Throttle body 100% open HOW-TO

im thinking the cable is too tight...however its opening about 90% this time so im not really that bothered...must not have been pushing the accelerator in the whole way before.

 

ahh yup i read the post.... ill look for a post about those kickdown cables mate...then ill look into buying a new exhaust set up....can i do extractors first and then the other stuff later? as i can see some vn v6 auto pacemaker extractors in the paper, new and never fitted 350 bucks....is that a good buy?

 

im a happy chappy!

while replacing the coolant sensor in the engine bay today, i thought id have a look at the throttle body to see how much it was opening at full acceleration.

Surprise, surprise, was only opening to about 70 - 80%, the little tab thingy wasn't the problem with mine, it was the accelerator cable was way too loose. It was REALLY easy to adjust....(just fiddled with the two nuts each side of the bracket)

will take the car out for a test drive tonight.

 

hey greenfoam,

im not sure if i have extractors....i presume that those parts with the weird "white mud" on them are where the extractors would be as it looks like thats where the exhaust goes up to the engine...im presuming its just an ordinary part of a VN and not a performance part.

 

hi

have a look at some of the niffty things these VL turbo guys are doing you may get some idaes from them

its real good work maybe ask arund there about turbo headers to suit a vn V6

here are the links

In answer to this NO NO NO, only VL's had coolant being routed through the throttle body.

 

i've redisgned the bell mouth will post pics in correct post, but I am putting in tomorrow, I will check the throttle body then too, I have to TB's here 1 a VN and 1 a VQ will compare and post differences. Am about to go searching for that kickdown cable adjustment post now

 

What are you doing with the bellmouth?

 

I have put it in the car today and tested it and by jesus, what a weapon. I also grinded back that stopper I wasn't getting 100% either. I have a broken throttle cable right now so I repaired and got the other half to sit in the car a push the pedal down once everything was reassembled to see what was going on. Ok using your hand you can open the butterfly 100% after grinding the stop tab. but the cable will not open it that far, at least mine wasn't even after adjusting it. So using the throttle cable mounting bracket of the spare motor I grinded of the piece I needed and mounted it at a different angle. I now get 100% thottle via the pedal also. the bellmouth I cut 75% of the top leaving just the bottom 25% there then opened up the mouth of it to flow the same as not having one the, but here's the thing the car goes better than it ever has, and idles almost perfectly. the airflow gauge is signalling that on full throttle it run a much richer mixer now too as before the TPS sensor wasn't being opened 100% either. I will test tomorrow on the way to work, with fuel economy etc. and will post pics of bell mouth mod and throttle cable mounting bracket mod, during the week when I get batteries for the camera

 

wow, fuel economy was up during normal driving, but not suprisingly I used more than normal testing the thing. the accelerator pedal response is a lot higher now, will take some getting used too. the car did not stall once today and provided a steady idle at 800rpm.

there is not as much idle suction noise from the airfilter now with the bellmouth re-installed, but I have a modified IAC valve with 2 thou taken of one edge to allow more air in at idle, and give greater suction. however it raises the idle RPM and using the base idle screw you can adjust but bring it out to much and the butterfly developes a slight stickiness.

I have welded on the new throttle cable bracket. all that is left to do is paint the bracket fore aesthetics looks, and remove the bell mouth and tidy up the mouth of it a little more then I will post pics.

I will change IAC valve tomorrow to give it more of a suction sound, and will see how well it idles.

I mean going good is one thing but stalling an auto in front of people is just plain embarasing.

 

if anyone needs a manifold made up for a turbo on their v6, drop me a message. $700 bolted on if turbo and cooler supplied.

 

hey i got a question if you grind the stopper too much is there anydanger of the butterfly opening too far so instead of making it 100% open you go too far and its 110% ? or this cant happen?? mine only opens around 85% so i was gonna do the mod this arvo for something to do

 

mine opened all the way havnt looked at the ss(got a vn ss and vn spac), yet but i got an idea for ya's get some carby/throttly body cleaner ! urs are all black of oil, i cleaned mine and now its all clean again!

 

you can get a turbo manifold off F.I.T

 

sorry if this thread is a bit old,
ive read through the whole lot an i dont understand what you have to grind? an if the thing that is going to get grinded of stop it oppening past 100% what happens if it does go past that? does it start to close again?
thanks
