Don't see it.
Don't see it.
These folks really gave the Raptor a bad review
Starts at :30 mark
Don't think that video says the engine is "packed up." It might be at this point but this video seems to be all about all the cooling mods and tuning mods he is going to do. If the engine is "packed up" then it should be removed and inspected.
At the end of the video he says his car's engine crapped out and that due to that he needed to find new vehicle and would be delayed on Raptor work. He was talking about his automobile, not the Raptor's engine.Don't think that video says the engine is "packed up."

OK, a study in somewhat vague vague and misconstrued references on my part. The Raptor engine is a car engine and it is an Audi. Had no idea PM drove an Audi as well. Noted.At the end of the video he says his car's engine crapped out and that due to that he needed to find new vehicle and would be delayed on Raptor work.

Its his car engine that packed up, it's also an AUDI,hence my comment regarding the use of a car engine in an aircraft.Don't think that video says the engine is "packed up."

Actually I believe a VW or Audi engineer did comment telling him the same thing I told him 2 years ago about the turbo mismatch. He's chosen to ignore the advice and reasoning. That word hubris comes up again... Yesterday he labelled knowledgeable engine guys and engineers who tried to help him "know-it-alls".Has the Audi car company been made aware of this project, and the use of one of their engines? If Peter could have at least basic access to their engineering people, some of the answers to the engine issues could be presented to him in a way that he might accept.
Meaning, if any HBA member (no matter how educated or qualified) called him and tried to explain why he needs to remove one of the turbos... based on what I have read so far he might not care. But if the Audi engineers tell him that he needs to remove a turbo, maybe he would accept their level of knowledge more easily.
This of course assumes that the Audi company would be willing to help, based on the idea that preventing one of their engines from being implicated in a disaster news story is worth the time, risk, and liability of even talking to him.
It appears from the Raptor YT Videos that one of the actual designers of his engine has offered verbal assistance to solve the power and cooling issues, & as I understand it, (to date,) PM has not accepted any help in that area. I also worry as to his 'solution' ref the vortex issue within the wheel wells. I would have thought that even a low hour PPL would have a basic understanding of aerodynamics, and by fitting 'stall breaker strips' , instead of covering the wheel openings would be obvious ??? I gather he is now going the cover the openings with alloy sheet and duct tape !!!, why not a foam block and tape, (much less damage to the prop when it falls off). Try as I might not to follow anymore the ongoing saga of this flawed project, it seems that like a moth to a flame, I, and many others just can't wonder where the next ill conceived solution to self inflicted poor design ideas will lead. Going back to the wheel well issue??? if a proper Raptor was actually built, then the u/c would fill the wells within seconds of leaving terra-firma, so what's the problem !!!!.Has the Audi car company been made aware of this project, and the use of one of their engines on the Raptor?

What every other test pilot has done on this project.I don't know what test pilots do about the excess gear drag (if anything) on an underpowered design.
IIRC, the Vickers Vimy replica ~20 years back originally had BMW engines, with BMW support. The company pulled that support, and the Vimy folks were forced to find another engine.I wouldn't think that Audi would want anything to do with the project- one of their engines modified by someone with no engine, turbo or EFI background, attached to a homebuilt aircraft that he designed also with no background in AE, structures or systems design.
And, actually, this thread has suffered severe drift. The title refers to an "ANN Network Video" and no one is talking about THAT anymore. On that basis alone, it should be merged with the original Raptor thread, or a new thread should be started referencing the appropriate Raptor video.I suggest that this thread be merged with the original Raptor thread. The point has been made, and it would be nice to have all the comments quarantined in one thread.
While that seems very likely to me as well, it's probably best if we don't speculate about the business aspects here without any concrete information.Nor can he afford to deliver kits at the advertised price without losing several hundred thousand dollars per kit.
