datzenmike Posted January 1, 2010 Report Share Posted January 1, 2010 You can have the stock one machined down if you know a place. Here's where to remove material. Have it balanced. This is the cheapest for the lightest that I know of. Cost is machining and balance. Don't know the weight, probably under 16lb. Lightened flywheels are overrated like most performance stuff. The closer to a race car, the less enjoyable your car is to drive. 1 Quote Link to comment
HRH Posted January 2, 2010 Report Share Posted January 2, 2010 I checked into that too. Unless it's a full race, there's not much point. Lightening a stock L flywheel is a tricky business. Take off material on the wrong areas and it's crack prone. Not that you can't do it, but it will probably cost $100-$150 worth of machine shop work. Make sure they know what they're doing!

dat u racing Posted January 2, 2010 Report Share Posted January 2, 2010 10,000 rpm makes a lightwieght clutch/presher plate but it cost $850.00 basicaly arm and leg. anyone know of another brand? 1 Quote Link to comment
datzenmike Posted January 2, 2010 Report Share Posted January 2, 2010 Rid the spinning weight by adding an aluminum drive shaft, alloy rims, lighter tires. Rear disc brakes instead of drums, aluminum crank pulley. Quote Link to comment
HRH Posted January 2, 2010 Report Share Posted January 2, 2010 There was an aluminum z flywheel available a while back. Think it was in the 200-300 range. Can't remember which company tho. Quote Link to comment
72240z Posted January 2, 2010 Report Share Posted January 2, 2010 Mentioning what engine would prob help lol. Fidanza makes a 200mm, 220mm and 240mm, 240mm which I assume you would be needing for that d21. That's the cheapest store bought I know off. That or like suggested prior lightening a stock one. Expensive would be z1, stillen, rps etc... lots of choices. Forums and ebay are prob your best bet if you need cheaper. I sold a 13lb lightened 200mm 2 weeks ago for 50 bucks on ebay and I member hear picked up a 15lb-ish fidanza style from me like a year ago for 100 shipped. Not going to get any cheaper then that.

datsun510 Posted January 2, 2010 Report Share Posted January 2, 2010 Fidenza offers an aluminum flywheel. Get the 200mm clutch surface so you can use the Roadster clutch assy. Then there is always the small diameter quartermaster flywheel setup in single or dual disk but big $$$ and requires a special offset starter. Best to check the rules and see what is legal. When we ran a cricle track 510 alum flywheels were illegal but my friend had a old HKS lightweight steel flywheel which was legal by the rules and only weighed 10 lbs, made a big difference coming off the corners.

72240z Posted January 2, 2010 Report Share Posted January 2, 2010 Why would you purposely use a smaller flywheel to suite a clutch or flywheel when you can get a clutch/flywheel to match ANY size clutch? Seems like bad advice to me. Quote Link to comment
datsun510 Posted January 2, 2010 Report Share Posted January 2, 2010 The advice is great for all out road and circle track racing. It all comes down to inertia and how quickly you want something to accelerate or decelerate. Remember he is asking about a light clutch assy for a race car (truck). You also will not have any resistance to using the engine to slow the vehicle (don't ask me how I know). Same reason people want to use the smallest diameter rims possible, reducing rotating mass. It is great for racing but terrible for the street. Seth Quote Link to comment

Seth Riiiiiight You can get a 240mm (which comes stock on his truck btw) just as light as a 200mm. I stand by posting loosing 40mm of surface area be it to run a roadster assembly or w/e reason you want to list after the fact is bad advice. Quote Link to comment

dat u racing Posted January 2, 2010 Report Share Posted January 2, 2010 he is looking for CLUTCH/PRESURE PLATE lightwieght for racing 225mm flywheel 1 Quote Link to comment
72240z Posted January 2, 2010 Report Share Posted January 2, 2010 Well his options are all laid out for him, and then some. Guess thats a ka in that hardbody. If that's the intended car anyway. I would upgrade to the 240mm. Quote Link to comment
MAG58 Posted January 4, 2010 Report Share Posted January 4, 2010 If that's the intended car, I wouldn't get a lightened flywheel, just get a ZXT flywheel at 240mm. You're going to miss that inertia on hill starts and maintaining speed though changing altitude when you've got a loaded bed. Quote Link to comment
rpm Posted January 5, 2010 Author Report Share Posted January 5, 2010 Im not worried about hill starts, my truck is for circle track racing only. Sorry for not making that clear. 1 Quote Link to comment
hang_510 Posted January 5, 2010 Report Share Posted January 5, 2010 I stand by posting loosing 40mm of surface area be it to run a roadster assembly or w/e reason you want to list after the fact is bad advice. the clamping force of the roadster PP is significant over either stock. worth the small loss in surface area. i had a stock FW lightend to ~16lbs for $55 Quote Link to comment

I actually don't believe that the roasters clamp force is is "significantly" greater over those 2 stock. Over a stock 200mm sure. I'm aware the roadster has high stock clamp force, lets say for convos sake it's even the same as the 2+2/turbo. Doesn't it seem odd to buy a lightweight flywheel and after market clutch to then bolt on ANY stock p plate? Doesn't it make more sense to have more surface area AND clamping force? Especially on the track where it's going to be beat on? I picked up my act p plate with 5k miles on it for 25 bucks, its 55% more clamp over stock. 40mm isn't a small loss either it's 20%, that in my book is major lol. I would never sac that for a stock p plate, ever. Quote Link to comment
rpm Posted January 6, 2010 Author Report Share Posted January 6, 2010 Never mind my lightened flywheel is just fine. Your right about the smaller diameter clutch, much less turning mass weight. Now im going to install a center force clutch for a 510 onto 225mm flywheel. Hows that grab ya. :fu: 1 Quote Link to comment
banzai510(hainz) Posted January 8, 2010 Report Share Posted January 8, 2010 a 280Z turbo 2+2 pressure plate will make a Centerforce look like a popcicle stick Quote Link to comment
hang_510 Posted January 8, 2010 Report Share Posted January 8, 2010 Do you have the stock roadster/2+2/turbo clamp forces handy to prove that? . roadster - 650kg 2+2 - cant find... turbo - 550kg Quote Link to comment
banzai510(hainz) Posted January 8, 2010 Report Share Posted January 8, 2010 200mm Roadster 650kg 225mm 2 seat Z 750kg requires later T/O sleeve 240mm 2+2 and turbo 800kg from nissanmotorsports book 1 Quote Link to comment
72240z Posted January 8, 2010 Report Share Posted January 8, 2010 Ya, thought so..... It would be self defeating to use a p-plate with less clamping force on a 240mm then on a 200mm 240mm=win THE END lol Quote Link to comment
