HOW TO DO AN ADVANCED SEARCH.
Mon Jul 08, 2013 3:56 pm by Admin
For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.
When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).
After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Firewall Cracking
Firewall cracking is a known 924-944-968 issue. You may want to think about this while you have the firewall stripped.

Yup had to weld 1/16" plate steel over my firewall where the clutch/master went in. I did my Hulk impression and tore the clutch master out of the firewall while driving it one day.968gene wrote:Firewall cracking is a known 924-944-968 issue.

Did you simply stick on the stock MC with a custom pushrod?
I would think going to dual MC's would alleviate the stress. I am using 1/4" thick wall plate with 1.5" washers on the back side.

It wasn't the brake side that tore, although I did beef that up also, the clutch master is what went through. I have power brakes so I don't believe I have as much stress as a manual setup (dual or not).

Re: Tilton Dual MC Setup
I don't foresee any problem. The far driver's side bolt may take more pressure than the opposite side bolt by default, but the thickness of the plate distributes the forces to all 3 bolts almost equally.
Do you have pics of what you did?
Shortly, I will be making the custom plates and pushrods for the stock MC to bolt to the Cereal bowl also.

Friggin ay
6 hours dismantling, drilling the clevis relocation 1" higher and then doing some drawings for the best set-up on the push rod conversion piece needed.
I don't EVER want to tear out that brake pedal and try reinstalling that friggin' return spring again. What a PITA.
O.K., gripe dept. closed....
There are a few different ways of doing the pushrod, but whichever way you want to do it, I had mic'd out that the Tilton 72-650 heim center to 944 pedal pushrod clevis center should be exactly 125mm from each other for the Tilton assembly to be in relaxed position and clear the firewall. Also my Wilwood MC pushrods had to be trimmed down 1/2" to attach properly in their relaxed positions.
Heres what the pushrod should look like for the easiest swap. Keep in mind that for optimum adjustment the Tilton 3/8 x 24 Male Heim that comes with the Dual MC Housing assembly should have it's centerbore (+ or -) 1/8" from the firewall sheet metal......
This will put you right on the money with some forward and aft adjustment. Which got me thinking since these cars are all "hand made"...How far off if any, are the brake mounting bracket points from car to car....

For those of us running stock turbo brakes.
I emailed Tilton and they suggested a front MC of 5/8" and rear 13/16" for a 1987 944 turbo setup.

Re: Tilton Dual MC Setup
originally I was told 5/8" front for the 4x42 lexus calps and 1" for the lexus 4x42 calps in the rear. Now I have been told to put 7/10" on the same front lexus 4x42 calps and 1" rear for the RX7 3x36mm calps....
"to keep it balanced".....
Also as per experience. Tilton does not supply the nuts that bolt the Ind. cylinders to the 72-650 housing. I measured them to be 3/8 x 24 and you will need 4 of them with lockwashers....FYI
LT1 said....... "2 for each front and 1 for both rears"
Let me get this straight.... So the long tube coming out of the top firewall closest to fender is the one for the rear brakes and the other 2 are for left and right front caliper feeds and they need to be tied together?

Re: Tilton Dual MC Setup
The rear line and front right lines are both routed from the master together through the firewall, in between the heater housing and firewall to the right side of the car, through the firewall again, into the front right wheel-well where the front right line connects to the front right brake hose while the rear line goes under the car and back to the rear to a distribution block.

I didn't use the dual m/c obviously, but Autozone or any auto parts store sells brass T's. Just used one of those...

Ohh Ohh, I bought a T from a 80's BMW 5 series out of pick-n-pull.

Complete Bolt-On is finalized
Final billet housing and firewall plate pre-heated then Tig-welded with 1/2" welds because of the thick billet used. I made the pushrods out of 4130 steel. Everything bolts right up and will take a ton of force...Literally...
I only have 1 set unaccounted for and will only make these in runs of 3 or more...

As soon as the Polyurethane bushings show up I will assemble your set. What color is your car again, you want them in Krylon Blue LOL...... I like the Krylon Yellow, cheap bling-bling and looks good with black and billet.
I ordered the plate for the simple MC pushrod conversion kit. I need to get a heads-up on that now that you remind me....

Got my mount in today
It is a very nice piece of work. The welds are perfect like a roll of nickles. It seems like I saw it somewhere but now I can't find it, what hardware should I use to mount it to the firewall?

3 bolts
2 bolts........5/16" x 1" long
1 bolt.........5/16" x 1.5" long Goes thru thickest part of plate and housing.
and washers behind firewall is a must, might as well throw on 3 lockwashers up front.
Don't forget the stock pedal clevis to Tilton Heim centers should be 125mm C2C. It is easiest to install the pushrod setup on the Tilton hosing, then go under the floorboard and run your clevis pin through after you have drilled your pedal upwards 1 to 1.1". I had to trim the Willwood MC pushrods down exactly .5" and everything bolted up like it came from the factory. Maybe Tilton MC' Pushrods are shorter, I'm not sure, just make sure the individual MC's are setting flat on the 72-650 housing and their respective pushrods are in their relaxed position....
For everyone asking, I am building more of these this week and will have them ready by the end of next week after my trusted welder does his magic....Please respond to http://www.944v8s.com/Products.html
I do not expect to have more than a 2-week lead time on anything offered on the new site....Xschop

Re: Tilton Dual MC Setup
If you previously had the stock 944 MC on the cereal bowl and you have already fatigued your firewall sheetmetal....here's an idea for you. Later I will modify this setup to adapt to the WILWOOD 260-7563 MANUAL MASTER CYLINDER CONVERSION PLATE & PUSHROD.....http://www.944v8s.com/Products.html
As for now, I think it would be overkill for the Tilton Dual MC Setup, but here's a look at what I will make...
Double adjustable heim joints with tension preload. This will fix any firewall flex problems....
