Detonation can occur if inlet air temperatures get too high and/or low-octane fuel is used. This will destroy the cast pistons in the LSA. Forged pistons are a smart upgrade. (The LS9 came with forged pistons from the factory.) Due to extremely high cylinder pressure, the heads can start to lift around 1,000 hp. At that point, you will need to basically build a whole new engine. The following upgrades will be required.
The LSA came equipped with rectangle port (LS3-style) cylinder heads. However, the supercharged heads were Rotocast for added strength. The engines also use the same 4.065 in. bore block. In fact, the engine block casting number is the same as the LS3.
Cowie surged ahead with a victorious 5.333, 277.03 as Bateman smoked the tires at the hit of the throttle. During World War II, long-range fighter and bomber aircraft were equipped with “Belly Tanks” or “Drop Tanks” full of fuel which extended their range for long-distance flights. After the war, the tanks’ streamlined housings became the go-to choice for hotrodders looking for an aerodynamic body for their Salt Flat racers.
Auto Club Raceway at Pomona became the site of Dan Fletcher’s 103rd national event win at this year’s NHRA Winternationals. “I’m always on a mission, it’s just whether you get lucky and the Lord blesses you and you get the win, that’s all,” Fletcher said, following his victory over a red-lighting Clint Neff in the Competition Eliminator final. “This weekend it worked out. We were really fortunate, and we won. Our chances weren’t great, but there’s just so much luck involved in this. We got it done.”
