[QUOTE="SilverBullet, post: 713840, member: 11244"] Yes bro I know exactly theoretically what an intercooler does..but just sharing practical info from my real life experience..at that time onwards there were no other changes to the car that could have contributed to the lower oil temp..anyways upgrading the oil cooler would be the best option.. My understanding is, intercooled air going into the engine also reduces the resulting the exhaust gas temp..the exhaust gases passing through the turbine section of the turbocharger are extremely hot under extreme driving conditions..this heat passes through the turbocharger unit and contributes to the heating of the air being compressed in the compressor section of the turbo..if left uncooled, this hot air enters the engine, further increasing internal temperatures..this leads to a build-up of heat that will eventually stabilise, but this may be at temperatures in excess of the engine's design limits - 'hot spots' at the piston crown or exhaust valve can cause warping or cracking of these components..high air charge temperatures will also increase the possibility of pre-ignition or detonation..detonation causes damaging pressure spikes in the engine's cylinders, which can quickly damage an engine..these effects are especially found in modified or tuned engines running at very high specific power outputs..an efficient intercooler removes heat from the air in the induction system, preventing the cyclic heat build-up via the turbocharger, allowing higher power outputs to be achieved without damage..also our turbochargers are oil-cooled, hence excessive heat from exhaust gas may be exchanged to the oil while cooling the turbochargers and then going back into the engine causing higher engine temps..anyways just a thought :) [/QUOTE]
