Granted this was on a dyno (static, no acceleration to overcome)But one day last year I was testing a 572 Indy engine. It should make around 900 HP. after a warm up and short pull I made a full pull to 7000. Timing was backed off and it made 875 but the BSFC got weird around 6700. I have a two fuel pumps on my dyno fuel cell. They each feed into a fuel log that feeds the engine being tested. A simple 90 degee valve and flip a switch and I can change from a Holley blue to Magnafuel 500 fuel pump. OOOPS,I didn't change pumps and I was testing with a HOLLEY BLUE PUMP and reg! 875 HP thru a blue pump and std BS regulator. Bob George is right, I always want to over bulid the fuel system but is pretty amazing what some of the basic stuff can do!
