Granatelli Guides

The Granatelli hot rod legend now applies to your fuel injected car, since you can get high tech sensors and components for your ride

A Granatelli mass air flow sensor acts like a larger throttle body for your car, allowing more air into the system

Granatelli MAF sensors are regulated to work with high-flow cold air intake systems, keeping your car's computer happy

Don't bore out a stock MAF sensor: Upgrade to a Granatelli MAF sensor to ensure proper functioning in your injection system

Times are a changin' when we start talking about the high performance Granatelli mass air flow sensor. It used to be carburetors, then we stepped up to throttle bodies, and now there's a Granatelli mass air flow sensor to replace your slow, stock sensor. We were skeptical at first, but after seeing an additional 10-23 horsepower, we decided to take a close look at the Granatelli mass air flow sensor. Like a larger throttle body, the Granatelli mass air flow sensor improves power in part by flowing more air than its stock counterpart. Smoother ductwork, fewer restrictions, and a larger bore size all contribute to this additional airflow on the Granatelli mass air flow sensor. However, the electronics used in a Granatelli mass air flow sensor are also improved over the stock unit. Since a Granatelli mass air flow sensor is specifically calibrated to your car's engine and improved components are used, the Granatelli mass air flow sensor is actually able to respond to changes in throttle position and airflow much more quickly than a stock sensor. The result is that you get faster acceleration, vastly improved midrange performance, and all with no loss in idle quality. The Granatelli mass air flow sensor is even 50 state legal, so check them out and pick one up for your vehicle.

r works and what it does? Well, for fuel injection systems like most of us have nowadays, the more information sent to the computer the better. The Granatelli MAF sensor (for mass air flow) lets the computer know just how much air is streaming in the intake duct. You know all those fancy cold air intakes you've been experimenting with? Well the Granatelli MAF sensor lets your car's computer know how much air you're adding, and how much the engine is pulling in. The thing is, a factory mass airflow sensor is only so bigin other words, there's a finite amount of air you can pull through it, limiting your potential power. A Granatelli MAF is bored larger than factory so your theoretical maximum power output increases. Now before you get the wise idea to take a Dremel tool to your factory MAF sensor, keep in mind that the Granatelli MAF is calibrated to work specifically with it's diameterjust like your factory sensor. Drill it out and you're asking for a check engine light to join you for the drive. Upgrade to a Granatelli MAF sensor instead and increase airflow the right way. Coupled with a cold air intake and an enlarged throttle body, a Granatelli MAF sensor can really add a lot of air to the system.

Complete mastery of your electronic fuel injection systemand your electronic ignition and transmissionis as close as the Granatelli Predator programming device. Stop suffering at the mercy of factory engine settings. You're not your grandmother, so why should you have to drive a car calibrated for her. The Granatelli Predator plugs right in to your computer diagnostic port and opens up a whole world of tuning options for you. You can set fuel and ignition curves with the Granatelli Predator to take advantage of the aftermarket speed gear you've installed. You can customize shift points in your computer controlled automatic transmission thanks to the Granatelli Predator. Heck, the Granatelli Predator can even adjust the temperatures at which your electric cooling fans come on. That's a lot of power, and a lot of power is what you can see at the rear wheels courtesy of your Granatelli Predator. But what happens when you're having car trouble, rather than looking to improve horsepower? The Granatelli Predator makes itself invaluable here too. You just plug the Granatelli Predator into the OBD port and it lets you view, scan, and delete trouble codes stored in your car's computer. You can diagnose your problem with the Granatelli Predator, fix it, then get back to using your Granatelli Predator to drop your quarter mile times. Now that sounds like a good use for a computer.

Granatelli: Over 25 Years of Experience in Manufacturing Aftermarket Performance Parts and Accessories

Granatelli Motor Sports (GMS) was founded by J.R. Granatelli in 1989. Headquartered in Oxnard, California, the company designs and builds a range of aftermarket performance automotive parts and accessories. GMS not only distributes these products but also offers professional installation. Over the years since it was established, Granatelli has become one of the trusted aftermarket brands. It has reached this status because of its formidable engineering background and acclaimed expertise, allowing it to manufacture highly dependable computer-based electronic components, which include mass airflow sensors, diesel modules, computer tuners, flash tools, and suspension systems and parts.

Granatelli has introduced a good number of breakthroughs and innovative designs through the years, and this has made it a well-established brand in the market. It has released many firsts such as the first aftermarket F-body torque arm and the first Gen 4 F-body calibrated 200 mph speedometer. As an innovator, it has also produced the Novi-2000 supercharger with over 1,000 hp capability. It's also the first to manufacture a centrifugal supercharger system that's street-legal in 50 states. The company has provided the market with solutions for growing performance demands, featuring products such as the S197 calibrated mass airflow, complete suspension systems for Mustangs, Camaros, and Corvettes, and single and twin turbocharging systems for American muscle cars.

High-performance mass airflow sensors

One of its many acclaimed products is its mass airflow sensor. This sensor is designed to increase the airflow by up to 60% compared to the OE. This is why it's considered a performance enhancer by some car owners and vehicle enthusiasts. While a stock MAF can limit the performance of larger valve cylinder heads and new camshafts, the Granatelli mass airflow sensor can help boost performance. It allows the engine to breathe easily with more air flowing through it and make it easier to generate power in the process. Its chassis dyno has proven that this sensor can help the vehicle gain about 8 to 25 hp. It can improve performance further by allowing more accurate calibrations with changes in engine intake inflow, fuel, and spark timing. This is built to be compatible with many aftermarket equipment and electronics. This is calibrated for use with a cold air induction system.

Dependable ignition coils

Granatelli is known for its innovative designs and superbly engineered products, some of which are geared towards improving performance and not just for restoring function. Such products include Granatelli's ignition coils, which are designed to increase spark plug power by up to 400% compared to the stock. These are built for enhanced mileage and throttle response as well. The coil packs can generate 40,000 more volts than the OE counterpart. Horsepower gains from using these coil packs can be up to 15hp for normally aspirated applications and up to 25 hp for S/C, turbo, and nitrous applications. These coils are built using high-temp silicone boots. With patented protector rings, RFI/EMI interference won't be an issue. The patented design is compatible with all fuel injection systems. It's also safe for use with the OBD-II computer. The pack may come with a solid stainless steel connector cable, stainless snap lock spark plug connectors, and other needed hardware.

High-quality fuel pumps

The company also designs and manufactures performance fuel pumps using all-new components. These pumps are designed to boost the fuel system performance and help the vehicle generate extra horsepower with less stress. Like other products made under this brand, these fuel pumps underwent engineering evaluations and precision testing to ensure performance, quality, fit, and durability.
