The nitrous was also bumped to 175 horse-power before the Goat took to the rollers again. According to Bill, it generated an outstanding 657 hp and 732 lb-ft of torque on nitrous and 457 hp/443 lb-ft naturally aspirated.
Both Bill and Bob felt the nitrous numbers were a little risky on the stock bottom end. They made adjustments to the nitrous to bring the torque below 600. The final result was 596 hp and 592 lb-ft of torque, just where Bill wanted to be. "I think the car has more than enough power to bring me into the 10s now," he quips.
Bill's tuning was previously done by Jeremy Formato at Fasterproms in Tampa, but he got tired of having to make alterations to his tuning because of his nitrous setup. "I was very happy with the tune on the street but I had to have it retuned if I wanted to spray the nitrous," he adds. "So I wanted to learn how to tune the car myself." He enlisted in The Tuning School's Tampa seminar to learn everything he needed to know about how to use engine-tuning software like HP Tuners. The class actually used Bill's GTO as a testbed for a true hands-on experience. He now has the luxury of tweaking his control modules as he sees fit and no longer has to worry about making a sacrifice for a street or a track tune.
Many late-model GTO owners complain about trunk space. Bill found it to be rather accommod
Since the power numbers had swelled, further attention was placed on the chassis. The drag bags were a big help, but there was still more to be done. Up front, Precision Motorsports installed a BMR strut-tower brace, Pedders HD strut mounts, strut bearings, and radius rod caster bushings. A pair of 5/16-inch raised rear coil springs, GSR shocks, and X-member bushings complete the rearend setup, while new sway bar bushings all around improve cornering. When all the work was done, the rear cradle was aligned and Bill was on his way.
On the street, the GTO wears a set of factory 18-inch wheels that were chromed by Courtesy Pontiac in Tampa. They're shod in 235/40-18 BFG G-Force Sport tires up front and 275/40-18 Falken FK-452 in the rear.
What's In Store?
Now that the GTO is dialed in, the 52-year-old Pasco County Deputy Sherriff is gunning for a 10-second timeslip. His previous best came at the 2008 All GTO Track Day with his old camshaft, LS2 intake, and BMR Drag Bags. On 275/40-17 Mickey Thompson Drag Radials and shifting at 6,300 rpm, he went 11.2 on a low 1.60 60-foot, spraying out of the hole and at a race weight of 4,100 pounds. Later in the day, during eliminations, he launched the IRS-equipped GTO perfectly and was rewarded with a 1.59 60-foot. This ended up being the best 60-foot by any manual transmission Goat at the event and he was given a trophy to commemorate his achievement. "I just bring the rpm up to 3,500 or so and then bring the clutch pedal out just prior to engagement. When the tree drops I give it a quick release and off I go," he comments on his launch technique.
Bill is confident that his power level and driving experience will pay off with a membership to the 10-second club in the near future, which will certainly confirm that plenty of spice has been added to his GTO.
