I recently added some insulation around my stock airbox and im going to test the IAT but i dont know what the stock IAT was before the insulation. Anyone have stock IAT records? At 30-40mph 60-70mph and at a stand still?
No i dont have any pics because ive been to lazy to get the drive thing i need to hook up my digital camera card to my cpu. I actually found this camera while vacationing in mexico...Found it 15Ft deep on the bottom of the ocean believe it or not. Waterproof digital 8megapixel camera but im going to test this tomorrow and i would really love it if someone would chime in with stock IAT
Ill be going to use a genisysII today so ill have the IAT with insulation but im not taking it out so i still need the stock IAT's. As for the product i used its like double sided thick aluminum foil with bubble wrap in between. Says it reflects 96% of heat. Its used for home insulation but i figured why not try it. It seems strong enough so far to handle it and as far as looks go..hmmm..not the hottest but ill take it if its productive.
Ok so i hooked up the genisys and drove it around for a while. It is 60F here today and at stand still and hot engine the IAT was at 88F. While driving it was anywhere from 68-74degrees F. So i dont know if this is good or bad but this is with the stock airbox and insulation around it. I havent cut into the airbox to open it up at all yet. I know that ambient air temperature outside is going to play a big part on this I wish i had tested it on similar day with the insulation off to see if it really helped at all but to me 68-74 seems pretty good? Also clocked MPG according to my DIC on the way home. 10 Miles on the highway at 70MPH...23.8MPG i have the 3:43 gear ratio.
On a recent 160 mile drive I had my OTC scan tool on the whole trip and the IAT on the highway was typically about +/-10 degrees warmer than ambient as measured by the TB thermometer. Can't tell you about city or idle temps though-sorry. Hope this helps! Almost forgot--it's completely stock no mods.
