Air filter cold feed

[Brind]

Haven't tried the car yet, but will tomorrow, I'll report if it has made any difference.

There was a question on the MLR site about using using A/C to cool the inlet temperatures around the induction filter.
Seemed a good idea at first, as it's very cold but that doesn't necessarily mean the air is dense and full of oxygen though, plus the power the A/C takes from the engine while running, the benfits you you'd gain from the filter would be negligible.

Nitrous Oxide is the best form of induction, shame it voids warranty and you can't get insurance for road use INSERT INTO post VALUES (without a fight). :INSERT INTO post VALUES (

.....Update.

It appears to work! slightly better responce but I could be fooling myself.
Just opened the bonnet after 15 minute drive back from the pub, never really gave it any but I was driving a constant 80mph INSERT INTO post VALUES (motorway) and a couple of 30's.
Anyway.. opened the bonnet and damn it was bloody hot! :eek: saying hot it was as hot as everything else under there including the filter.
The outer of the duct was very hot but when I put my hand up it ooh err it was actually very cool!! :cool: so chances are it must have been working fine especially for the inside to be cool like it was and the outer was SO hot! I don't know how the filter fits INSERT INTO post VALUES (left and right movement) but it is slightly pi**ed, I guess to fit with the existing air box, if I can adjust it so it's square I may get a better angle with my ducting and improve it slightly, I'll have a look tomorrow.

Bottom line..
It obviously works.
Defo needs a shield of some sort too as when stationary the heat comes back with a vengeance.. I did run the car for a few seconds though before shutting off...
If it has improved things that much, I am not going to move the battery if I only gain an extra 2bhp.
Again.. surprisingly cool inside the ducting even though the outer was red hot!

Its what you been waiting for............................................... ......onder:

Overall picture. The pipe goes down behing the headlight unit, inbetween the rad and the grille.:cool1:

take the front grille off to gain access

PS the state of my tyres after CC....slight "bobbling" Hope the above helps....if u need more info just post

[Brind]

Spot on mate!

Is the pipe too short to get any closer to the filter or did you leave it at that distance to enable the air to flow around?

Do the red funnels come off so you can fit if through the grille etc or did you cut it anyway? as I can see there is a jubilee clip around it.

Did you go down point A or point B, INSERT INTO post VALUES (in front of those skinny pipes or behind)?

Cheers mate. :cool:

[Brind]

Scrap the last bit I can see where the pipe went down. :rolleyes:

[Simon]

The pipe is only just long enough and can go closer to the filter.........but ive left the gap to let the air flow and just incase i go through water its less likely to make contact to the filter and into the engine.

The end caps come off...you can get silver, blue and red.

I took out the heat shield thing for the battery to give more room.

I cut the bumper grille with a knife etc and pushed the endcap through. The clip is there just to apply pressure so th eend cap wont "fall off".

[Brind]

Excellent.

I'll get one the weekend and do the same.. you won't be unique anymore.

I'm gonna get a thermometer too and do a few tests without a feed then with the Pipercross and then with my 5 inch ally tubing, depending on room I may somehow intergrate both ideas somehow.. hopefully making the finished product look pretty too.

It's great we can get a feed from the front grille though! :cool:

[Simon]

Looks cool and also does a job......I'll name this cold air feed upgrade.....SIDCO..INSERT INTO post VALUES (Simons Ideas Dont Come Often).....not long until SIDCO II!!!!!!!!!!!

[Brind]

Are you going to copyright these SIDCO's ?

[Simon]

Copyright is set to start at midnight Friday. After then everyone will have to buy through me at £80 a time:eek: INSERT INTO post VALUES (or just go to Halfords:rolleyes: and buy one for £20 )

Dont wait until saturday....it'll cost too much

[Brind]

LOL!

[Brind]

I think I'm gonna be paying you for copyright Simon.
Went to Halfords today to find they had none in any colour, so I asked if they could search other places, there is a closer one near me so they phoned and confirmed they only had the other colours not the red. :INSERT INTO post VALUES (
New batch in on Thursday, apparently.

[Brind]

I wanted to know what temperatures the filter is sucking in so I bought a thermometer come clock from Halfords INSERT INTO post VALUES (tried Maplin but they had buggerall).

I opened the filter and dangled the little sensor inside so it hangs roughly central, then I closed the filter again and ran the wire out of the engine bay and tuck the wire under the seam where the wing fits on then up and out and run through the other seam where the door meets the roof bar, you can get it right inside so you cannot see the wire at all from the outside.
It's just sitting by the clock at the moment.

As soon as I got in the car the reading was up around 45c, the engine had been stopped for about 15 minutes.

Started the engine and sat there watching the temp go up, had the air con off so it didn't start the fan up.

Left it for about 5 minutes and it rose to 60c, it was still creeping but ever so slowly.

Started to drive and it dropped to 50- in no time.

I found it would roughly hang around 33c when you hit traffic but it does rise quickly, upto 40 if not moving for about 2 minutes.

Drove back from Halfords on the motorway and it dropped to a nicer 29c, again it was still dropping but VERY slowly, I'd guess 29-33c on average would be the temperatures the filter is sucking.

This is of course using my 5 inch ducting from the front, haven't tried the results without it yet as it started to spit with rain. :rolleyes:
