Vic, You mentioned a "positive/push morse cable" on the throttle. I was told that it was better for reaction times to have a pull cable on the throttle.
Is there some new thinking on this?

[SLICK VIC]

I dont know about the new thinking but,
this is a new car for dave and his old chassis the
cable use to come back torwards the seat and loop
back around to the pedal and when you pushed the pedal
it would pull the cable, now the cable is fixed in a mount
just below and in front of the pedal and when you push the
pedal down it also pushes the cable, and also the way it
attaches to the linkage on the throttle shaft it too pushes up
to open the blades as opposed to pulling downward.
im confused now are you....
this is just the way the pedal is set up.

Thanks Vic. The info that I had came indirectly from Fred Mandoline. I was told that there is a bit of flex in the cables when they are pushed and it affects the reaction time a slight amount. Of course, when measuring things in hundreths of a second, a slight amount can make a big difference.
This was several years ago and maybe there have been improvements in the cables since then. That's why I asked the question.

Rock, it may not be right, but the one on our dragster pushes also, it feels ok. It's a new morse.

Lippy, It will work well either in a push or pull setup. I had mine set up to push for several years and a few diiferent people told me it would be better for reaction times if it was in a pull configuration. Being an old fat and lazy fart, I need all the help I can get in the reaction time department.
I have changed mine to a pull situation but don't have any decent runs yet to see if there is a difference.

There's a discussion about reaction times and such over at Deepstage.net with Jeff Arend giving input. I just asked him about the push/pull cable.

Rocky,

On my 23T car it is a pusher. On the new Coupe, it is a puller. It really just depends on whether the cable attaches to the heel side of the pedal or the toe side.

I never had a problem with the push, but some smart guys pointed out, that if the cable has any weak spots, or isn't braced properly, it will bow out and not push the blades open. Or, not open the throttle all the way causing you to lose the race.

Think,,,pushing a string,,,vs pulling a string,,,which would you rather try?

Just an opinion.

this is a very interesting topic... on my old heap the linkage off the pedal was all mechanical/bellcrank stuff....

[Solid Rock]

Your making good points Rapid.
When I originally set my car up several years ago I made it a push system because it was easier AND I just happened to have a cable in stock that would work. LOL
Since I was told about the difference I would look at the pro cars at the track and I never did see a push cable on any that I saw.
Many of them had the cable that came back and looped around from the rear and attached to the pedal, enabling the pedal to pull on the cable.
It seems to me that the pros would not have the extra weight of the longer cable if there wasn't a good reason to have it that way.I realize the the extra weight is but several ounces but those guys are extremely weight conscious. They also only have about one inch of movement to wide open throttle.

Here are some pictures from the 1990`s when
Tyler Taba owened the Qaurter Bender funny car in Hawaii.
Mild bbc 454 running super pro i believe.
check out the radiator,..cool. oh and the pink chassis.
