I have a 97 Supercharged GXE that is putting down 286HP/240TQ. It did this as an A/T in 3rd gear (as best as we could...A/T seems to be a little tricky on dyno's). I am doing the 5spd conversion and have settled on a ClutchNet 6 Puck - Sprung Hub kit. However, the original Pressure Plate in the kit is rated to 450TQ and the kit is 450 (after shipping). They have an option to get a lower rated PP that is rated to 325TQ and the kit is only 325. I'm tight on money..very tight. I also understand that the TQ laid down in 1st gear is significantly higher than in 3rd, but how exactly is that calculated (what are the actual gear ratios on a stock M/T)?

I don't plan on adding anymore boost or major modifications in performance beyond a cooling system. After the 5spd...I'm happy where she's at.

That being said, what would any of your recommendations be in this scenario?

Thanks in advance.

 

Sounds like massive overkill to me. You don't need a 6 puck clutch and 450tq holding capacity for 240tq man. Unless you are taking your car to SIGNIFICANTLY higher power levels, you are sacrificing driveability quite a bit for no added performance, because it's just too much clutch for you. If for some reason you do stick with the 6 puck, at least go with the cheaper, and less overkill 325tq pp.

The 6 puck sprung hub is that I have in my car, and its pretty harsh engagement, not quite on/off but fairly close, and the chatter is really severe... it shakes the car. It is what clutchnet recommended for a car putting down 650tq, but still with the needs of a sprung hub for street use.

The torque difference you are talking about in different gears is torque multiplication, and has nothing to do with your clutch decision. It's a whole different concept that has to do with the gearing of the vehicle and zero to do with the clutch.

 

Is there another clutch you would recommend in my scenario? I was going to go with Clutchnet's 6puck sprung because Iansw really likes his. It should be noted to that I put slicks on this and hit the track about 4 times a year. Avg about 30 total runs a year

 

ACT Street/Strip Clutch, I've seen it as low as $280 around here. Feels like stock on my car with 3.25 pulley @ 10psi.

 

SPEC Stage 3 clutch kit for an 84-86 300ZX Turbo.

515 ft. lb. of torque holding capability, costs $319.95 from www.nipponpower.com

SPEC Stage 2 clutch kit for the 84-86 300ZX Turbo

450 ft. lb. of torque holding capability, costs $305.95 from Nippon Power

SPEC Stage 1 clutch kit for the Z

395 ft. lb. of torque holding capability, costs $275.95 from Nippon Power

Stage 1 and 2 are full disks with sprung hubs while the Stage 3 is a 4 puck sprung hub clutch. I bought the stage 3 and it works pretty good. I didn't break it in correctly though so I think I put some hot spots on it though. Overall I recommend one of these due to the torque capacity and the price.

All of the Maximas from 85-99 use the same clutch kits. The 84-86 300ZX Turbo clutch kit bolts up to the flywheel on my car (300ZX used the VG30E(T) same as in the 3rd gen) so I'm positive it will work on the VQ engines.

The only thing that won't work is the throwout bearing. That is the only difference between the two kits for the Z and Maxima.

 

I Love my ACT paired w/ fidanza.

Hmm...I've heard the Spec name dropped in different convo's but haven't really heard much about em. Do they hold up under "drive it like you stole it" conditions? What I'm concerned about is getting on the track with slicks on and blowing the crap outta first on launch.

 

"Drive It Like You Stole It" That phrase can be precieved in many different ways, Any clutch out there can fall victim if abused.

I am aware that Iansw had an unexpected expierence with his ACT/Fidanza Setup however there are many Boosted Org. Members that use this setup or at lease the ACT and have positive results.

There comes a point where its not the clutch you need to worry about, but rather what the transmission can handle. I don't know your future plans for your maxima, and if you continue to use it as a daily driver but from what I understand your plans don't really warrant the need for a 6 Puck.

I think you should factor in overall driveablity and price for your application, ie. ACT Street Modified, Exedy, etc.

I think the Spec clutches are pretty good. I'd actually absolutely love to have an RPS clutch but I don't believe they make them for our cars yet (the carbon version). They are pricey but nothing short of ****ing awesome. They hardly wear at all but if they do, the carbon surfaces are replaceable instead of buying a whole new clutch.

If only multiplate clutches were available for our cars... when I get the TTZ internals in my other engine there might be a possibility of stuffing in a multiplate... but that might take some work and would most definitely be over kill.
