Factory experimental

[Yo Ken]

Jeff,

Before you make a post about the moderators of this forum, please contact us first. In the past I overlooked your remarks about Class Racer and the way it is run. I feel I have been more then fair with you, and instead of emailing us about a missing thread and thinking you are getting singled out having your posts removed, you post it here. An email would be nice next time.

I do not want to hijack this thread, because I feel it is an important one. I think the next time you post a thread you need to stay on topic.

The thread about the CJ's was accidentally deleted when a member made a post that had nothing to do with the thread. I'm the one who deleted it. It had nothing to do with you. Now that I took this thread where it should not have gone, are you satisfied?

Rory..The Fi cars got there own class because the everyone was uncertain how it would turn out and were brought back in after many years and the classifications seemed to work within reason..maybe the same should be done this time around...but i still think they should be SS cars..because thats what they are!!!

p.s. I dont see how they could pssible stay in stock if they will get the hp the way it seem they probaly should..or will NHRA fast add AAA and AAAA?

what makes these new cars super stockers?

Power to weight ratio...probably.."in real life"

The 2008 Cobra Jet is in the NHRA Stock Car Classification Guide. The shipping weight for the coupe is 3239 (7.62 X 425) and the convertible is 3324 (7.82 X 425).

The actual shipping weights for the Mustangs are much higher than the gifts from nhra.

Let's use the Ford Executives figure of 720 Horsepower and nhra's weight of 3,250 pounds to check the trusty old Moroso Calculator. These things are usually pretty close.

Edit:
Add 170 for the driver = minimum weight of 3,358.

Answer: 9.51 @ 141+ MPH. Yes, they would have to get the car to stick.

Where were you guys about 6 months ago, when I was beating the drum for tell-tale boost gauges on all forced induction cars because of their inordinate showing as #1 qualifiers at National events??? In the last four years, (had stats for 2004-2007 at the time) about two percent of the cars (turbo cars) had nailed down something like fifteen-percent of the #1 qualifying slots... a statistical anomaly that screams for attention.

Now that the issue is a different one, but the cause of the problem is the same, you come out with this.

Since horsepower at the flywheel is almost certainly boost-dependent, OF COURSE it needs to be monitored to factory specs, one way or another. Tell-tale boost gauges is one effective way to do it.

I still think these "new" factory race cars belong in S/S.... especially, the ones with less than 7.5 lbs/hp.

My 2-cents...

George,
Thanks for looking up the numbers.
So if a 425 horse mustang goes 1.4 under it will get 3.25% Monday morning that will put it up to 440 horsepower. With only a 3239 shipping weight the hard top would end up at 3239/440= 7.36 and would no longer fit in AA it would be a natural SS/C the car is only 7 horsepower away from not fitting in stock. The convertible has a little more leeway but not much. I could see an AAA class coming awful fast!

[Bruce Noland]

An excellent 427 will make about 640 Horsepower tops.

[Bill Edgeworth]

It will be real interesting to see how this all plays out. First off how can they possibly fit in stock with AA having a 7.5 P/W factor a 500 horse deal has to weigh 3750. Add 100 hp and it’s got a minimum of 4500 pounds. I don’t know what the shipping weight of a mustang is but its sure not 4500 pounds. Anything over lets say 550 hp is going to put them way under the AA 7.5 minimum. So will we see 5000 pound mustangs or an AAA class? I would say that the AHFS would eventually catch up with them but it’s a interesting situation when if they make a 1.4 under run they will have to add something like 140# all at once. Where I would be real concerned if I was an A or AA racer is if these cars end up getting the index’s hit. Another point to ponder is that to use the Hemi Darts and Cudas as an example they were never able to run in stock due to their P/W ratio. They only fit in Super Stock. Isn’t this the case here?
