High Pressure Wrote:The little 3.9L 4bt is tagged at a whopping 105hp @ 2,500RPM... and 260 lbs/ft of torque @ 1,700RPM.

Hope to some day take it to around 180hp and 400 ftlbs of torque. I plan to stay with the Bosch VE pump but will change out the turbo or modify the current turbo for increased rotor speeds (boost pressure).

It won't be able to take on those Ford engines in a race...but it should provide low rpm torque.

you might be surprised at how fast they can be...I give a lot folks a run for the money in my 6000lb truck it's got a #5 fueling plate 240hp/600tqConfusedmokin:
