Successful Long EZ Supercharged Rotary

[BLUE MAX]

Today I received from Tom Jordan, a Long EZ flyer, some pictures of his SuperCharged Long EZ. I hope he does'nt mind that I posted his pictures. Tom so far has flown about 10 hours with his 275 horse power super charged rotary engine with no cooling problems. He uses a P-51 scoop for cooling. He had fabricated 2 inline oil coolers right in front of the airflow of his scoop. He says his cooling is not an issue.

some more pics

Tom,
Thanks for posting the pics. I have two that someone posted elswhere. I am always interested in the rotary in a long EZ. Not too many of them around.

Joe,

I'm sticking one in mine. I ordered my motor mount from Fred Breese about 2 weeks ago. Looks promising!!!

I found another pic for the side view.

Very nice. 275 horses must make a LongEZ get up and go. A supercharger too! How on earth did he get it all under the cowl??? Any chance you could get Tom to join here and tell us his story?

I would be most defenitly interested in some info on his supercharger since that is my dirrection of travel!

Pretty cool. Can he do torque rolls vertically from SL to 10,000 feet?

That looks a little like the Eaton M62 I put on my old Civic, except mine was reverse rotation

The ducting looks clean...I like the fully wrapped exhaust. That should help keep everything nice and cool. I'll be looking forward to the 50 and 100 hour reports on the configuration. The projected budget for my LEZ just doesn't have room for a Lycosaurus (yet), and man, for the weight, 275HP would be amazing.

edit: It looks like he intercooled it, and has a boost adjustment system (the aluminum box on the manifold side of the blower, with the scat going off to the reverse NACA on the bottom of the cowl, looks like it can select between normal intake air and the boosted charge) It'd be pretty cool if the intake tube that runs over the top of the engine had been mandrel bent and a little larger, but it's easy to Monday morning quarterback something like this. I wish him all the luck in the world with this.

Eaton was on my list of superchargers to review, but I had not sized one up yet.

This makes it easier.

Go baby go!!!!

RG too. It hard to tell from the pictures the size of scoops. Are those scoops under wings?

Fully wrapped exhausts do keep the undercowl temps lower, however, it is my understanding that they keep the exhaust system much hotter. The Rotary exhaust is, by nature hotter than an equivalent boing-boinger. In my Midwest rotary (notron), because of this, they specifically specified that wrapping not be done. The exhaust plumbing was also of much heaver gauge stainless than the dinosaurs. Check your exhaust system well and frequently.

Retracts and 275 hp on a Long... zoom zoom

[BLUE MAX]

I will call Tom and see if he can send me scoop pictures and his oil cooler, radiator arrangement under the engine. I will ask him for a reports too.

[dpaton]

I totally missed the e-racer style retracts. Zoom zoom is right!

As for wrapping the exhaust, there are a number of high-temp steel alloys that can stand the heat (1900F sometimes) produced by a rotary, but they're not cheap. I suppose it would depend a lot on the cooling available in the engine compartment, relative airflow, etc. I'll worry about that later. By then, y'all should have it solved

high temp - 321, inconel, and hastaloy.

304 will work, for that matter so will cast iren and mild steel. just that the mild steel will wear out sooner than the 304 and the cast iren, welllllllll, thats just heavy stuff

Don't know if you NEED it for supercharged, is the rotor nonturboed have exhaust that is that hot?
