First Ford GTTT (Twin Turbo)

Hoses come in different materials. Placement of solid and flexible line has an effect also.
As I stated before the idea is to get rid of the heat as much as possible before it gets that far.
You see red hot discs quite often but it's not very often you see a red hot caliper.
Anyway back to GTTT silliness.

That's what I love about the English, not ashamed to discuss their frilly knickers in public.

with the risk of an oftopic
i will make a nother question

i read on somebodys thread about braking fluid starting to boil in the brake caliper and ruber parts starting to melt because of the high temps created by the rotor and pads
my question is: how does the fluid and ruber parts stay togeder in cars that race at lemans(i can see the red hot rotors at night)

????

How often do you see the red rotors when the cars are going out of the corner?

By then the cooling ducts and systems have cooled the rotors enough for then not to glow any more. If it can do this in 50 yards around a corner at relatively low speed imagine how much cooler they will be after a high speed run down a straight!

As Tim says it is all about getting rid of the heat before the parts get too hot

now i realy realise how stupid my statement was

back on topic
i read post about the issues you have with the gearboxes, because of the power produced by the engine, is the ford gt box so over-engeneered, to suport double the Hp?

[EDIT] now that i think about, i have never seen a red rotor at the end of the corner (not glowing)

It was certainly not a stupid question. Most people give far too little thought to brakes.

There's a lot more to this subject - insulating properties of the pad, water cooled calipers etc, but the basic idea is as stated.

I'm sure there must be a web page somewhere that would go in-depth on this subject but I can't find one. Maybe someone else could point to one?

I dont know much about the GT 'box but I think it's been discussed here somewhere before. Try searching the forum.

I wonder how they've dealt with cooling on these 800+ bhp turbo' GT setups?
Maybe it won't be a problem because they will never see wide open throttle for more than a few seconds with big breaks in between. That's what usually happens on dyno's and drag strips isn't it?
Yeah ok so I'm circuit biased.

This is how I do it - Coke cooling. -

The GT40 Clubs over here visted Ascari last year. www.Ascari.net

The tour guide said they had been trialing the Recardo Box (As found in the Ford GT) for their car but it gave problems and started "making a lot of noise" after about 20000km They claim about 500 hp out of the BMW units they use.

So I would presume the box will not last too long!

They use a different box but for the life of me I cannot remember the manufacturer but it is also used in a load of other high end mid engine applications - they did say that the box was too long for use in GT40 replicas.
