yeah it is.
I've seen ones on Navy ships, but not that big or that good.

what engine has that?

Hence the reason I asked " Are you serious "
Pretty difficult to judge sarcasm on the internet buddy... I was trying to help, thinking you may not know. Have a nice day.
Peace

Care to share, I read that primer on a fairly regular basis. Kinda hoping one day some of it will stick. I'd like to know what you disagree with, for comparison reasons that is.
Since the stock fuel system can be pushed to 275rwhp, you definitely don't need or want bigger injectors or pumps before then.
You do not need to get rid of the AFM, the TVIS, the EGR or upgrade your stock cams, or port your head, or get a larger throttle body, or an aftermarket intake manifold, or get forged pistons or anything like that until you go over 275rwhp (and way beyond that for some of these things). Don't waste your money on these.
The power primer does suggest using an AFPR+SAFC to get you through the 230-275rwhp range and it will work although your strategy will have to change as you get to 250rwhp and you find that you cannot richen the fuel any more. One is the AFM signal, but the other is that the 440cc injectors reach their limit around there at lower fuel pressures. At that point you must turn the fuel pressure up a little bit more and you will find that the system will richen up to were it needs to be under full WOT again. As you do so, you get into the range where the S-AFC only needs to be applied on less than full throttle boost but that the limits of the fuel system by themselves are enough to give you a good AFR at 100% throttle. If you or your tuner then really know what you are doing you can continue to apply the same tricks to get you up on larger injectors and progress beyond the stock fuel injector limits. How high you can go just depends on how high you want to go and how good you or your tuner are at finding the proper balance, although after the AFM flap is completely open you start to lose your ability to keep a good AFR both at full WOT and part throttle boost. If you are really motivated, you can break through the barriers. You could even rig up two AFMs and two stock ECUs and fuel systems to effectively double the potential limit of the system (I think I'm going to regret mentioning this hack).
I find all this discussion about how you can balance fuel, timing and airflow issues near and above the limits of the stock fuel system with FPR and black boxes somewhat tedious. The potential gotchas there are many, and they all bite hard. Given the high inherent risks, the smartest and most capable tuners are going to go where the money is better and the power rewards easier to pick. Even if you navigate through the obstacles safely you will probably find somewhere between 300-400rwhp that you have invested enough money, time and expertise getting there to pretty much have been enough to buy and tune an EMS.

Here is the new link.The cylinder bore is just under 38" and the stroke is just over 98".
