Did two dyno passes yesterday with the Kenne Bell. 42's in place, no boost-a-pump, 11 psi. We dumped in a fair amount of fuel, backed off the spark, and did a pass. Off the chart rich (below 10:1) all the way up to 6200 rpm. Second pass, leaned it up a bit. Same results A/F results, with more hp/tq.

Hypothesis:

Bone stock fuel system could safely support up to 13 psi. With the boost-a-pump, I beleive a bit more boost can be added without over taxing the 42's.

Only one way to find out for sure though, more results to come!!

Isn't 42 lb at the pressure most companies rate them at, and 38(39?) for the pressure Ford runs them at?
