- EngineThe main thing that separates Unleashed from the other Lancair aircraft is the engine. The Superior Air Parts XP-400SRE. For starters, this is NOT just a bored out IO-360. Far from it. The XP-400 has a 1/8″ lager bore and a 1/4″ longer stroke. It also shares the same roller cam system that other Superior XP-360 engines have, but with a different cam profile. Unleashed has the one and only SRE version of the 400. SRE (Superior Race Engineering) adds a few things that other engines do not. The biggest thing is 10:1 compression ratio and the cam profile to take advantage of the higher compression. Also, the XP-400SRE is rated for 3,400 rpm. I have yet to find a prop that will accept that rpm, unfortunately. Specs are as follows: Model: IO-400-J4AD3 SRE (XP-400SRE) Horsepower: 250+ Displacement: 400 cubic inches Number of cylinders: 4 Maximum RPM: 3,400 Bore x Stroke: 5.25” x 4.625” Compression Ratio: 10:1 Fuel: Avgas Weight: 310 lbs
