REFLECTOR: XP-400

[Chuck Jensen]

With the lighter weight of the XP-400 (and I assume it is), is that
equivalent to 260 or 270 hp out of a heavier IO-540 as far as aircraft
performance is concerned?

250HP out of a light 4 cylinder....WOW!  ....visions of scintillating
performance!

Heck, if props have trouble with the torque pulses from std 4 cylinder
Lycomings...how are they going to fair with 25%+ extra HP?

How's that new constant speed American prop going Rene?  Others?

Hi,

The XP400 is a superb choice for Velo SEFG/RG model builders, here is
part of the details from superior:

 http://www.xp-360.com/index.asp?content=15

About the XP-400 SRE Engine
XP-400 SRE Specifications
Model	IO-400
Displacement	400 cubic inches
Compression	10:1

Prop. Type	Constant-Speed

Horsepower	250 HP wtih 10:1

Superior's XP-400SRE Engine powered Scotty Germain's Unleashed Lancair
360 racer to over 258 mph at the 2006 Reno National Championship Air
Races! 

Unleash the racer in your airplane with Superior's race-proven XP-400SRE
Engine. Developed by Superior Racing Engineering, the 400 cubic inch
XP-400SRE delivers an amazing 250 horsepower. But there's more to the
XP-400SRE than brute power. Featuring all of Superior's industry-leading
components and technologies, it's an engine that will deliver reliable
and efficient performance whether you're racing or just flying around.

The XP-400SRE Engine features:

    * High-performance racing pistons
    * Specially designed racing camshaft
    * Proprietary Electro Slag Remelt (ESR) crankshaft
    * Angle-head Millennium CylindersT with bigger valves for better
breathing and better cooling
    * Build your own XP-400SRE at Superior's XP-Engine Build Center

Now 250HP from a slightly larger 4 cyl engine (based on the IO360/XP360)
is a good alternative to a 6 cyl IO540, obviously less weight, and
similar power, this is going to be my engine of choice if Deltahawk has
nothing available when I need an engine.

Steve.
