Linkage for a blower

18 posts in this topic

Posted · Report post

Does anybody know to scratchbuild a linkage for the blower from the 60`s? Didn`t they use a hydraluic line or something of that sort. Any help would be great doing the REVELL KIT Mustang and would like to do it right.

John... hey are you talking about the linkage that goes to the injector hat on one side and off the K style barrel valve??. You are talking about what connects to the gas pedal right? just trying to get a better feel of what you need. I can tell you that in some instances linkages were used and in others there were cables.I can see what I can dig up I have a few books on funny cars and front engine dragsters I can see if I can find something there too.

All the blowers I've ever seen were direct mechanical linkage to the GO pedal.

Hydraulic throttle linkage was common on blower equipped engines. Eelco and Moon sold them. Also, a company called Neal Products made them. The advantage was ease of routing the flexible line in applications where a cable might have tended to bind, or where mechanical linkage was difficult. Some 'experts' complained about problems with them, but properly installed with the right fluid and bleeding procedures, they worked very well....as evidenced by their being used on Mickey Thompson's Challenger I.

The Moon slave cylinder looks like this, connected via lever to the throttle butterfly shaft in a Hilborn 2-hole injector ...

....here's a shot of the same throttle setup from the rear of the engine.....the slave cylinder and line are seen to the right and under the bolwer scoop.......

Hey John.... Here are a few pics that I found of the Hilborn injector and the linkages. I will continue to look for more. Also I will be at the NHRA races in Vegas this weekend. I am not sure if they will have any of the Cackle cars out there or not but if they do I will make sure and get some good pics of the linkages for ya. and from a couple of these pics I am posting the linkage where the throttle cable connects to, makes me think it is a cable similar to what a transmission cable is and how it operates. I will see what else I can find for you but here are a few pics......

Not 100% sure if you are referring to it, but many cars used Morse cable, it was cheaper than a hydraulc throttle. This could be duplicated in scale by telephone wire or similar single wire and thin insulation, the wire would terminate at either end with a barrel fitting. Much simpler system clamps to route the cable could be fab'ed from really thin aluminum sheet, (like maybe your favorite beverage can).
