Clutch& Flywheel ????'s Need Advice

[len3.8]

Hello all I don't know what HP the CTSC puts
out, But I have the SC, Headers, Thermal exhaust, 6spd trans, oil cooler ec. ect. ect.
The car is very responsive with the 6lb.SC with a little tuning the car should be a little better.
I am very satisfied with the car, However I have a problem with the clutch it broke.
I don't know if it was the power or a defective unit. It only had about 2500 miles
on it. And I can drive, so it was not being abused. My question (finally) is what are you guys that have the high horsepower cars
doing for clutches and flywheels?
To be more specific the guys with the SC'd cars, I would like to get a quality clutch and flywheel set up for my car.
I don't drag race at all, so that isn't in the equation. I just want to make sure that I replace this with a proper setup, not one that just cost $$$$.
email offline if you want or if you are a
dealer of this kind of product I invite you to call me and tell me what you have.
It should be added that I have a 6spd trans
in a 95, I was told that I have limited choices.

Was it a factory clutch?

How did it break? 2500 miles is definitely short! Did it throw a spring or was it a problem with the friction surface or something else entirely?

I have a Comptech clutch on my supercharged car and like it a lot.

I am going to pick up what was supposed to be a comptech clutch, The fact is it is not.
Based on the the comptech authorized mechanic that is working on the car.
I will let you know in a few hours.

Which one? The powergrip2?
That is the one that I am considering.
Let me know how you feel about drivability
on the street and if you do any track events.
(Not Drag Racing) Not that there is anything wrong with it, just not into it with this car.
Thanks
Len

The Dali feather-light combo still looks like the best value, and I haven't heard any more problems than with CT. I'm sure either is fine.

Len is running a six speed transmission retrofit on a 3.0L NSX. Therefore, he can only run single plate clutches, such as the Comptech Powergrip 2. The only way to run twin disc clutches on the 6 Speed is to change the transmission input shaft to the 5 Speed input shaft.

Ha, good catch! My mistake, thanks.

Hey Len, I haven't seen you around, or have I? Do you work in the Kirkwood area or down in St. Louis City?

Ive got a Clutchmaster clutch in mine, with a lighter flywheel.

No complaints, solid feel, stiffer than stock but managable even in traffic, 35K+ miles on it, supercharged + NOS and still going

And for anyone who knows me, they know I drive the hell out of my car....

Yes, PowerGrip 2. It's very driveable. Just a bit stiffer pedal than stock (stock is very soft).

First of all thanks to all of you for the input. This forum is Awesome and the people
on it are very helpful. I just got this car
and I have been learning a lot from you all.
Thanks for the input on clutches.
ACR Motorsports is correct I am running a 6spd trans.
SJS I have only had the car for about 3 weeks
now. I was in Kirkwood last week at Reid Vanns , just so they could tech my car.
I plan on getting together with the NSX guys
here in St. Louis area, Missed the meeting on
July 20th, I was at tweeks trying to sell a Porsche.:^) I ain't going back for awhile.
I normally drive a 3.8RSR clone (Very Yellow) I know Nick M. and I have been to a
couple of track events at Gateway when he was running his NSX. That is when I really
started noticing him and the car. The Vette C5 was new at the time and he was with them all the time on the track.
LUD thanks for the input, I have a couple of questions that I will ask you offline if you don't mind.
Thanks to all of you for the input.

How original are these plate choices?
Remeber I am a Newbee, I don't want to take
somebody elses plate.
UVBNSXD NSXXDU NNSSSXX
I'm trying

They're original, but pretty obscure. Also, if you look here, you will notice that in Missouri you are limited to six letters or numbers. Unfortunately, that knocks out some of the best ones, like NSXTASY and NSXOTIC. I would see if you could get NSXTC or LENNSX or LENSX.

 

[len3.8]

I have the option to register the car in
Illinois. My company and home are in Alton, Il. Roughly 7 miles from St. Louis County.
That is why we just say St. Louis, If I say
Illinois we get Chicago as a reference point first.
I like LENNSX though.
Thanks for the link

It was Not a Comptech Clutch, and you were correct a spring appears to be the culprit.
A tab was broken off as well.
Can't be too sure, I only know that it is toast, Have pics I can e-mail if any one wants. But I now have to wait at least 2 weeks, no matter what clutch solution I order.

