Realistically, if this were a cup motor and I needed every possible advantage, I'd be looking at a dry sump system. But at the end of the day, what this thing needs to do is make possibly a couple of dozen passes at Bonneville and/or Gairdner reliably.
In Britain, race prepared MG/Rover K engines in 1.4 liter configurations under boost make in excess of 280 hp running the stock oil pump, and do so in road racing conditions that slop oil from one end of the oil pan the other. With the advantage of a shorter stroke with less windage than the longer stroke engine, along with a fairly deep sump, I'm thinking we should be fine as far as oiling is concerned.
While I recognize the advantages of a negative pressure in the block to produce horsepower, we took the record with 99.1 out of a tractor motor. Mark's convinced we can make ~125 with a high degree of reliability. I'm willing to put up with a little blow-by.
While the A-series 5-port was pushed to the limit, the K, with 16 valves, dohc and 5 main bearings,
provided I'm careful and smart when bolting it together, SHOULD be able to comfortably put out the kind of power we're looking for without having to get too tricked out.
I'm not looking to build the ultimate K series - just an optimal version designed for the task at hand.
I'll leave building the ultimate 1 liter motors to the Project '64 team and Stainless - which is my way of saying, "Congratulations, team Boxcar"!
