Has anybody actually connected up the brake ducting holes in the front of the 400/450SE front air dam to help cool the front brakes?.

Also has anybody tried making an air cooling system for the rears?. I heard some time ago that Tower View Racing were messing around with some sort of under car 'air scoop' to direct some air to help cool the rears. Anybody done this?

I have a couple of photos from previous owners of my 390 wearing front ducts. I think the radiator must have then been replaced with a wider one because it obstructs the holes in the air dam.

I've used them to run some trunking for a cold air feed to the air filter.

I think Steve Heath might not be too pleased at that description, because I think you're referring to the scoops on the back of his 520. I'm pretty sure they're for brake cooling, either that or collecting the grass cuttings ...

Mine has trunking connected to rear of holes. Trunking is routed around nearside of engine and then connects into heater/venting system - for fresh air supply.
Sounds like yours isn't like this mike. How does yours get air feed into the heater?

I assume mine is factory fitment (late model like yours - May 1991)

For road use the front discs should cope ok - they are nice and thick to help dissipate the heat.

But for race track, ducting would be good!

You obviously ain't been on one of us Welsh boy's 'Chicken runs' around the Brecon Beacon national park.....

I remember Tower view muttering something about fitting air scoops under the car to feed the rear brakes.

The ones on the front are just left open and don't go anywhere.

On mine they have plastic ducting to supply fresh air to the cabin vent system - have also like Paul used one of them as an air feed to the filter.

Unless you insulate them they pick up so much heat from the engine bay they only provide hot fresh air to the cabin anyway - no good for where I am but I suppose it helps demisting.

Mine run off the front inlet, out through the wheel arch and then back into the engine bay. Sugest you could manufacture a backing plate to the discs with a flange to accept the ducting - would have to be pretty good quality ducting though not to split with the constant turning it would endure.

correct Mike. The ducting to the rears on mine just come from intake 'scoops' under the car and not from the front holes. Don't know whether Steve ducts to the front too.
The rear ducting certainly prolongs the life of the rear pads on trackdays.

I spoke to a local garage that deals in racing E type jags,same rear axle setup. They said the big problem on long races id getting rid of the hot air. Hence the e types with holes in the boot to let the air escape.
I think the wedge will have the same problem. So you may have to duct the hot air away as well as duct in cold air.

The E type Jag used to have under body air scoops feeding the inboard brakes with cold air.
