Hi

i decided to see what the air inlet temps were like on my car with my cai setup fitted - looks as if i need heat wrap or heatshilding i am surprised at the results !!

It was a 30 degree day today, Here are the air inlet temps recorded on my normal drive home from work

Idling at lights - 60 deg

Extended idling / Low speed crawliing for 10 minutes total , is 85 deg

Freeway cruising and country road driving 32 deg

That U beaut stainless pipe maybe good for Flow but it must be a Biatch for heatsoak.

where were you measuring the temps at? thats not so surprising considering the large amount of piping needed to get air into an EL motor, there is a lot of opportunity for heat soak.

if would be interesting to find out what the stock temps are under the same conditions....

how and with what were you measuring the temps?

idling and low speed crawling temps are too flash, possibly some power down low to be gained from standstill, depends on many other factors though. But i would think some heat sheilding could make it run a bit smoother in some conditions.

[edited]i actuallly have some insulation u may be interested in. ill post a pic if u want. i used it on my XH snorkel, and my LASER fuel lines and "custom" CAI.......

30 degree day today! And that is hot.

Sorry had to say it. I would get a stock set up and do the temp check as well. Mind you most CAI kits are only there to free up air passing thru and not going to cool down the temps themselves. With the freer flowing air you may see a slight decrease in temps, but dont expect much.

just taped a digital themometer to the filter and registered the readings on the inside, i actually did this test when i had a stock setup in my el ghia and the readings on a similar day were about 5- 10 deg above ambient constantly

Thinking about heat wrapping my extractors or getting new HPC PH4480's, I work for an Exh Wholesaler so either is an cheap option

ive noticed a similar problem since i put the 3" pipe. the car likes to ran hotter

Where are you drawing your "cold air" from? Inside the engine bay or from an external source???

redGhia · 01-28-2005, 23:47

"cold air is drawn from engine bay directly behind the headlights with the original air ducting for the factory box remaining and delivering air straight onto the pod filter

I removed the blanking plates off the bonnet vents and noticed warm air coming out whilst idling at the lights now, Since removing them it has gone from the s/steel air pipe being to hot to hold onto comftably to nearly stone cold after driving for extended periods

Will monitor temps closely but have allready noticed about a 30 degree reduction

Ahhhh so you have a HAI. Think about it you are sucking hot air from the engine bay. Think about it the exhaust is producing heat and the radiator is giving off heat into the engine bay. Know wonder you are seeing such high air temps. A CAI needs to get air from outside the engine bay some how. Usual way is to cut a hole and mount a pod in the wheel arch.
