Cylinder Heads G60. £550 + VAT (exchange)
As fitted to the Golf and Corrado. The supercharged G60 engine fits the role of supplying lots of low down power from a small engine. Benefiting from a supercharger means lots of low down punch and no turbo lag. However, if you want to release the full potential of your VW G60 engine you must address the restrictions of the standard head. Any effiiciencies found in the head will be multiplied by the supercharger.
We have measured our G60 head as if it were a normally aspirated engine. This is because supercharger boost cannot be easily simulated and has many variables such as barometric pressure, ambient temprature, intercooler effiiciency and level of boost used. We are working on a model for turbocharging and supercharging engines but for the moment we only have figures the head as if it were normally aspirated. This at least gives a fair benchmark of the improvements made.
Our G60 head shows a very healthy inlet increase of 30.9 % peak flow rate at max valve lift is seen here along with a substantially improved flow rate across the valve lift range. Exhaust improvement is 26.9% improvement at the max valve opening. These are substantial gains and will benefit the delivery of the power low down as well as peak power overall. This head will produce 156BHp without a supercharger at 6500rpm. Our estimate is 190BHP at standard 6psi boost. More is possible with higher boost although you may also wish to consider our big valve version of this head. Call us or email for more details as we may have more exact information than this as our modeling develops.
