Someone mentioned this is like a reality TV show. Given how many people are interested in what he’s doing, and the ratio of time he must spend making videos vs making an airplane, maybe this is a plausible pivot for him. He just needs to get an aeronautical engineer involved so we can hear him argue his unique take on physics. Ron Howard could narrate.

Better yet: The Peter and Jerry Show!


You can blow the budget: only one episode will be made.

Hmmm, someone should tell him he could fill those tanks with ice for a big win.

No, not the tanks Abram, the whole freakin' nose compartment! Pack ice around the added coolant tanks to chill them. That accomplishes multiple things that Peter would generally look for:

  • Provide a temporary improvement in engine cooling without any long term benefit.
  • Be a non-production worthy change that mostly wastes time.
  • Increase gross weight tremendously.
  • Provide a continually changing CG as the ice melts, or if the compartment is sealed, provide a sloshing, moving center of gravity.

Does he read BT? Somebody needs to tell him.

I love that despite all of our differences, we can all come together to make fun of Peter. :bud:

He's the great unifier.

I just hope he hasn't done any good with the plumbing tank install, so that we can see the next idea, which most certainly will not focus on rejecting any heat by conventional means.

Please someone post on his YouTube that he has 185 pages of our comments to read... could be a good episode on peters channel.... reading out comments and his opinion of them!

More looking at graphs, plus the addition of a giant trim tab to get the left wing down. He justifies it by saying that these are used all the time on production aircraft.

The Homebuilt forums hit 383 before it got locked by the mods...but maybe we'll be able to catch up now. :rofl:

It amazes me that taking off a turbo as some Audi engineer suggested is just too much work.

The highlighted part of your statement explains why Peter won't go there.

I chuckled about painting the tanks black for the radiative cooling effect — into his enclosed nose compartment. A BTU here, a BTU there, pretty soon it‘ll add up!

Hmmm, someone should tell him he could fill those tanks with ice for a big win.

I'm surprised he hasn't tried feeding the A/C cooled air into the engine somehow. :D

The a/c condenser, IIRC, is third in line for cooling air after the turbo aftercooler and the engine radiator. I’d put money on the a/c being functionally inop at power settings above 50% due to all the heat pouring on the condenser from the other heat exchangers.

I just watched the video. Let me get this straight.... he can make it 90 seconds before the TIT hits over 1650°..... hmmmm. I’m not an engineer but I can tell you that Peter doesn’t have a clue! His engine won’t make it to TBO because his turbos won’t make it to 50 hours......

Also, he has finally admitted that his radiator and intercooler setup up is wrong. I don't know how long people have been trying to tell him that. I really don't understand his end game here. He knows it's only going to give him a few more minutes before it overheats. Until you pull all that crap apart and fix the airflow issue, it's just going to overheat every time.

The stacked heat exchangers are far from ideal. But at least as big of an issue is too much heat. His mismatched, mis-plumbed turbos, even with the waste gate tinkering, are more heat generators than HP generators. It’s been over a month since The Great White Whale staggered into the air and he’s still messing with things that won’t solve problems. One turbo could have been removed and the induction and exhaust plumbing modified in a week or ten days and that would have resulted in more HP and less heat, which in turn would mean less cooling required.

You have experts that have done auto conversations, built aircraft and engineers that work with the TDI trying to post suggestions to his YouTube. He either bans them, dismisses their comments or doesn’t care “not a problem’ type responses to them. The guy thinks he’s the smartest person in the room and listens to nothing.

He posted a comment that he plans on fixing the cooling issues once he gets out to California to start production. It’s kind of scary this level of oblivion.

I bet he is going to find that he needs more right rudder!!!!
