Re: What Is The Lightest Streetable Clutch Available for Use with an Aluminum Flywhee
I remember looking at the bad boyzz garage system. Nice system, but I don't really think it is any lighter than an oem clutch and aluminum flywheel and it is alot more expensive. I think the flywheel is a lightweight steel design and not sure of the clutch itself but when all said and done it saves weight over the stock oem flywheel and clutch but not the aluminum flywheel and oem clutch or not much. Someone please correct me if I am wrong.
Weight is not as important as Mass Moment of Inertia [MMOI]. This is how it will "feel" to you while driving. There are also multiple instances of how this applies. For example, a low MMOI of the clutch pressure plate and flywheel will make the car difficult to move from a stop, while increasing the rev-matching speed. However, one facet that very few people actually take notice of is the MMOI of the clutch disc itself. THIS is the mass that the synchronizers in the transmission must deal with directly, and will have an impact on how fast you can physically engage gears, and how smoothly it will operate. There is a lot of homework to be done on an application before you dive into a decision.
Final GTS do you have any experience with the improved clutch/flywheel systems you are referring to or does anyone else? Are they lighter and how much and do they work well on the street. I have seen some exotic setups for race only but that won't work on my driver and 6k is a bit much for a clutch when oem is around 3 to 4 hundred.
Haha, to put it simply... YES. *cough* read my profile, I am not an "enthusiast" *cough* I have used just about every multi-plate clutch in existence for the Viper, and brought the Tilton Heavyweight system to this market about 5 years ago. I have extensive experience with Tilton, RPS/RSI, McLeod, Spec, and of course all of the stock clutches.
Advantages/Disadvantages:
Cost $: <500
Cost $$: <1,000
Cost $$$: <2,500
Cost $$$$: <5,000
Cost $$$$$: <10,000
[For the sake of argument, I have assumed the "top of the line" of each type. Tilton Quads, RPS Triples, and McLeod Twins. Spec and Stock are of course single disc. Costs can vary greatly if you dont have the need for a high Tq capacity, as you can get the benefits of one system type while not breaking the bank due to costs of extra carbon/metallic plates for the high capacity systems]
Tilton Lightweight Carbon: Ideal Floater MMOI for shifting, ideal driven MMOI for track rev matching, smooth engagement, immune to overheating, very high TQ capacity / NOT streetable due to stalling, cost = $$$$$
Tilton Heavyweight Carbon: Ideal Floater MMOI for shifting, ideal driven MMOI for street but still trackable, smooth engagement, immune to overheating, streetable, very high TQ capacity/ cost = $$$$$
Tilton Lightweight Metallic: Ideal Floater MMOI for shifting, ideal driven MMOI for track rev matching, smooth engagement, very high TQ capacity / NOT streetable due to stalling, cannot be slipped heavily, cost = $$$
Tilton Heavyweight Metallic: Ideal Floater MMOI for shifting, ideal driven MMOI for street but still trackable, smooth engagement, immune to overheating, streetable, very high TQ capacity / cannot be slipped heavily, cost = $$$
RPS/RSI Carbon: ideal driven MMOI for street, smooth engagement, streetable, high TQ capacity / heavy floater system can slow shifting, not immune to overheating, cost = $$$$
McLeod Metallic: ideal driven MMOI for street, smooth engagement, streetable, high TQ capacity / heavy floater system can slow shifting, not immune to overheating, cost = $$$
Spec 3+: ideal driven MMOI for street, moderately smooth engagement, streetable, moderate TQ capacity / heavy floater system can slow shifting, not immune to overheating, cost = $$
Stock: ideal driven MMOI for street, smooth engagement, streetable, low TQ capacity / not immune to overheating, cost = $
