RV 14 with Superior XP-400 ?

jeffw@sc47 · #1 03-23-2017, 06:15 AM

Turned page of Finish Kit instructions and new section titled 'Install Engine'. Intending to go the SnF to get serious about buying engine; lots of choices and considerations.

I need to talk with any and all who have installed (or have decided to install) the Superior XP-400 on their RV 14 / A .

Have talked to two who have provided good information, want more.

If you PM or email me your contact phone and time to call, I will call.

I'm still years out from buying an engine, but I'm interested in this conversation too. The IO390 got such a bad reputation (self inflicted by Lycoming in my opinion) by pricing replacement cylinders as high as they did earlier before bringing them more in line with other engines, plus, I don't know if it is warranted or not, but I've heard of cooling problems, and issues with cracking due to the thin-walled cylinders, and there may be more issues. But I may still buy one simply because that's what Van's says around which the plane is designed. It would be nice to start seeing feedback from those who have the skills and courage to depart from the design engine to include the Superior 400 and Titan 370.

Those buying the XP-400, what advantages do you see in that engine?

Thanks

Be careful about the Superior Air Parts XP-400. They have been braking Crankshafts.

So far, Superior Air Parts is not willing to honor the warranty on the XP-400 crankshaft!

There was a thread over in the VAF engine section a while back that linked to the NTSB report about an 8A with the XP400 that had a crank break and subsequently crashed. I can no longer find that thread for further investigation. I was looking for information for a friend interested in learning more about this crank issue. . . weird.

You can find the thread if you search for "superior xp-400 safety alert site:vansairforce.com" in your favorite search engine. If you look at the cached version of the page, you can see the ntsb report link. Looks like the thread was deleted at some point.

So. . . I tried that. Two links of substance were produced. One linked to this website and said that thread was not available. The other came to this thread. That seems odd.

Wasn?t ?my? thread, nor did I participate in it, other than to read the information that was provided. I did not see the litigation discussions. I was interested in the topic from a safety of flight stand point for a couple of friends interested in purchasing this engine.
