progressive shots are bad for the solenoids, just go with a straight 300 shot

 

ressurecting old threads is bad for the world.

and a "straight 300" shot is hard on the motor. I'd rather replace a solenoid every/every other season then replace a motor every other season.

 

This will depend on the solenoids you are using, and how you are using the progressive.

My solenoids are over 5 years old and have countless passes on them. I have been using a progressive fro the last 2 years. My solenoids have never failed nor have they needed to be rebuilt.

My progressive is set to cycle the solenoids at 15 cycles per second. I typically ramp for 50-75% to 100% in .5-1.5 seconds. This will have the solenoids pulse 8-12 times per run.

As long as you are using a solenoid that has been designed for a progressive, and are not using the progressive for "horsepower" control, I see no reason the progressive is going to cause a solenoid failure. Now you should periodically check the solenoid for wear, but that should be done with or without a progressive.

 

and if the solenoid sticks open? youll be replacing the motor and the solenoid.

 

I believe ray covered that in the 4th section of his post

 

Solenoids fail, in the closed position. The only way they "stick open" is from an outside influence. Either a foreign particle jamming it open, or a swolen plunger from using the wrong fuel with a given fuel solenoid.
