Hey! Way to go! Dennis.
 
Sounds to me you have had a good 60 hours to = prove the air=20 worthiness of your installation.   Since the Hushmaster has = been good=20 for 40 hours on my old turbo block 13B with the strongest exhaust = pulses, I=20 suspect it will last a good long time on your Renesis.
 
Great looking airframe and paint job as = well.  Hope=20 you make it to Sun & Fun!

60 Hour Inspection : RV-7A, RX-8 Renesis = engine, James=20 Rotary Cowl, Radiators under engine

As of January 08 I've flown = my=20 Renesis powered RV-7A about 60 hours.  At the 60 hour mark I did = a=20 detailed inspection of the intake and exhaust systems as well as = everything=20 else under the cowl.
I found no cracks or other problems with the = exhaust=20 system!!  The heat shield between the muffler and the left cowl = had lost=20 one attachment screw- no big deal.  Attached are pictures of the=20 exhaust.  I use a stock RX-8 exhaust manifold - a 4 in dia. X = approx. 6=20 inch long swirl pipe(see third picture) to redirect the exhaust from = the front=20 to the rear of the  plane and a Flowmaster Hushpower Resonator = (PN -=20 12512400) as the exhaust muffler.  Everyone who hears the = airplane fly=20 comments on how quiet the engine is - neighbors call it the Stealth = Rotary=20 RV!  It is super quiet compared to my neighbors 180 Lycom.=20 RV-7A.   I don't know if the Flowmaster muffler will = withstand the=20 exhaust pulses from the RX-7 engine rotors but I feel confident the = muffler=20 will work with the Renesis.  Mark Steitle with his 20 B engine = and=20 Flowmaster resonator will have first hand knowledge soon!

I had = previously found that one EGT probe extension wire melted - it was = about 8=20 inches from the exhaust system.  The probe wires leads = were not=20 damaged but the extension thermocouple wire from A/S had = insulation=20 that melted from the exhaust heat.  I have rerouted the extension = wire to=20 keep it away from the exhaust.

There were no problems with the = intake=20 system. It is fabricated  using part of the RX-8 manifold  = and a=20 home-made intake plenum.  I used the stock injectors, fuel rails = and=20 injector locations.  The fuel pulse damper was removed! (Pictures = in next=20 E-Mail)

I did find several very small oil leaks in the casting = of the=20 PSRU.  I'll confer with Tracy as to how to address these. =

I used=20 the James Rotary Cowl - same one as the Power Sport rotary used - = mounted my=20 oil and water radiators underneath the engine, bought an engine = from a=20 wrecked RX-8  with less than 10,000 miles on it.  The engine = was not=20 disassembled.   I also used (with some modifications) the = exhaust,=20 intake, fuel injection parts, spark plugs, plug wires, coils, 100 amp=20 alternator, oil injecton with Richards adaptor,  water pump and = water=20 outlet system with the thermostat removed. (See attached = pictures)

I=20 will be adding a cowl flap to keep the oil and water temps. cooler in = the=20 hottest summer and warmer in the coldest winter = temperatures.

My prop=20 is a Catto 76 in. dia X 88 in. pitch and my max. cruise rpm is only=20 6200.  I am over- propped for the HP currently being = produced.  This=20 does allow me to cruise at rpms around 5400 when I want to go fairly = fast and=20 keep fuel flow down.

My success so far is in large part due to the = contributions others have made to my project by posting - their = successes and=20 failures, thoughts, knowledge, suggestions  and references to = other=20 sources - to this list!!!

A Special "Thank You" to Ed Anderson, = Lynn=20 Hanover, Al Gietzen and all the other contributors  for all the = great=20 knowledge they bring to the rotary group!
