Hi bobby
Pics didn't come th= rough will try again tonight.
Yes I had my map sensor attached now= at my throttle body after trying it atop the plenum , I seem to get better r= esolution at the tb now,I originally installed a mig welding tip with a .6 m= m hole in the centre as a restricter and that seemed to work well and keep a= balanced map between the 2 inlet pipes, I also made bell mths within my ple= num to enhance velocity,

Christian,

 

Thanks for the information and I=E2=80= =99m sure several of us are looking forward to a few pictures. Since your us= ing a single throttle body it must be installed before the plenum and not in= the runners close to the engine. Having a plenum after the throttle body sh= ould solve the MP port sensor problems others have experienced with the PP p= re-renesis engines.

Hi Bobby

No worries will try to post a couple of pictures.

 

So far I have played around with the throttle bodies, only trying single= ones ranging from original size to 65mm and now just fitted a 90mm.

I have attained approx only 300 rpm= differance on the rotary but seems to have a fair bit more torque.

I'm currently running a prince p tip= prop at 68" diameter 

= At this point I have had the p port for nearly 240hrs and running so sweet. T= otal engine time around 540.

Idles sits on around 1800-2000rpm happily.

As far as construction I built from memory 2 x 21 " runners t= hat route over the top of the engine to a 4 " plenum I built, I used the ori= ginal renises fuel injectors x 4 with 2 placed near the rotors and 2 x the p= lenum to infancy mixing.

At t= his point the chatter seems to have gone as I have dropped the timing back 3= deg, I won't know for sure until the engine is disassembled down the track,= but recently had the intake off for inspection and looks excellent inside, e= specially since I dropped my oil mixture rate.

I think personally that the rotary would love the small b= oost, I use a 3k elevation airstrip and single up in my rv7 can still get ai= rborne in around 450-500 mtrs and an average 29c day.

 

I had toyed up with the ideah at the beginning to put a small belt driv= en blower on but are quite happy with the p porting now and recommend it to e= veryone now for simplicity and power reasons.

 

Che= ers

 

Hope this helps

Christian,

I would love to learn more about your P= P Renesis. Any pictures you can share? 

 

Throttle body setup and location?

Single \ double throttle body?

Where are you monitoring manifold pressure? A= =E2=80=9CT=E2=80=9D installed between each rotor for average MP?

Warm\ cold Idle speeds?<= o:p>

Total hours on the PP?

Did you solve the rotor ho= using apex seal chatter?

Stock Renesis apex seals?

PP runner length?

 

I have a sp= are renesis I=E2=80=99m planning to turbo charge for 5#=E2=80=99s at takeoff= and normalized at cruise. A PP could potential allow less boost (2-3 #=E2=80= =99s) at takeoff and  safe normalization in cruise. Not sure about engi= ne life with PP and turbo. Although less boost and less heat could be a good= thing.

Hi Kelly,

Thanks for the update. It's great that a drive will be a= vailable again, but it's a shame he chose such a wide ratio. Hardly anyone w= ill want to operate the engine at 8k rpm, and even if they do, it will need a= larger diameter prop than most homebuilts can swing safely, due to ground c= learance issues. More typical operating rpms down in the 6k range mean sub-1= 800 prop rpm, which begs an even larger diameter prop.

Any chance he'= ll offer the more conventional 2.85? (Something closer to 2.5 would be even n= icer, to get prop rpm closer to the design point for most homebuilt airframe= /engine combos.)
