According to computer models (JetSpec 2.0) The engines alone should make roughly 133lbs. of thrust. Water injection does wonders on these engines too, keeping operating temperatures low and offering a significant increase in output power. No one has logged how much more power is made by water injection, but military experience shows that it could be over 50% increase.
Power delivery will be done similarly to turbo compounding, the thrust of both engines will be collected and used to spool up a turbine hooked to a gear reduction to amplify torque and bring RPMs into working limits of the drivetrain while final drive is delivered through a snowmobile clutch to the front sprocket. I will gear it as high as i can for Bonneville without running EGTs too high, as that is the leading cause of homemade turbine failure.
As far as horsepower, I'm not sure how to convert to it from thrust, but there should be roughly 200lbs of thrust when everything is running right on a motor significantly lighter than the stock R6 powere plant. As far as goal for top speed goes, the Omega/APS record as of 2009 is 176.3mph. My current goal is 180, but we'll see what happens this year. Of course, i wouldn't be opposed to going 200!
