If you followed our buildup on this car back in the June 2010 issue ("The Bravery," p. 80), you know that the results of the marriage of the Boss 330 5.4 and massive Whipple spun the dyno rollers at UPR Racing to the tune of 805 hp and 673 lb-ft of torque. Of course, the dyno was only part of the testing procedure. Lethal planned to earn its cred on the dragstrip. Naturally, it's not as simple as just bolting the combination together.

"After the build was finished and the car was custom-tuned by Jon Lund of Lund Racing, we made a visit to the track. Our first time out, we ran a low 10 but experienced some issues," Jared said. "After a little poking around, we ended up replacing the alternator and made another visit to the track. That was when Jeremy cracked off our first 9..."

Jeremy is none other than UPR's Jeremy Martorella, an experienced drag racer and professional sunglasses model, who was kind enough to lend his mastery of the manual trans to the Lethal cause. He also lent quite a bit of the suspension-tuning knowledge he's learned from the likes of Billy Glidden to help hook up the 5.4's massive power at the track. The combination of Jeremy's suspension tuning and driving paid dividends in the form of a milestone achieved-the first 9-second '10 GT500.

"Another few weeks went by and another trip to the track yielded us our quickest run so far, which was a 9.66 at 146.19 mph. All of this basically put us on the map and earned us some good street cred in the GT500 community," Jared added. "Not bad for some 'parts guys' in south Florida.

"At this time we've made a few changes to the car. Most importantly we've switched over to E85. We're looking to raise the boost to make more power and crack off an 8-second pass with the stock TR6060 six-speed." If that goal weren't lofty enough, the Lethal crew recently acquired a Grabber Blue '11 Mustang GT, and they're looking forward to pushing the Coyote-powered Pony to new heights as well.

We know where this is headed. Another Mustang is going to take a beating in the name of performance, and we're going to love every minute of it.
