front air scoops

New member
I noticed in 911 & Porsche world that the red sc had front air scoops to keep air running to the front brakes.

does anybody know where these are sold?
 
Yeah I wondered about those myself as I wasn't convinced by the description in the article. In Wayne Dempsey's 101 Projects for 911 book those scoops are shown somewhere, but are described as air ducts to feed the wheel arch mounted oil cooler - sounds rather more likely to me - you would only have one on the LHS (as you look from the front), I didn't notice if there was also one fitted on teh RHS. That's not to say that someone enterprising couldn't fabricate suitable ducting etc to get the air to the brake discs, but it would probably require a fair bit of jiggery pokery (technical term !)
Any brake duct kits that I have seen for the 3.2 tend to be scoops that pick up airflow under the front A-arms and fire it into the centre of the disc eg. 9M sell a kit that does this. Alternativley you can tie wrap the 993 type air deflectors to the leading edge of the A-arms (Richard Bernau has these IIRC).
This doesn't actually answer your original question of where the ducts are available from, but I would guess www.pelicanparts.com in the US would be a place to start.

I have seen a car with one which was to help cool the oil cooler,it replaced the small black overider next to the indicator!!
 
Try

http://www.demon-tweeks.co.uk/

they seem to be called 'Bumper Mounted Brake Duct Inlet', but there is no picture.

Thought about them on my car, but decided that they were just a bit ugly, so fitted scoops/piping to the underside of part of the front suspension (the bit that goes horizontally from the body to the wheel - no, not the track rod ends !).
 
The article is misleading (I plan to email Chris Horton time permitting) as it refers to brake scoops. This is clearly cr@p as there is only a RHS scoop - indicating it is feeding cool air the oil cooler, if there is one, or loop cooler as was the case for 2.7s.

BTW, what is up with the reference throughout the article to a "2.7 SC"? There was never a 2.7 SC just a 2.7/2.7S/3.0SC. This car is clearly a 2.7 as it does not have SC flares and runs 6x15 wheels on all four corners. If 911&Porsche World misses this fundamental stuff what else are they missing?

As for the article on Boxster brakes, reads like an Autofarm infomercial. This is a diservice to anyone who has spent a decent amount of time researching "real" brake upgrades. As for the price of £1900? Well, there is fool and his money parted every day. Of course this is nowhere near the outrageous price quoted for the "Autofarm RS" replicas from the last issue - £65k for 3.2 with refreshed suspension and brakes and lightweight RS pattern bumpers, HELLO, do the maths, Autofarm are laughing all the way to the bank. I really pity the poor soul who buys one for £65k.

Pretty sure I thought about something similar myself. Any good?

The ones I nearly got had a "shoe" to collect the air & the ducting to channel it to the discs. I was worried that the shoes would get ripped off by speed bumps / pot holes etc. & that I couldn't be arsed the keep taking them off after each track day.

I have under A-arm ducts to the centre of the hub with hub block off plates to direct the air thru the discs (rather than spilling the air thru the hubs). To duct air from the "scoop" shown in the photos in the article to the disc is convoluted and has clearance problems. I suspect it also has air flow limitations as the scoop is in an area of low pressure. Even for oil cooling the scoop is of marginal benefit and this assumes a radiator style cooler a la 3.2 rather than the loop cooler that is more likely the case for a 2.7 (which I assume the car in question actually is) which does not really benefit from increased air flow anyway. A much simpler and concealed option is to increase the size of the notch under the bumper (or add one to a pre-3.2) and seal the area between the spoiler and the cooler so all air flow goes thru the cooler rather than spilling out beneath the cooler.

FWIW, my car with no bumper notch (it has the wrong bumper) never overheats on track days.
 
In terms of oil cooling, I had a fan fitted to the oil radiator in the front wing, complete with thermostat. It cuts in when the temperature reaches the second mark from the bottom (the penultimate mark), and the temp has never gone above that. Don't track it, but do llong distance driving in hot climes.
Thought that I had better fit it, what with all the extra power/heat that the engine produces.

In terms of the brake cooling ducts, I don't really know if they work better than the norm - I have the block off plates etc. on mine. A kit from 930 (sic) I believe - the company up north, that is.
 
Yes 9MRacing sell the under A-arm kits that originate from Smart Racing in the US.

On track they certainly make a difference.
 
I have Boxster front calipers fitted to my 3.2 and i found to my cost on a Track Day at Brands Hatch i boiled the brake fluid and lost the pedal.Not enough cooling air goes to the calipers as Boxsters have designated ducts in the body.Like Richard i now have cooling ducts from the rear of the hub with the ducts attatched to the bottom arm along with the plate inside the disc. With Pagid orange pads on the front and Pagid blue on standard rear calipers along with Racing Blue fluid i have encountered no further problems and the car does regular track days and 3 trips a year to the Nurburgring and i feel the braking performance is improved over the three years i have had the modification.
So beware and it just shows that this forum is a usefull asset in gaining information and dont always believe the advertisers hype. I ordered all my kit from Pelican Parts and EBS racing and i can recommend them both
 
With regards to the original scoop mentioned in the first posting (as shown in 101 projects), I'm sure that getting one to fit the N/S would just be a simple case turning the O/S item upside down. The bumpers and duct look to be symetrical!! Worth a try!
 
Dear All,

re the oil cooler scoop for offside bumper, click on Pelican Parts link below then click on [picture] link;

Pictures speak a thousand....

Do you have these ones fitted Richard?

I am thinking of having some kind of upgrade done before the season starts and I am not too sure which way to go
 
Not exactly. I have a mixture of second hand bits I cobbled together. The weakness of the kits is that the scoop can get ripped off fairly easily on kerbs or if you go off track. I just have plain old hoses of a larger diameter than the kits zip tied in place. The effect is the same though.

You should note that you really need the hub block-off plate that Smart Racing sell so that all the air that is ducted in is not simply spilled thru the hub and instead flows thru the disc vanes for max cooling effect. 9M also has these I think.
