Air shifter
 

I am working on a NSS Plymouth that has a Biondo air shifter mounted on a Cheetah shifter for a Torqueflite. What activates the solenoid - does that work off a timer? Car has a 7AL3 MSD box. Not familiar with these shifters. Any help would be appreciated.

Rick, you have a rpm controled switch output on the 7AL3.
Just pick your shift point and use the proper chip in the shift rpm socket.

So it will activate the 1-2 and 2-3 shift from the MSD?

Re: Air shifter
 

There is two parts to that system, the air shifter, and the controller. You should be able to control the shift rpms independently. I think the controller uses the tach signal from the MSD.

No solenoid, no air bottle, no rpm switch needed!

This is what I use. Works great.

Re: Air shifter
 

Rick, I think the 7AL3 will only be good for 1 shift point .
I've used the Biondo DDI-1067 on a couple of cars with 3-speeds ,it can make up to 4 shifts.

I shift by hand. There are advantages to it.

Right on!! It's called DRIVING the race car as opposed to just STEERING the race car! Jim

The Biondo deal was in the car when I got it - doesn't mean I will use it. Just curious. Thanks for the input. By the way the hood in the picture WILL NOT be on the car. I have the correct Hemi hood scoop for that year.
