wow! double o-ringed block!!
It's weirder than that too. I have no idea what compression ratio was used, until I can find the rods, measure the crank, figure out what gasket was used ...
XXXX errrt! no head gasket could be used! the O-rings would not work! Duh! The sealant is for the water jacket and oil. Umm I knew that, right.
I'll do the math later, but here's a quickie: There's a turbo-selection nomograph in the MacInnes book. Using what I do know about this motor (182 ci, 640 hp, TE06 turbo) and assuming 7000 rpm, the boost required to acheive 640hp is literally off the chart -- far more than 30 psi. Interpolating, probably close to 50 psi.
[I said earlier there were TWO TE06's on the Indy motor. That's wrong. I don't know where I got that. Though I took crappy pictures of the Indy motor there's clearly only one. Duh. My bad.]
50psi doesn't make sense then. A TE06 will do a pressure ratio of 3.0 at the top of the compressor map top efficiency, and 50 psi would be about 4.3 (I think). r=3.0 would be about 30psi, and 182ci with 30 psi boost is only! 550hp. I got "640hp" from the web...
That puts flat-out peak air flow around 50 lbs/min consistent with 550 hp, or 3 hp/cu in.
At 8000rpm, you can do this with 25 lbs boost, but then the TE06 has run out of poop.
There was no intercooler, so the air goes in as hot as a blowtorch.
Valve lift is probably over .500". The block has valve reliefs .25" deep, both int and exh. The top ring is .3125" down from the crown. I estimate the valve could open about .6" without hitting anything (I know those numbers don't add up). But both heads have shaft-rockers, I wouldn't think you could get a half-inch lift at the valve with those, the geometry would get wierd at the extremes, right?
