> The pump is a Aermotive a1000 they claim the pump is good for 800 to the crank. All the supply lines were -10.

maybe that there is your problem??? claim 800 at crank, your at 612 whp. thats over 700 crank, 800 crank if you use 25% drivetrain loss.

i had the same pump as you. it died on the jack stands. never put 1 mile on it. magnet came loose in the housing, as it is epoxied to the housing wall. My pump would pump fuel, but not hold pressure. So i sent it back, they wanted 150 to fix it, i told them to keep it and got a bosch 044 pump.

another thought-- the gas your car was tuned on, and the gas you raced on, same thing? i.e. didnt tune on sunocco 110 then switch to vp at the track?

as for hard feelings, i have none. i dont even know where the car was tuned/or by who. just trying to trouble shoot for you.
