<<Top end speed and accelerationa re still the same as far as I know.>>

Top speed won't change since that is steady state. But acceleration can improve slightly. Downshifts are easier too. Here's a dyno test showing part of what is going on. Essentially you benefit the most when the engine changes speed rapidly. Such as in the lower gears, especially in those parts of the RPM band where the car can change engine speed rapidly. Look for the flywheel section on the page below. It's a moment of inertia thing....

Toda seems to be the choice for flywheels out there, but what about the clutch?

Is there such a thing as too much clamping force? After driving the S2K on the racetrack I find the forgiving manner of its stock clutch, alleviates some of the "shock" and "stress" to the tranny. I find the fastest way around the racetrack is keeping those RPMs up there, you end up shifting more than everybody else. Although that may depend on driving styles, I prefer staying busy. There is no doubt that the stock clutch is inadequate for strips. I've also dropped the clutch and slipped it all the way up to the rev-limiter going 2 mph, the burnt clutch smell lingered for days. However, on the track it seems fine. I red line at 60+ on 2nd, 90+ on third, 120+ on fourth, I haven't redlined fifth or sixth. It seems to cushion some "shock" on those hi-rev heel-toe downshifts.

Mugen consistently comes up with good products for the S2K. What would be the reasoning behind marketing a sport/racing clutch with 7 percent more clamping force? It may very well be the more clamping force equal faster times but could there be consequences to that?

Whatever happened to Reverend's update on his clutch install? Any comments, Scott from King Motors.... Anybody care to comment.

When I built V8 engines I always made sure the flywheel was balanced, even aftermarket units worked better if balanced dynamically with the other components. Are these aftermarket units balanced at the factory, or is the manufacturing so precise that they don

BBSpoon

Balance is GOOD! it's a must!

At $480, THEY'D BETTER GET IT PERFECT! But I'm assuming and you know what that makes of you and me.

Pepe doesn't seem to experience any weird vibrations, but there I go again, assuming.

Anybody knows, for sure?

Pepe

I don't think 3K miles is enough to be called experience but so far no problems with vibrations or starter engagement.

The part is of the the highest quality and I have seen people used these flywheels on other Hondas and have no problems.

One thing about replacing the clutch.

If the clutch no longer is the "Weak Link" what is?

There is a certain wisdom to Honda making the weak link in the drivetrain relatively inexpensive (compared to the rest of the drivetrain) to replace.

Bobway

I think the intent is to have the weak link to be the rubber to the road. Let out the clutch too fast, spin the tires.

Yea just dont go sticking 285's on the rears with slicks or our super sticky S02's! Stock they are sticky enough!
