I think ive read every intercooler thread in the world now and im still undecided as to which one to go for, it will be used on a stage 2+ K04 car, which will be used as a daily driver and a few track days every year.
at present ive got an s3 intercooler in the hut so obviously using this would be the best option but im not sure it will be the best for a k04 car although it was perfect for my 2+ K03 car, on the upside this has decent reduction in intake temperatures over the standard intercooler and doesnt lag behind the top brands as much as i thought it would ! the only worrys i have with this is recovery and flow rates ? im sure the pressure drop in the cooler is less than the standard cooler due to improved flow rates aswell, but again not as good as some.
The APR even though it has some impressive figures, is out for me as at £1000 is far to expensive considdering the other options.
Forge i like the idea of the easy fitting / removal, there is no doubt its the best performer when it comes to reducing the air temps in extreme conditions, with flow rates that are better than standard (for the forge the rates are better by 0.3 - but remember this is also coupled to the standard cooler so it will drop a bit )although not matching The THS (not far off it though), this also seems to recover from heat saturation the best too, the only thing im not keen on reguarding the forge is the pipe work looks all squashed like it needs resized / shaped and the fact that it will restrict the airflow to the radiator.
THS, this seems like quite good value as its slightly cheaper than the forge and means that my s3 cooler can be sold further reducing the outlay, the presure drop on this is again better than standard and the best here which helps avoid producing more heat from compression and prolongs turbo life, this is probably due to the bar and plate design and high flow endtanks like the APR, although i can help but think if bar and plate wasnt used the temperatures would be reduced further but then again you would loose the flow charactoristics so swings and roundabouts really, TBH they have managed to reduce the air temps by about 30% over standard anyway so thats quite healthy.
Anyway thats basically what ive took from reading about each intercooler brandand i was wondering if anyone had anything to add to help make up my mind or if i had picked up any wrong info
