Double Crank Pulley

Hello all!

I talked to a friend of mine about trying to modernize the pulley and belt system of the 1.9L. He had a few ideas and I had a few ideas so would like to run it by all of you for other opinions. Bear in mind that I have full machine shop access including CNC and other equipment so fabrication of a custom part is not a problem.

There are two scenarios we are exploring:

1) We make a serpentine belt/pulley system which can be easily expanded to include A/C or any other belt driven peripheral. This system would include either a single or double belt tensioner and fixed mounts for the alternator.

2) We create an aluminum double crank, water pump and alternator pulleys to replace the existing units. A thin double belt drive system has crossed our minds since we use these on hot rods all of the time.

This scenario came from having to put the A/C system on Stealth and no pulley to drive it. And since there is no harmonic balancer on the engine, the couple of hundred pulleys we have in stock are somewhat useless.

Let us know what you think.
