74mm small supercharger wheel for all G60 in VW Corrado, Golf and Passat to increase the boost pressure / to increase the power.
The supercharger wheel is made of high-strength aluminium 7075, CNC machined and black anodised. A suitable tuning chip, short V-ribbed belt (or thread-adjustable tensioner) should be used.
With the 74mm supercharger wheel, the increase in power is moderate. The advantage is that the wear in the G-charger remains low due to the low speed increase.
