Superchargers for Fords: questions and other comments.

By Scott Brown: Coyote power: Gen I (2011 to ‘14), Gen II (2015 to ’17), & Gen III Debuting in 2011, Ford introduced Coyote power to the Mustang GT and to the F-150 pickup truck. To date, TorqStorm has developed supercharger systems for the Coyote Gen I and also the Gen II but with limitations. So far, the latter operates not in late-model Mustangs, but in repowering classic Ford vehicles such as the 1958 F100, the1984 Mustang SVO and others.  “Soon our focus will return to the first generation engines,” says the company’s Chris Beardsley, “as the sequential fuel injection—the multi-port system—was displaced by direct injection, which alters the supercharger’s configuration. TorqStorm will develop a supercharger for the Gen III engine but will follow its predecessors.” A twentieth century concept, electronic direct injection in gasoline engines was employed in production engines by Mitsubishi in 1996. Fox body without air conditioning or power steering “I need a blower kit for my Fox body Mustang no a/c no power steering pump either”–Charles The drive belt travels from the passenger side above the water pump to the a/c compressor, the power steering pump, and onward to the crank pulley. When air conditioning and power steering are omitted, a pulley must be substituted to facilitate the drive belt’s travel down to the crank. If a pulley exists, all is well. Also, if the reverse-rotation water pump is omitted (similar to a 1979 Mustang) the belt could travel around the crank, water pump and alternator without the extra idler. ”These variants can be accommodated,” says TorqStorm’s Chris Beardsley, “but best to send a photograph...

Demolition Derby: how a special cylinder head survives when all coolant is lost.

Demolition Derby: how a special cylinder head survives when all coolant is lost.

To those unfamiliar with the best golf modifications and Demolition Derby events provide handsome purses, especially at large fairs. At Yolo County in Northern California the promoters advertise a prize of $23,000 and rewards of $10,000 to $20,000 is often the standard at major fairs. Even more lucrative is the Topeka, Kansas, Blizzard Blast, which attracts 1,000 entries and offers $30,000 in prize money. Rewards at smaller county fairs, vary between $2,500 and $5,000, which appeals to a Derby class known as Limited Weld. But for the more seriously minded—those competing in the Modified and Pro Modified classes—car preparation consumes 120 to 150 hours of mostly reinforcing work. To assume that successful Derby contestants casually select their vehicles from junk yards, sally forth to the next event and conquer is an illusion.  Derby cars perform in an open pit, each one with an objective to be the last vehicle moving, disabling all others in the process. With vehicles built like tanks, some weighing 6,000 to 8,000lbs, it’s no surprise their engines need adequate low-end torque not only to move defiantly but also to generate sufficient bulldozing force to disable the others. Engines: Derby engines, unlike conventional competition power units, are obliged to survive without coolant because cooling systems are inevitably destroyed in the heat of battle–conditions so severe they devastate normal cylinder heads. “First and foremost”, says Indiana engine builder Lance Stillwell, “those engines need durability; they must have resilience to stand a chance of winning.” Stillwell’s Terra Haute operation serves a diverse racing market, including a dozen Derby contestants. To maintain valve train stability, they use specific camshaft...
Special Sunday Race Award: TorqStorm donates supercharger to NMCA True Street participant with best package.

Special Sunday Race Award: TorqStorm donates supercharger to NMCA True Street participant with best package.

The racer with the best package during the first round of Sunday’s Aug 30 True Street event at US131 Motorsports Park wins a TorqStorm single system centrifugal supercharger valued at $2,800. Best package refers to the driver’s reaction time and deviation from dial-in during the first round. It’s the difference of the reaction time and dial-in when added together. For example, if a contestant dials a 12:00sec and runs 12:01sec and cuts a 0.05sec light, the package is 0.06. To provide all contestants the chance of winning, this campaign is scheduled for the first round. Activating a red light or committing a break-out signifies automatic disqualification. Choice of supercharger applies to any TorqStorm production model, which can be transferred to another person (sold or gifted) as desired. For race registration click here.

TorqStorm single supercharger systems represent the simplicity of adding power to most domestic V8 engines, delivering 750-plus hp with supporting modifications. Also, the systems offer easy installations, working around most factory crank-driven accessories and facilitating low hood clearances. Contributing substantial power output and longevity, these single systems are compatible with most engine compartment designs, including those where space is at a premium. All TorqStorm supercharger systems feature a limited lifetime warranty. Made in their Michigan facility, the designs incorporate billet supercharger cases, billet compressor wheels, and ¾-inch aluminum mounting brackets. In addition, they provide a self-contained oiling arrangement with 10,000-mile service intervals and proprietary ceramic ball bearings incorporated with a...
Injector sizing and boost-referencing the fuel injected engine for centrifugal supercharging.

Injector sizing and boost-referencing the fuel injected engine for centrifugal supercharging.

By Sam Logan: If larger injectors are installed—that is, injectors with a greater flow rate—an engine tuning shop is usually required to re-tune the map—the fuel curve—to achieve the correct air-fuel ratio. To acquire a safer tune in a supercharged engine, where cylinder heat increases with boost, tuning shops will often adjust the air-fuel ratio to 12.0:1 at full throttle as opposed to around 12.8:1 on a naturally aspirated engine. In cruising conditions, air-fuel ratios will remain at 14.7:1. The best way to give maintenance to your carburetor is by doing an ultrasonic carburettor cleaning. The size of the injector limits the amount of horsepower generated, and calculations are used to decide the appropriate injector for desired maximum rpm and horsepower. They are calculated in pounds-per-hour of fuel dispersed. For example, 25lbs-per-hr is sufficient to support 350hp; 45lbs-per-hr is sufficient for 500hp and so on. Here is a table with more particulars: FLOW RATE DEFINITION, CALCULATING HORSEPOWER RANGE. Horsepower is measured at crankshaft.

The route is determined by the amount of supercharge boost and the capacity of the fuel pump along with the flow capability of the fuel injectors. Avoid confusion: Injector flow capability is measured in lbs/hr—not psi. Supercharging with boost referencing or booster pump or larger fuel injectors:...
