Default KARS III Whine...

So I installed my KARS III blower kit today...

I say blower kit because the rear end whines constantly now, louder than before. I assume its driveline vibration thats being picked up through the solid mounts, but man... its kinda annoying.


On the up shot, wheel hop and traction issues arent an issue.


Has anyone had a similar problem?

I never installed mine, the only other car I drive with the Kars III howled like a bitch. Deleted cats and a 408 solved it.

Yu might try putting really thin rubber bushing under the mount points. It kind of defeats the purpose of the kit but a little rubber couldn't hurt that much. I'd also grease the crap out of it and see if that helps.

Im going to play with the bushings today, see if I cant quiet this thing down. This is a corporate-driving-clients-around vehicle, so I cant have it making un natural non - caddy like noises. If it doesn't quiet down its coming off and either going back to 561 or being sold here.

Those interested in purchasing it from me, stay tuned, I have a total of about 7 miles on it now.



EDIT:

The fix for the whining is painfully simple. I was looking at it today and realized that all I needed to do was:

Remove the pinion carrier bolts so that the rear bracket was no longer attached to the traction bars.

Then I hit the local Kragen and buy a set of rubber bolt on style bump stops and shave them down to where they fit in the pinion support area.

Now I have a daily driveable traction kit, with a pinion brace when I want to go to the track, just have to swap the rubber bushings for the two pinion bolts that attach the bracket.

Simple fix, howling is gone, and the V has no wheel hop issues.

LOL, I have your old KarsIII on my car. It amplifies the diff howl for sure.

I solved this issue via headers, cam and rolled down windows.
