I am using a Danny Bee drive belt with remote electric water pump, and want to maximise the water flow into the engine.
The water pipes from the pump attach to the drive belt cover as shown in picture below. The previous owner had 3/4 NPT threaded fasteners in the water inlet holes, but I don't like that idea, and want to use proper mounting adaptors, at the maximum size I can find. The hole into the block is more like 22mm (I couldn't measure it properly)
3/4 NPT internal diameter is about 3/4"? (I'm not used to NPT) which is about 19mm. The biggest proper adaptor I can find is from Meziere (shown below), but that is only #12 which is therefore about 17mm.
Does anyone know of any adaptors for the SBF which will allow me to fit something bigger without the restriction? It seems a bit daft having 1.5" pipe from the radiator to then try and force it in 2 x 3/4" (or even smaller) holes.
Area of 1.5" diameter is 1.77sq.in. Area of 2 x 3/4" holes is 0.88 sq.in. Area of 2 22mm holes is 1.18 sq.in. Area of 2 x 1" holes is 1.57 sq.in.
