Thanks for the compliment. The Hex bolts are tungsten counter weights and they do reduce crank loading.
There are actually several flavors of compression ratio and I match these to suit the original cam profiles we have.

Default 409

First one is in an overgrown Cub, installer said it is "turboprop smooth". Second one is headed for an RV-8 in December. Next?

I just took delivery of one that was built for me by Aero Sport Power. Still in the crate and will probably be several months before I put it on the Bearhawk I'm building.

A friend of mine races sport class biplanes and is begging me to become and 'sponsor' and let him break the engine in for me...

Looks like ECI 409 version got the axe, Superior has the 408 back. ??

They have the original XP-400 back. An engine I have 300 hours on and 3 Reno Air Races. Barrett Precision Engines is the first authorized XP-400 build shop.

Where did you hear that ECI has discontinued the 409? (Not that they've delivered one...)
