Ok so i have an interesting question; How much can a stock oem inter-cooler on a b5 can handle as far as boost, burst pressure , temperature's and heat soak when does it start to feel the term heat soak?.

i read something on the subject but it was on a S4 model with a stage 3 turbo, some good info some just made up stuff so i just want to lay this question out and see what any of you know as far as this little small SMIC on our cars.

any input?

 

It can handle what the ko3s can push, i think it might be ok with a ko4, but anything larger than that you need aftermarket.

 

Even with a K04 you're looking at heat-soak territory. For example, with GIAC PC-16 tuning (made for a K04) they say you must use a FMIC to keep IATs down, probably because of the more aggressive timing they use with that tune.

 

only issue would be heat soak. it can handle 25 psi. id say it depends on a lot of factors. ambient air temp, how hard the car is driven, altitude (air density). under the BEST conditions i dont see why it couldnt handle a gtrs. this means low ambient air temp (less than 50f), only a hard pull every once in a while, and a good amount of quality air. with that said, a hard driven k03 would definately benefit from upgraded intercooler under rough conditions. i understand i am evading the question, just throwing the info out there.

 

i see, do you guys think it can handle the k04 with a pc16 file just for a little while , until the FMIC can be install? i don't think it should be a problem unless under heavy acceleration correct me if am wrong.

 

youll be just dandy.

 

Under light throttle you should be fine. More than that and the IC won't be able to keep up. IATs increase, and your detonation threshold becomes more of a danger. If I were you, I'd do the supporting mods (like the FMIC) first, get everything on the car, and save the PC16 tune for last so that once its loaded, you're ready to go.

 

i see alright then, well no worry's today i when out to a shop that does the giac chip and what not and he asked for just the ecu $50 to get it flash or what ever it is they do he said if i pull it out and take it to him its alot easier for him and he can charge me a little . so tomorrow ill see how it goes, in the mean time ama install the hardware as well as that FMIC i gotta keep shaving of that bumper till it seats right.
