Single Master Cylinder Conversion kit

How would this setup compare with the dual MC setup mentioned elsewhere on the site?

The Wilwood 260-7563 is the closest match to the 944 master cylinder, and is a designated "manual" master cylinder. This one fact means the Wilwood will require less pedal pressure to stop the car than the "power-assisted" stock 944 MC. The Tilton Dual MC setup is matched to the caliper pistons and rotor surface area. The Dual MC setup requires 80-90 lbs. pedal pressure...the Wilwood I am unsure of, but the 944 stock MC requires ~150 lbs. pedal pressure.

The Wilwood is the "cost-effective" solution, but the Tilton is THE BEST setup for manual brakes (at a price, of course...).

The stock 944 MC is not a good idea...ask expuppy.

What he said

BTW,
Wilwood's installation kit is NOT required now...

Well, I am looking to get the car up and running in a safe manner first. I may end up with the dual MC setup later on, but it looks like the single shouldn't be a problem to start with. As mentioned in the manual, if the track guys are running a proper single MC setup, then the setup should be okay.

I also notice mention of the proportioning valves. Do I need to change mine out (86 951) for this setup?

If you have a place to setup / test the car, an adjustable prop valve would be ideal. If not, the Turbo, S or 928 valve will work (5/18 bar / #951.355.305.01).

(I'm even quoting the manual...mine's open on page 79...beats searching for part numbers on 5 different drives and a dozen or so sites!)

NOTE: The Booster Delete Plate shown on page 78 is ONLY for the 944 MC, and retains the cereal bowl. Revisions to the manual will be posted shortly...)

Just to be clear, can I use the Wilwood 260-7563 set up with the LS430 front calipers / turbos rear?

Greg?
I'm not sure what Expuppy was running as far as calps on his. I would think with an adjustable biasing valve set on the rear circuits..... many possibilities

Yes.
5/18 Porsche 944 OR Wilwood adjustable.

With any brake setup.

(expuppy is running Wilwood fronts, Turbo rears (?)
and a Wilwood adjustable prop valve.)

Good to know. Got my plate / rod on order through Greg. I will be working on rest of the brake stuff once I get through buying all of the engine swap stuff.

Here's the Wilwood master cylinder...

For everyone looking into this setup, I am also building more of these this week and will have them ready by the end of next week.............Please respond to [You must be registered and logged in to see this link.]
I do not expect to have more than a 2-week lead time on anything offered on the new site......Xschop

Check pm

i was wondering if have finished the plates yet?

Hold your horses Homer. I will be in the shop the entire week and will square you away. I'm doing all the Willwood plates first...Read your Swap manual already.....The 944 MC is not as good as choice as the Wilwood single MC because after a while your firewall will be screemin' for Willy, that's if you don't frag it out using the Stock MC.

If you are going to be getting a plate to begin with, you should do yourself and upgrade to the Wilwood MC. It's only ~$130.00, so it's not like it's expensive, and the MC has to come off anyways. There is a good chance the MC is still OEM 20+ years old. Get a new one. Be safe than sorry and do it correctly the first time.

thing is sweet

Yeah modenas, you'll snap your knee-cap befor you snap this plate.... 1/4" T-6061 T6511 and 4130 heat treated steel pushrod. HEHE
I'll post some pics shortly, The 944 master has an 0-ring and I adjusted the diameter so you can reuse it even. From what I see the coil packs on the truck 5.3 clear by 1/2". I can't say for the LS coil packs.

how many did you make?

Hey Modenas, stick your 944 MC up in the firewall location to see if they are "Dragula" compliant....

i bet so even with my headers

Because of housing diameter size differences in the plate, you can go fom the Wilwood to the 944 MC, but not the other way around unless you have a large gap and compromised plate strength because of the mounting hole spreadwidth differences......
