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 …

I won a Tilton dual mount and 2 master cylinders for about $100, got to love Ebay. If anyone is looking someone is selling a NIB wilwood dual mount for $129.

What's the Wilwood mount part# ?
I just finished re-milling these last 2 firewall housings for the Tilton 72-610 (72-650 obsolete). I also had them welded where there is more left to right adjustment with washers between the bracket and dual mount because these firewalls to pedals are off from each other it seams....damn Germans.

That looks to be a copy of Tilton's 72-650. So it will fit the Dual mount that I designed. I had to machine off 1/2" from the end of the firewall housing mount because the available 72-610 has two of the stud bosses protruding unlike the 72-650. Looks like that Wilwood also doesn't have the stud protrusions because it is 60* as well (it would mount up)

If anyone is planning on buying one of your mounts they need to snatch this. It is the cheapest I could find.

I had enough material to make another one and had it Tig welded. So these are the last 2 period. $225 shipped in the U.S. only. Sorry. My Gov't has made it miserable to ship outside the U.S. LOL
That inexpensive Ebay Wilwood mount will fit now just like the Tilton 72-610..... And of course if you can still find a Tilton 72-650 it will still bolt right up. I left enough material where you can drill a 10mm hole for a heim joint brace like I did on mine also.....

I have 1 last Dual MC housing left. I will not make any more of these style. $215 shipped anywhere in the U.S. This will include the custom pushrod that screws right onto the 944 brake clevis....Just PM

Finished M/Cs and Hydraulics

Post  87-944S on Sun Jan 02, 2011 6:44 pm

Well, I'm back at working on the car, I bought a propane heater that heats up my tiny garage rather quickly. Here's some pics of the finished plumbing for the brake and clutch M/Cs. The empty reservoir is for the rear brakes, I'll do those soon.











And the speed bleeder for the clutch



The rear brake SS braided line will go into the interior to an adjustable bias valve mounted under the dash.

You are running truck coils, right? I tried to mount mine with regular LS1 coils and the coils would have to be relocated.

Yes, those are the truck coils, they mount a bit further up on the valve cover.

Reviving this excellent thread...

Post  ausgeflippt951 on Mon Nov 02, 2015 5:16 pm

Ok, I'm 100% convinced -- to hell with the Hydroboost, I'm goin' dual masters.

After 4+ years of living with the dual masters, how do you guys like them, and what is the consensus on proper sizing?


My track car is technically streetable (and still street legal), but I'll sacrifice streetability for a rock-hard pedal feel.  Currently has stock '86 951 brakes front and rear with PFC 11/08's as the pads.


It looks like the Tilton remote MC mount is NLA, but the corresponding 60-degree unit from Wilwood still is (click here).  

Likewise, Tilton seems to have superseded the 72-series MC's with the 75-series (click here).



I plan to relocate the brake clevis pivot point up 0.75" (rather than the 1.1").  

For '86T brakes, it looks like I want a 3/4" front MC and a 1.0" rear MC.  Can anyone confirm?  Especially with any real-world experience?


And can anyone confirm the MC's and Wilwood mount I've cited above are what I'm looking for?

I have dual masters and have DD my car for about three years now. The clevis is drilled up .75in. 5/8F and 7/10R MCs on stock 87 turbo brakes.

The system works well. I have let several people drive the car and none have complained about lack of brake or the feel. My wife drives it with no issues. One of my friends is a former GT 1 national champion driver and he drove the hell out of it. He thought the brakes and brake bias were spot on.

That said a couple of points. The lower MC gets overheated after sitting over a hot engine if the car is not moving resulting in a spongy pedal for a short time until it cools. I keep meaning to make a heat shield for it.
The pedal is firm and it sits a little high. The height could be adjusted, the rear MC could be changed to a 5/8" to soften the pedal. I went through several MC's to arrive at the system I have.

I think my system is very good as it is, but, the Porsche factory MC with the adapter for the Ford hydroboost would be the way to go. That system would offer a factory feeling brake pedal while keeping the proportion valve. It would not get the heat sink issue as the fluid circulates to cool.

Great feedback, thanks. Main reason I would like to go with the dual masters is because I have manual steering and do not want another accessory (or PS fluid) to deal with. Plus, I want the ability to tune brake bias depending on the track.

Have you had a chance to take your car on track? Curious how it changed by taking it on track.

No track time, mine is my daily driver. I have manual steering, also. Same thought process to keep it simple. You could still run a power steering pump just for the hydroboost, there is someone here that did it.

Yeah, I thought about it -- but it's almost as if I am opposed on principle to having power steering fluid on my car. Perhaps it's PTSD from owning the crap 944 PS pump for so many years; once I went to a manual rack I have never looked back.

How would you say your pedal feel compares to that of a stock 87+ (not '86, since the booster was different) 951 brakes?

Mine is track only. Started with DMC, then hydroboost, and now back to DMC (which works better for me). It is much easier to modulate brake pressure with DMC. The only issue, you have to push harder, making it important that you get the ball of your food on the brake pedal.

Thanks Tim. What's your brake setup on your car, and which MC's did you wind up with?

I don't mind having to push harder. I just spent last weekend racing a buddy's Cayman S race car with manual brakes...

Every time I think about changing to a power steering rack and hydroboost I read about someone's leaking PS rack. I don't even notice my manual rack and manual brakes. My wife drives the car with no issues or complaints, other than no A/C in the summer.

The effort with my brakes is not bad, more firm than power brakes but not bad enough to be noticeable. No one that has driven it thought they required too much effort. I asked. I never drove the car prior to building it so I can't compare to the stock brakes.

Yeah, I think I may go juust a touch bigger than what you went with. Here's my logic: with only 1.1" of travel in those dinky little master cylinders, there isn't much room to play with. You mentioned the feel is similar to stock power brakes, albeit a bit firmer; I'm wondering whether you'd find yourself being able to bottom them out if you really stomped on them?


As an amusing aside, my wife just took her Professional Engineering license exam on Friday. I mentioned to her that I really just need to do the math myself and see what the numbers say but I haven't yet gotten around to it. She responded that since she is feeling inspired by her PE exam, she'll do the math for me!

What a gal.

Knock on wood here, but I've never had an issue with my power steering or hydroboost setup. Now that I've got it paired to the 951 MC I think that it'll really be the best setup...

Good data point, thanks. Looking more and more like I want to go with 5/8" F cylinder.

What motion ratio on the pedal did you go with -- moving .75" up?

I moved mine .75in up. 1in may be better as it would give you more pedal travel for heel/toe on the track. Manual brakes don't have much pedal travel.
