Fortunately for Josh, the previous owner already installed a 4.10:1 rear gear set. Though stronger than the early '99 and '01 Cobra halfshafts, Josh figured the factory '03 Cobra axles wouldn't survive, so he replaced them with a pair of The Driveshaft Shop's Level 5 halfshafts with chrome-moly inner CV joints. Josh didn't ignore the other driveshaft, as he replaced the OEM aluminum piece with a carbon-fiber unit. Finally, to "keep the pumpkin's guts inside" when launching on his 315/35-17 M/T drag radials, Josh added a Steeda differential cover brace.
Up to that point, Josh's best quarter-mile times were a few 12s at over 122 mph-launching at idle on street tires! With more power than ever under the hood and heavy-duty hardware throughout, Josh was ready to see how quickly his Snake could slither. At an SVT drag day, Josh got his chance. Shoe'd with his sticky Mickeys, Josh nudged the Cobra to the starting line and brought the revs to 4,500. When the tree went green, Josh dumped the clutch-but instead of launching, the Terminator snapped one of the halfshafts in half! What a letdown!
Josh replaced the broken axle, but at the time of our photo shoot, he was waiting for a few other parts before he could re-dyno the car and attempt another run through the quarter-mile gauntlet. A Fore Triple Hat with three Ford GT fuel pumps, an octet of FRPP 80-lb/hr injectors, and a Modular PowerHouse supercharger inlet were recently added.
Unfortunately, these additions made Josh's Cobra so temperamental, it wouldn't even idle. After spending months unsuccessfully diagnosing the problem, Josh was fed up. He considered selling the car. Fortunately, Eric Brooks of Brooks Speed came on board and was able to tame Josh's potent combination.
Drinking 93-octane pump gas and breathing 19 psi, Josh's Snake spit out a solid 704 hp and 662 lb-ft of torque on Brooks Speed's Dynojet
With so much venom beneath its subtle skin, Josh's Cobra strikes ferociously when provoked. So if you're in town, you better watch where you step.
