I have seen some big numbers out of the Cobras, 2003 models. But, they can never seem to get very good 1/4 mile times. One I saw hsa 600rwhp, and he got a whole 12.2-112mph. One had a 455rwhp and ran a 12.1 118mph, then the other has 507 and ran a cool 12.6- 113mph. The speed usually is a good sign of HP. My 4o0 rwhp runs 11.9 at 118.5 all day. So are these dyno numbers real? They all run Nitto drag radials.

 

depends on where they did the numbers, as im sure u know elevation kills horsepower

 

In Hawaii, which there is very little elevation.

 

hmm no clue bad driver possibly???

 

Three letters....IRS That kills the 60ft times. If they want to get any faster they need to swap out to a solid axle.</P>

 

2 of them are getting ready to do it. One of them is the silver "quartermileperformance " Mustang from there website, whic si for sale now, for 36K

I thinl allot is driver error, but the speeds dont really match a 550-600rwhp car, that should be over 125mph easy.

 

60 ft. times is where they lose it that and traction issues
