Minor Update:A/ Chris sent down a used timing belt to mock up the cam and water pump drive. The original idler is a "spring loaded" tension device. It is going to be replaced with a fixed, manually adjustable assembly. The new bearing will be a double row angular contact bearing assembly, rated for 10,000 rpm. The 8 mm mounting bolt is going to be replaced with a 10 mm ARP stud/nut/washer arrangement. Rest of the design, on the fly, based on the mock-up.
2/ I began fitting the stainless steel exhaust flange fabbed in Britania . . . . . . it didn't fit . . . . . . the bolts wouldn't even go through the mounting holes . . . . . (sigh) While enlarging the holes, it was noticed that some holes are: "out of position" . . . . . . Go figure . . . . . Bring on the rat tail . . . . . .
d/ Steve Fox of Power Train Technology has kindly loaned me the smallest motor diameter, 10 tooth, 20 degree pressure angle pinion, high torque Hitachi starter in his inventory. That's the next offer up.
BTW, for those of you needing starters, clutches, flywheels, bellhousings and the like, Steve's company is cutting edge. Steve is also the original designer at QuarterMaster Industries, responsible for many of the original cutting edge QM designs. Steve is now out on his own, providing the same cutting edge quality. If you use his stuff or inquire about his services, let him know you heard about him from yours truly.
So, the flog for Speed Week 2018, continues . . . . . . . . . . .

Later dudes,
