If you can help I need these measurements, thinking of producing supercharger kits for A-SERIES. Using amr500 supercharger and manifold adaptor.

Will need for both short and long water pumps

I got a spare A15 just put back together i can give you those measurements

That dimension is the same A12/A14/A15.

The bolt bosses on the side of the engine differ A14/A15 and A12. Also older A12 vs newer A12.

My new supercharger crank vpulley with 6rib flat should be available in a couple of weeks. In the mean time i have picked up a 120y to use for making parts for a-series engines.

What water pumps are more common short or long? or should i make parts/pulleys for both?

What water pump is this suited for A15 i need to replace mine as the new pulley is to small to go over the waterpump i have got at the moment.. so do i get long nose short nose?
also my alternator doesnt suit also the shaft is to short
so who ever has put one of these kits on their A15 could you please tell me what parts are on your motor thanks

There been a big demand for more gilmer sets, so I will design a water pump pulley that fits both long and short pumps.

Can anybody send me a short water pump pulley so I can get dimensions from it?, I will return to sender at my cost

Apart from the offset differences between the long and short nose water pumps the PCD of the 4 bolts that mount the pulley to the pump is different. On the short nose pump the PCD is larger. While I think of it the centre hub that the pulley locates on is also larger on the short nose pump.

yes, there will be a separate hub

I have produced a few more gilmer pulley sets suit long water pump. Available next week
