Pucks sir.
In my experience you could tell when the material is starting to get hot because the clutch turns into a chattering light switch LOL. That is usually my cue to give things a cool down.
3 seasons on 150-175 Monte Smith plate kit + street driving all summer. I had to really abuse the clutch for the duration of last season because we added 150hp n/a. Ram Powergrip HD rated to 650rwhp.

How much pressure in the pressure plate?
That’s one thing about a diaphragm clutch in that I don’t know how you reduce plate load with changing the entire diaphragm spring.
A B&B cover you can take apart and change springs really easily. Or you can just take them out.
I’ve had 12 spring covers with only 6 springs to get the plate load down.
How all that relates to clutch tamer operation nor can I say if plate base load even matters with a clutch tamer.

Ram's 10.4" dia full iron disc paired with a 2800lb Powergrip PP has pretty poor street manners, even with a 'tamer on the pedal. Disc has a lite thin flat carrier, which means most of it's 5.1lbs is around the outer dia. Hard to slow down, not really an option for a synchro trans.
The 10.375" 900 series disc that comes with the Powergrip HD has the metallic material on both sides with a marcel and sprung hub, it weighs 4.9lbs.
The 10.375" 900/300 dual friction disc that comes with the regular Powergrip also has a marcel and sprung hub, which means more of it's 4.6lb weight is closer to the center. Easier for synchros to slow down, but won't shift as well as a lighter organic disc.
The 300 series organic discs are available with either marcel or flat carrier, flat carrier being the lightest and best for hi-rpm shifts with synchros.
Ram's Coyote Stock Special clutch uses a 6 paddle disc, but with much lower clamp pressure. About 2200lbs is available for clamp, shimming .050" reduces that to around 1550lbs which was close to race ready ring height for a gen2 Coyote's output. CS guys are faceplated with 1/2 degree sliders, not really streetable. I know of a CS racer that used the same off the shelf organic disc for a full season with a shimmed pressure plate, won the championship.
My test mule has a 9000rpm 355sbc that currently has a 250hp plate instead of the crossbar. The clutch i'm using is basically a regular Powergrip clutch with an off-the-shelf 2800lb pressure plate that's shimmed .060", paired with a 900/300 dual friction disc. I get away with that clutch because I have the n2o on a delay, doesn't come in until the clutch is locked up. Clutch looks almost as bad as yours when I take it apart, but has never welded. Slip is set for about 1.0sec during launch. Great street manners. Shifts great @ 8600 using the pedal, but I have a faceplated trans.

My thinking was most of that stuff has too much plate load to run a sintered iron disc on the street and not be pretty miserable to drive.

I wonder if the radials had a part in it. They were pretty violent when they chattered. Also the gear change it slipped obviously but maybe too much? I want to upload a video but don’t know how

You have to upload the video to YouTube and then post it here.
I’d love to see the video

Anyone know how to copy a video to photos on my phone?
I need to slow the video down better than what YouTube lets me.
TIA

Looks like around 4-1/2" of separation on that left rear, could the harder hit have maxed out the rear shocks? I'd probably put 20-22lbs in those radials.

It’s possible I don’t have shock sensor to tell but it’s very close. I had about 18 in them

You know how good I am with a phone. You know I detest phones that want to do more **** than just be a phone.
So to save the inevitable bitching by the old ball and chain when I stomp the phone for not cooperating I have moved on from trying to do it from my phone.
Now I’m trying to fight out why I can’t send the stupid video to my laptop from this phone.
This phone is skating on thin ice at the moment.

If so that’s a bad assed clutch. It’s sad that Ram has stuff like this but they put clowns on the phone who suggest junk when you call.
I started watching a video the other day where ACT clutches were being interviewed.
As soon as I saw a drift car driver was part of the show I turned it off.
Hopefully not many guys watch it and buy a clutch like that.

Yeah. I think it’s the only way to go.

Looking forward to sharing data once I get ours in the GTS. Does your bellhousing have an adjustment window?

I think RAM changed their customer service strategy for the better using the online form that is offered.
