    They aren’t the OEM nozzles for a 5ton, so they are ok.

    Finally found it: 0432191629 or 0432191642 fop Ppumped 300hp 6CT.

    progress on injector nozzles

    I quit doing injectors over a year ago. The bad thing with the nozzles in a 5 ton, is the size. They are too big, and dont atomize well at all. What I did find, is using some injectors from a newer 300hp 6CT, then playing around with the fuel rate will give a mild increase. Yet it'll burn much...

    So who has bumped the power on a 6CTA cummins

    You could go as far as removing the nut all together. The EGT will get a bit hot on the long pulls though.

    So who has bumped the power on a 6CTA cummins

    I have found the quickest way to get that screw out is to drill off just the head with a 1/4 drill bit. Then there should be enuf threads to grab with pliers or vise grips to take out. It's a coarse thread 4mm bolt, but cant remember the length(around 20mm long). There are quite a few with that...

    Ebay is the easiest. Just type in "dodge gov spring kit" in a search.

    I'd fly out there to go for a thrill ride.

    So who has bumped the power on a 6CTA cummins

    Because 97 and newer non-marine engines are electronic(ISC instead of 6CT). Higher than 300 are the marine engines usually, and they are already a really high power rating. And, 74M already explained the 5 ton's baby pump.

    It's the whole timing case, not really a mod, but swapping parts. It already has the hose in it for external oil feed.

    So who has bumped the power on a 6CTA cummins

    A colorado with a V8? Way Kool. I had a 97 dodge with similar mods as that guy you raced. It was a lot of fun. To run a Ppump off a dodge isn't too hard. The timing case, pump, lines, and injectors. You could get away with the old lines but they don't quite line up. The timing case can be...

    Cummins 6CTA8.3 Injection Timing

    Are you sure that's not 300-450KPA? That would put it at 45-60 psi, which is typical good fuel pressure.

    Go for it! Make sure the turbo stays under 40psi, and EGT in check. I would daily drive that!

    I wouldn't start at the max, unless you're empty all the time. I highly suggest you ease in to all that fuel. Start with it close to stock setting on the nuts, and work from there.

    These pumps don't have a fuel plate. The nuts on the back are the equivalent of sliding a plate forward. The gov springs are covered in that long thread "who has bumped up the power". You can tighten the stock ones, add washer shims, or get a Dodge gov spring set. The 3k kit will let it rev to...

    you should be clear sailing. Watch the pyro during hard pulls, but I doubt it'll get all that hot.

    It would shred everything in the drive train.

    progress on injector nozzles

    Just an approximation, 600hp. You would have to use the HX50 as the small turbo in a compound setup, and an HT4B sized bottom turbo.

    So who has bumped the power on a 6CTA cummins

    Yes, that is backwards. More fuel is more heat, which can come down with more good air. Good being a decently cool charge. A big problem I've noticed is in the injectors themselves. The pressure is so low they basically inject like a pee stream, not a fine mist. That's just one of the variables...

    A Ppump can certainly get it well over 400hp, even 600hp isnt too hard. The thing the 8.3 has going for it is the rpm range. The 8V92 is more of a novelty engine these days. Sure, an ISX will make 500hp more efficiently, it cant spin much past 2300. These can go to 4500....not that you should...

    To a mechanic that's a "it must be to factory spec" kind of guy, all of what I do is taboo. I'm sure he would flip out about these nozzles. Can't say that there is no way it will work with the Ppump plungers...There's always a way. Swapping to a Ppump is still Cummins spec, basically motor...
