Air intake thermometer

[rt172]

Craggy mentioned something to me about these £10 digital thermometers from Halfords, and that people had managed to set them up as air intake temperature gauges by running the cable through to the engine bay.

The effect of air temp. on performance is of interest to me, so Im going to have a go at doing this (cheap if I feck it up!) but.....what is the best route to go to get the sensor cable from engine bay to interior? I wouldnt know where to start.

if you get all this done, then lets see some pics, it interests me too...

oh an its probably through the grommet under the expansion tank mate

 

[rt172]

Thanks Brun - will take a look. Hope I dont have to remove any of the dash to get at it.

Will put picks up if I manage it.

 

[BRUN]

you shouldnt have to mate, move the seats back and pull the carpet back a bit from the passenger side footwell

 

[adiclio16v]

yeh thats a good idea i might hav a crack at that too

yeh theres a big grommet under the header tank that ive used for my stereo cables go through that

Cool...might even manage to do it tonight. Might fork out for an AP22 next month

Could really do with an engine bay temp. sensor as well as one for the air intake. Hmm....

did the same for gengars install when we put his amps under the false floor, were worried about the temp through ventilation. worked very good, and was v cool when we switched the coolign fans on and saw the temp drop!

got fan from maplins

 

[Craggy]

there 15 quid from halfords, and theres a long lead comes with it with tiny thermometer gadget on end. perfect for measuring the air temp , put iy just before butterly on valver i would imagine best place in the airbox you can always move it.

 

[Colin_S]

It would be cool to move the temp seson in the Valvers from the Mirror to the air intake then have that commin up on the dash.

 

[Craggy]

yeah that woud be a sound mod

 

[BRUN]

what do these temp sensors in halfords look like then ?.....cos im goin there in a min

 

[Craggy]

just a little square with l.e.d screen with temp on it. a couple or three inches square an a cm or 2 deep. obviuosly has wire coming out it too

yeah ive had a set up like this for the past 2yrs in my valver. i fed the lead thru the bulkhead and into the airbox/sealed air filter, and screwed it directly beneath the heater controls on the 19. works a treat. with induction kit, underbonnet temps can reach 50degrees on a cruise, wile sat in traffic, the temp goes off the scale. with a sealed air pipe from the frotn bumper, to the standard air box, the temp never goes above 15degrees c even during hot summer days wile driving. i have had -2 on the air temp in airbox during winter. the car shifts so much then!

i too done this a long while ago ,dont go to halfords for the gizmo. go to maplin electronics they are ten pounds and are excellent.

 

[BRUN]

bondy do u know the part number of the one u used from Maplin, as i cant seem to find anythin

 

[rt172]

Bondy - cheers for the tip. Wasnt keen on the Halfords ones so I passed. Theres a Maplins 2 mins walk from me so Ill go and ask what they have.

Why not get a cordless one. http://www.oregonscientific.co.uk/product.asp?c=2&s=11&p=141http://www.oregonscientific.co.uk/product.asp?c=2&s=11&p=141

Also try this link. £20 and can pick up signals from three sensors (but just 1 included!)

thats very handy!

it would be very good indicator on rollin rds to test inlet air temp and ref it to output, and check for any diffs.....cool.

also allow us to compare the diff between diff IKs!

 

[bondy]

here you go ben its called a small temp module,order number 011940/1. part number i think is yu07 . hope that helps

 

[Rajk]

bondy did you show me this at the rolling road, with the pipercross airfilter

 

[bondy]

think so mate showed a few people.

 

[Padso]

Surely a cool place for this mod would be to wire it to the radio screen on the new clios in place of the temp reading from the wing mirrors.



Has anyone tried this yet it cant be too complicated can it?

 

[Tom]

tried it today f**ked it up big time but then i just guessed

 

[Paul16V]

My muthas got one of these in her car. Got it from halfords I think. Its an outside temperature thing. Always seems a high temp though compared to the standard renault one. Dunno about accuracy
