By V. Moore: Conventional carburetors operate at prevailing barometric pressures, from oxygen-rich sea level to oxygen-lean Denver, a mile high in Colorado. Blow-through carburetors, which work in conjunction with centrifugal superchargers and turbochargers, operate with boosted pressure. It’s a contrasting concept that accelerates the induction process. It impels higher velocity fuel flow through the main jets and robustly emulsifies the air-fuel mixture in the metering passageways, as it makes its way to the carburetor’s boost venturii. The boost venturii are carefully positioned in a choked area, an area with a reduced cross-section to increase the air speed. Increased air speed lowers the air pressure at the small discharge orifice in the booster, extracting the air-fuel mixture into the air stream on its journey to the cylinders. When boost pressure enters the fuel bowls, via the two vent tubes, its force lowers the fuel levels and quickly becomes so potent with increasing engine speed that the needle-and-seat valves cannot keep pace with demand. To keep the carburetor flowing relative to boost, the float bowls must be pressurized. As boost pressure increases, fuel flowing through the metering systems increases proportionally. Further, as the float bowls are pressurized, the fuel pump must overcome that boost pressure (as opposed to the naturally aspirated condition of pumping fuel through the needle-and-seats into float bowls that are vented to atmosphere). If 7psi of fuel pressure were employed to a normally aspirated engine and 7psi of boost applied to the float bowls, the pressure in the float bowls and the pressure from the fuel pump would be equal, causing zero fuel to flow through the needle-and-seats. So,...

By Sam Logan: Naturally, there’s a desire within the TorqStorm operation to introduce enthusiasts to their billet supercharger. But also there’s a keenness to acquaint them with the racing scene, especially those with no former competition experience. So 2020 marks the beginning of a new era for TorqStorm, an initiative with the NMCA to sponsor their well-established True Street class. True Street rules call for the entrants to take a 30-mile cruise followed by three successive drag strip passes. As a special feature for this event, they were led by Drag Week winner Tom Bailey and his Camaro with YouTube celebrity Cleetus McFarland occupying the passenger’s seat. The race results were as follows: Mike French triumphed, motoring to an overall win with an 8.77sec average, while Jason Rollins claimed runner-up, finishing with an 8.96 average. Willard Howard was the tour de force in the 9-second category, Jeff Smith the 10-second, and TorqStorm’s own Jeff Neibarger was the 11-second winner. Grant Martin won the 12-second category, with Jose Vera and Jimmy Hodges winning the 13-second and 14-second categories respectively. Branden Arila took the spoils in the 15-second...

By Archie Bosman– Kennesaw, GA: Using the correct flow valve: Electric steering in mass-produced road cars is now widespread. It is a little like ethanol in our fuel: you’ll be hard pressed to find an enthusiast who favors it yet we are stuck with it. But actually we aren’t. Hydraulic power steering systems that provide superior feel are still readily available to the racer. However, it is not widely known that steering pumps can be tuned for more feel or alternatively for more assistance. Optimizing feel to the racer’s steering is a bewildering task for most of us. But KRC Power Steering accomplished it by introducing a range of replaceable flow control valves for their hydraulic steering pumps. The flow control valves, nine in number, perform a function similar to that of jets in a carburetor. In varying their flow from 4 to 12 liters per minute, approximately one to three gallons, the largest orifice provides maximum steering assistance while the smallest provides maximum steering feel. Though the standard KRC pump flows 8 liters per minute, by using flow control valves with larger orifices, those marked B, C, D, or E, the flow rate can be increased to 12 liters per minute (3.17gals) in one-liter increments. The higher letter indicates greater hydraulic assistance, although less feel. In contrast, flow valves marked with numbers 4, 5, 6, and 7 provide less assistance; the lower the number, the greater the feel but the less assistance. Momentary loss of power or “pump catch” So how do you achieve optimum steering feel? According to KRC’s Ken Roper you reduce the size of flow...

Since TorqStorm’s beginning, about ten years ago, inquirers have written on virtually every aspect of forced induction. Oil-changing procedures is a popular topic. Required at 10,000-mile intervals or once a year, whichever comes first, here are the four steps with pictures and captions to clarify. Step 1 Remove your supercharger from your car and flip it over onto backside to access drain plug. Step 2 Remove drain plug with 1/4in Allen wrench and drain oil. Step 3 Through the drain hole, pour 6fl oz of TorqStorm-specific oil. Step 4 Replace drain plug and tighten to 15lbs- ft of torque. An oil change must be performed every 10,000 miles or once a year, whichever comes first. Failure to do so will void the warranty. Oil can be purchased directly from TorqStorm for $6: Part# ARP-OIL-GT46 TorqStorm SuperchargersTorqStorm.comTelephone (616) 706-5580 or visit www.TorqStorm.com or e-mail the knowledgeable Chris Beardsley...

In 2020, TorqStorm will participate in a new campaign, sponsoring NMCA’s True Street, a quarter-mile drag racing class for grass-roots enthusiasts, including those who have never raced before. The racing campaign promises to be a welcome addition, particularly the early March event for those who enjoy a little racing and an early vacation in the sun. With scarcely time to draw breath following a busy 2019 season of shows, developing new supercharger applications, moving to larger premises, and managing increased production schedules, 2020 is hoped to be a landmark year. Both TorqStorm co-founders, Chris Brooker and Scott Oshinski, plan participation at all six NMCA racing venues as well as the two LS Fest events and perhaps two Mopar adventures (Hemi Fest at Summit Sports Park, Norwalk, and Mopar Nationals at National Trails Columbus). The True Street calendar of events is as follows: March 5-8 18th Annual NMCA Bradenton Motorsports Park Bradenton, FL April 2-5 12th Annual NMCA Atlanta Dragway Commerce, GA May 28-31 Inaugural NMCA Technology R’way, Gateway Madison, IL July 30-Aug 2 15th Annual NMCA Route 66 Raceway Joliet, IL Aug 27-30 19th Annual NMCA Summit M’Sports Park Norwalk, OH Sep 24-27 19th Annual NMCA Indianapolis Raceway Park Indianapolis, IN NMCA’s True Street class permits enthusiasts to race on premium tracks at a cost of $125 over the course of three days, (Thursday is regarded as set-up day) and the average car count for the class numbers around 50 but can climb to 125 at some venues. Prizes are awarded to the overall winner and runner-up. Prizes are also awarded for the best 9-second average, 10sec, 11sec,...

Following ten years of supercharger manufacture, TorqStorm has developed approximately 100 variations, which, of course, increases to 300 variations when three choices of finish are included. Chris Beardsley of Technical Sales elaborates, “Consider our small-block Chevrolet kits, for example, these are available with left- or right-hand mounting and with long- or short-style water pump. They are also available in single or twin configurations as well as our comprehensive Plus kit. In addition, there are two different twin kits: a regular twin and a 2XR kit—and all of these represent just our small-block Chevrolet offerings!” Future developments? “The Hemi guys,” says company co-founder Chris Brooker, “regularly inquire about complete kits; that is, a turnkey kit that provides a tune, injectors, cooler, and piping. When we eventually pursue the development of these, we will probably first focus on the Ram truck, Camaro, Pontiac G8, Pontiac GTO, and Silverado. At the moment we have these—about six or eight kits available—but they are incomplete and non-smog compliant.” Source: TorqStorm SuperchargersTorqStorm.comTelephone (616) 706-5580 or visit www.TorqStorm.com or e-mail the knowledgeable Chris Beardsley...
