Intercooler Questions
-
hello frens, currently im doing a small research abt intercoolers, wat does it do and how does it help on a turbocharged cars and lorries (eg: 5 tonners). I just need a some details will do...help me out can?
just...wat does intercooler do and help for a turbocharged cars and lorries?? any difference??
thanks!

Intercoolers
When air is compressed, it heats up; and when air heats up, it expands. So some of the pressure increase from a turbocharger is the result of heating the air before it goes into the engine. In order to increase the power of the engine, the goal is to get more air molecules into the cylinder, not necessarily more air pressure.
An intercooler or charge air cooler is an additional component that looks something like a radiator, except air passes through the inside as well as the outside of the intercooler. The intake air passes through sealed passageways inside the cooler, while cooler air from outside is blown across fins by the engine cooling fan.
The intercooler further increases the power of the engine by cooling the pressurized air coming out of the compressor before it goes into the engine. This means that if the turbocharger is operating at a boost of 7 psi, the intercooled system will put in 7 psi of cooler air, which is denser and contains more air molecules than warmer air. -

Intercooler
The 3.3-litre version 911 Turbo superseded the Turbo 3.0 in 1978. It introduced an intercooler at between the compressor and the engine. It reduced the air temperature for 50-60°C, thus not only improved the volumetric efficiency (in other words, the intake air became of higher density) but also allowed the compression ratio to be raised without worrying over heat to cylinder head. Of course, higher compression led to improved low-speed output. -
err... u driving a turbo charged car or lorry? hee hee just asking lah...

I driving 5 tonner!! and my normal daily usage is a NA- corolla 1.3 hehe..Originally posted by ndsef:err... u driving a turbo charged car or lorry? hee hee just asking lah... -

hes driving a lorry with a BIG ASS turbo in it thats all i can say.....900NM of torque...crap thats alotOriginally posted by ndsef:err... u driving a turbo charged car or lorry? hee hee just asking lah... -
oh yea 4got to add...the bigger the intercooler the better the cooling efficiency and hence more power but then again the engine loses abit of response time...which is y u dun see cars with small turbos fitting in big intercoolers and i dun think 5tonner is intercooled as i explored its internals during my WPT....maybe i'm wrong la

My WPT is paper WPT one ma...(oops) but i can confirm 7-ton dun haf...and yes...plz drive properly....the 3,6 and 9K click bonus is the easiest to obtain compared to IPPT and marksman $$$Originally posted by KhidMasAE86:got lah!! where u see dont have...have leh..u better check again...WPT u see wrongly...
