Blower for The Demon V8
« on: June 21, 2013, 01:05:43 AM »

I got the bug to make a few parts for the Demon blower. I have a lot of prototype parts but have never built one so I decided to make the intake manifold and go up from there. I used the manual mill to rough out the basic shape of the intake and then the CNC mill to start shaping things. It took 3 tools and about an hour and a half to get to this point.








I also made a pattern and poured a few cases for the blower.




I will most likely bounce back and fourth between this and the mini bikes so both builds will take twice as long now.

Keep in mind that Steve's "twice as long" is everyone else's half as long. I'm watching this amazing work.

Got the top and bottom complete. I just need to drill the holes to mount it and port the blower to the cylinders.

Bubba's Drive Service!  I like it!

The intake is complete. The ports are drilled and the coolant passages are in. For the first time a blower is bolted to one of my demon blocks.






I'm liking it so far.

I have my blanks made up for the rotors. The length is dead on and the diameter is .125 inch larger than needed. The shaft is a pressed fit but I used a grooving tool and made some .010 deep grooves and filled them with loc-tite before i rammed the shaft thru.




Here's my setup. The fixture is steel with brass bushings. I spent better than an hour shimming and tapping and indicating to make sure i am perfectly aligned. It's ready to go. If work gets rained out tomorrow I might take a run at one rotor. The RT is for rotating and holding position. The fixture does all the work. With a .188 shaft I didn't want to rely on the RT to support the work. I was worried about the center shaft flexing. I have only allowed .005 clearance in the case so I need all the advantage I can get.
