If it's a preset pressure plate, it will probably be "Acceptable". If it is an adjustable plate, you have to dial it in for street use and track use. It can become a time consuming task.

Yes. Have been since 2004. What have been the disadvantages of street driving with that clutch? I only go to the track a few times a year so if i need to adjust for on or off the track doesn't bother me. I have heard some people don't adjust and leave it the same pressure for both once they find a good pressure for there car does anyone have any input on that?

I have a McLeod Soflock set at 1200# and a Ram set for 1800#. That said the Ram 3 finger, 1800# base pressure with counter weights works better for the street, because of more base pressure.’
McLeod are not very helpful with setting up a soflok PP with heavier springs, as I had Hyatt Racing set one up for me. Also, the Soflok is 10.5” pressure Plate, and the Ram has 11” PP.
Overall, I like the Ram PP, and am using the McLeod Sintered Iron disc.
Mark Did you add the window?

Yes, you have to send the scatter shield in and have the window.
That's one of the disadvantages of the sintered iron disc. It needs to be adjusted. You also really need an adjustable pressure plate. When I stated using mine, I couldn't buy an adjustable plate, so I'd make 6-8 hard runs, pull the clutch and take it to a local friction house and have the pressure dropped.
I started at 1200 and ended up at 660 pounds with no counter weight.
I can't imagine needing 1800 pounds. Sounds like a parts breaker.
I update my clutch a few years ago. I now have an adjustable PP. On the street I use about 950 pounds of base and about 12 grams of CW to keep it from slipping. At the track, depending on conditions I start at about 500 and 10 grams of base and work from there.

At 1000 HP, you will need the 1800 lbs with the sintered Iron disc, or you will glaze the hell out of the surfaces on the street. I use the Ram Long PP and 11”
The GTX has about 680 HP, and that one I have 1200 lb, and does in fact slip some on take off on the street, and it is the McLeod Soflok which is 10.5”
Both PP are counterweighted, and for the track I adjust both down to about 200 - 250 lbs via the access hole on the bottom of the Bell.
Madscientist is right, if you try to launch on the track with 1200-1800 lbs, they will be parts breakers.
Tim Hyatt (RIP) told me that you need 1200-1800 lbs of base pressure for the street, otherwise you will glaze up the flywheel and PP surfaces. He told me that his son Chris runs the higher base pressure for the street, and it works great.
I am by no means an expert, and just followed Tim Hyatt’s advice since he was the premier expert with clutches for high HP cars. Oh, BTW, both of my cars are around 3500 lbs...so pretty heavy!

Can you use any disc or do you need something special? It uses a sintered iron disc.

Where did you send the bell housing for the machining of the access plate??

Where did you send the bell housing for the machining of the access plate?? Back to Lakewood. When I did mine it was 275.00 plus shipping.

I sent the Bellhousing to Hyatt Racing, as Lakewood did not want to do it.
Mark Is someone still working at Hyatt?

As of the middle of last year, Chris was still adding windows and certifying bell housings. Pretty sure he is still doing clutch work, too.
