Who's the Baddest B/SA now?

The drag created by any car body in motion, is proportional to the square of velocity, so it is important at any speed. The force will increase as the speed increases.

Drag starts to have a noticeable effect at 10 MPH and downforce, depending on the frontal shape of the car, as early as 40 MPH.
This is not taking into consideration the rake of the body as it accelerates down the track.

Like the adage says, looks can be deceiving. Although a car may look or appear to be fast just by its looks, it does not mean it is aerodynamically efficient.

The 1998 thru 2002 Camaro are one of the most aerodynamic cars ever built. Below are the body specs:

Wheelbase

101.1

Track Width (Front)

60.7

Track Width (Rear)

60.6

Length

193.5

Width

74.1

Height

51.2

Ground clearance

4.5

Cd

.34

Below are the body specs for the Corvette:

Wheelbase

104.6

Track Width (Front)

61.9

Track Width (Rear)

62

Length

179.8

Width

73.6

Height

47.7

Ground clearance

4.0

Cd

.32

The Camaro has a shorter wheelbase and narrower body than the Corvette.

The Corvette has a lower roof height and shorter length than the Camaro.

The difference in both cars drag coefficient is only .02 which in the case of a drag car, is technically irrelevant.

So in a nutshell, the Corvette does not have an advantage over the Camaro as regards to body size or aerodynamics.

As a matter of fact, I believe that more detailed analysis will show the longer body and rear shape of the Camaro is an advantage at higher speeds and weight transfer when compared to the blunt, short rear of the Corvette.

I'm surprised talk on this is continuing. J Allen can bomb the B/SA index anytime he wants. But that would be stupid. I've seen a video of the red vette testing at B weight and all I will say is you boys better find some more............

Ed nailed it!

It's talked about because that's what we do and it's fun. Allen's car is wicked bad fast. But anything can happen at anytime. He didn't run B at Indy last year l, Slate Cummins did and lost to Jim Boudreau. I sure Kevin Hems needs to be mentioned in the same conversation as Allen. That Challenger is very fast as well.

To me the king is crowned at Indy. Done.

Are there any Fords in the mix?

The Corvette is significantly better aerodynamically as the frontal area on the Corvette is much smaller. Here's some info that I found a while back for 4th gen Camaro/Firebirds/C5 Corvettes:

1993-2002 Camaro/Firebird: Cd = 0.34, A = 22.0, CdA = 7.48
C5 Corvette: Cd = 0.29, A = 21.3, CdA = 6.18 (note the Z06 is higher)

A C5 is actually better than a Cobalt, and a third gen is actually better than a 4th gen. Obviously this is at stock ride height with stock wheels/tires, etc, so it would change some for a drag car. That being said, if you do the math, it's only a few hundredths difference.

And this is the reason for my post! These engines in all combos SHOULD be rated the same! Even in the GTO's! At say 130 mph on the big end at best should only be a couple hundreds between them! Andrew can you find any info on say your combo and the 1st gen Camaro and the 70 Corvette to compare the drag coefficient to these cars discussed here?

Being an LS1 follower for years, you can stop smiling any time now Albert Lee, I believe the 346 LS1 in a Corvette is at factory horsepower of 345. If I remember correctly the flat hood cars were @ 305 hp and the fresh air cars were @ 320 hp. I could be wrong, but I always try to pay attention.

In all candor, if either car is that quick - or any for that matter, it sounds like the system developed to look after unbalanced performance levels such as this should be allowed to work. Why have the AHFS in place at all? If the system is valid and effective, let it work.

The AHFS would work a lot better if they used the 1/8 mile times.
