[QUOTE="McRat, post: 13678310, member: 4984"] Yeah, I remember those days. Ford certainly does dyno test their production cars before badging them. I would have to say that like Mazda, they lied about the output. Here was the history. In 1997 GM came out with the LS1 SBC (347ci pushrod), and had badged the Z/28 at 305HP in '98 (SS's got 320HP badging). Ford's smaller 305HP DOHC was released in the 1999 Cobra with 320HP badging. So I'm trying to decide which one, and I'm leaning toward the Cobra. However, a visit to your local Test-n-Tune showed some WILD numbers. A hotshoe in a '99 Cobra was over 1/2 sec and 5 mph slower in the quarter. F-bodies with the LS1 were trapping 103mph with auto, and 107mph with manual. Cobras were about 99-100mph. Next, at your local dyno days, the F-Bodies were routinely hitting >300rwhp. OK, GM lied also (this has to do with the Corvette Brand Manager, but that's a different story). But the Cobra would often dyno out at ~255rwhp. No, a manual trans car doesn't lose 65HP through the drivetrain. Not even close. There really isn't much debate about 1999. This was very common knowledge by owners. [/QUOTE]
