[QUOTE="mustangc, post: 10158462, member: 87570"] I'm confused. I thought the upgraded pumps were a standard feature of the 2.9L Whipple kit from Whipple and from Ford Racing. I guess Lethel must must buy the tuner kit (just the blower) and add their own supporting components. That just goes to show you that the Ford Racing engineers must know what they are doing when they build their kits, huh? Too bad the aftermarket tuner shops don't learn from Ford's hard work. In Lethal's defense, the FRPP kit is rated at 17psi. Is it possible that Lethal's kit has a slightly larger blower pulley to lower the boost to the 15 psi you are seeing, and that small change allows it to just stay within the capacity of the stock pumps? If that's the case, do they sell their kit for less than FRPP? I can't think of any other reason why anyone would purchase an inferior group of parts than what comes straight from Ford...:shrug: [/QUOTE]
