The next day, we hit the track at Gainesville Raceway. A few runs with Gonyon behind the wheel yielded equivalent to what it had run before-high-11.40s at 118 mph. Gonyon began looking at the data being logged by his laptop, and realized we were missing something. The power band had been moved up, requiring him to shift later.
After icing down the intake (it was almost 90 degrees out, and even hotter on track), Gonyon rolled back to the starting line and waited for the tree. The results were impressive: 11.38 at 120 mph. "Instead of shifting at 7,200 rpm like before, I shifted at 7,500. Looking at the data log, rpm only dropped to 5,200, allowing us to stay in the power band and get down the track quicker," Gonyon said. The 60-ft time was equivalent to before-1.56. And that was at 3:15 in the afternoon.
With that, we called it a day. "I think the car will run in the 11-teens with some better weather," said Gon-yon. It's impressive for a naturally aspirated Three-Valve. Not to mention the clatter the car now makes. If you're looking to give your N/A Three-Valve some extra bark and bite, these are the cams for you.
