Ive been messing with these cars for 20 years and have had 8 Turbo Buicks and 1 Turbo T/A. This is the one i really wanna dial in..
Someone enlighten me on the newer turbos..Thank you
NyBlankets said:The import guys make ridiculous hp with the 67s, they run 40+lb of boost though. The newer turbos are more efficient but one would probably have to push it beyond 30lbs to see any kind of benefit over the older style 67s. I've seen dyno charts where the new billet turbos make over 100hp vs the old designs. Again these guys run well over 30lb of boost.

Trying to grasp the concept Brian, please bear with me. Lets say for arguments sake I'm running a 6765 JB cast wheel turbo on an engine that could easily handle 90lb of air. I then upgrade to a 6766 JB billet and keep the boost level the same (as an example, 28lb.), would they make the same HP or would the 6766 show a noticeable gain? Am I correct to believe that unless you move out of the 6765 turbo efficiency range they would make the same power?
Not only are you very knowledgeable, but have the patience and ability to explain the physics behind it. Well done as usual!I can't say for sure what the 66 ex wheel will flow ....................
