Twin Turbo 383 questions

I love this type of thread !! 1400 hp !! well there are very simple realities that often get forgotten. Regardless the type of intake charge boost used, the motor is still an air pump.. There are a couple volumetric considerations, but as a rule, 1 atmoshphere (14lb ) = 50 % horsepower increase. So your 1400 hp dream mobile would need to make 900 hp or so without a turbo... Which is fine, but probably means he has a fortune in that motor. This thread is about making 800 out of a 383.. a good running 383 is making around 400 hp so you could get 600 hp out of 14 lbs of boost.. I run 16lb ( blower
- D1SC ) through a 474 and make 790 hp.. I could probably get another 50 hp if I changed the very mild cam profile im running, but I like idling at 700 rpm. Just a reality check. Fun thread.
