I know from experience supercharger manufacturers will not release a kit that makes more power than will be reliable for a daily driver.
With that said, I expect the included calibration (Regarding the '04-'05 Mustang and F-150 kits) to be conservative (Pretty rich and not alot of timing advance). The latest EEC V systems have no service port (Require a reflash instead of a chip), use fly by wire, and are wired so tight that modifying them without code changes is dangerous. This is why tuning and larger injectors are included with the system, where an FMU and supplemental fuel pump are used on the earlier (Vehicle year model) systems.
Forgive a newbie his ignorance, I am just now starting to learn about this. The bottom line is I want a twni screw supercharger, for additional "pin me back in my seat".
I am looking for additional thoughts on KB vs Whipple.
I have already come to believe that twin screws (WITH AN INTERCOOLER) is the way to go for me, (as opposed to centrifugal, NOS, turbo, or Roots)
CONTEXT:
2007 (turned 1 month old, yesterday) Mustang GT-Premium Convertible
4.6l V8 (3-valve) with 5-speed, 3:55's in back.
It will be a daily driver, with rare trips to the local 1/8 mile strip.
MAIN GOAL is feeding my need for acceleration, and desire to embarrass some Vettes, Goats, and rice burners, at the occasional stop-light showdown, . . . but mostly to accelerate myself silly, till i feel like i need to pee.
LIMITS:
RELIABILITY is a key, with future expandibility being a lesser issue.
I don't see myself putting in a roll bar or cage in this car, and don't see myself doing other many other mods like cams/heads (other than some exhaust changes if needed)
(forged pistons, and rods, etc if needed would be ok if the blower/pulley choice calls for 'em).
I like KB's web site, and feel like I have learned a quite a bit from their FAQ's.
I had kinda decided on them, despite pwcracer's ordeal see this link.
Then, i was reading the Supercharger Slugfest Article from MM&FF's July 2006 issue (I back ordered it) and read about how there were no convenient replacement options for the belt other than directly from KB.
Then I started thinking: if I went with Whipple/FRP, then i could probably get it installed/serviced/warrantied by the dealership, and parts availability would probably be less of an issue, (though hopefully never needed).
This had leaned me more to whipple till i read the quote up at the top.
IS THIS TO SAY THAT FORD/FRP HAS 'DUMBED-DOWNN THE PROGRAMMING', thus limiting the potential gains.
If so, is the whipple any less ammenable to an "outside source" tune, (to reclaim and HP which may have been "dumbed-down') than would a KB?
If it weren't, would i even notice them?
