In Europe the 2.0 i4 had Cvvt from around 2003 already
Thats right, I got my cvvt in february 2003 and the motor/cylinder head has 2002 markings stamped all over it.
"The CVVT unit is positioned on the exhaust camshaft and controls the intake valve timing by advancing and retarding the intake cam in relation to the exhaust cam. The CVVT system increases volumetric and thermodynamic efficiency, which helps the engine deliver improved performance at high rpm and increased torque at low rpm. With better cylinder charging, fuel economy is also increased. By optimizing valve overlap, NOx emissions are reduced due to the resulting Exhaust Gas Recirculation (EGR) effect." - From HyundaiMotor.com
I´m curious if it´s possible to manipulate the cvvt system for more performance gains on NA basis?
Did this guy Airborne ever get to work on the cvvt performance aspect? He said that in Korea they had made some good hp gains with it.
