Weird noise, clutch slip?

[svt boost]

Noticed something weird the last few times I have taken the GT500 out...in 4th gear at low RPM, when I put the peddle to the floor I hear a strange whirring noise from my right ear, and a "woomph" (best way I can describe it). It fairly loud, and each time I immediately take my foot off the gas.

Hotter than hell here so unsure if it is a power issue. Wondering if it could be my clutch or something? Doesn't slip otherwise, and I haven't been able to correlate the RPM's rising when this happens. I know this is vague but if anyone has any ideas let me know!

Has that car ever had a Clutch TSB performed? If so with what clutch kit. The early 2007 and 08 cars had some issues and they used the same clutch. By the 2010 year they started fixing the 2007-2009 cars with the 2010 style clutch.

No, stock clutch 22.2K miles and the whipple since 14K. I think it might be the clutch, just took it out again and the RPM's are bouncing up a bit in low rpm/high gear, then it catches and goes. Crap! I think the noise from before was when it was really hot and slipping more.

Supercharger belt slip maybe?

I have a spec 3+ clutch and billet flywheel waiting to go in when mine starts slipping and I have a quote from Dallas mustang for $275 on the installation. Thats a pretty good deal, I shopped around a few other places in the area and they ranged from $350-600.

I don't think so, because why would it start now? Also, the revs bounce, which shouldn't happen with belt slip.

That is a pretty good deal @ 275. Wonder how many they have put in for 07+ GT500's?

I got a quote today from HPP for $95/hr @ 4 hrs

Clutch is going. It's only going to get worse. I recommend SPEC. Stock 2007 clutches will let go anywhere from 100 miles to 40K. It's just a matter of time.

What spec twin disc do you recommend for aftermarket supercharged applications?

P trim

Correct me if I'm wrong. But if his clutch is going then more than likely it is because of the TSB flywheel warp issue right?

Since that can cause tranny issues should he not have his tranny dropped and checked out just in case?

Clutch disks are normal wear and tear items, just like brake pads. Not every stock 07-09 nodular iron flywheel warped causing clutch drag and hence the TSB issue! :bash:
