Yep. The track was cold as well. Gotta throw those out.

I personally ran 11.19 and 13.98 on the same night! Wish I could blame it on the track - it was all driver error - and traction control in the ON position. Car fell FLAT on ts face off the line. I looked like a TOTAL SQUID! LOL!

is it at all possible the 662hp rating is at the designated "redline" and the "overrev" rpm range isnt part of the sae certification since its technically limited?? sources please.

The "overrev" doesn't come into play in the certification at all. The engine is certified on an engine dyno. It makes what it makes. As long as the engine can operate at that engine speed in-vehicle, the manufacture can advertise it. In the case of the GT500, it makes peak power at 6500 RPM. The fact that it can run at, and be shifted beyond, that point makes the advertising legitimate.

NOTE: When I say it doesn't come into play at all, what I mean is it doesn't limit what can be advertised. It obviously comes into play in allowing the vehicle to operate at and above the engines peak power point.

Don't forget dusty too...

since youre so versed in sae ratings, what do they (sae certifiers) say about the overrev feature on the GT500? and how does that affect the ratings?? links?

Well, if Automobile magazine has it right, the 662hp rating is WITH the over rev feature. From the article:

"Seven grand from a huge stroker of an V-8 means piston speeds approaching those of a NASCAR engine, so all of the rotating masses are forged for lightness. And strength: at maximum load, the supercharger takes some 150 hp to run, so the engine block is actually supporting more than 800 horsepower. The high revs and enormous power output come with a corresponding buildup of heat, and for that reason the GT500's engine can be revved past 6250 rpm for only eight seconds at a time. Each second spent over 6250 rpm must be redeemed with a second under 6000. If the full eight seconds are used up, the engine computer will lock out the overrev function until the engine has been under six grand for fifteen seconds and has ventured once under 5000 rpm.
Since the 662-hp rating occurs within this overrev band, you can technically have all 662 hp only for eight seconds at time. That would be a problem except that the only gear in which you'd be able to exceed 6250 rpm for more than eight seconds would be fourth while going uphill -- as you approach the shift point into fifth at 173 mph. The GT500's top speed is reached in fifth just below the 6250-rpm limit. In other words, the eight-second limit is irrelevant."

cool, i see. Well hp at the wheels is way more important than flywheel since thats what the tires see. 600rwhp+ is an awesome number

huge stroker of a v8??? wow they sure know how to embellish things over there. Its only a 5.8L engine. even the 7.0 LS7 is only barely mid sized by todays stroker engine standards.

Nice to have choices...and we now have several...

True actually. Might explain the pull the Caddy Coupe has on me.

Funny. I've actually owned a bunch of Les Paul's. Great sounding but I always end up selling em for something else. Still have an '03 R9 though. Les Paul's are like Camaros. Look great, perform well but are too heavy. LOL.

[2ndCamaro79]

Just to lighten things up

[2ndCamaro79]

Neat piece on Shelby and the GT500
