I don't see any discussion on the Holley system for the 5.4L. Anyone have experience with it?

 

I don't think anyone here, that I know of, has gone that route. Pretty pricey kit!

 

Before the Supercharger Forum was opened there was a guy who put a Holley kit on his Super Duty. Search all forums for "Holley Supercharger". As I recall, it was a PITA to get installed because some of the parts didn't fit and the kit wasn't very complete but he was very happy with the final results.

I have a Holley S/C with Jet Coated JBA Headers on my 00 HD Ford. Since this was a fairly new setup, there were some minor problems (installation wise), which I understand have now been eliminated. I don't know for sure the HP increase, since I have not had it on the Dyno, but have over 5000 miles on it and no problems. I don't try the stop light much anymore, but have occasionally taken some of the "hotter" trucks and cars. Overall, I feel it is an excellent product.
