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.
Like other LS engines, a cam swap is common. The LSA has a very small camshaft. Upgrading to a LS9 camshaft is worth about 30 hp, however, it won’t make more power until 4,800 rpm. It’s really only worth it if you plan on running at high rpm. Larger, aftermarket cams can add about 50 hp. Going as high as 0.630 in. of valve lift is also common. The table below gives some information on what to expect from different cams. (Note: We are assuming a standard blower, pulleys, and tune on pump gas.)
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.
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.
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.
With little more than a chassis, engine, wheels, and seat, these belly tankers (also referred to as “Lakesters”) demonstrated their capabilities at land-speed events and became common sights at places like Bonneville. The beauty of these racers is the sheer simplicity of design combined with the ingenuity involved in re-purposing existing components to create something better than the sum of its parts.
More importantly, the video will show some simple tests you can do to make sure your mass airflow sensor is the cause of your problem, so you don’t waste money by replacing perfectly good parts. Think because your engine is fuel injected you don’t need to worry about heat causing you problems and stealing horsepower?
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.
