I recently completed a 6cyl conversion in my 79 Jeep J20 truck. Motor was out of a 92 Dodge 2wd. I put an NV4500 behind the motor. The truck drives good down the road engine seems to run fine, however it will only boost around 11 psi maybe 13 if i whined it out in 3rd or 4th gear. It appears as if my pump has not been tweaked at all. It will not put out any black smoke while driving. Just sitting there idling if I snap the throttle it will put out a small black puff. Saturday i turned the smoke screw about 2.5 turns the truck felt a little bit peppier but still not boosting any higher and no increase of smoke. I have checked for air leaks but havent found any yet, short of pulling the intercooler out.
just driving the truck around the power seems ok, but i put my TJ behind it on my trailer and it felt like a dog in 4th and 5th gear.
Any ideas? I will be changing the fuel filter out one day this week.
thanks joe
