not being followed and resulting in almost immediately worn clutches and complaints. When I last replaced my clutch, I used a 7 lb aluminum flywheel with the oem dual disc clutch and the results have been fantastic, with 45-50k miles on it so far so longevity of the dual disc has not been a problem for stock HP levels. The OEM single disc also seems to have plummeted in value, mostly due to its boat anchor weight and mediocre performance I would think. I realize that the SOS clutch is single disc and designed to be a more performance oriented single disc but was this design pursued to reduce complexity? Performance over the OEM unit should be much better given it's almost 20lbs ligther but I am wondering if that is mostly in the flywheel? I have seen some lightweight flywheels in the range of 13-15 lbs so I am wondering where this one weighs in, and if it is lighter than my current setup. Also, do you know the weight of the two OEM flywheel options without the clutches? I remember finding the weight and it was really heavy but I don't remember it. Obviously the SOS clutch is capable of holding more power than the stock clutch, so I am also wondering if it has to be "beefier" to do so.
