  • Love the clutch and flywheel you picked for the job. I can see some serious top speed number in this things future.... That was one of my problems before when i turned the boost up to 12PSI. I would roll into the gas at 80mph or faster in 5th gear and the boost would come up the power would be there but unfortunately it would just rev up and slip the clutch. I know that most people get there top speed in 4th but to really ring this things neck you need to be in 5th.... That is where you can let the turbo pull and it won't sound like its about to blow up. I can't wait.......


    I was containing my excitement pretty well until i got the last email with the flywheel/clutch and fuel rail info. Now I am having to find stuff to do to keep me occupied. I guess I could start removing the engine. I don't see any reason not to at this point. I just wanted to make sure I would have it ready by the Georgia ride and that wont be an issue for sure now that it is actually partially assembled.


    Here is the clutch setup : 2.4L Performance Clutch by DDMWorks450lb of torque....!


    I won't push it that hard but it will defiantly get a little more than 350lb throne to it .

  • I was debating quite a bit on the different options for you, since there are just the clutch disc upgrades available. We have used the Exedy setups before, both the Stage 1 and Stage 2. Honestly though the Stage 1 exedy is just a little bit better than the stock clutch, the Stage 2 is better than stock, but the engagement is rather abrupt since it is a 3 puck clutch. That clutch upgrade by itself would be good if you wanted to stay with the stock flywheel, but since talking with you and deciding to go lightweight on the flywheel, it opened up the possibility of other options. There are the aluminum flywheels for the Exedy setups and there are also the SPEC clutches that are available, but with the clutch and flywheel they start being the same price as our clutch setup.


    Our clutch/Flywheel kit we are going to be using in this setup we first started installing on Solstice/Sky's in 2008, so it has been around and tested for awhile now. The clutch setup has a flywheel that is recessed for the clutch disc to sit into, with a relatively flat pressure plate. All of the aftermarket clutch kits follow a similar setup, except for ours. We were able to go with a flat aluminum flywheel and a pressure plate that came down to meet the flywheel, almost a reverse of the factory setup. By doing so, we were able to come up with the lightest clutch/flywheel available for the 2.4L. We use a 6 puck sprung clutch disc, which does engage a little quicker than a complete full face clutch disc, but offers much higher holding power. The clutch is still sprung though to help smooth that engagement still like a factory setup though.


    Looking forward to seeing how you like it :)


    Stock Clutch/Flywheel combo - 36.1#



    Our DDMWorks Clutch/Flywheel Setup - 22.8#



    Comparison between the 2, you can see how the stock flywheel is taller to pocket the clutch disc inside of the flywheel compared to our setup -


  • @rabtech all I have to say at this time is that your assets better make the North GA ride "WITH" a SlingShot. Already knew it was going to be a workout to just try and keep up. Now with this thing I can't even begin to imagine. Just gonna go ahead and call your SlingShot the Ghost because I ain't gonna see it. One moment it was there and then poof.... nothing but smoke.


    Edit: smoke as in tires smoking and SS just freaking gone
