SUPERCHARGER WITH STOCK CLUTCH

[Mitch]

Has anyone who has installed a SC had any issues with the stock clutch holding. If I run the car really hard I will get that burnt clutch smell. Yuk!!! To prevent this I am think I am going to an after market performance clutch. Clutchmasters makes the FX300 for the G35 which they claim has a smooth engagement which is something I would want since this is used for a daily driver. Has anyone installed one of these? Here is there link- http://www.i-m-racing.com/clfxstbahedu2.html

I have the JWT flywheel and clutch. Works well.

I am running the Nismo flywheel and clutch, and it works just fine. The stock clutch was not a problem either, but I do not do the 0-60 rev and drop it routine, so it might not be so great for that.

How do the Nismo and JWT clutches compare to the stock clutch as far as engagement when used as a daily driver?

They are very manageable. The take up is shorter and more abrupt, but with only a modest amount of practice you will find that you are shifting smoothly, and quicker. There is no real sacrifice in streetability, and the performance is better. What you really want to do, in my estimation, and I think Zimbo will jump in here too with an endorsement, is as long as you are in there doing the clutch, go to the lightweight flywheel. That is a real benefit and well worth the bucks if you are swapping out the clutch anyway.

I find myself agreeing with Eagle1 again.

I'm assuming that the Nismo clutch is similar to the JWT--but I've only tried the latter. People who drive my car (like a mechanic moving it into the bay) have a bit of trouble with the clutch at first and it's definitely more grabby than stock, but I got used to it after a couple of hours and it's extremely streetable. No problem at all.

I've done countless launches at 4500 rpms with a bit of clutch feathering and I've had no slippage. Never say never, but I'm fairly confident that if I manage to burn the JWT it's only going to be because of repeated visits to the local drag strip @ 375 rwhp.

The one thing I did that I'd recommend is having the RPM level at idle adjusted slightly. I found that the combination of the light flywheel and the supercharger belt caused my car to idle low. I had it pumped up by 150rpms and now it idles at around 700 rpms, making it easier in stop and go traffic.

Ah, now it is my turn to agree with Zimbo on an excellent additional point he made in his post. My car idles at 620 rpm, and with the belt drag at that low idle speed you can stall it from a dead stop very easily if you are just slightly off on the pedal timing. It does not bother me, but I really try hard not to let a valet ever get his butt in the seat at a restaurant etc.
For workdays however, I park at a club building a block from the office. All parking there is mandatory valet. They lads have been there for years and I know them all by name, the names of their kids, wives etc. They are busy parking bentleys and astons, ferraris, carreras...and then some really nice cars. SO they have excellent touch and are very careful. When I drag my tired fanny back after a day of work they LOVE going down the stairs to the lower level where they park my car, firing up the engine and having the whine waft up to the upper pick up level, then first gear cruise up the ramp and down the length of the garage aisle to the pick up point, with the limited slip diff chirping on that slickly polished surface in front of everyone in their suits waiting for their MB sedans. Eyes bug and jaws go slack. It just puts a big fat smile on your face. Everytime. I love those guys!
