what does it matter if its 10Hp, or 200Hp underfactored, whats the point. Since the inception of NHRA , there HAS always been combos that are underfactored!!!!!!!!!!!! There are some that are overfactored.

Does this mean you think the 08 Cobra Jet should weigh 4485 LBS to race in AA/S or AA/SA or 4770 LBS to run A/SA or A/S ?



D French wanna be racer with a car but o no $$$

Re: SS/E 2008 Mustang at Atlanta
 

You are trying to add 150 horsepower to the nhra factored horsepower. That's not the way they do it. A fair rating for this motor should be no less than it's three valve cousin @510.

Re: SS/E 2008 Mustang at Atlanta
 

What's the point? The point is "grossly" (150 horsepower) under factored and you can't name one.

Re: SS/E 2008 Mustang at Atlanta
 

The cobra jets are rated at the same horsepower rating as the baddest muscle car engines in the 60's, the 427 ford and 426 Hemi and the 427 chevy. Don't you think it is a bit extreme to say they are 150 horsepower underrated when they are only 330 cubic inches? Robert Ponds AA/S Fairlane was faster at Pomona than the Cobra Jets were. Until some one runs fast enough in competition, I don't think you have a leg to stand on.

We made several changes to run SS, 4 cams, bigger tires and removed the alternator. On the first run the shifter hung up on the 4-5 gear change. On the second run the car rolled out of the beams. We finally got some good data captured in the Racepak on the third run which was a 9.91 @ 139.07. We determined that the clutch was too agressive. We then proceeded to take too much clutch out for class on Friday morning and went 9.88 @ 136.55. We then split the difference and tightened the clutch back up some for first round on Saturday. We dialed 9.98 for first round. Jmmy had Mike Saye on the tree, but took a little too much stripe. Looking at the data in the Racepak, it looks like we are pretty close on our clutch now. But that's all subject to change when we re-configure the car back to Stock.

We have the car apart now and don't plan to race again until the Norwalk divisional.

Look for another CJ in Super Stock at the Indy divisional.

Re: SS/E 2008 Mustang at Atlanta
 

Thanks George, It looks like you guys should be very competitive in AA/S
Good luck!

Re: SS/E 2008 Mustang at Atlanta

Re: SS/E 2008 Mustang at Atlanta

Bruce,

I give, you win this one as I don't know what else to say. I hope you and every other person who lays awake at night wondering how this abomination of an animal is allowed to compete on the hallowed ground of natural stockers get's there wish that the cobra jet is refactored to 1250 hp at the wheels no less. It will be destined to compete in Pro Stock by the end of the year.
