    Even with hpfp upgrades the fuel volume these pumps can make isnt enough for the massive amount of fuel required by the ecoboost.

    Some problem gm is having with there DI only stuff.

    Speculation is a cam with a different high pressure fuel pump lobe is needed to pump the DI pump up more at low rpm.
    I'm curious to know the results of fuel lobe only, hpfp only, and both combined. I need to re-read the HPFP results, pretty sure I've seen it around here before but I can't recall the numbers off the top of my head. You're saying there is still a pressure dip at lower rpm?
    Also I believe I've seen mention of cam lobe providing 50% more fuel, plus the 35% pump. Combined these could provide double the fuel flow of stock overall?


    Just thinking... if we are limited by cams and air to around 550-600, how much fuel does that take? So even if we had 4 HPFPs as some have proposed, you'd still be air limited at 600? And still need new cam profile to use all that fuel.

    I recall reading the same things. GT is still a smaller wheel right, so should spin more easily with less flow? So how much difference does that make(rpm), just out of curiosity.

    Seems like if you're doing cams though, you wouldn't mess with GTs anymore at all. Why sacrifice so much top end for just a few hundred rpm down low? Especially considering the useable rev range and shift points, as Mr. Matt and others have mentioned.

    I know that I'm paying close attention to these 2018 turbos, looks like they're beastly for sure once tuned up.

    I'm going off of memory here, but I believe I'm around +50% fuel over stock. 35% from HPFP and 15% from the HPFP Cam.

    In testing with this set up, even on the higher demand pull, I never fall below 2000psi at the rail (commanding 2200) and that's for a very limited time. With the stock set up and commanding less boost off the hit, I saw drops as low as 1100psi. So I'm pretty impressed with the cam and pump.

    We'll see what limitaions the cams present, but I still think I'll run out of injector or start knocking (due to our gas) before the cams limit.

    You're a stud, Benny! You also upgraded the in-tank right? How much is the returnless set up and in-tank helping with that 50%? Forgot about injectors... when do those run out? I don't think I'll have that issue with GTs, could be an important detail if looking into the 2018 snails. Although it looks like GH is making it work to 510+ and might have another 20 to go. Pretty crazy to me to get 500+ to the wheels with very minimal work

    My mind is so scattered trying to recall all this stuff I've read. I'm too busy and shouldn't even be on here lol, sneak in for a quick mental break and am distracted and forced to think.

    You can still use the GT upgrade cant you? And gen 2 should be able to use the 18+ turbos that are better according to fullrace and RMB stated on here. The H.O. engine (raptor, navigator, 19 f150) also apparently have stainless (dont know grade) manifolds which can handle heat better i imagine.

    why the lol? there is a few of us making 550whp on good ethanol tunes. but that is pushing the turbos past its limits to achieve that. which is why its a race calibration only not ran often and only in good air.. matter of fact had great luck so far. over 60 data logs. probably 50 booted launches with my 17 fx4 with almost all being sub 4.0s 0-60, so far so good for me. *knocking on wood* good fuel, good air, good calibration and a good set of eyes to monitor the right parameters is key

    It depends what love profile as to how much more fuel it will produce but stock pumps cannot handle the lobes we use.

    There are a few things we will show soon. But we have no issues with fuel on the one lobe or issues with fuel running out flowing 100 plus lb/min. Some cool things happening right now, it will make for some really informative info.

    I’m curious how the ATI balancers we carry and use compare to a new one we are working on and plan to test.

    You might take a couple of hours off sometime soon and set it aside to SIT DOWN, relax at a desk, and BLOG for a bit. Just download some of that stuff in your head and let us know what's up currently. And yea, maybe a little info on what's coming too.

    Has anyone actually degreed the cams? Gen 1 & 2.

    ...and posted the results.

    ...also might find some data in the FSM.
