Fitted an air temp sensor in my car. Just wondering what everyone elses inlet temps are sitting at?

sickunt! id planned to do this with my setup too when its finaly put back together lol. what brand/guage type did you go? ive never seen a 'air temp' specific gauge question is, what air temp do you have?

Air temp is displayed on the hand controller screen. Yesterday was the first day i drove it wit the air temp sensor and it was a boiling hot day, but it sat in the 30's. depends how hard i get up it. keen to hear how everyone else is doin?

doesnt sount too bad considering how hot it was. just out of curiousity where abouts have you put the sensor and what kind is it?

Just checked www.bom.gov.au (http://www.bom.gov.au) and last night at 9.00 it was 29.6deg. just before the T/B. i bought the sensor through wolf ems.

saw your car at Swift again last week, whats the story?

sorry to be off topic, but how are they going with tuning it? ive heard good and bad bout them.

I had a mate set up an intake temp sensor on his 12a turbo rotary. With a crappy intercooler it got down to roughly 30 degrees while on the dyno... just cruising around it got cooler than that... which is surprisingly low.

would be interesting to see the difference with and without a front mount on LPG, to sort of see what cooling effect the LPG itself has

LPG has no cooling effect as it is already a vapour and is therefore unable to absorb any heat. How this can be explained is that the latent heat of evaporation is the energy required to overcome the molecular forces of attraction between the particles of a liquid, and bring them to the vapour state. We all know how to boil water to make steam and know that it is not too shabby when it comes to cooling things down, so I'll use that as an example. Water has a high latent heat of vaporization. To bring water to the boiling point at 100 �C, the latent specific latent heat of vaporization is 2260 kJ/kg. This means that to convert 1 kg of water at 100 �C to 1 kg of steam at 100 �C, the water must absorb 2260 kJ of heat. This is quite a high figure relative to other liquids. Conversely, when 1 kg of steam at 100 �C condenses to give 1 kg of water at 100 �C, 2260 kJ of heat will be released to the surroundings. Latent heats of vaporization vary widely. Here are some others: Ammonia: 2466 kJ/kg; Oxygen content 0% (causes pre-ignition) Water: 2259.197 kJ/kg; Oxygen content 0% (ignoring dissolved oxygen) Methanol: 1099.45 kJ/kg; Oxygen content 49.9% by weight Ethanol: 854.62 kJ/kg; Oxygen content 34.7% by weight Isopropyl Alcohol: 666.7 kJ/kg; Oxygen content 26.66% by weight Petrol: 586-628kJ/kg Toluene: 351 kJ/kg LPG doesn't qualify in the inlet tract as it is already a vapour. The above also shows why a 50/50 mix of water and methanol injection is awesome at reducing inlet temps as it gives good heat absorption and releases some oxygen into the combustion process, but not significant amounts.

Thanx for the info. fixed a massive vacuum leak last night and tore it out for a cruise. The air temp sensor hit a max of 19deg. Last night it was 15.6 deg outside according to the Bureau of Meteorology.
