5.4 Triton Power Upgrades

What are you guys using for reliable power enhancements on this engine?

My current performance mods include K&N Intake w/ heatshield, flowmaster 40 series, and 75mm intake (soon to include the throttle body elbow being ported).

Those dont equal much at all I'm sure in the HP department, but they scored big in my SMILE department! I'll go the way of tuner/chip next, and when I'm making the big bucks next year... supercharging/N02

If you have a 24v 5.4 check out the Whipple supercharger, it is a lot of money but has awesome power. They offered it for the 16v for a short time then quit.

do your homework.....We installed a whipple on the bosses Escalade. It was good for one pass and then the blower heated up the intake air so much that the ecu pulled all of the timing and the motor had less power than it had when it was n/a. The Whipple is not intercooled and that is not good. Look at all of the available ones out there, even Ford has one I have seen in Summit Racing. Good Luck.

Me and a buddy did it over a weekend (two full days).
We took our time.

IMHO the best & most reliable install will be the Procharger kit...plus larger fuel injectors/fuel pump/custom tune (not part of the kit).

The Procharger kit comes with an FMU to increase fuel to the engine, but this is not incredibly reliable/accurate.

You'll make more power, and have better control of your air/fuel ratios, byt installing larger fuel injectors/fuel pump/custom tune.

But lots of guys are using just the Procharger kit with good results.

how much was your kit? trying to decide between a lightning swap and just a procharger as stated in your post above. also, i literally just had new spark plugs installed. will i have to swap them out for colder ones?

Hello everyone, new here because I just sold my 02' lightning and bought a 2000 5.4 4X4 expy-really like it so far.
Anyway, I used to work for ATI procharger and for what RPM the 5.4 motors like, the roots/screw blower will be much more practical. Also, the Expedition kit uses (4) small idler pulleys which tend to burn up often. Other problems are the P-1SC model superchargers all leak. The procharger will give great "peak" power figures but low end torque will not change much. The eaton is without a doubt the more reliable, usable blower.

The eaton blower would be my choice, but be careful. The harley/lightning motors have forged pistons. I'm not saying the expy 5.4 can't handle 8-10psi, just not as long as the lightning... Premium fuel and octane booster is recomended, and watch those spark plugs!

Sorry, I was referring to the eaton vs. procharger(discussed earlier) and I wouldn't run anything colder than the stock lightning plug or you'll run into some fouling. The 5.4's of some years were known to eject sp plugs and adding a blower certainly won't help prevent that problem! Prof. tuning would also be recomended.

i plan on having it tuned by the tuner who tuned my xcal II. so, no real big difference between the harley vs lightning...just whichever has a better deal?
