jevansio Posted October 8, 2009 Share Posted October 8, 2009 (edited) I've got UK discs on my J-Spec and therefore have cut away that metal shield thing on the hub. Is there any point in fitting something along the lines of these ducts with some tube to somewhere like the front bumper ducts or could I just as easily mess up whatever brake cooling Toyota has? http://www.demon-tweeks.co.uk/products/ProductDetail.asp?cls=MSPORT&pcode=MSD42114 A similar stock setup on a Lambo & 911 http://www.lamboweb.com/Repairs_Section/Diablo_Repairs_Brake_Air_Ducts.htm http://p-car.com/diy/coolingduct/ Edited October 8, 2009 by jevansio (see edit history) Link to comment Share on other sites More sharing options...
Kirk Posted October 8, 2009 Share Posted October 8, 2009 id personaly say that the method above would be alot more practical than stock. Definatly a good upgrade! The dust shields you have cut off dont do much in the ways of actualy ducting air at the discs themselves, and with them cut there more or less useless.

jevansio Posted October 8, 2009 Author Share Posted October 8, 2009 Also found this kit for an Evo http://images.google.co.uk/imgres?imgurl=http://i85.photobucket.com/albums/k61/smikeevo/DuctTestFit.jpg&imgrefurl=http://forums.evolutionm.net/motor-sports/277934-hot-lap-motorsports-brake-duct-kit-installation.html&usg=__aY9mjA4zy3z8Yg2fhvL8zETd5X0=&h=1024&w=768&sz=335&hl=en&start=2&um=1&tbnid=A6mXsscNnFrOTM:&tbnh=150&tbnw=113&prev=/images%3Fq%3DForge%2BEVO%2BBrake%2BCooling%2BDuct%2BKit%26hl%3Den%26sa%3DN%26um%3D1 Yeah, I guess all the old ones do is protect the disc from crap. How beneficial is this sort of upgrade? Link to comment Share on other sites More sharing options...
Kirk Posted October 8, 2009 Share Posted October 8, 2009 definatly a huge improvement over stock! You will have air ducted directly at the disc thus being very efficient way of cooling! pretty sure paul whiffin runs a similiar sort of setup on his car!

Kirk Posted October 8, 2009 Share Posted October 8, 2009 I like the idea of those very simple and effective, not as much as direct ducting to the disc itself like but non the less If you get some get me some Link to comment Share on other sites More sharing options...

Makes the Lambo ducting look a bit tacky. Link to comment Share on other sites More sharing options...
jevansio Posted October 8, 2009 Author Share Posted October 8, 2009 They're $299!!! More pics from an M3 forum http://home.comcast.net/~biodan/cooling.html I take it the point of the ducting is to direct air at the centre of the disc so it vents out of the vanes at the edge of the disc, not to directly point the air at the disc surface where the pad grips Link to comment Share on other sites More sharing options...
Kirk Posted October 8, 2009 Share Posted October 8, 2009 OUCH something similar could easily be mocked up for half the price im sure Id say your theory on ducting is right. Seems to be far more effective than just directing air at the disc Link to comment Share on other sites More sharing options...
Wez Posted October 8, 2009 Share Posted October 8, 2009 I am assuming the air leaves from the centre outwards through the vanes, if so then directing some more air into the centre should be good, however if the vanes pull air in and push it out through the back then forcing air into its path isnt going to work. Surely the latter function would be silly as that would potentially throw hot air onto the bearing which cant be good. Anyone know for sure?

jevansio Posted October 8, 2009 Author Share Posted October 8, 2009 Pretty sure I've just seen a pic showing the direction of air as entering at the centre & exiting out the disc edges on here (was a post by CW on direction of disc installation) Lots of cars seem to have OEM brake ducting, & lots of aftermarket kits for sale for other makes, I'm guessing this could be a good upgrade to the braking of a stock UK spec setup Link to comment Share on other sites More sharing options...
SupraAyf Posted October 8, 2009 Share Posted October 8, 2009 I thought you were going to say $20 Jay, but $299:blink: Link to comment Share on other sites More sharing options...
Scott Posted October 8, 2009 Share Posted October 8, 2009 Definitely from the center out for the air. I like the look of the attached pics. Surely it would be better to have the intake scoop working from underneath the car though? I reckon you could make something up that would be much better. Have it going the entire width of the arch liner and hanging down an inch. Then have it looping as it is in the pics to avoid the wheel/tyre. FWIW my wheels would definitely foul on those. They would need to be bespoke. Link to comment Share on other sites More sharing options...
jevansio Posted October 8, 2009 Author Share Posted October 8, 2009 (edited) I was thinking of using the vents in either my front bumper (red), or I think the vents in my RMM lip are intended to be brake duct vents according to things I've seen on the Corvette forum (blue) Edited October 8, 2009 by jevansio (see edit history) Link to comment Share on other sites More sharing options...

jevansio Posted October 8, 2009 Author Share Posted October 8, 2009 I'm thinking something like the BMW setup for the bit on the disc http://home.comcast.net/~biodan/pix/tubeJoint1.jpg Link to comment Share on other sites More sharing options...
AndyT Posted October 8, 2009 Share Posted October 8, 2009 Looks that way mate. The spinning disc would be getting a nice uninterrupted stream of cool air instead of the normal turbulent flow. Of course, you have to work out if the unit will direct the flow to the same place on your car. I don't think there'll be much in it. 299 bucks is a fair 'ol wedge though.

bignum Posted October 8, 2009 Share Posted October 8, 2009 I`ll try and get some pics up of mine, made from large softner bottles fitted under the car piped to the back of the disc, ive had them fitted for about 5 years now. Link to comment Share on other sites More sharing options...
bodilx6 Posted October 9, 2009 Share Posted October 9, 2009 Uuh, please do. That would be nice to see as we know you USE the car. Did you notice any consistent difference or *could* it be placebo as so many "clever" DIY solutions often is? Link to comment Share on other sites More sharing options...
