I don't think there are speed limiters on the Z-rated 4th gen F-Bodies, but there are rev limiters, and rev limiters will keep you from going faster when you reach the upper limit of RPMs.

As for the Aero argument, yes it's impossible to eyeball Cd. But assumimg similar shapes will yield similar Cd results is reasonable given that both shapes operate in the same flow regime.
A comparison of Frontal Area, length, and surfaces (likely to trip the boundary layer, i.e. grille dimensions) will show that the Camaro and Mustang have ALOT in common. Expecting similar #s for the two isn't a stretch by any means. I still can't find an 05+ Mustang's Cd anywhere.
Oh yeah and I too have that Anderson book.

If you've ever looked at the OBDII you'd know they have rev limit (by gear) and max speed limit.
LS1 cars were factory set at 6200 rpms with a max speed of 160mph (might have been 162, I'll have to go look again.)

Fascinating thread!
I have but one point to add in reference to the third gen's aerodynamics. I remember that the third gen firebird has been the darling of the Bonneville top speed crowd for a long time due to its aerodynamics at speed. I seem to remember a record being set in one.

It is a true statement though, the dimples also keep make the ball much more accurate...as long as I'm not swinging the club.

Yet another reason to model it after the Ferrari 612 and go with a strong 2nd/third gen influence. Splash in some Corvette blood, and you have yourself a fantastic looking Camaro.

The 612 looks like cross between a Miami Vice Ferrari, a 4th gen with 50's Vette Door C indents anyway.

I don't think there are speed limiters on the Z-rated 4th gen F-Bodies, but there are rev limiters, and rev limiters will keep you from going faster when you reach the upper limit of RPMs. For instance top speed on 6-speed cars is attained in 5th gear, and the top speed point is the point of which the rev limiter kicks in and safeguards the engine from destruction. LS1 have a much higher rev limiter than the ole LT1. Rev limits can be changed with a programmer. The talk of a 162 mph limter on stock LS1s is probably the rev limiter in 5th gear.
Speed limiters are set at a certain speed, usually the speed rating of the factory tires. My old Caprice LT1 had a speed limiter set at 108 mph, and didn't take long to hit it if you kicked down on it on the interstate. After I reprogrammed it I ran into another problem at WOT the transmission would not shift out of 3rd gear so it would hit the rev limiter at 128-129 mph. To go faster I would have to let off half way let it shift into 4th then get back on the gas.
You can really tell/feel the difference in a speed limiter vs.rev limiter. A speed limiter when you reach that terminal speed kills the gas for several seconds, until the car has slowed by at least 5 mph then resumes gas.
A rev limiter when hit is very fast off and on again with the gas. Some of you may have heard people hit the rev limiter at the drag strip doing burn outs, the same goes for top speed runs if you get the RPMs high enough.
