The Shelby name on this car is only badging.
The Shelby name is a car company name. You can buy a Shelby through your Shelby "authorized" Ford dealer but it is still a Shelby. The vehicles that Shelby produces start with Ford platforms and Ford drivetrain but in the end they are Shelby's. That's why 1967 GT500's can race with non-existant (at the time) single 4bbl's et al, because Shelby (not Ford) signed the required NHRA documentation.
Today and for the last several years, Ford Motor Company has only produced for public roadways a Mustang with either a 4.6L V-8 and a V-6.

And while I want to see my product successful it needs to as evenly matched as possible to the more established combinations. Since there is no way to know the absolute performance potential of any factory produced engine prior to someone spending the time and money to build it and put it through its paces. So the options are to either change the name of the current category to Nostalgia Super Stock and do not allow any new combinations or try to constructively support NHRA in keeping the playing field as level as possible.
now that the cat is out of the bag, what is the HP potential or airflow potential of that blower? answer the question honestly, or any further input to this thread will be meritless. I know what other blowers of similar displacement are capable of, even on the 4.6 4v motors. NHRA has admitted that they have no specifications on this blower (rotor specs, case clearances, pulley sizes, boost@the rated 425 hp, max boost and or airflow of the unit, etc). All of this info will determine the potential of that combo.

I once spoke with a very well regarded engine builder who specialized in turbo motors. I asked him what the ideal comb was for xx turbo. His repsonse was that it doesn't really matter, the turbo makes the power. I think that holds alot of merit with supercharged motors as well ( i understand that the positive diplacement blowers are somewhat more affected by upstream restrictions.

That would only be fair if your willing to have YOUR combo adjusted also. The combos you talk about are making at least twice the HP than is in the guide. Do you want them adjusted also? What your asking is never going to happen anyway. And the comment about not having a dog in the fight doesn't hold water unless your debuting a new car.
well based on that bolded statement, kiss your credibility goodbye.

do you really think a stocker L88 maks 880 hp?, a 425/427 makes 850? the SS versions of those motors don't make that

I asked all of the ford guys in pomona this weekend what they thought the capabilities of the car were with the blower, and none of them would give me a straight answer. They all know this thing has the ability to way go faster than 1.3 under, but not one would admit it.

Then i had the fortune of meeting one of the most prominent comp and super stock engine builders in the country, who was actually HONEST with me. I'm not sure if he would appreciate being named so i won't do that. But he explained to me that he going to be doing a motor on one of the CJ's and the he believed this combo is capable of 9.30s or 9.40s maxed out. It is definitely safe to say that the blower supports over 700hp, since they have a production motor rated at 700. I just really doubt the 700hp Shelby is the upper limit of that blower.

If they don't create a new class they will just baby these cars and absolutely destroy ANYONE who they have a heads up against. I want to see them stay, but it's pretty ridiculous how underrated they are.

Every time that they end up racing these things heads up for class, someone is going to want to win and then they will start getting horsepower. Eventually, they will have a trunk full of lead or NHRA will create a new class for them. Either way, they are kind of cool to me.

Not so at all. There is a Shelby GT which is a regular Mustang sent to Shelby's facility across the street from the parking area at LVMS for cosmetic add-ons. The GT500 comes out of Detroit that way.

No Chad I don't think those combos make that much HP. Yes, the car is underfactored, but you can't say put this combo on a dyno and adjust the HP but don't worry about all the other combos in the guide. I think you guys are blowing this out of proportion. I don't think there will be that many people running them. Who would want to work on one, much less tear it down at the track? There has been a supercharged Mustang in the guide for years and nobody has run one (that I have seen).

Does anyone know how many people are planning on running this combo?

Jeff there are two types of Shelby vehicles. Ones that were built as standard Fords (and previously Dodges) then delivered to Shelby Automobiles where they were modifed (ie: the original 67 GT500's, GLHS omni's and Chargers, etc), then there are the OEM built cars that carry only the Shelby name - Regular Shelby Chargers, Shelby Z Daytona's and the current GT500 Mustang. Shelby Automobiles does offer their own versions of the Mustang but they don't touch the GT500.
