Thinking of buying a Murphy Rebel kit for sale nearby. Got me to thinking about Rotax engines - which got me to thinking about Rotax engines for snowmobiles, which got me to thinking about the Rotax (BRP) 800r e-Tec engine - which is a compact little two-stroke.
Which got me to thinking about just how sorry the Rotax 912 is by comparison. You see the 800r is a state-of-the-art fuel-injected computer-lubricated 800cc two-stroke monster which kicks all of the 912's 1352 tiny little 4-stroke cc butts on a dyno and power-to-weight.
Unfortunately, it does not deliver this epic butt-kicking until about 7800 RPM - where it produces 159 hp and 107 ft-lbs of torque. A bit of a challenge for any PSRU.
It also puts itself to bed at the push of a button, and uses a tiny fraction of the oil of the 2-stroke Rotax 582 Aviation unit. As neither the 912/914 nor the 582 have changed much in 3 decades, I think it might just be time to think outside the 30-year box and make the 800r fly!
Any ideas?
(Another candidate would be the NASA "GAP Diesel" - another two-stoke - but one which we are unlikely to find attached to a recently-wrecked $9,000 snowmobile for 800 bucks.)
Just a thought
