Great work, nice to see someone who is not frightened to get the tools out and save some cash. I made a cold air box for my last rally car, it was very similar alloy sheet bent into a box and rivited together. I used heat reflective hose which ran too it, where a cone filter was used, it was fitted directly behind the front grill and I sealed the joints with speed tape. When following a similar car on a rally at Longcross we were catching him on the straights which I am sure was down to the RAM AIR of the cold box. We were all using standard 1000cc cars and they had the advantage of about 5 stones less in the weight of the crew!

I went 1 cheaper!
Just bolt a universal K&N directly to the throttle body.
Cost about £40 all in.
Details on NAM (somewhere?).

ScottyBoy,

What ITG filter did you buy for this?

My Alta has started to eat itself (rubber has split around the actual filter) and so I need something to replace it with - but don't want to get rid of the heatshield.

Any help would be much appreciated.

Cheers

Joe

Yeah but won't that suck in an aweful lot of warm air just sitting down there right nexxt to the block, charger, IC etc? You have to be wary of that a little bit on the S... not so much on the ONE and Cooper but for sure on the S

We did some under bonnet temp tests recording the temps just before the throttle body.

It made very little differance with or without any heat shields, as soon as the car moves at around 15mph all the results were within 1 degree, at 30 mph they were all the same temps.

Joe i actually havent found on to be the right size. There was 2 ITG ones and one was to small and one was way to big so im still looking.

Looks sweet!

Any chance you could share the template / dimensions, please?
Not really as i didnt use any measurements my work was pretty much taking the alta box out and stencilling around it lol its worked a treat tho and saved me a fortune.

Ohh a camsahft has been living insidemy cylinder head for the past 4 month.

Last RR result was 210 BHP with an M7 CAI.

New result with standard airbox and Newman Cam was 240 :) happy times

Its a good job I did my tests on a MINI, all cars have different under bonnet airflow, the MINI is good for clearing out the hot air when moving on the road.

I did not measure BHP just the air intake temp before the throttle body.
