Carbureted Turbo 327 2.3 psi, 9.8 psi and Boost Spike
Before installing the fuel injection, the Innovative turbo 327 was set up with the Mighty Demon carburetor sealed in the Paxton carb enclosure. Initial attempts resulted in just 2.3 psi and 475 hp at 5,600 rpm. The culprit turned out to be two missing plugs in the carb bonnet and two oxygen sensors in the exhaust system before the turbo. Plugging these four holes resulted in much more boost, to the tune of 9.8 psi. This increased the power output to 675 hp, but the air/fuel mixture was starting to get lean near the top. One final run to 5,900 rpm resulted in 850 hp at over 15 psi, but the dyno fuel pump could not keep up with the fuel demand of the turbo motor. We never got a clean run (even at low boost) to 7,000 rpm. View Related Article
