Supercharger Jack Shaft continued

Still working on the front jackshaft bracket. The bracket that attaches to the head has been machined and a paper template is printed out for test fitting. The bracket will still have nose piece to support the outer bearing.

Test fitting the bearing part of the upper jackshaft bracket.It still needs to have the bolts holes machined for attaching it to the lower bracket. The round pocket is for a bearing.

A small bracket will be added between the supercharger and front jackshaft bracket to add some forward and back rigidity.

Supercharger Jack Shaft

The pulleys finally arrived and the supercharger housing for the jackshaft has be started. It is made from a 1” thick piece of aluminum, with a pocket for the sealed bearing. The housing clamps onto the nose that I machined into the neck of the supercharger. I ended up making a new supercharger shaft to fit the 20mm opening of the 8mm 32 tooth cog pulleys.Sup-Jack-pulley

I am working on the serpentine belt design. A separate belt will be used for the water pump-alternator and the supercharger this will allow the engine to still run if I have a supercharger failure.

Starting to design the brackets for the serpentine end of the jackshaft. I print out the design on paper to make sure it fits before machining piece out of aluminum. The bracket will be designed to allow the installation […]

Supercharger Nose Modifications

 

 

Started working on shorting the nose of the Gen V supercharger .

 

I turned down a new shaft  that is about 4” shorter then the originalnew-supercharger-shaft

Pressed on the bearing. The knurling on the shaft holds the drive flange

Flipping the new Gen V Supercharger

Started work on turning the supercharger 180 degrees today. The idea for turning the supercharger around is so that the throttle body is facing the front of the car and allowing for a more practical placement of the air cleaner. It will also allow the heater hose and thermostat to be on the front of the engine.

The lower intake manifold is also flipped so I will need to make a couple modifications to make it fit. I first needed to modify the lower intake manifold so that it would clear the water pump. The area was milled open was filled with 1/4” aluminum plate.

This is the rear of the motor showing the gears for the Gen V supercharger. The motor originally came with a gen 3 supercharger but in order to turn the supercharger around I would need to change the direction of the rotors. Unlike the Gen 3 the Gen V supercharger bolt pattern is symmetrical and I was able to flip the rotors over and thus moving the drive pins over from the right to the left hand side. I will be making a jack shaft to connect to the front of the engine.
