Overview

Biondo Spare Air Solenoid Cylinders

Sam Biondo Racing spare air solenoid cylinders are components used in drag racing applications, primarily with air/CO2 shifters and throttle stop controls, to provide consistent and precise pneumatic operation. Biondo solenoids are known for specific features, such as low current draw in electric versions (around 1 amp) and designs that resist false activation from hard vibrations. They're available in square or cylindrical configurations, depending on the specific application. These replacements are manufactured by racers for racers, following the philosophy of creating durable, high performance products that solve real-world racing needs for improved consistency and reliability.

Key features and uses:

* These solenoids act as an electric-over-air (pneumatic) valve that is activated by an electrical signal (usually from an RPM-activated switch or delay box). This activation controls the flow of compressed air or CO2 to an air cylinder, which then physically shifts the transmission or engages/releases a throttle stop mechanism.
* Applications:
-- Air Shifters: Used to provide consistent, repeatable shifts activated by a set RPM, rather than relying on manual shifting
-- Throttle Stops/Starting Line Control (SLC): Used to control engine RPM at the starting line or during a race for consistency, particularly helpful in "Crosstalk" bracket racing
* Components: They are part of a larger system that typically includes:
-- A CO2 bottle and regulator
-- The air cylinder itself, which performs the mechanical action
-- Tubing and fittings
-- An RPM-activated switch or a delay box
