Why does my T34 .63 not turn when idleing?

The car sounds like a normal car on idle aswell

 

They don't necessarily, increase the revs slightly and it should...

Martin

 

It will with a little rev But y would it sound like a non turbo from behind on idle

 

Don't understand what you define by "non turbo", they don't have a unique sound really.

Martin

 

Ok its not bubbly like a cossie its more a constant drone sound like a boyed up corsa sort of thing lol

 

Oh see what you mean, tbh I always found they sound like Pintos, on which they are based, if it's not broke don't fix it

Martin

 

it kinda is tho lol not alot of boost stage 3 tho

 

What is the pressure?

Martin

 

under a bar dont even notice the boost

how it should idle

 

this 1 sounds a lil different

No where near stage 3 at a bar that's for sure, weak actuator possibly.

 

I dont know but need to sort it asap

 

Could also be a big air leak, but u would be taking it to a well known tuberculosis and get it setup

 

Tuner I ment Fucking phone

 

Exhaust has a big part in the sound aswell

 

Its going to the tuner by castle coombe

Mat it has a 3" scorpion with a 4" rolled out pipe

Going to check for air leaks later aswell

 

If it's under a BAR you have something wrong, is your Amal valve working?

Martin

 

It clicks thats all I know then

 

Mine used to have a scorpion and it never had a burble noise but it has the mongoose on it now and sounds much better with a bit of burble.

 

If it's clicking that is wrong, it should CLICK when the ignition is switched on (And so has power applied), clicking means it's being told to do so, i.e. bad TPS calibration, if not possibly a faulty valve.

Martin

 

Thats what I mean it clicks with ign on and if I unplug it and plug it in etc as it should

 

So it clicks and if you disconnect/connect the plug it doesn't click? First thing to do if verify it has a good power supply, WITH the engine running, could be a wiring problem.

Martin

 

No it clicks like normal If I unplug it clicks if I plug in it clicks

 

Oh I see so that seems to be working then, I thought you meant it was constantly clicking, maybe you have a boost leak/faulty actuator etc then...

Martin

 

sorry mate

 

i am going to check for air leaks later

 

Defo no air leaks and it idles loike a cossie now I turned the idle down to 850 was on 900-950 now it sounds good

Still need to sort the boost out tho

 

The turbo should spin on idle

All mine have

Steve

 

have you dropped off the exhaust from the back of the turbo and had a look? Sounds like you may have lost a blade

 

Its a new turbo mate and yeah I have looked at the blades and they all seem fine

The turbo spins at about 1k or with a quick poke on the throttle

 

maybe a faulty turbo bud it happens as steve said and i would have thought myself all turbos should spin at idle as all mine have

 

may be a bit tight after rebuild ,what does it fill like with your hand

 

i bet its a 2wd manifold? they dont spin sometimes if the idle is low enouph,hence the non existant burble noise, this is normal,no faults here, just change of adjust the actuator to get the boostup.,and if you want it to spin on idle, raise the idle speed!

 

There is NO fault, mine does not spin on idle.

Martin

 

Cheers guys

It is a 2wd manifold I have spoke toa tuner and he said the same some times they dont spin

So all looks good I pos need a actuator tho

 

Wilky the turbo spins easy enough by hand maybe a lil bit tighter than normal but there is no tight spots its the same all around

 

Martin can you post a vid up of yours on idle from behind please

Any 1 know why the shaft wont spin and how to get the noise back
