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).

[Bruce Noland]

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...

Rory, Yes there were supercharged Ford's and Studebaker's in "Stock" many years ago. Larry Walker and myself at one time had to make a full pass, with a tech inspector riding along monitoring his own calibrated boost pressure gauge. We, (1957 Ford) were allowed 6# of boost @ 4800 RPM's, plus 1# of boost for every 1000 RPM's over 4800 RPM's we turned the engine. I understand Gordon Williams had to do the same with his Studebaker also. Has anything like that been done lately, or are there any boost specs on these new cars at all. Any body know?

How much HP does a 426 Hemi or 427 Chevy stocker motor make?

A good Street Hemi should make somewhere in the neighborhood of 650 HP. Don't know about the 427's.

How about when a turbo car at a alt. track sets a record 1.58 under but wait, it can't get hit because it's a alt track. Sorry almost a year later that still bothers me.

I've made mention of this issue many times over the years. It usually falls on deaf ears or the FWD brigade jumps in and then it turns into debate over what the OEM standard is (or isn't) and how boost somehow equals nothing more than blueprinting a non-pressurized engine.
The SCCA stopped the tide of MOPAR FWD cars dominating the races decades ago. They gave turbo racers pre-set, sealed & locked waste gates that were installed prior to the race ahead of the carb or injection system. I'm not sure if the waste gate was set to an OEM or SCCA standard but it took care of the issue.

[Rory McNeil]

Bill, I`ve always felt that the forced induction car should be limited to factory boost levels. Like Jeff said (and he used to run a Turbo FWD Stocker), whenever this subject was brought up in the past, it usually ended up with the Turbo FWD crying "No Fair", because turbo`s are inconsistent, or FWD cars don`t have many gear ratios to choose from, or how FWD cars are tricky to hook up, but then they brag about taking a bone stock turbo FWD car and running 1 1/2 seconds under for virtually no expense.Personally, the sealed pre set wastegate on a turbo or blowoff valve on a supercharged engine only seems fair.

Fred, I have heard the stories about NHRA Tech officials riding along with the blown 312 Fords way back when. By the way, Larry Walkers old 57 blown 312 car is still around. It`s been up here in Western Canada since the early 70`s, and is scheduled to come back out this year, after being in storage since about 1975.
One thing that I do find odd about the new Cobra Jet is that according to Georges post, it appears that NHRA knocked 75 HP from the 500 HP rating. That could be interesting! But hasn`t NHRA often "adjusted" factory HP ratings, both up & down? Like I said before, Pomona should be interesting! Seeing Jim Waldo back in a Ford is great, even if it is an automatic (for now!?)
