Good after noon all, I have a 97 ford f800 with a 12v 5.9 Cummings in it and I need more power. I turned an old service truck into a blasting rig and the added weight is lugging it down. Does any one have any suggestion as to what I can try first before upgrading my turbo and injectors? If I do need to upgrade my injectors and turbo, is there any suggestions on brand and model? Thanks in advance.

 

which injection pump does it have?

I assume the p7100 pump, and if so: add a fuel plate and dial the timing screw to around 22* or so.

A boost elbow on the HX35 will allow it to build more boost as well.

You will want gauges on it to monitor EGT's and boost.

 

Thanks jigabop. It is the P7100. I adjusted the fuel plate and turned the smoke nut about 3 clicks and it added some power. I'm not sure what the HX35 is or how to do the 22 timing but I can read up on it. Thanks again for the input.

 

hx35 = the turbocharger.

a boost elbow is a small orfice you can get to replace the stock one that goes between the compressor housing and the boost signal hose which connects to the waste gate actuator.

the boost elbow has a set screw in it to allow you to limit the amount of air flow through that signal hose so you can use it to delay the waste gate opening to allow higher boost levels.

35psi is the max boost you want to see out of a hx35 turbo before it is out of its efficiency range and just being overdriven.
