The CP Carrillo-backed Top Alcohol Funny Car pilot left the starting line with a psychic .029-second reaction time and kept right on going for a 5.425, 269.67 win over Swede Ulf Leanders’ 5.508, 268.33. Aggressively testing in Phoenix prior to the Winternationals paid off for Top Alcohol Dragster driver Shawn Cowie, who scored his 11th national event win and second season-opener Wally with a defeat of Garrett Bateman.
Upgrading a few bolt-ons at the same time makes sense. Here are some popular choices. (Note: In the links below, sort by year, make, and model to find the right part for your vehicle.) With stock pulleys, the blowers spin around 16,000 rpm at redline. Changing the pulley sizes can spin it faster and increase boost. The next step on the upgrade path is a pulley swap. The chart below will give you some idea of what to expect.
Larger-capacity aftermarket fuel rails are also at risk for these issues, especially in boosted applications where an underhood turbo or supercharger is creating more heat for the rails and the fuel inside them to absorb. Seeing the problem at hand, Heatshield Products developed its FR Shields™ to combat this issue by wrapping the fuel rails in a deflective thermal barrier that keeps radiated heat from soaking into the rails (whether they be aluminum or other alloy) and heating the fuel inside the rails.
I would like to get about 350 hp out of the new engine and run in the 13s. Is this possible with my combination? Your crate 350 should be okay for use with a TPI system. We recommend checking the engine’s camshaft specifications. Most “computer-friendly” cam profiles are no bigger than 214-222 degrees duration at .050 and .450-.460 inches of lift with 112-116 degrees of lobe separation. If the cam in the new 350 is much over these figures, you should consider a different camshaft to ensure compatibility with the IROC’s computer.