Aha!

I knew that, though. I've driven Gateway International several times. It's funny - there are several tracks where I drive 100 miles to a racetrack in another state. For Gateway, I drive 280 miles and never cross the state line.

In Illinois, of course, NSXTASY is already taken, and has been for almost twelve years.

But since you can get seven letters here, I would go for LENS NSX, with the space between LENS NSX. Some folks even paint on an apostrophe for LEN'S NSX. (Some states let you get the apostrophe as part of the plate number, but not here.)

The Illinois form to apply for personalized plates can be downloaded from here.

When was the last time you were at Gateway?
I was probably there. Haven't missed an event there , Porsche/BMW in quite awhile.
I like Motorsports so I am there a lot.
I remember an event whith about 3 NSX's attending, one being a local.
We were most likely at the same event.
LenNsx (it's growing on me) you may have Knighted me.

1998. I instructed at a PCA event there August 21-23, and I think we had 6-7 NSXs there. Unfortunately, as is often the case in St. Louis during the summer (where average daily highs are six degrees warmer than in Chicago), the weather was beastly, with highs around 99 degrees and humidity similarly unbearable. In addition to the track event, the NSX owners had arranged dinners together each evening (but the air conditioning at one of the restaurants was not working

).

A few of us attended the BMW CCA event there November 6-8 that same year, where I also instructed. I haven't been back since, mostly because of the weather but partly because I didn't like Gateway enough to keep it on my "short list" of tracks to which I return every year (Road America, GingerMan, Grattan, Mid-Ohio, Putnam).

I also drove the old Gateway for one of my very first track events in the late 1980s.

The input shaft of the 5-spd and 6-spd is not cross-compatible.

Researching a "shaft extender" product now with Mark Basch to allow a 6-spd tranny to run clutch/flywheel products designed for NA1. In the meantime, I'd recommend the Powergrip 1 or 2 which is a single disc. You will need the longer flywheel bolts from a NA1 though.

I understand about the heat, We just had an event last weekend, very hot. My car was one of many that were not up to the heat.
I was there in 98 with a few friends, one had a silver NSX was not in the event though.
He always comes to watch and talk shisk.
He has now purchased a 993, IMHO I think it was a bad move. It will never see the track.
I have been to tracks in Cali, Heartland Park, Putnam. I plan on expanding next year.
I am going to Memphis in November.
That is if a clutch comes in on time.
I plan on running the BMW event in November here as well. I am sure we will run into each other.

Wouldn't you rather drive along with 50 or more other NSXs

in a three-day all-NSX track event at two different tracks? If so, block off November 6-10 and come to NSXPO 2002! For you, it's only a day's drive away this year, and I guarantee that it will be the most fun thing you do with your car all year!

I was told by several japanese tuners that it will work(Maybe it doesn't). How do you think the Type-S Zero and New Type-R are running the factory twin plate clutch?

Remember an old (but clean) white Datsun 510 and a black '93 NSX last fall at the BMW club event? Those were both me. The NSX was fun, but I must admit I enjoyed stomping on countless BMWs, Porsches and Vettes in my little sedan even more. Sure, I know all the various reasons why that was possible, but none of that matters when you're blasting by one high dollar sports car or "ultimate driving machine" after another. Too bad the track is so crummy. The original course there wasn’t much, but it was better than the new one. Jeez I miss MAR!

What run group are/were you in 4 or 5, Or are
you an instructor. I remember an NSX on a day of the event, but not the entire event.
Sorta like me last week, NSX Kicked butt on Sat.Bought the Porsche out Sun.(held its own)
I remember the 510, I was in a Bright yellow
911. I remember the old track, I had just moved back to the Midwest from California.
I did not get to drive on that one.
You and NXSTACY do not like the track, what is wrong with it? I know there are better ones. I just don't see what's bad about it.
I wish it was a little longer,wider and had some elevation changes. The Oval portion intimidates some people. I will get to visit
many more tracks next year (GW) maybe I will
feel the same.

"Bad" is strictly a relative term; Gateway is fun but there are places that are more fun, that's all. I find the oval portion to be rather boring, and the infield course, while reasonably fun, doesn't have any elevation changes or camber to add variation to the layout. The most fun tracks for me are those that have vertical as well as horizontal variety, like a roller coaster.
