Brief Description: Our Barrett Precision Engine (BPA) comes to life !
oday I received a call from Allen, owner of Barrett Precision Engine, to let me know that our Lycoming IO-540-X engine, S/N BPE-11358 came alive today (Dec 3rd, 2013) on the dyno stand at Barrett. I don’t have the official paper work but he advised me the engine produced 301.93 HP @ 2701 RPM. Allen mentioned this is one of the best 9:1 compression Lyc IO-540 engines he has built. Regardless of the comment I am extremely happy with the results.
I originally had the EFII dual ignition system installed by Barrett so he could run the engine with the system. I believe this would be the first time Barrett has run the EFII system. Everything went fine until 2400 RPM. So the system was removed, mags put on and then run for initial break in. The EFII system is being sent back to Robert and they will give it a once over and verify if anything is amiss. Either it is a system issue or install issue but regardless I look forward to seeing the resolution to the problem soon. I was hoping Barrett would put the engine back on the stand with the EFII system installed so we can confirm proper operation and get a comparison against the mag run. I have confidence it’s not a system or install issue but likely a wire labeling issue or something that simple that caused possible crank sensors to be connected wrong. This is an assumption on my part…. We shall see…
