1915 with AA 500 heads- now 2054

No that's just how the PP comes. I will take that off before installing in my car.

Finally pulled the engine to do the fly wheel and pressure plate swap. When i got the engine out, there was a little oil in the bellhousing. I can see that it came from the engine, but the seal doesn't look to have any damage. I'm almost wondering if it could be from crankcase pressure. Luckily my $300 RLR clutch disk was dry. My clutch also was chattering super bad. Oddly enough, everything looks pretty good to me, so I'm not sure what's going on in there. So now I'm waiting for a new rear main seal and oring for the fly wheel to come in the mail. I still haven't hooked up my 2 step switch because i am just not happy with anything i try on the floor near the pedal so i may try on the trans itself while the engine is out.
This was slipping at somewhere around 21-22 psi. I only dynoed to 20 psi on one run, but this must be somewhere around the 250hp at the wheel range. Hoping the new parts solve all the problems.

What does the disc look like?

[buguy]

Pretty much the same as it did when i put it in. Only thing i can think of is after the first time it slipped, i pulled it out and sand blasted it. Maybe i hit it too hard with the blaster? Maybe our sand is extra course?

I decided to give the CIP1 sintered iron disk a try. It was about half the price of the RLR. It is definitely different so who knows if it will work or not?! Haven't had a chance to put it in to test it yet but i hope to have it back in by the first of the week.
RLR takeout on the left, CIP1 on the right.

BG, I run a 4 puck in the sand. It is stronger/more sensitive than the 6 puck is but there are a couple things I have questions on.

One of the pix looks like the area of the flywheel that the disc rides on and it has been turned. The outer area where the PP mounts to that has markings on it and its surface looks older and maybe not turned to spec. Was this surface also turned when the clutch surface was machined as its relationship to the discs contact area (depth) is this contact distance very important to the clutch being able to apply full strength when the clutch is working.

Neither the 6-puck and even more so with the 4-puck is the slipping of the clutch is hard on things. A single full clutch pedal movement is very important when using either of these discs.

This is a very old problem with "stepped" flywheels.

For what it is worth.

That was a new chromoly flywheel, i didn't have it turned. I don't remember at all what it looked like when it was new. I drive this car in heavy traffic, so slipping the clutch is pretty much mandatory. But you are right, if i was a little quicker with the clutch release, it didn't chatter so much. Just almost impossible to do where i live.
I did buy a "new" German fly wheel turned by DPR. Also bought a new pressure plate. If there is any hint of chatter with the new stuff, it will come right back out and a new dual friction clutch will go back in. Even if it limits me to 18-20 psi of boost.

The new fly wheel appears to be very nice.

One advantage to being old is you usually don't have to deal with heavy morning and evening rush traffic (30 plus miles north or south which means you are lucky to go more than 5 mph so you, and the vehicle sit still a lot:).

The wife and I just bought a new car which is a hybrid; electric motor with a gas motor backup. It is taking some getting used to and some of the "updates" to how you do certain things or how you deal with them are stupid and in my opinion can/could be fricken dangerous!

I have to admit that we are saving a lot of $$$ on fuel though (up to $6 per gallon in places around here as I understand it). We take our first long distance trip (400 miles each way) in it next week and my backside is already puckering.

Your telling me! I drive a giant diesel truck. Not great for commuting!

[buguy]

Best breakaway i can get is 200 ft/lbs with a stage 2 and .060" shims. Hope the heat makes it grab better than that.

[John S.]

Your 2054 probably make 199lbs, your good.

[buguy]

It made 262 tq to the wheels at 20 psi. Ive already been to 30 psi but it slipped of course.

[John S.]

wow!
I was just trying to be funny. But, that’s a lot of torque. Must be insane to drive.

[buguy]

Only if i haven't driven it for a little while! After a bit you get used to it and want more.
