Should a new clutch smell right after install?

[robr]

its been mentioned before that some people had problems with earlier nsx's giving up the clutch very quickly, i haven't seen much about it happening on later years. my 91 started slipping very early on, around 13k if i recall (feel free to do a search on my older posts ), it was completely gone by 18k or so. i replaced it with a slightly used clutch from a 97 that a fellow prime member sold me for pennies. i've put almost 90k miles on it without issue.

Using a one disc clutch from a '97 model for an older one requires some modifications AFAIK - how did you do it?

OTOH: My experiences with the OEM one disc clutches where worse than the experiences of most 2 disc clutch cars in my former club (the older models where in majority) - theirs did fail very rarely, mine twice after less than 10k miles (with track use and race slicks). Of course that could also be due to my mercyless driving behaviours :wink:

Also, the NSX's relatively low torque in the lower revs shouldn't have slipped my clutch in first place in my opinion.

The NSX torque is not that low. The difference to other cars (especialy to FR cars like BMWs) is the very good traction of the NSX. When you do a race start other cars tend to spin the wheels, the NSX can spin the clutch before the wheels do (been there, done that). When german car mag "sport auto" tested the first 3.2 l model in '97 they had to stop the 0-100 km/h acceleration tests because the (new) clutch failed.

NSX-Racer,

You can install a 97+ clutch in a 1991-1996 car. The mainshaft is longer in the earlier setup and the clutch will work. What you cannot do is install the dual plate older style in the newer cars, since the mainshaft in the six speed is shorter. You would need to go with an NSX-R mainshaft in the 6 speed to use the original dual plate clutch with the six speed, as the NSX-R does.

HTH,

I agree that the traction of the NSX's MR design is much better than a typical FR setup. However, I would have thought the NSX's clutch was strong enough to allow the tires to spin from a rest. Then again, I have not attempted a burnout in the NSX.

Thanks for the info in regards to the sport auto test. That is very interesting.
