Re: HP Adjustments on NHRA.com
 

Man, there's a lot to digest since I posted.

First, you young'uns need to look up (or ask somebody that was there) the history of the GT cars and for that matter, the FWD conversions. In all likelihood, you wouldn't have a place to race now had that not happened.
Yea, I know you may think I'm making this up. Check it.

Now, this inherent (I read it , huge) advantage the FWD cars have.
Well....better ask the AH guys. Don't hear them whining. Have stock control arms, stock K-member, stock steering box and steering and, yes, 45 year old (unaerodynamic) bodies.
Doesn't appear to slow them down (@160+ mph). Who ever dreamed they could go this fast? Not me.
So what is the difference? For the most part, these cars are state-of-the-art chassis in old bodies. Aerodynamics??? Doesn't appear to matter, in my opinion.
The trouble is, there have been few, if any 45 year old "new" Super Stock cars built with today's technology. Big difference! (yes, there are some stockers built with success).
**PM me if you want to know more as I have an example.

Food for thought......
Anybody remember John Lingenfelter's A/ED and it's success? (yea, I know I'm old and that was comp).
Ask someone or look it up as it could easily pertain here.
"Be careful what you wish for" , the same thing could happen again.

Now go work on your stuff, guys.

I could care less because as I'm one of the people that needs to go work on my s$$t. I will say this if you think a Cavalier,Cobalt,G5 etc doesn't have a advantage aero wise over say a piece of plywood like a Chevy II then I have some ocean front property for sale in West Texas lol.

Drag coefficient isn't the whole story, a fourth gen camaro has a drag coefficient of .34 and a new massive Dodge Durango is .33. You have to multiply drag coefficient by the frontal area to get the real numbers. Here are some numbers I found searching online (may not be 100% accurate, couldn't find a database with all of them).

1988 Camaro IROC Z-> Cd = 0.34, A = 21.00 ft^2, CdA = 7.14 ft^2
1988 Firebird Trans Am-> Cd = 0.31, A = 20.75, CdA = 6.43
1993-2002 Camaro-> Cd = 0.34, A = 22.00, CdA = 7.48
1993-2002 Firebird-> Cd = 0.34, A = 22.00, CdA = 7.48
1995-2005 Cavalier-> Cd = 0.38, A = 20.2, CdA = 7.24
1997 Sunfire-> Cd = 0.38, A = 22.2, CdA = 7.68
2005 Cobalt-> Cd = 0.324, A = 23.1, CdA = 6.90
2005 Stratus-> Cd = 0.33, A = 23.1, CdA = 7.03
C6 Corvette -> Cd = 0.286, A = 22.3, Cd = 6.38
C5 Corvette-> Cd = 0.29, A = 21.3, CdA = 6.18
2008-11 Challenger-> Cd = 0.35, A =25.3, CdA = 8.86

FJ, sorry but AH cars are no where near the stock chassis that came from the factory. I have heard the steering is moved as well. Then there is the motor. MANY MANY variations from what was allowed in SS 10 years ago. Those motors would make a FWD run better too. Reason they don't complain is they are ALL one Chassis. All one motor. All same motor rules..... An expensive Mod class just called SS. Again fake HP ratings but it doesn't matter since they can ALL do the same stuff to the same parts...
If all 69 Camaros with 350 PG you would still hear NO COMPLAINTS.. Use the factoring system and the any chassis deal and havoc results.

Try running a G body!!!
I've been writing letters way before fwd conversions.

Seems I got left off the "gift list for the 390 Ford".

A few years ago somebody knocked off 50-75 HP off some Corvette, then the 400 Chevy got a typo, then the 390 Fords got a gift, and the 383's (both stones), I'm sure there are other examples as well

I'm at a loss......

Fixed it for you Dick. After the last Hemi debacle I realized that even when I do complain, no one listens anyway!!!

Carry on, Labor days coming- I've got a lot of work to do....
