While dynoing my car this last weekend the air fuel ratio went to 17:1 as soon as we shot 150-hp at 3500 rpm . The dyno operator shut everything down in enough time that no engine damage occured. I have a walboro 190-lph in tank pump with factory lines, new fuel filter(high flow), and a kirban adj. fuel reg set to 40 psi ,24 pound inj.. Everything ran fine on 80 hp shot. On motor made 260 at the wheels on a mustang dynometer . The n2o kit is made by nitrous works and is obviously a wet kit. Im pretty sure the kit robbed the fuel pressure from the motor. So with all that said has anyone experimented with adding an in-line pump after the in-tank pump to boost flow/pressure available at the regulator.
