Dynatech Headers is proud to announce the launch of our new Torque Booster. Dynatech now has a solution for those times when you need that added torque on restarts. Many times it's the restarts that determine the win or loss of a race. This new device works especially well between 2500 & 4200 RPM on engines with under 500Hp at the crankshaft. Although beneficial on almost any engine under 500 Hp, they work exceptionally well on 602 and 604 Crate engine applications where the added low end and midrange torque gains are needed. Usually when you pick up low end torque, it is traded for some high end horsepower. The Torque Booster defies this rule and provides substantial increases in low to mid-range torque with no effect on the high end horsepower numbers. The Dynatech Torque Booster is a great way to pick up some low end torque on many engines. Typical gains are in the 10% range. Overall length is 8.00" in which 2.00" slips over your existing pipe. After installation it will add 6.00" to your exhaust system.
