Unless there is a rule on injector size and boost level, the forced induction cars can potentially do a lot better than 50-100hp, not to mention the torque and rpm increases that come with doing the stocker tricks to them. That Cobra Jet is a pulley and calibration change away from 600hp at the wheels or more, and with motor work and exhaust that may hit 700+. It's a 9 second car, and unless GM and Chrysler come up with something that can compensate for the Ford's extra valve area, supercharger and rpm capability, they are going to get smoked.

That would be the same as making all carbed cars run the stock jets.

and boost level

A good start would be to police pulley sizes on super charged cars. On turbo charged cars the factory turbo has to be run. I kind of remember one Turbo Regal getting tossed for the wrong impeller a few years back. So, maybe they do check that stuff.

Alright, barring a rule book and a proper quote, let's go with the ability to run any injector. With just injectors, fuel pump upgrade and exhaust, and the calibration work, and a pulley change, that's 700hp at the wheels. The streetcars are doing that now. With a dedicated build and high rpm valvetrain, more compression (these days running 9 to 1, 10 to 1 static with boost is normal with a modern chamber) because of the blueprinting, and an agressive tune on race fuel (or E85 if it's allowed since I think the car stock is flex fuel capable, could be wrong) it could hit 1000hp. Even if the pullies are policed, the extra rpm from "stocker" style cams will more than make up for it. Going thru the traps at 8000 plus, that blower will probably pumping 20 or more pounds of boost. Low 9's, maybe 8 second quartermile? And here's the funny thing, I am a Ford guy and I feel conflicted about letting a car like this loose in a "stock" style class where the vast majority of the cars are naturally aspirated. The bottom ends are strong enough from the factory to support 1200 rwhp. Heck, Helion put a twin turbo kit that integrates into the blower system for the 4.6 Cobra and 5.4 GT500's and made something like 1000-1200hp at the wheels; and it's totally streetable. Civilized until you give it gas and the world goes completely backwards. This car in the right hands can totally dominate the class, which just messes up the racing. It won't be close. The new Challenger will not keep up unless it can spin to 10000 rpms and live, and have a huge weight break, Chevy the same thing.

THE CURE......Outlaw all supercharged and turbo charged engine combos OR have a seperate class/classes for them. Then its a dial in (Bracket racing). Problem cured !!!

I'll go with the seperate class, it's the only thing that makes sense. I don't understand why Ford was allowed to do this anyway, seeing that they are about to introduce a larger N/A modular motor. A proper Cobra Jet would have been to build on the new engine platform a 428ci engine with all the good stuff and been done with it.

Oh great!
Stick me with the 142 mph CJ's huh?

No not really. The new CJ's would be in AA blown fast class and yours could be in ZZ turbo slow class !

The only cure in my opinion is to follow OEM technical guidelines for boost pressure and NHRA follows it with mandatory pop-off valves calibrated and sealed by NHRA tech. If the OEM can't or won't provide the boost pressures, then they don't race. Turbo or SC engines should not be placed in a separate class as these are in fact what Detroit produces for todays market. But I also know that there is a range of acceptable boost pressures designed into these engines so they can be built to survive through warranty.
I know when I raced my '87 Shelby Z Daytona in A/FS there was an OEM boost standard for standard turbo-charged 2.2L Daytona's and another boost standard for the hi-po Shelby engine.
SCCA went to the SCCA provided calibrated & sealed pop-off valves back the early 90's when the Chrysler Turbo FWD cars began dominating the circuit. Once the boost levels were kept in bay, the dominance ceased.

Yeah. Can't wait to race them , having a 50 MPH deficit.
