How does=20 the flying weight compare on the 20B with a lyco 360 for=20 example?

 

Thanks,

Dwayne,

I=92m = putting a N/A 20B=20 in a Lancair ES, so I=92ll attempt to answer your questions.  My = engine has=20 a mild street port, so I=92m expecting 275-300hp.  Al G. had his = N/A 20B=20 dyno=92d at 275hp, if memory serves me correctly.  So, that = should be a=20 conservative number. 

 

Advantages = of a=20 turbo=85 more hp at all altitudes.  Quieter exhaust, in fact you = will=20 likely not need a muffler if you use a turbo.  This offsets some = of the=20 additional weight penalty that comes with a=20 turbo.

 

Disadvantages of a=20 turbo=85 more complexity (tubo, intercooler, additional plumbing), = more likely=20 to detonate, higher fuel burn, to name a few.  Also, you will be = a bit of=20 a trail blazer when it comes to picking which turbo to use.  The = only=20 other turbo 20B that I=92m aware is Tom Parkes in AZ. =20   

 

My feeling = on the=20 turbo issue to go with a peripheral-port instead.  PP is simpler, = lighter, easier to fabricate a manifold, = etc.

 

No, Renesis = parts=20 won=92t work.  One of the 20B=92s side housings in unique to the = 20B. =20 This part is only available for the 20B. =  

 

Good=20 luck,

Greetings=20 all,

 

First time = posting=20 here so I=92ve got a couple of newby = questions.

 

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

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

3)      =20 Can a 3 = rotor engine=20 be built using Renesis components?

 

Feel free = to answer=20 any and all and thanks very much for your = time!
