Bob, I'm sorry. I'm Aron. Meant to include that in the last post. Yes, I'm right there with you on the different type of "hit" you get with the types of boost devices. While a turbo or centrifugal blower is a softer hit, it is in not as limited at the upper end in the way positive displacement units are. I could run double the boost if I chose to, and I don't have to change pulleys and add more friction to do it. But I can't. Its still a Pontiac engine, and the head bolt spacing is not sufficient for long term high boost. It does nicely though at 15 psi, and I usually just run it at 10...which is still over 1000 hp and in the neighborhood of 875 ft lbs torque.
Forgot to mention. Its set up with a gated road race oil pan and a 3 qt oil accumulator with a 2 qt racing filter. All told with the oil cooler in line 13 qts oil.
And that lightweight car of yours with a 427 small block is a serious machine.
