Big Rigs & SemisDiscussion of Diesels Used for Transportation of Goods
Hello again. A friend of mine has a service truck with a mechanical 8.3 Cummins mated to an allison automatic. I am guessing it weighs about 15-18,000lbs. It governs out at about 65 mph. I am almost positive it has the p7100 pump. How is ... JOIN NOW TO REMOVE TRACER
Hello again. A friend of mine has a service truck with a mechanical 8.3 Cummins mated to an allison automatic. I am guessing it weighs about 15-18,000lbs. It governs out at about 65 mph. I am almost positive it has the p7100 pump. How is the best way to go about giving it more power. Would you recommend sliding the fuel plate (forward I think), grinding on the fuel plate, buying a fuel plate, or some other means? Would a fuel plate work from a 5.9 cummins, probably not? I am guessing the factory hp is on the low end, maybe 225, and I can check. He wants to keep it simple, and I don't think he will need a pyrometer as it is an automatic, doesn't pull trailers, and doesn't want to bomb it. Thanks for the advice. Eddie
outch 225hp.. my buddy just bought a boat with a 8.3 in it.
i think it's like 350hp... i'm pretty sure his has the p7100 i didn't get a real close look.
being a boat it already has a 7" exhaust no cat and bhaf
i tried to get him to hop it up a bit... he's to much of a wuss
Here's a couple videos of an F800 with a hopped up 8.3 in it. It has marine injectors and a #0 fuel plate(both from me), 3k gov springs, and an HX50 turbo. It's going from about 20mph to 65. He says it was not even close to full pedal(about half way to the floor). Plus, was only shifting at 2300rpm.
Sorry, you have to copy & paste.
