WAW so Kool man, but now i have a question not just for you, for everybody who knows about this cars, i had a discussion with a friend about this engine, on this particular era, he insist that they didn't use retraction spring and because i follow the reference pictures i told him that i saw most of the clear pictures with that, so...
It was something that they didn't use a lot or in all the cars, or that was something change along the way?

Gentle men, thank you for the kind words!! Marcos? If your talking about the throttle return spring. A lot of racers back in the day went to a hydraulic throttle actuator, due to packaging constraints and limited space for routing all that linkage from the loud pedal. But, if I remember correctly...NHRA rules state that the throttle lever/linkage MUST have a return spring as a safety component. Perhaps some hydraulic set ups didn't have one/need one. I never raced at that level so cant testify directly to the fact but...My knowledge and experience as an auto mechanic tells me that there is a throttle return spring in the system somewhere. Be it on the pedal/actuator/levers or a clock spring in a throttle shaft operated Barrel valve. There is a return spring in the system...

As an aside here...A throttle return spring adds more visual impact to a build soo, why leave it out??

The hydraulic throttles (at least the ones I ran) had an internal spring to push the plunger back AND a return spring on the butterfly shaft to pull the throttle plates and the barrel valve closed if there was a failure anywhere in the throttle linkage clutch / engine explosion or driver issue to prevent a runaway.Rules also required a foot loop on the throttle pedal of which one purpose was the be able the physically pull the throttle closed.
Side note is the Hydraulic throttle aside from an easy install had less points subject to binding and failure.

WAW thanks for this amazing info Pete, definitely will look more into those rules to see, or maybe some old reference pictures for more clarity, much appreciated |
