Nah. You're turning a smaller diameter, lower-mass,direct-drive prop than the 912, so the torque on the mounts is no more than the 912S with a 6-inch larger diameter prop. Also, the six cylinders and direct drive are smoother than the thigh-revving 912-series, because the 912 gear box shortens and sharpens the power pulses returned to the mounts trying to turn the large smooth rotating inertial mass of the prop, particularly at lower RPM. We've been flying our 3300 2S since 2003. It is the right engine for the job for as heavy as we load the plane and the altitudes we fly it, and it is especially well-suited for the 2SS. I've flown many Titans with a variety of power plants, including jumping between the 912's and Jabirus for concurrent flights, and you can feel the difference in vibration.

It would also need a 150VNE wing and wing mounts, and you'd want .090 windows so they don't push in or oil-can in flight. While the 3300 on the single place Tornado would be an absolute ball to fly at greater than 2000 FPM climb, it would also push it beyond the 150 VNE if not careful.

Just curious, but wouldn't the 3300, er, approach limits of the strength of the airframe in general on the I? Wouldn't the motor mounts be overstressed with the extra power and thrust etc?
One time a pilot ferrying an S/3300 home came through Santa Fe and I got to look at the combo up close. It reminded me of my old 5.0 mustang, with this big ol 302 shoehorned into that little bitty little car. It almost looked like the motor would twist off the frame soon as he advanced the throttle for takeoff.
Is the cage and overall airframe even able to handle all that power?
If I were rich, I'd have a single along with my SS but seems to me the most motor I'd ever want to put on it would be a 2200....
