KOTS celebrates its 10th annivesary
2007 Shelby GT500
We didn't know much about Jammye McQuade and his GT500 prior to KOTS. All we knew was that he was basically a SVTPerformance.com legend. He sent us a link to the famous website--several pages long--featuring the build on his car. A small army of Mustang enthusiasts were eager to hear Jammye's next move, and so were we. A built bottom end boasting a Kenne Bell 3.6-liter liquid-cooled supercharger and a stick, and Jammye actually regularly drove the car...how could we pass it up?
This was also one of several owner-built KOTS cars with little shop influence. Jammye did rely on Lee Blankenship from Blankenship Tuning and Performance to do the tuning on the car, but the mechanical aspect of the car--including putting the engine together, except for the MMR 1500 short-block--was handled by Jammye and a few friends. He relied on the advice of those in the know to get the Kenne Bell 3.6-liter supercharger under the stock hood. Through trial and error, he had a beast on his hands.
Only seeing a couple photos of Jammye's car leading up to the competition, we didn't really know what to expect when he cracked open the trailer. We shouldn't have been worried at all. Jammye's Shelby was top-notch. It looked racy from the outside with the big 'n' littles, but those fears were likewise put aside on the Ride & Drive. The car features stock seats, stock seatbelts, and overall, it was fun to drive.
Jammye's young son Jesse rode along on the Ride & Drive, and he fell asleep about halfway through the short trip. Jammye and I turned the stock Mach 500 stereo up to 11, and Jesse slept unfazed. I hammered down on the throttle through a few gears, but that didn't affect Jesse either. He slept on.
I was impressed. The power was so linear, different than the other positive displacement supercharged cars in KOTS. The car took off under the Kenne Bell's power and the grip of the Mickey Thompson ET Streets. However, it seems the car should've had trouble getting grip. The next day at Holley for the Horsepower segment, Jammye was unlucky, drawing the Number 1 spot on the dyno.
From the dyno room right behind Holley's Dynojet, I could tell the car wasn't quite right; "only" making 709 rwhp, Jammye also knew something was amiss. The car seemed to be sputtering or missing, and you could see it on the dyno. He soldiered on, and for the second dyno pull the car made 759 rwhp. Jammye was expecting around 900 so 759 couldn't be right. He didn't know what the issue could be or whether something happened to the tune. He was at a loss.
Though he didn't say anything to me at the time, Jammye thought I wasn't giving the car the 'what-for' on the street. It felt pretty fast to me, but Jammye didn't think I was all in. Unfortunately, he didn't have a chance to give the car a look-see until after the Drag Race portion of the competition. He was right; something was amiss with the car. A pre-KOTS engine cleaning with Simple Green resulted in water getting into the coils, causing a misfire.
Jammye and a friend removed all the coils, changed the oil, cleaned out all the leftover liquid, and took the car for a test drive. Of course, the car was running under its full capabilities at that point, but it was too late to apply them to any KOTS results. However, to illustrate the difference, Jammye ran a best of 11.03 for the Drag Race category, but while running in the Cobra-GT500 shootout as part of the NMRA World Finals, he cracked off a 9.97.
Jammye's final KOTS score would've been a lot different had his car been sorted out prior to the Horsepower and Drag Race portions of the competition, but it is what it is.
