I just used the carb
examples of where throttles are generally located in turbo charger systems.
In front of the compressor or behind the compressor. What
say you?

Paul, You are quite correct that most carburetor systems place the carb before 
or "upwind" of the compressor section. My only point was that the upwind position 
allows a more standard carb type. The compressor seal must tolerate fuel though. 
While drive-ability is not a problem for us, most blow through or "downwind" 
systems work better if properly designed. I like your positioning choice. 
The best carbureted system I have ever seen is on the Yamaha 650 turbo motorcycle. 
It isn't the most powerful I've seen, but is the best all-around carb system I've 
ever seen. They use a really neat idea to seal the throttle shafts. The slide 
throttle idea you have is identical to how Kehin did the flat slide in their 
carbs. The little wheels prevent sticking well. It should work real well. 
I would think that you needn't cast it but could cut it out on your "CCM"! Bill Jepson
