I think they are talking about ALL '85-'86 32 V engines. I will check mine in the morning.

 

Mike: The issue is with the stock linkage. Since the only thing Andy changes is the second cable, it would seem inherent in the linkage, if the cables are snug, and maybe there is a reason for it.

 

Im not saying everyone elses is wrong but ...has anyone even checked for full throttle?
get a buddy in the car and have them floor it. With the foot to the floor see if you can open the linkage on the TB anymore. Or get the correct length of 2X4 and wedge it on your pedal and push it fwd...then use the electric seat adjustment to hold it there.

The only thing we did different Mike was to add the pulleys that Bill made. The angle that the cable ran other wise was too much. The pullies directed the cable at the correct/better approach to the arm on the TB....not at an angle

I couldnt understand why it didnt work either "as issued" for us. Becasue in going from stock to the SC set up you only remove a push rod that is appx 10" long...thats it. My guees is it may have to do with WHERE the whole throttle linkage assemble is mounted...it may not be in the exact same spot on the SC install compared to stock. If you change the plane or angle the cable meets the linkage you change the distance it can move it given a set arc of throw....hard to explain here but those are the gears turning in my head.

You will see that the ball cup in that picture is stock as well. In trouble shooting we actually cut the cable and used a splice. This allowed us to shorten or lengthen the cable also....it didnt work either.

If i have the relation ship correct, you can make the cable a mile long..or an inch in length, no matter what, it will only move as far as the arm on the throttle linkage takes it. In our case it was short...either at WOT or returning to idle. Although my set up is "modified" S4 TB i had to basically do the same thing as well.

Im not arguing what is right or wrong, but sharing what we found and had to do.

 

Tony:
You can add as many pulleys like mine as you want and it will not change the geometry in terms of leverage. It only changes the direction and length of the cable.

Maybe this is it....One thing that could affect leverage/travel is if the second cable's relationship to the linkage was changed so that it was being pulled at a different angle by the linkage. Say, for example, you ran the cable straight toward the passenger headlight. Moving the linkage would hardly move the cable at all.

In the case of the S4 linkage, both cables are mounted in fixed positions on the quadrant so this can't happen. How is it with the 85-6?

 

Hmm... i don't think I have much input on that issue.

I know Andy and I were obsessive about checking the throttle for proper adjustment. I know that Chris' car can fully open and fully close, as well as my car and Andy's car. Derek's car did too, but that was using whatever throttle setup came with the kit (IIRC, he upgraded to bill's?).

 

yup, i know, thats what i was implying by this i guess
... yup..adding pulleys wont matter either. clear as mud, sorry



BINGO, thats exactly what im taking about in my post here...
we have the same gears turning Bill. That area you have circled is critical because how that cable meets that linkage changes the distance it can be pulled...thus whether you get full throttle or not. Honeslty though , it looks to be in about the same postion i think as the stock location would be?

If the arc of the ball cup on the linkage was perpendicular to the cable...envision that and you get the idea...the cable wouldnt move
(crude drawing below)


The whole linkage setup works fine really...IMHO perhaps just this little adjustment ..quick check required? .
No harm no foul.

 

Yeah, Tony, you already had what I said. I jumped before I read your whole post.

BUT, let's say it is the same angle of pull as stock....at the quadrant end. And here's where I was way wrong - my pulleys CAN (actually must) affect the travel if they change the angle of pull to the throttle housing linkage, just the same as the cable pull angle at the other end. So, maybe it is my pulleys after all. Andy's arrangement pulled from the side, and a little cable movement from that angle would cause a big movement of the linkage (with lots of effort). Still, you'd think my pulleys align the cable closer to the stock alignment.

Fun and games.

 

Oh, Tony, what kind of tubing is that you used for the intake? Does it have a McMasters' part number?

 

I had all the tubing left over from my install. from woolfaircraft. The big rubber tube i got from NAPA. It only comes in 3ft sections...it wasnt cheap IRRC... like 80bucks!! I had some left over i used on Darriens.
The problem area is where the port on top of the TB cover comes off. it doesnt allow any tubing to nicely fit underneath. I took the aluminum tubing and "ovalized" it...meaning, i put it on the floor an crushed it with the palm of my hand until i got a nice shape. From there i slid it into the rubber tubing and placed a clamp on it....then did the same for the filter. Makes a really nice smooth transition to teh MAF from the filter.
Came out pretty good...then we painted it.

 

Good stuff guys! Tony, will you come and me with mine? I'll supply the beer!

 

I dunno bill, looking at the pics and from what i recall (out of town right now) your pulleys near the TB actually bring the motion of travel closer to stock. On the 86 cars the TB sits vertically and the push rod IRRC comes straight off it and out to the front.

The vertical pulley on your set up sits directly in line with the TB linkage and parralells its throw...sets it up as if it were oriented like stock using the push rod. You really cant get it any closer than you did. I dont think its an issue.

Think of the front and rear gears on a 10speed bike.....then add any number and size of pulleys touching the chain along its path( the rear derialur pulleys for example).. Theses pulleys will not change the ratio of the gear your in...they will obvioulsy change the tension in the chain, but not the ratio of movement..... you have to change gears to do that. In Darriens case we had to change "gears"..by making one arm longer so there would be more travel.

Anyway, we are pretty much beating this to death i just want to make sure folks arent being cheated out of full throttle! If your not, dont worry, obviously.

 

Its sunday, looks like youve had a few already
Your all dialed in with DRs set up. Not to worry from what i can see from the pics.

 

*hic*

 

another vegas super model. i'm tired of my shark not being boosted. i will just have to aviod tony and the gang until i get boosted.

 

Just saw the pictures Darien.....Verrrrrrry Niiiiiizzzzze.......lookin'.

You are gonna love the power.......
