Hi Bobby
No worries will try to post a= couple of pictures.

So far I have played around w= ith 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.<= /div>
I'm currently running a prince p tip prop at 68" diamete= r=C2=A0
At this point I have had the p port for nearly 240hrs and= running so sweet. Total engine time around 540.
Idles sits on ar= ound 1800-2000rpm happily.
As far as construction I built from me= mory 2 x 21 " runners that route over the top of the engine to a 4 &qu= ot; plenum I built, I used the original renises fuel injectors x 4 with 2 p= laced near the rotors and 2 x the plenum to infancy mixing.
At th= is 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 t= rack, but recently had the intake off for inspection and looks excellent in= side, especially since I dropped my oil mixture rate.
I think per= sonally that the rotary would love the small boost, I use a 3k elevation ai= rstrip and single up in my rv7 can still get airborne in around 450-500 mtr= s and an average 29c day.

I had toyed up with the = ideah at the beginning to put a small belt driven blower on but are quite h= appy with the p porting now and recommend it to everyone now for simplicity= and power reasons.

Cheers

Hope this helps

Throttle body setup and loc= ation?

Did you solve the rotor housing a= pex seal chatter?

Stock Renesis apex seals?

PP runner length?

Hi Kelly,
=
Thanks for the update. It's great that a drive will be available ag= ain, but it's a shame he chose such a wide ratio. Hardly anyone will wa= nt to operate the engine at 8k rpm, and even if they do, it will need a lar= ger diameter prop than most homebuilts can swing safely, due to ground clea= rance issues. More typical operating rpms down in the 6k range mean sub-180= 0 prop rpm, which begs an even larger diameter prop.

Any chance he&#= 39;ll offer the more conventional 2.85? (Something closer to 2.5 would be e= ven nicer, to get prop rpm closer to the design point for most homebuilt ai= rframe/engine combos.)

Charlie
