110hp, 54kg, 1000hr TBO- Simonini Victor 2 super. Anyone with experience?

[Rotax Rick]

The Simonini Victor 2 Super is a 95 hp engine with the Mono Exhaust. The TBO is 450 Hrs. I am the USA Dealer & maintenance facility. It has 801 cc's.   The Rotax 582 was made for 8200 rpm but they made an exhaust that would work at lower rpms to get a sooth power band without flat spots. Simonini lowered the port hight for 6200 max rpms so you get a lot longer powder stroke & globs of torque at lower rpm's. Also they use Reed valves instead or the RV disc thats separated by an oil cavity to lube the RV shaft , gear, bearings & had the water pump impeller on the other side.  Simonini has an external water pump thats belt driven & that makes for a shorter & much stronger crankshaft, plus no internal oil / coolant leaks & it is easily swapped out. Simonini uses much improved flat slide carbs, and they  use the same Ducati dual ignition system used by Rotax.  I had a customer with one of my 92hp 670's who switch to a Victor 2 Super with the dual 110 exhaust & he said it smoked the 670. The Victor 2 Super uses the same engine mount as a Rotax 503 or 582. You can also limit the rpm to make only 52hp or 65hp if concerned about the extra power & with EVERYTHING the Victor weights only 115 lbs. To clear up some of the above comments on the 618, it was the very best 2 stroke liquid cooled  Aircraft engine that was ever built.  I can convert a 618 into a 666 that will smoke the 670. They also have a larger crank pin than the 670's have. The problem was Rotax kept the same .003 piston to cylinder clearance. The 618 used the same piston as a 582 but had 78hp so cold seizures was a problem if not operated CORRECTLY !!!!  They had the exact same cylinder head thats on the Blue Head 582 to try to prevent the cold seizure issue. Rotax dropped the 618 because it was to close in power to the 912 & Rotax knew the 912 was the future.  Well thats my 2 cents. Rotax Rick
