Default Throttle Cable

I was reading the interesting if not cryptic post on the "Turbo Zet" and was wondering if you could possibly get the same effect by adjusting your throttle cable. Is there any way to tune it so that you get better response?

If you're talking about what I think you're talking about, the answer is probably no--don't you think that if there were some magic that could be worked by jiggling the throttle cable that car manufacturers would have done it?

But if you'd care to expand on your thoughts, please feel free. wink

I counter that with a solid MABY

I will be cheking when I get home tonight. It seems to me that my Throttle cable is not as tight as it could be.

I want to check to see if I really am going 100%WOT.

IF not I will be adjusting it..

Ill post tommorow with What I find..

just wait till you start fiddling with it and your car is idling at 2k

You really shouldn't go messing with some things.
I noticed another popular low-cost mod is to remove your butterfly...people, STOP!!

Some things are there to ensure smooth operation of your systems.

WeaponR sold a "throttle rotor" a while back that basically opened the throttle quicker. Instead of a circular "roller" for the throttle cable to pull, it was flat on one side and a bit oval. the net effect was that instead of the throttle plate opening nice and linear (foot off pedal = closed, pedal to the floor = open), now it would be fully open at 80%.

Complete bunk, if you ask me. But it's one of those things that if you put on, it seems like you're going faster because you have a bit more pull with less pedal movement. Problem is, the gains are all in your head.

You will get better throttle response by properly tensioning the cable, but beware: too tense and the plate will stay open a bit, which will allow too much air at idle, which can be rough (it upsets the vacuum, fuel flow, etc). I've done this before by accident. You just barely want all the slack taken up.

good luck,
ac

THat I know.. But On my tibby you can see the slak in the Throttle line.. Its actually sagging a little.

I have a feeling that its happen during break in.. THe cable isent streched before hand.

And before people go OF about it being a steel line and they don't flex. BULL. I have seen steel cable flex severaltimes. (even seen it break under strain and that is scary)

AND I did not say I was adjusting the plate. I said I was going to see if it goes WOT 100%. Ill take a look and see if taking up the slack see what happens..

DID I SAY THIS WAS A LOW COAST MOD.. No This is an adjustment to something that should not have to be adjusted but may have to be..

Before you bash about anything (even if you have a performance shop which given my local experence means CRAP to me) Read and think.. Don't Knee jerk.

Yes, of course you should adjust your throttle cable to eliminate the slack. But be careful--I actually had my TB off last night and this morning I was idling between 1500-2100rpms with it bouncing a bit because I wasn't careful not to over-tighten it. I just stuck the peg back in, felt the wire and it didn't feel too tight--I actually thought about tightening it. But the slightest bit of tension can pull it open a crack.

As Curtas mentioned, the current armature or 'throttle rotor' is designed with the curve to give a fairly linear opening rate. And yes, by changing the shape of it you can change the opening rate. But as he also said the effect is purely psychological...sure it revs more when you touch the gas. But you've lost precision of control because of that--at low throttle it will tend to over-respond to accelerator movements. Face it--if you can't stomp your foot down in a tiny fraction of a second, you shouldn't be driving let alone racing. Your reflexes are too slow.

Unfortunately, you can't adjust the max opening using only the cable. Because it always travels a fixed distance, the optimal stop point is the one that provides the proper idle without any cable slack. To get it farther open you have to increase the travel at the pedal, or decrease the travel rate required by the throttle rotor. The fact also remains that there isn't much difference in flow between 90-100% open either. It helps a bit but not much--not as much as a larger throttle body would.

Unfortunatly the word on the BBTB for the 2k3's is Not much yet..

Had it looked at and even poseted pics.. The walls are very thing combined with the Idel bypas setup it make a bore job VERY tricky if not almost impossible without adding metal..

So FOR a BBTB its on standby.. THE IM has plenty to go but without the TB it won't make much difference.

not to change topic or anything

it was stated that taking the butterfly out is a bad idea?

i know on celicas its dyno proven to add 1/2 hp and like 2lbs of torque or something i got the dyno somewhere in this computer

i know one affect is that when starting the car, it wont start up as quickly but what are the other bad affectS?
