I read the 1st line of the Performance Tilton flywheel blurb - it sez for use with a 7.25" racing clutch, so assuming the write-up is correct...One could also go s bit less aggressive with a lighter than stock flywheel but not as light as the Tilton...

is the noise related to the weight of the flywheel or it's smaller diameter...or is it the construction of the clutch?

 

the tilton flywheel is made for use with only 7.25" clutches...

Tilton has a variety of 7.25" clutches that will work with this flywheel ranging from all kinds of prices...

 

it is the construction.. the stock flywheel is a 2 piece flywheel that has a big chunk of rubber that absorbs the shock...

here is a blurb off of what comes supplied with the EXEDY Clutches & Flywheels...

ATTENTION
PLEASE READ BEFORE INSTALLATION

Please Advise Driver of Vehicle:

Installing a sports & performance clurtch to suit various vehicles, can transfer harmonic transmitted noises from the engine to the gearbox. This may also cause gear box rattle. These transmitted noises will in no way effect the performance of the clutch or vehicle and is accepted in the performance industry where engine / clutch modifications have been carried out.

 

Thanks for the clarification, Jason. Which Tilton clutch would you say would be the most similar to stock as far as being good for a daily driver?

-Chris

 

2 disk carbon carbon clutch.. but that clutch alone is in the high 2000 range... ... i need to check my pricing

 

Good God Ya'll! two large for an appropriate Tilton clutch was a surprise...maybe that's why when I just checked this thread, no one had yet recovered from the shock of being able to post.

carbon carbon...it sounds cool. we would all be made out of the same material as our clutches...

 

I have a few questions about the shifting characteristics. Does the flywheel quickly slow rotation from high RPM making it easier to shift faster? or Is it the less rotational mass that allows the syncros to match gear speeds quicker - making it easier to shift faster? and Just how fast is *fast*? For example, can you shift as fast as the amount of time it takes to pump the clutch? and last Will this setup reduce the occurance of redline shifting grind?

As for launching in first gear, is spinning the tires or jolting the car something that is unavoidable? or is it possible to be smooth with practice?

 

you can shift as fastas you can move your hands.. there is no resistanceatall with thisflywheel...

jolting is unavoidable once you know howto drivewith it...

spinningtires you will do if you cant controll your right foot

 

JAS-

so do you concur about getting the flywheel only??? (for my situation, i am having FI with plen and exhaust....for now)

i want to exploit the FI (vortech) as best as possible, and need your advice!

huh?

You can not use the TILTON flywheel with any of the other available clutches EXCEPT for the TILTON clutches that are 7.25"

The stock clutch clamping force will handle FI but not as well as say the NISMO or JWT clutch...

We also have the Exedy carbon clutch & Flywheel available through us... It is the kind of flywheel and clutch that will last the life of the car...

 

ah crap............

im more unsure than when i started participating in this threadd (easily done!! for me.....)

can i talk w/ you sometime soon??

Hey Jason, what's the Exedy clutch look like, and when are you going to add it to your website? Does it come with a flywheel like the Tilton?

 

Jason,

Would you be able to use the JWT Flywheel with the stock clutch? If so, would you get the same accelleration gains and quick rev response as the Tilton?

-Chris

 

A friend of mine had had the JWT setup with flywheel and clutch. Not only is the car only slightly faster, but from watching jasons video, it doesn't even seem close.

 

Yup, it's not just about weight, it's about where the weight is located. I don't remember the stock clutch + flywheel weight but it's about 50lbs if I remember ok. The Tilton is about a third of that if I remember correct. Not only that, but it's reduced radius has a much larger effect than just the weight drop.

 

Here are pics f the some of the other units jsut for reference:

OS Giken (cerametallic single shown, duals also offered):



Exedy Carbon Single (dual disk coming summer '04):



ATS Carbon Twin (carbon single coming in June):

 

yes I can give you a call monday...

if you wanna call my room here in vegas... im just sittin here posting all weekend...

 

JWT Flywheel can be used with the OEM Clutch and any clutch that can be used with the OEM Flywheel.

JWT Flywheel can be used with NISMO Clutch, JWT Clutch, OEM Clutch etc...

NISMO Flywheel can be used with NISMO Clutch, JWT Clutch, OEM Clutch etc...

OEM Flywheel can be used with NISMO Clutch, JWT Clutch, OEM Clutch etc...

REmember, the clutch bolts on to the flywheel. So the FLYWHEEL and CLUTCH weight is combined!

So...

JWT FLywheel = 14lbs
JWT Clutch = 28lbs (If I remember correctly)
Total Weight = 42lbs

NISMO Flywheel = 23lbs
NISMO Clutch = 24lbs
Total Weight = 47lbs

Tilton Flywheel = 8lbs
Tilton Clutch = 8lbs
Total Weight = 16lbs...

So you have a total rotating mass of 16lbs with tilton, 42 with JWT and 47 with NISMO...

I will weight them again to be sure when I get back to the office on monday

 

here is some reading...

 

GREAT info, Jason! Thanks for posting that!
