Bentley Turbo R Track Car!
Discussion
I'm absolutely loving this build, excellent work!
I would say rather than mess about with water cooling, what you really need are some PROPER brake pads.
Something like the Carbotech XP10 or 12, they would be able to make them up using your old trashed ones as a template. It could make all the difference and save the weight/complexity of water cooling etc. worth having a chat with them either way, they were very helpful when I was on the look out for some serious brake pads.
Good luck!

You can see the various compounds there, I'd guess one of the higher temperature range ones would be the place to look...

Re: brakes.
A bit of a physics lesson. How do brakes work? They convert the energy into heat. So, pad compound only varies the wear and fade point. My 1144's work briliantly on the road with no squealing - did fit anti-squeal backing though. A lot of brake squeal is caused by the high frequency vibrations causing the calliper piston to rotate on the back of the pad. Hence why you tend to only hear squeal on light braking as under heavy braking the piston is trapped and cannot turn. Anti squeal coating helps by bothe preventing said rotation or at least letting it do so quietly. Bigger brakes - common mistake is to assume that bigger discs have more "leverage" than smaller ones. Partly true, but it is the speed of the disc through the pads that gives the increase. Still lots of heat though with 2000kg behind it..... still will need the water cooling I think. These "facts" are from my experience in the businees and from being involved with the manufacture of brake callipers. Please offer your oppinions, but let's not get bogged down again,huh?
Anyway. The 30lt water tank will be here this week and I will also use it for the winscreen washers, which means I can remove the 10lt + tank from under the n/s/f wing. Less weight and more air to the brake. Then i will need to modify the airbox on the o/s so there will be the same increase of airflow.
Later I will be fitting some 380mm discs and twin 4 pot callipers (per side) which is better than he 280mm fitted plus twin M16 pig iron callipers.
Going to measure up for the plastic windows this week too and remove some more trim. Looking at a race battery to save about 15kg too. The present fuel tank is 110lt and steel, so a plastic fuel cell should also save a bit - have I repeated myself here? Dunno. Old age plus a large Malt won't have helped. Should have the 305/30.19 tyres this week too.
Got pulled by the BiB on the way to the PHSS today. Didn't like the rear bumper! Rectification notice etc. Also went on about its MoT wothiness and the lack of door cards "sharp edges" eh? Nothing in the C&U regs about that. What do you want in an accident, some metal panels or sharp wood splinters from the original wood trim? Paul Mk2 24v might like to comment on this?
He was quite proud that his unmarked car has been identified on PH - thought I would know about it!!!
Lastly, I have seen a proper BGW for the car (Big Gay Wing), much wider, much higher, much more upsetting for some. Hopefully.
Good to talk to the dozens of well-wishers today. Thanks.

Sooo, after the Motorpunk track day at Blyton Park a few things needed to be sorted.
Managed to smoke all 4 tyres, so adaptors from Superforma to allow Porsche 19" wheels with 275 section tyres to be fitted.
Old wheels and tyres.

Well, what can I say? Featured on the homepage. Life is now complete!
I will post some details very soon.
Since I last posted, here is a quick list of further work.
Plastic rear and side windows
OZ wheels with Federal track tyres.
Water cooling for the brakes.
Tillet (Caterham!)seats - anyone want some Bride seats?
To come.
Carbon fibre (really!) roof comes next week. That should save 20+Kg from upon high...
Alloy petrol tank.
New conventional suspension.
New gearbox - last one borked at Castle Combe trackday...
Large, no, 'kin large cooler for the above....
Remove dash and hevac. Nice small hevac to go in, so still have heat and a/c.
Power steering adjuster for a bit more "feel"
Controller for the gearbox to give manual change of the autobox.
More power needed, of course. Flat out @ 140mph at Goodwood and needing more!!
Find some lightweight outer door handles. You may titter, but they are SOLID brass!!
So aiming for about 17/1800 kg and eventually 600bhp.
I will post some pics for you soon.
Now registered as B8 FOU - proper!

OP, just saw this thread again and as before it made me smile!
The whole car is fantastic and bonkers at the same time - marvellous!
Was lucky enough to see the monster up close at the July Surrey meet organised by ironictwist but sadly you weren't around.
It just has to be seen to be believed.

I followed this car around Blyton park earlier in the year in my MX-5...watching the water cooled brakes at work was fantastic, not sure how much water it got through but it was always being topped up!
Ditto, in fact the MotorPunk days are the only ones I've been on where you can have no desire to pass "slower" cars, or can't wait to be passed by the faster cars simply 'cos you're enjoying seeing them.Gassing Station | Readers' Cars | Top of Page | What's New | My Stuff
