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 …

Why not duplicate the cereal bowl flange as a plate, and install from the inside (under dash) of the car? Much cleaner, without the "bolt-on" look.
What a Face

Spacing might be an issue. I'll verify this weekend.

I Think it is a waste of time. No matter how many plates you stack, your firewall sheetmetal is not going to be any thicker/stronger. I'm not 100% sure that a duplicated plate will bolt right to the back side, but if someone wants an extra. We can offer one. According to Cloak, the firewall at the Clutch is a flexfest too. I've got something for that nonsense.

Ya I tore through my firewall at the clutch. 1/16" plate steel welded in took care of that though.

Clutch MC size

Post  xschop on Fri Nov 13, 2009 10:46 am

Has anyone put on another Clutch MC.....
You know we are sticking in C5 clutches ....maybe a C5 Clutch MC to match the LS pressure plate finger tine forces?

The Tilton/Wilwood shorties got my brain cells woke.... 944 kit would be possible

Not so much that, but...no space.
Take a look...

Pedal support interference inside...





And a lack of real estate on the outside...



'87 parts car / (off-topic...clutch spring that needs to be removed)



Reinforcements will need to be added in the engine compartment, but 1 common plate should be feasible...and include correct master cylinder (brake and clutch) mounting positions.

Tilton MC sizing

Has anyone asked Tilton about sizing for the Turbo S calipers?
Also, who has the best pricing/service on Tilton products?
Thanks,

I went to their site and filled out a form. The more information you have the better they can guide you. Responsive too, I got answers back the same day.

'87 UP 944S / S2

Front Caliper Pistons = 2 X 40MM, 2 X 36MM
Rear Caliper Pistons = 2 X 30MM, 2 X 28MM
Front Rotor = 304 X 30.6MM (*S2 = 298 X 26.6MM)
Rear Rotor = 299 X 24MM

This info is what Tilton needs...*from the email form:
(Specs for the 944S / S2)
Vehicle Info

Make: Porsche
Model: 944S

Front Brake Information

Number of pistons within each front caliper: 4
Are pistons on one side or both sides of caliper: both

Diameter of pistons on one side of caliper (list all):

Piston 1: 40 mm
Piston 2: 40 mm
Piston 3: 36 mm
Piston 4: 36 mm
Front rotor diameter: 304 mm / 298 mm (S2)

Rear Brake Information

Number of pistons within each rear caliper: 4
Are pistons on one side or both sides of caliper: both

Diameter of pistons on one side of caliper (list all):

Piston 1: 30 mm
Piston 2: 28 mm
Piston 3: 30 mm
Piston 4: 28 mm
Rear rotor diameter: 299 mm

General Information

What is the motion ratio of your brake pedal (5.5:1, 6.2:1, etc)? 6:1 (7.6:1 if relocated pivot +1.1")
OR
If using a Tilton pedal assembly, please provide part number: 72-650
Vehicle weight (with driver and fuel): 3000 pounds
Vehicle Weight Distribution (with driver and fuel): 1650 / 1350
Vehicle wheelbase: 94.5 in.
Front tire diameter (outer): 24 in
Rear tire diameter (outer): 25 in
What is the vehicle being used for (street, road racing, circle track, drag,
etc)?: street, some road racing
You will get a response something like this...
The numbers show that 5/8" front and 15/16" front will work for a
lighter pedal (street and some track) and that 7/10" front with 1" rear
would work for a harder pedal (pure road race). Most people who drive on
the street as well prefer a little lighter pedal. The trade-off is a little
extra pedal stroke.

Results are not guaranteed since calculations require estimates for
the vehicle center of gravity height, tire grip, brake pad friction
coefficient, how hard this particular driver prefers to push on the pedal,
and other factors.

Mike O'Neil

Tiltons on track car

Post  968gene on Fri Nov 27, 2009 6:08 am

Thanks for the info GT. I filled out an information sheet and sent it off as well. My car will be around 2,700 lbs and the from rotors are 322mm in diameter (not to mention its a full race car and not street driven). I'll post the results when I get them.

No problem...

The Tilton dual MC setup is by far the best manual setup, if for adjustability alone...
I talked to Mike on the phone ~ 3 (?) months ago.
Lots of help, and he (also) strongly suggested against the stock pedal ratio.

(Move the pushrod pivot point up 1.1" for the best results...this yields a 7.6:1 pedal ratio.)

Every setup will have it's own "special features"...
The form makes setup easy.

72-650 has been axed...

Post  gt1scca on Tue Dec 29, 2009 9:20 pm

Tilton has discontinued the 72-650.

It has been replaced by the 72-610, which is a 90 degree mount to begin with. I have looked at the specs on the 72-610, and there should be enough clearance between the MCs if they are used with remote reservoirs.

Some vendors have remaining stock of the 72-650, but those who have sold out are replacing them with the 72-610.

We wanted a 90 degree mount, we got it.

So the 72-610 will bolt right up to the single MC plate, or will we need another plate?

Yes, same mounting dimensions as 72-650.

Also, for about $30 more, the Wilwood 60 degree is still being produced. Sorry Tilton, but Wilwood also uses the same mounting location (for those who prefer brand consistency).

Wilwood 340-4630

I'm gonna quote myself here, so everyone will have the MC sizing info.
There are other applications, different setups, etc.

Mike (@ Tilton) must be out for the Holidays, so I am sharing the info I have for the stock Turbo / S setup.

FRT. MC = 5/8"
R. MC = 13/16"

1986 944T (My Setup...)
FRT. MC = 3/4"
R. MC = 1.0"

(*I don't mind a heavier pedal, as I will be tracking & autocrossing my car...)

Whatever became of this, I'm wanting to go back to manual brakes. Not because the BMW system doesn't work but for the simplicity of it. Who sells the adapter plate and pushrod (or if nobody sells it are there diagrams)? What size did you guys decide will work (I have the LS430 fronts and stock 83 n/a rears)? Where didja get the tube's, flareing tools, and fittings to make them? Thanks in advance.

Been trying to call to talk with tech support at Pegasus. I have seen 2 other website threads (BMW) that got the tubing end confused. Our 944's have what is referred to as "Bubble Flares" which are CONVEX and require a CONCAVE seat.......I have the premade line from Southwest Speed (one is 1/8npt to 4AN) the rear circuit I have a 1/8NPT spilt to 4AN Tee. Also have 2ea 4AN to 4AN lines for those...

I figure I just need 3 of these and it is all 100% bolt-on....

The part 3265-19 from Pegasus are the ticket...You'll need 3 ea.

Southwest speed..... 1ea for the rear circuit (skips the 18NPT adapter to 4an)

http://www.southwestspeed.com/?sec=view_part&id=1203

Also 2 lines each for the front circuits with 90deg ports too.....

http://www.southwestspeed.com/?sec=view_part&id=1213

And 1ea spliter right off the front MC circuit.....1/8NPT to double ended 4AN....

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=380208969772&viewitem=&sspagename=STRK%3AMEWNX%3AIT


ALL 100% BOLT-on....Don't forget to clean the oxidation off the Bubble flare with a wire brush or emory cloth.... Very Happy

Check your Manual, Tim...

Early 944 N/A rear caliper pistons are 36MM (X1 each side).
Rear rotors are 289MM Dia. X 20MM thick.
LS430s are 42MM (X4 each side).

Pedal ratio (+3/4" pivot @ pedal) should be 6:1.
