issue with my cooling mod
Discussion
Having read all I could find on the tunnel cooling mod, I decided it was time to get down to it. And instantly ran into an 'every one's different' situation. Two of my cooling ducts have already been diverted to cool the front brakes. I am therefore only going to divert one of the remaining two to the tunnel. The question I would welcome input on is this: the heating box has two inlets closed off already, I presumably have to close off the third to get some pressurisation from the remaining one input duct when moving. Will this cause problems when I use the fan? Basically will it get choked by having so many of its input apertures closed off?
just a thought, and I'm no expert, so don't mean to interfere. The white laced ducting has a sharp right angle upwards almost immediate after entry point, would this tube not be better following the path of the other 2 pipes making a gentler path? Maybe the clam wont allow this option.. but surely the smoother the entry the more effective. Should there be any bottleneck of airflow, this would be better contained further down tube than buffering up near the front.

My car is used almost exclusively for trackdays. Never had an issue with heat/brakes in 7 yrs.
Not sure if the ducting is necessary or not, but I had the long pedal at Rockingham (not too funny at 110 at the end of that long straight lol!) and I was concerned that the infill panels, which I made and fitted later, could restrict air to the brakes if they do their job so I fitted the ducting at the same time.My car is used almost exclusively for trackdays.

(I had fresh high temp brake fluid and appropriate new updated pads at Rockingham by the way, hence thinking I must need some cooling

Good point. Don't know what effect those front infills have on brakes, as I don't have any (infills that is). To me they are another pointless mod - who has issues with turn-in in a Noble? So in real world terms why would you look for more front end grip? The only thing you will notice on road and track is that your front tyres wear out quicker (and quite possibly as you suggest they may help fry your brakes). If you're planning on doing Vmax events in a high powered car then possibly there might be some noticeable stability at high speeds provided by the infills.(I had fresh high temp brake fluid and appropriate new updated pads at Rockingham by the way, hence thinking I must need some cooling

I've no idea either, but it is interesting that the GT-R designers spent ages getting air to go into the front engine and wheel area, rather than trying to stop it....Page 4 under the "birth of a ledgend" section here

They were more interested in getting air to flow around the side so that they could suck out the air shoved in at the front it seems, hence the subtle canards added to the MY11 front bumper.

)I too have never had any brake problems but it does depend massively on the way you use them , brake rotor condition ect .

The infill panaels main advantage is to reduce front end lift at speed , not sure why you feel it will increase tyre wear , if anything the lack of lift and slight improvement in front end grip should improve tyre wear as you get less slip on the front tyres .

More downforce pushing tyre into tarmac = more wear.I too have never had any brake problems but it does depend massively on the way you use them , brake rotor condition ect .
