2007 Mustang V6?
 

If I read the stock car classification correctly, this should fit O - P/SA. however the question I have is under the classification is reads ESI (Engine specs Incomplete, but it gives a HP rating of 210 and a weight of 3345 for the rag top. Is this a legal combination to race with or is it not allowed due to the ESI designation?

Re: 2007 Mustang V6?
 

You would need to contact the Tech Dept. and get someone to put the engine specs in the guide. Until that happens, the combo isn't approved.

Umm, I was corrected about the way to get your combo put in the guide. You would have to contact someone from FFFord and ask them to submit the specs to the Tech Dept..

Re: 2007 Mustang V6?
 

Yes, you have to contact somebody at Ford that will send in the info to the tech dept. When I got the 2003 Mustang stuff put in the guide, Jesse Kershaw was the contact at Ford racing and he was a great help. I would try to contact Ford racing.

I'm a little lost here.
I need more details regarding that post.
Since this car is in the official NHRA Stock Car Classification Guide, rules says: "Only those cars listed in the guide are "eligible" for competition". This car is in the guide, so it become OK. There nothing in the rulebook regarding ESI. (May be I mist something here?)
Now if I go to the Blueprinting paragraph:
Stock factory OEM components (unless otherwise specified)must be retained and remain unaltered.
This tell me that when ESI are not available from Ford or NHRA, you must keep OEM components.
Thank you in advance for your precious help,

There are lots of combinations in the Class Guide that are like that. If there are no engine specs, then you cannot race it in Stock or normal SS classes. You can use it to build a SS/GT car or an SS/Modified car. Usually that is why the combination is there.

Re: 2007 Mustang V6?
 

Thanks Mr. Southerland,
I was aware of that (*) regarding SS/GT and SS modified. Your answer also confirmed me, that NHRA Rulebook isn't complete in that regard.
An add-up, like you said, (If there are no engine specs, then you cannot race it in Stock) should follow the text: "Only those cars listed in the guide are "eligible" for competition".
(*) By the way, your website Classracerinfo is a fantastic tool.
Keep on Sir,

Thank you for the appreciative remarks!

There is a statement in the rule book that can be taken as an explanation, though it does not specifically explain the ESI issue.
"The power-to-weight factor (as found in the Official NHRA Stock Car Classification Guide) determines the natural class for all cars."
If there is no power-to-weight factor, there is no class implied.

Re: 2007 Mustang V6?
 

Thank you, that is what I was afraid of. Will just keep looking for now.

Re: 2007 Mustang V6?
 

I was thinking about this combination too a while back. When I was at the PRI show I intended to talk to whoever is in charge of the drag racing program now but I never had the chance to. Does anyone know who it is now and maybe his/ or her email address?
It would be a great starter car for someone just getting started.

Re: 2007 Mustang V6?
 

Mr. Southerland, your point of view is interesting for this discussion, and, I must also add, in the CLASS WEIGHT BREAKS section, the sentence (based on pounds per NHRA-factored horsepower) under this tittle, can also be taken as a part of the answer, though it doesn’t also explain the ESI specs situation.
But further in this same section, a part of it, said: The power to weight factor is the shipping weight of the vehicle divided by the advertised or when applicable, the factored horsepower for the OEM assembly line cylinder heads.I’m still questioning the meaning and also words like: “advertised” and part of sentence like “or when applicable” to explain my understanding of the rules.
Sorry for “this too long post and THANKS once again for this very good discussion and your precious help. I’m still learning…
Keep on Sir,

Please note my statement "There is a statement in the rule book that can be taken as an explanation, though it does not specifically explain the ESI issue." I was not trying to defend what and how NHRA's technical information is assembled or has been published. But, in practice, if there is not a power-to-weight factor listed, you cannot classify the combination in Stock or traditional SS.

There was a practice put in place after the SS/GT classes were defined that allowed manufacturers to submit shipping weight information about models they wanted to be available for competitors. This was more common in the late 1980s and 1990s than now. Manufacturers used to submit a lot more of their product line than they do now. Some manufacturers transitioned to primarily FWD cars and mostly 4-cyl and 6-cyl products but still wanted their name and make to be showcased, so the information was submitted for their cars to be eligible for those classes, but the engine data was insignificant. The manufacturers target was the SS/GT classes and other modified classes specifically and shipping weight is all that was needed. It would be good for NHRA tech department to include some statement in the rule book or accompanying the technical documents that provided a simple explanation for some of those "unwritten" processes and procedures. Not everyone has be privy to historical moves and decisions.

There are 223 engines referenced in the Tech Bulletins-Class Guides with no engine specifications. Most are listed as "ESI" (Engine Specifications Incomplete) or "NES" (No Engine Specifications). Some are shown in the Class Guide but have no corresponding information in the Technical Bulletin for that manufacturer (ex. 1960 Ford 312-205hp in the Mercury which has power-to-weight factors but no engine specs). Maybe it would be nice for the manufacturers to provide that information, though I doubt there would be many that would become race cars (like about 90+% of the combinations currently in the books!). In my opinion, I wish the "less than performance engines" of the current muscle car era were in the books because the sport cannot maintain on 40+year old combinations.

Re: 2007 Mustang V6?
 

Thanks Mr. Southerland for sharing this statement and all those new interesting details to me.
That’s clarified my knowledge (my vision) of this portion of the Stock class rules.
This will certainly help to avoid costly mistakes.
I also agree: NHRA rulebook need some refresh in that regard.
And a BIG + for your patience,
Keep on Sir,
