Dwayne,

I’m putting a N/A 20B in a = Lancair ES, so I’ll attempt to answer your questions.  My engine has = a mild street port, so I’m expecting 275-300hp.  Al G. had his N/A = 20B dyno’d at 275hp, if memory serves me correctly.  So, that should be a conservative number. 

 

Advantages of a turbo… more = hp at all altitudes.  Quieter exhaust, in fact you will likely not need a muffler if you use a turbo.  This offsets some of the additional = weight penalty that comes with a turbo.

 

Disadvantages of a turbo… = more complexity (tubo, intercooler, additional plumbing), more likely to = detonate, higher fuel burn, to name a few.  Also, you will be a bit of a = trail blazer when it comes to picking which turbo to use.  The only other = turbo 20B that I’m aware is Tom Parkes in AZ.  =   

 

My feeling on the turbo issue to go = with a peripheral-port instead.  PP is simpler, lighter, easier to = fabricate a manifold, etc.

 

No, Renesis parts won’t = work.  One of the 20B’s side housings in unique to the 20B.  This part = is only available for the 20B.  

 

Good = luck,

Greetings = all,

 

First time posting here so = I’ve got a couple of newby questions.

 

1)       = Does anyone know what HP to expect out of a = 20B?

2)       = Can someone explain the advantages / disadvantages to adding = turbo to a 20B?

3)       = Can a 3 rotor engine be built using Renesis = components?

 

Feel free to answer any and all and = thanks very much for your time!
