“Words cannot describe this,” Will said, after defeating veteran racer Kyle Seipel in the final, 6.043 (6.01 dial) at 234.13 to 6.862 (6.81), 197.74. “I’m totally excited, and there are so many people to thank for helping me get to this point. I have to thank the fans for showing up. It makes it even more special.”
Fuel injectors and the rails that hold them are just as susceptible to heat issues as the carburetors they replaced. Located on top of the engine, fuel rails see a lot of heat exposure. On late model vehicles this issue is further compounded by how compact and tight modern engine compartments tend to be, along with the factory engine covers that are all the rage these days, trapping even more heat that can be transferred to the fuel as it flows through the rails on its way to the injectors.
The factory heads are based on the LS3 heads. However, they have a flow vane in the intake port. This helps emissions and idle stability, but reduces flow. CNC porting the heads is common. This removes the vane and improves airflow by about 70 cfm. Aftermarket cylinder heads are another option. These heads will flow even better than ported stock heads and have thicker deck surfaces to withstand more boost.
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.
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.
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 Winternationals Super Comp money round was historic as it marked the 13th brother-vs.-brother final in NHRA history. Gabriel Torres took the win over his brother, Val Jr., with a .035-second reaction time and 8.922 at 165.46 on the 8.90 index to a .024 and 8.941 at 176.26.
Unless your pet is a kangaroo, they might struggle to get into a vehicle with a high deck height, like many trucks and SUVs. That’s where pet ramps come in handy. They’re available in a wide range of sizes and most fold compactly and can be stowed away, so you can bring the ramp with you.
