403 LS2 FD - LS7 Build for 2020!

Funny you had issues with the LT1-S. I got one of the first when it was released. Had the same vibration. The PP holes and pins were off center something like .050"!!! Took it to a local machine shop and had them redrilled and balanced. Like butter. Steve at monster didn't believe me until I showed him the run out with the whole setup on a lathe.

Can't have an off center PP hole

I think I got an early one too...maybe it has a similar issue, but I've now had 2 clutches without sprung hubs behave the same way.  I have a growing number of people confirming the same problem.

An off center PP hole is always a mess!

I'm surprised the RPS did it though. If this DCT thing doesn't work out I was planning on running one.

I have an RPS clutch as well.  I haven’t noticed that issue.  I do have vibrations due to the power train being mostly solid mounted but nothing related to the clutch that I’ve noticed.
Btw now you will get more noise and vibration from your diff due to the urethane mounts.

Went back and found a vid I took from 2018 with the LT1-S lol.  The RPS did the same thing.  Going uphill or dragging the brake at 1800 in 4th and loading it up some it would really vibrate like a mofo.  Not like poly vs rubber bushings, but like the entire cabin is resonating. 

I have poly bushings in the upper mounts of the rear end already.  I'm happy to put poly bushes in the front ears.  The factory rubber explorer ones are sloppy as hell and contribute to wheel hop.  The diff noise I was griping about was horrible gear whine from improper gear setup.  I've always read, but never trusted that aftermarket gears are whiney and the Ford Racing are quiet.  Maybe it was me, maybe it was the gears...but it was bad a few times.

Great to see your progress here!! Yea the Ford gears are the quietest in my experience. That is not to say they are quiet.. but better for sure.

Thanks man - glad to see you back posting a bit!  I just got an ad for power tour west I didn't know they were doing one out here.  I'd be curious to hear how your experience is.

Thank you!

I think the info for Power Tour West came out 3 weeks ago, and you couldn't even sign up until a week and a half ago. I really don't even know the schedule, so we have several hotel reservations for 1 or 2 nights in Vegas so we are covered.

I ordered my 8.8 complete assembled from grannas with the ford racing gears, and I literally cannot hear the gears. My diff is solid mounted too. There is zero whine at all. No one could believe it lol.

Mine is silent as well.  Cobra 8.8 with stock LSD.

Do you guys also have solid metal subframe and diff mount bushings?

Superpro rear and stock Ford front here.

Mine were poly upper and rubber front.  Now poly in both.

My gear noise was simply from a bad gear mesh.  It was the classic super high pitched whine at specific speeds on accel side.  Of course right at highway speeds.. all of my gear sets up until now have been aftermarket though, not Ford.

Yellow is the new setup.  Blue was one of a few previous attempts on setup.  One set of gears I pulled out was worn significantly different than the pattern that went into it.

I can't say the new pattern is what I expected to see...but what do I know I've done 3 of them wrong now.

Poly and rubber bushings quiet things down a lot.
