Drivability has to be just horrible.

Actually, it isn't. There is less slip in the clutch and it is more grabby which some people may think makes it more difficult to drive. But I believe the only people who would feel that way are people who are not very good at driving a manual transmission in the first place. After I drove the car for the first time there is no way that I would go back to the stock setup.

You don't have to break in a clutch, it's not like your engine... It's either engaged or not, or worn or not, or broken, or good...

Good comeback.
But, I still disagree with you.

Can you explain? Why would it make the car worse or less drivable with a lighter flywheel?

Those dyno results are excelent. I honestly didn't think a flywheel/clutch made that much difference. But the only thing I have to compare it to is when I did the clutch flywheel for my old Probe GT. I may have got like 3-5hp, it really wasn't worth it. That was a 12lb flywheel down from a 20lb flywheel. I never took notice to any drivability difference.

I am definatly getting the light clutch/flywheel in the future, maybe next year so don't PM me. I like mods that you can't see

Runs = #7, #8, #9

We took the best run with the stock setup and the best run with the Z1 flywheel/clutch setup. The charts are the best of the 3 runs for each clutch/flywheel setup. The runs were done on the same day so all of the conditions were the same.
You posted the best numbers for each setup. Do you mind posting the worst numbers for the Z1 clutch/flywheel?

Just my opinion after having a 14lb flywheel put in along with the super stiff & grabby nismo clutch. It is nice to drive well at least in the bay area but not in heavy traffic. Driving it is easy once you get used to it(takes about 5 mins to learn how not to stall and 1 hr to drive smoothly).

So you're saying there is no chance of the extra heat glazing a brand new clutch? So if you don't need to break in clutches, then you don't need to break in brakes either?

I guess I was always told the wrong info.

You can glaze it making it pretty much useless.

Mabye so, but I a the only one with one so I am the only accurate response. Some people may disagree but we did show a true 13 hp gain and 17 ft/lbs of torque and it will be available in two or three weeks and I am sure that all of their responses will be very positive.

2004DSC,

Good point. I was looking for the 3 worst numbers and the answer to Diesel1’s questions. I just want to write it off in my book as what to get when the time comes. You still love it? Why did they have to use your car? Don’t they have a test mule?

I have the JWT fly and its 14 lbs, and it drives very nice, I am not sure if that 1 lb makes that much of a difference.
