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 …

Chart
I think V8carrera over on Gestapoville posted up the different MC bores from the various 944's
Anybody got that chart.

Re: Tilton Dual MC Setup
"The shiznit..." and $10 cheaper...Also, I'll copy the MC info over here...
The LS430 4 x 42mm pistons have slightly more (8sq. mm) than the 996 / GT3 (Big Reds). The GT3 master cylinder has a 25.4mm (1.0") front circuit bore. The GT3 rear piston surface area comes in at 116sq. mm, the SAME as the FRONT 944 Turbo (which may be moved to the rear).
NOW...the GT3 rear MC circuit uses a 25.4mm (1.0") bore, BUT the 944T front circuit is supplied by a meager .75" piston bore.
I would use a 1" bore MC for the front, and a .75" bore MC on the rear circuit.
Here's the chart...

Got it on it's way from Southwest Speed ($157)
I think the MC bolt spacing is universal for many brands of MC's

ls430 rears?
WHY NOT?
Be major overkill.... but 1/3 the price of front Turbo's moved to the rear

Re: Tilton Dual MC Setup
Got specs / piston sizes / rotors ? for the rear LS430? If so, we can size the rear master, stick a fork in this pig and call it a day...

Re: Tilton Dual MC Setup
I was actually thinking the same Front LS430 calipers on the rear of the 944.
But now that you mention it, I will look into the rear LS430 specs, They are Dual piston 2 x 42mm.......Do remember, they are half $ what the front LS430's were running.....
I wonder what rear rotor we would have to go with?

Re: Tilton Dual MC Setup
Yea, NO. The front turbo brakes are trackable on a turbo car with some quality pads...they should be awesome on the rear. The Big Reds kits use them on the rear with nary a peep.
If you don't have a turbo car to begin with, disregard the above comments...BUT, the LS430 rears are freakin' monstaaazzz!
very, very

Monstazz
Looks like the LS430 rear 2x42 calipers are about the same $ as the front 4x42mm calps!!!
if we stick the 4x42mm on the rear of the 944 NA, will the 87-up Turbo rear 300mm rotors fit the NA's. This info I don't know.....Holla Back Yo

The Schiznit
Setting the pushrod directly in center while mounting Dual MC housing on it's side puts the master cylinders over almost an inch away from the valve cover.....
Bracket design to mount to firewall will be a joke....
And the smooth operator that makes the pushrod setup hassle-free (hopefully) is the Heim-joint connection on the 1:1 cam design with built-in balance bar (set in with pillow ball joint in center)....

rear rotor choice
The 87-up Turbo rears are all 299mm wide and all 100mm offset according to Brembo.

For the 1986 Turbo, 300mm X 74mm, front and rear.
The rears have an integral concentric ring with an outside dia. of 71.75mm...

MC sizing...
When sizing master cylinders for the Tilton dual MC setup, pedal ratio is a major part of the equation. I had thought the 944 stock ratio was 5:1...until I got the dims from an actual pedal.
Here's the results...
The stock MC pushrod location = 4.25:1 ratio.
The .75" higher modified location (used in the booster delete / single manual MC setup) = 6:1 ratio.
.

Tilton Dual Housing for 944
Got alot of R&D time in on this one. I will be machining these from T-6061 and then Tig welding to the 1/4" billet plates I traced from the cereal bowl.
The 5/16" diameter hole bolts directly to the driver's side bolt hole on the firewall. Depending on the Hooker 2312 headers Johnny Johnny modded up, the bolt hole can be drilled upwards if need with this design to allow for more clearance. The Heim joint on the Dual MC bracket allows for this without any pushrod binding....

Re: Tilton Dual MC Setup
so this bracket will be welded to a plate that bolts to the fire wall, we just get the tilton bracket, master cylinders and remote reservoir stuff?
I take it there will be an alternate MC suggestion for those with 951 rear calipers

I have an economical solution....Get your ass out of the car, pop the hood and turn the knob supplied with the Tilton Bracket. With this design the knob is right there up top

Re: Tilton Dual MC Setup
the markup is incredible, I wonder if they tack the word 'billet' on there if theyll raise the price for me. why would you need to adjust the bias from inside the car anyway?

False advertising
Tilton couldn't mark their Dual MC housings "Billet" because they are made from cast aluminum. I made the firewall plates from 1/4" Billet t-6061 and will make the bracket holders from the same alloy to get the correct welding properties and strength from an all 1/4" design. Will save a few pounds compared to steel material.

Re: Tilton Dual MC Setup
oh, I was talking about the remote adjuster =P
any thoughts on sealing the hole around the push rod, lots of funky gasses in that area of the engine bay... how is this normally done without the brake booster?
