[QUOTE="Driver72, post: 9964275, member: 105832"] I'm gonna be the the first to say that I think the power rating of the 7 psi kit is under-rated by a bunch. If 9 psi produces 624 hp, how could only 2 psi less produce only 525 hp? There is no way 2 psi more boost gives 100 hp more, unless there is several other things involved with the 9 psi kit. However, I don't see much of anything different. Further, Whipple themselves, Vortech, and Procharger all make 7 psi kits for the 5.0 and all claim around 600 hp. To me that sounds more like it. I'd think if 9 psi makes 624 hp, 7 psi should be in the 580-600 hp range. I have a feeling once the FRPP kits are put on and people start dynoing these things we will see that they do in fact make more than 525 crank hp. You don't add 7 psi boost and gain 110 hp over stock, but then add 2 more psi and gain another 100. Ford most likely did this for one reason: GT350 The 7 psi kit is probably the same as they put on the GT350, and we all know they could not advertise the GT350 as having more power than the GT500. So to "protect" the GT500 and it's power, did Ford intentionally underrate the GT350 (and therefore the FRPP 7 psi kit)?? We shall see soon enough, but I think it's very probable. And if that's the case, and it really does make closer to, say 580 hp. I'll take 580 hp and a 1 year warranty over 624 and no warranty please! [/QUOTE]
