FREQUENTLY ASKED QUESTIONS
Q: I am interested in purchasing a shifter for my car and I don't know which model I want to choose? manual, air or electric
A: The first question you have to ask your self is what class are you going to race in and if that class allows you to use the shifting system of your choice.
About Manual Shifters: manual shifters are designed for the entry level racer which allows racer to have the same quality as our premium models at a significant savings. All of our manual models allow you to retro fitting any existing the shift system you may have with little or no modifications.
Q: The class I intend to race in allows the use of an air or electric shift system, which shifting system would you recommend for me?
A: This is a matter of personal preference, each have there pro's and con's.
The Pro's and Con's of an Air Shifting system:
The Pro's: An air system can make a good choice for many reasons first being if you are running a co2 throttle stop you can tap into the existing line. The second reason is that an air system is generally lighter than an electric system usually by about 2 lbs. The third reason is that an air system is a lot more compact, another feature desired in classes like Comp Eliminator where driver compartments are tight. The fourth reason is the air solenoid we use draw only 1 amp. using less power from your battery.
The Con's: An air system can have many drawbacks as well, first you can develop an air leak making the air system inoperable or you can forget to turn on the bottle, no air no shift. Secondly if you choose to use air instead of co2 you will get approx. 200 shifts form an air system vs. approx. 500 from a co2 system. Third reason not to use an air system is condensation build up this condition occurs when condensation builds up in the lines causing the system to malfunction. It is worth the extra money for a co2 system to make sure this doesn't happen to you.
The Pro's and Con's of an Electric Shifting System:
The Pro's: There are two different types of solenoids available Push or Pull.
The Push style solenoids draw the most amps. of all, depending on how much force it takes to move the shift levers will determine how many amps. the solenoid will draw. If your cable is kinked or bent to tight it will cause binding which will make the solenoid to draw more amps or not shift at all. This solenoid operates on a normally open circuit and usually requires a relay in order to operate.
The Pull style solenoid is the one of the best solenoids available, a real work horse. If you are looking for reliability then look no further, this solenoid is for you. The plunger has a cap with a spring behind it, when the power is on and you pull the shift lever onto low gear the plunger is held in place until the power supply is broken causing the shift lever to spring forward into the next gear. This solenoid only draws 1 amp.
The Cons of an Electric Shifting System
The Con's: Of the two styles of solenoids available the Push style has had the most problems. The first problem is that it draws to many amps. Another problem is that some companies use reworked starter solenoids that are not properly designed usually falling apart. The only draw back of the Pull style solenoid is that it must be manually cocked in order for it to function.
