Just a quick note to let people know I haven't fallen off the face of the earth...
Many non-racing interruptions, but slow/steady progress. Oil system is complete other than in-car plumbing to tank/filter. Engine coolant cavity is finally water-tight; should
not have taken long, but every little detail wanted to fight me. So the engine is complete other than buying/plumbing/flowtesting a fuel system (Hilborn 4-port, 150B pump) and bolting up the magneto that's almost finished being built. Discussed dyno time with a local shop that specializes in staged-turbo diesel engines for pulling competition- the dyno can measure up to 4,300 ft.lb. of torque! I certainly don't need that torque range, but we did need to talk about the dyno brake's 6,000 RPM limit. Looks like it will work out well if I bolt my drivetrain (clutch can, CrowerGlide clutch, in/out box, and inline QC box) to the engine first. I can create almost any desired ratio in the QC, so a 1.7:1 will allow running the engine to the [hoped-for] 10,000 RPM. The QC uses a pair of straight-cut spur gears, so power losses through it won't be a big concern. Actually, this will kill-2-birds-with-one-stone for me- I can experiment with clutch weights, instead of needing to do that on a race track. I'm hoping enough weight can be removed to delay full lockup to about 4,000 - 4,500 RPM.
Omigosh- 4,300 ft.lb. @ 6,000 RPM is more than 4,900 HP.
Watching dyno-testing of these "smoker" engines is awesome.
