I have a gps looking scantool that I have setup to show inlet temps.remember its not just the intercooler that heatsoaks. piping, crossover and inlet manifold all soak up heat.

I dout the crossover will heat the air significantly due to speed and pressure of the boosted air going through it-no time to transfer significant heat to air (and no fins). If the intercooler was still too hot to absorb and dissipate extra heat created from compression of air by the turbo @10psi, this makes sense-heat would have nowhere to go. My mechanic says its possible but hes not sure. If it is a heat related issue, ill hopefully find out tomorrow, but that what it feels like to me Link to comment Share on other sites More sharing options...

Never had any say Panda I <3 Floods Silver Donating Members 11,198 Member For: 13y 5m 17d Gender: Male Location: South West QLD Posted 20/09/11 08:40 PM Share Posted 20/09/11 08:40 PM It's also worth noting that the air coming through the crossover isn't pressurised.. Yes it'd be rather high velocity but it's gotta pass through the turbo before the pressure is greatly altered from atmosphere.My last car being a WRX suffered from heat exchange when idling after being run hard with the intecooler mounted directly above the engine.. I think the problems gotta be more then simple heat exchange.. Especially with 18*C temps outside and car going from absolute cold then just idling for 10 mins..

The intercooler is hot to touch 10 mins idling, super hot to touch after about 13 mins idling...cant help the airtemps. Problem was duplicated. By the time I drove about 1km, gave it 3 good hits, and on the third hit power was back to normal turned left into my driveway touched the intercooler and it almost burnt me lol...wowI think its a comination of heat everywhere and the ecu cutting timing/power Edited 21/09/11 04:00 AM by Garrettba03 Link to comment Share on other sites More sharing options...
FAST-XR EVIL T Member 259 Member For: 16y 1m 9d Gender: Male Location: Liverpool NSW Posted 27/09/11 04:05 AM Share Posted 27/09/11 04:05 AM are you saying that the cold side of the cooler is too hot to touch while idling? that doesnt sound right...even at idle, once your engine is up to temp, the thermos will cut in and draw in that 18 deg air through the cooler, it should not get hot at all....even the uncompressed air passing through the cooler at idle will not be that hot, it only gets warmed up as it passes through the turbo housing which will only add a few degrees to it... so even the hot side of the cooler should only be slightly warm at idle.... cold side should be stone cold still if ambient is only 18 degrees Link to comment Share on other sites More sharing options...

Feels slower than stock and revs harder then returns to normal after a minute so I know it's just cooler heat soak. Link to comment Share on other sites More sharing options...
Barra Donating Members 467 Member For: 16y 2m 3d Gender: Male Location: Toowoomba Posted 27/09/11 09:22 PM Share Posted 27/09/11 09:22 PM read the intake air temps from computer to see how much heat these things pick up sitting in traffic. one moving it drops pretty quick.I get heat soak with an aftermarket cooler too. Getting readings from OBD2 port and it climbs from 3 deg above ambient to up to 20 deg over. It's does cool slightly with radiator fans and more so when up to 80kms/h and over.
