dogg rescue Posted May 7, 2015 Share Posted May 7, 2015 Looking to get a little more power out of our '86 superliner (4v) it runs ok but our 300's can out pull it. The anti-puff has been disabled,the pump has been rebuilt. I don't want to shorten it's life span, and also not so concerned with mileage on this one. Does anyone know what injectors, turbo to use, how about pump settings, and timing? Any help would be great.

theakerstwo Posted May 7, 2015 Share Posted May 7, 2015 You can get some more power from it but it does shorten its life.Just like a mule pulling a heavy wagon all of its life vers just walking around eating grass and making grass biscuits.

chief doug Posted May 7, 2015 Share Posted May 7, 2015 before you go any farther, when was the last time the valves were adjusted. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/39942-more-power-from-an-e-6-350/#findComment-289112 Share on other sites More sharing options...
Timmyb Posted May 7, 2015 Share Posted May 7, 2015 Sounds to me like you want it to perform as it should? What boost you getting? Maybe look for any leaks. Also is your throttle linkage worn? 2 Quote Link to comment https://www.bigmacktrucks.com/topic/39942-more-power-from-an-e-6-350/#findComment-289125 Share on other sites More sharing options...
gearhead204 Posted May 8, 2015 Share Posted May 8, 2015 are you reaching governed rpm no load? IF NOT ADJUST CABLE OR LINKAGE. how much boost will it build under load? if under 35 lbs check cooler and or hoses. have the valves adjusted and pump timing checked.

dogg rescue Posted May 8, 2015 Author Share Posted May 8, 2015 The valves were adjusted a while back, it seemed to help, but not much. There is no turbo leaks, throttle linkage/cable all tight. It reaches governd speed with no load on the engine, 1900 rpm. I will be installing a boost gauge to get a reading. The company this truck came from was known for having the most gutless marks around.

Lmackattack Posted May 8, 2015 Share Posted May 8, 2015 1900 no load.....you have the dreaded low rpm motor?You can have the pump recalibrated to a 2100 rpm spec and that should give you some more powere. I would have them bump up the fuel 10-15% at the same time.

mrsmackpaul Posted May 8, 2015 Share Posted May 8, 2015 have you done a compression test even if it runs fine if the motor has done lots of idling in its life it might just need a valve grind Paul Quote Link to comment https://www.bigmacktrucks.com/topic/39942-more-power-from-an-e-6-350/#findComment-289177 Share on other sites More sharing options...
