Black aluminium CSP crankshaft pulley, small diameter for Type 1 engine

Details about : Black aluminium CSP crankshaft pulley, small diameter for Type 1 engine

High resistance, solid CSP crankshaft pulley made from black anodised aluminium
Small diameter model compared with the original: 146 mm
Weight: 390 g
Laser engraved graduation scale for precise setting of the timing.
Perfectly machined lubrication grooves for same tightening as the original.
Warning: the use of a "small diameter" crankshaft pulley is not without risk and is therefore only for experienced people.
A pulley with a smaller diameter than the original one will result in reducing the number of dynamo or alternator rotations. This allows higher revs to be reached more quickly without the belt coming out of its groove. But be careful, this reduces the turbine speed and therefore engine cooling.
Therefore, it is reserved for major tuning operations or in the case a Porsche turbine is used or if you just want to slow down cooling.

For tuned Type 1, Type 2, Type 3 engines
We recommend you use the following shorter alternator belt: VC60028
