Idle speed solenoid

(1/1)

Turbo26T:
My project car will have A/C.. Im looking for an idle-speed solenoid for my Quadrajet with enough force to open the throttle at idle when the compressor comes on .Factory Q/Jet idle stop solenoids only extend after the throttle is opened and do not have enough force . This would lead to stalling unless you blip the throttle.
Any thoughts , real world examples ,SWAG's etc..
 Thanks ,
 Stan

Kenth:
It would help knowing the carb-# and application.

Turbo26T:
Kenth : Its a #17082224 ..but I've tried factory Q/Jet idle-stop/idle-speed  solenoids and they are not strong enough to open the throttle from curb idle . ..Only after the throttle is opened , will  the factory solenoid extend and hold  idle speed at an increased RPM. As I understand it , they were used to retract after the ign is turned off to completely close the throttle plates to negate "Dieseling"
 What I'm looking for is a solenoid that has enough force to increase idle speed when the A/C compressor comes on without having to blip the throttle pedal...Either a vacuum or an electric (12V) solenoid can be made to work..
 Hopefully this may clarify what I'm trying to accomplish..

Kenth:
Normally, the idle speed is set with the solenoid active, A/T gear engaged and AC on.
No further increase in speed for AC on should be necessary.
With the solenoid inactive, the speed is set 100-150 rpm lower.

Turbo26T:
Kenth : Thanks for your input...I , however , am well versed in solenoid operation in regards to throtte speed increase ..No offense intended ,  but Im not wanting to know how they operate , setting procedure , wiring diagrams , etc
 I am simply looking for a solenoid strong enough to open the throtte against the return spring pressure and increase the RPM's when the A/T is in gear , when the A/C compressor comes on @ Idle....
 Thanks again for your input
