    My biggest thing is tools. If I go mechanical pump. I have nothing to time it nor the knowledge to do so. Plus I'd need the cable and pedal possibly to convert to manual pump.

    That' exactly my problem. Yes I know there' a ton of power to be made by going mechanical. But there' also a lot of headaches that can occur and realistically the shop where I work on the truck is 70 miles from my place cause of the damn leasing center. So that leaves 70 miles of praying...

    I know it' not cheap. Realistically I know the 6.5l will only tickle the surface of what a moderate dmax or Cummins can make. But to go to dyno events or the sled pulls. I do want it to be interesting and show that the old girl still has some power.

    Nope. The tires and rims will probably get ditched in favor of 35s the 37s ride like shit and are super loud.

    I' not sure I can do a signature since I'm on my phone. I've searched the options and can' find anything

    Don' get me wrong. Yes we can have quick trucks, but quick is the key word. And I should not have said shit power but comparing it to a modern diesel like my buddies 6.7l with moderate work. Yea it's depressing . Realistically how much power can one make with the ds4 pump. I know most people...

    Turbo is a s366 with 6+6 billet wheel with a t3 .82 open scroll housing. Exhaust is nothing special, diamond eye crossover, downpipe modified with a 90 and 3 8nch vband to bolt to the s366 and their 4 inch exhaust without a muffler

    The truck is a 98 sierra 3500. Used to be a dually. I don' remember honestly if it was a spin on or not.

    W What do you mean filling out signature. I filled out the information section in my profile.

    Yes I know I'm new here. But I do know the ford Idi guys run very low pop pressures because they think the fuel actually makes it out of the precup and doesn't burn entirely making more power. Hence why my idea came up of ditching a precup design all together, maybe running 2500psi pop...

    I' running stock cooling system. I haven't had an issue yet but I also don't tow. I already have a fluid damper. Otherwise peformance is a s366. Ftb mod. Lift pump, and kojo tune.

    I know coatings can be applied. I was thinking of redesigning the precup simply because I don' know why it can' be improved. If the fuel is injected into the cylinder where the air is already swirling I'd think it would help combustion instead. Granted all of that would occur faster then we can...

    What would happen if we took out the 3 cups and instead machines them to have the same volume but have the injector spray against the pre cup into the cylinder instead of spraying in a controlled free cup effectively using this pre cup as a combustion chamber similar to a gas truck head that...

    Speaking of keeping it cool where would one find lower temperature thermostats for the dual T stat housing

    I'm trying to figure why our engines have bad harmonics that caused the crank to snap. Realistically our camshaft and firing order are the same as a race cam with the timing reconfigured for a sbc. The sbc guys swapped the 4 and 7 and 3 and 2 to reduce hot spots and improve power so why do we...
