Re: Intercooler For 335i
hanor hanor, my science teacher say GruppeM air is virgin air. After they kena compressed by turbos they lose their virginity n become hotter so they must be intercooled.
BTW can put a bar fridge inside? Colder....

Re: Intercooler For 335i
Racing Dynamics and RPI Intercooler are the same. Looks good but performance reviews not out yet by those e90post users yet. Think it should be quite good.

Re: Intercooler For 335i
This is my lay man understanding:
For turbo engines, it is the exhaust gases that spools the turbocharger. As the exhaust gases spool the turbo, air is compressed into chambers. However, exhaust gases are very hot so the entire turbo heats up and so does the intake air that it compresses. Hot air expands and the density of molecules is lowered so not so effective combustion. To solve that, the air that is compressed needs to be forced through the intercooler to cool the air down thus also increasing the density of molecules. When this compressed and cooled high density air is ignited, combustion is better, thus more power. So the theory is that the efficiency of the intercooler in cooling the compressed air does affect the power of turbo cars.
Anyone, please correct me if I am wrong. Cheers!

Re: Intercooler For 335i
the carbon fibre material of the gruppe m are supposed to shield heat from the engine better than stock plastic cover so that intake air is not affected by the heat of the engine bay.can some one verify that carbon fibre is a better heat shield than plastic ?

Re: Intercooler For 335i
the intercooler serves like a heat exchanger taking some heat from the heated compressed air thus making it cooler so density of oxygen more for combustion.but the bigger the intercooler the more resistant to air flow and thus it reduces the boast pressure.you need to find the optimum size for the power and boast you are generating.
if you are using stock engine with a bigger intercooler you may feel a drop in low range power.

Re: Intercooler For 335i
they are used to faster conduct heat away not as a heat shield or am i wrong ?

Re: Intercooler For 335i
yes correct.
compressed air produced by the turbo is hot and need to be cooled down by an intercooler. its just this simple theory.
colder air = densier air = more air molecules = more air = power for combustion = more power.... haha
picture of turbo to show how air out of turbo is compressed.....or forced...

Re: Intercooler For 335i
oic....whaaa...good question!!!!
i agree the core is wide too leh.....its surface area is small, but thats the design to be able to fit a 335's mouth i'm sure.
i'm sure yr concern of pressure drop is negligeable bro........IMO...
