Hah, nothing compared to you man!

I’m happy as hell with my garage, especially getting to put it to use, but I’m still a little bummed I wasn’t ready to buy when you were selling your place.

I the RPS BC2 clutch is amazing except at 1800 and 3600 rpm.  Ruins the effect of the car unless you drive around those RPMs.   I was hoping a $3500 clutch would be noise free.  That said between that and the magnum the car is amazing to drive fast.  It’s only when I’m not driving aggressive that I notice the vibration through the car.  Some nice upgrades!!

Vibration or rattle? Your clutch assembly needs to be balanced better. 1800 and 3600 are first and third order harmonics. I'd bet it vibrates at 5200 as well but it would be far weaker than the other two. I had one of the first LT1-S from Monster and they messed up the machining of the locator pins and the pressure plate was off center by .050". The vibration at 1800 was quite bad.

As a not that vibration is not good for the main bearings.

My LT1S does the same as Kinger’s RPS at 1800 rpm. It shakes the whole car. And yes clutch vibration can be hell on the rear mains.

I just drove around it, but I have 3.90’s so the shorter gearing makes it a bit easier to do. At 3600 mine is fine because I can’t lug it in 4th at 3600 lol too much beans at that point.

Super weird that many people are having issues. I had my whole clutch balanced as a unit by a machine shop and it's been awesome ever since.

Got a lot done today!  Waiting on a few parts for the trans, but have a lot I can get done in the meantime.  I'll clean up and bust the trans apart so I can inspect the reverse gear assembly.  I'm hoping it was just a shifter issue, but I'm prepared to pull reverse if I have to I guess.

Figured out my cooling fan situation.  Very pleased with this...saving a boatload on new fans that can now go back to Amazon.







My girl has been helping me a ton.  She gave me shit the other day that she doesn't get to do any of the fun stuff, so she basically did all the work on getting the trans ready to pull, and then did all the wrenching to swap clutches today.  I barely spent any time under the car today lol.



I'll be hanging onto the LT1-S.  It really is a fantastic clutch.  It'll either make its way back into this car, or into something else in the future I'm sure.  It looks great coming out, and I was not easy on it.

Out with the old 50 pound unit





In with the new 31 pound carbon carbon hotness

Oh yeah and last thing I did for the night is measure the air gap for the clutch and I'm right mid-range with all stock stuff.  I've never had to shim a clutch before.  Honestly never measured for it until today.  Lucky?  I've read so many people having trouble with shimming the heights properly and my stuff just seems to go together as is..

Right on man! That is awesome your girl wanted to help out, my wife someday may be up to that......maybe after her hatred for the FC finally subsides. 


What have you read about the engagement on that particular clutch?

Let’s go for a drive when you get the car all back together.

Yes definitely!  ACH is what broke it lol so I'm looking for redemption.  My buddy just went up today and said there were a ton of cyclists, cops and slow drivers, but he got up late.

Yeah she's always been excited to jump in and wrench, and has more motivation and energy than I do so that helps too haha.

The clutch is supposed to have the ability to slip like a normal friction, but takes heat and abuse like none other.  We'll see.  I expect it to be a bit like how everyone says every single aftermarket cam drives "like stock".  Unless it is a stock cam, it isn't going to drive like stock lol.  I'm on the extreme end of tolerant of bullshit in this car so long as it serves a purpose.  My diff whining makes me want to park on train tracks, but I ponder what life would be like with a faceplated trans...one is a flaw, the other is a feature haha

Clutch talk is the automotive equivalent of talking politics or religion...

[Cobranut]

Wish I could get my wife under the car. 

You're gal sounds like a keeper, and she's cute too. 

[kinger]

My experience is it doesn’t slip like a stock clutch.  The pedal pressure is light but that’s about it.   I had to learn to drive a stick all over again killing it on first drive lol. 

It’s definitely a drivers clutch.  I wished I would have done something less aggressive but I’m not yanking the trans again.  I’m also on the picky side of wanting a full on mod car to be like a OEM car.  So don’t listen to me if you pound the car and drive it aggressively in those canyons you have out there. I think this is the clutch to have in that application.  It is SUPER fun to drive with the satisfying click of the gears with seemingly no effort on the Magnum. 

Enjoy!!!

Did you get the steel, lightened steel, or aluminum flywheel?  Mine is the full weight steel.  If I bought it new I'd probably put the aluminum in just to be a masochist lol.
