Excited to finally get my SC dialed in and taking out for my first joy ride today and all of the sudden I am hearing an interesting vibrational noise like a scuffing or rattle. The sound feels like it is coming from the trans for sure. I have an idea what it might be but am hoping to narrow it down if not get some consistent feedback on what the problem is for sure so I can direct my attention to this and not spend big bucks trying to find the problem before even fixing it.

Sound does not happen when car is moving with clutch in, it does sound at cruising and under throttle both, It also happens when decel with clutch out in gear. Does not seem to matter which gear it is. When parked that car does not make the noise, it has to be in gear with clutch out. The trans shifting feels good and goes in every gear no problem, nothing there has changed, just the sound when driving in gear with clutch out. Let me know if you have any questions

Thanks for your feedback!

Took it for another drive, something to add -- I can feel the shifter vibrate as I hear this hollow sound, almost sounds like something is lose inside the bell housing and is resonating. I should state that I do have a Findanza 8 pound flywheel. have been running it for a bit more then two years with no issue.

 

the blower may be loose. check all bolts and report back.

 

The blower is tight

 

Check the crank pulley.
