I'm not sure exactly how much of the 550cc injectors you'd "use" to reach 400whp but I was getting occasional fuel cut at 11-12psi on the stock 440's so you'd certainly need to upgrade. As to whether 550 would be more than enough or just enough I don't really know but cre will  |
Thanks for the vote of confidence.... IRL, I'm actually a complete idiot.
Yes, you can get 400RWHP out of 550's. I think the following should get you there... You'd skip the Lex AFM. You'll need a good fuel controller and possibly an FCD. You do not have to eliminate fuel cut entirely with most FCDs. I don't usually recommend them as if you screw up you could melt a hole through a piston or burn valves when you really push it. 550's are enough though, you're not really asking a whole lot more than you can get out of the 550/Lex combo under ideal conditions (which is as much as 350 and in a couple rare cases a tiny bit over). An adjustable fuel pressure regulator, upgraded CT-26 and better intercooler would REALLY help.
