two solenoids on one spike?

[Chara09]

Anyone know the exact ruling on wiring two double solenoids on one spike? I can't seem to find any documentation on it.

I believe this was allowed by a Q and A response las yesr.

It's allowed by the rules this year. "Light" loads may go multiple to one Spike.

My question is Why would you want to do this? Please explain what functionality you are trying to achieve as there is probably a different (less weight) way to do it.

The spike user guide on IFI explicitly describes how to control the functionality of two solenoids using a single spike relay.

A reason Our team is doing it is to fire both transmissions at the same time with two small pistons on our Super Shifters.

The question was two double solenoids, which is really 4 solenoids.

That is what I thought. You do not need two double solenoids to achieve this. Just use one solenoid and use a T to send the air to both pistons. This will get you much better performance and you save the weight of the extra double solenoid. We have shifters and this is exactly how we are doing it.
