turbo issues

[sub555]

fitted my new turbo just took it down the road and it doent seem to be boosting properly only giving .2 bar first and second gear but the car was very low on fuel and ran out on the second run are there any things i should look for on the basic side ? apart from more fuel lol

thanks for any help

Sorry I could not answer your call mate, was out at dinner.

Sounds like the wastegate might be stuck open. If you remove the pipe to the actuator it might give a bit more but then, if it is stuck it wont make a difference. You need to have a look at the pushrod to the wastegate and see if its moving freely.

just found the pipe from the turbo to the intercooler i think has a pipe off it that runs to the dump valve has split away completely think this might be the prob?

[AlfaJack]

Almost certainly mate. When I bought my Q4 it came with a new one of those in the boot for me to fit so probably a common place to split.

[sub555]

are there any t-pieces off the shelf i can get to fit in side the boost pipe ?

[AlfaJack]

There probably is but it depends where it split.
You will need to take the pipe off and have a good look at it then search like mad on demon tweeks for something to fit

[sub555]

it has split right where the pipe runs off for the dump valve its actually the pipe for the dump valve that has come off

[AlfaJack]

Maybe a whole new hose then. I have a feeling its about ?40.

[sub555]

think i have found a place where i can get a alloy piece to fit in with a take off for the dump valve

[wrinx]

Mmm, were you getting any funny (hissing?) noises?

There's loads of places sell generic pipes and jointers but they're expensive, spending a bit of time searching will often yield results.

But usually Demon Tweeks have something, as Jack said.

well hopefully these guys can solve the problem and i could hear the turbo spinning up and when i change gear there was alot of noise but no go !!! ile post a pic when i get home of the damaged pipe !! looks like its ?16 plus postage so not to bad

[arjunior45]

the hole {oem} tube is just 16 pounds or just the 'T' piece?
waiting for the pics.

[sub555]

the ally t-piece is ?16 just got to confirm the measurements of the pipe when i get home and the dump valve pipe, looks like ile have to cut the original boost pipe and remove a section to fit this in so it fits properly. the original pipe from alfa is ?90 VAT !!!!!

[AlfaJack]

the original pipe from alfa is ?90 VAT !!!!!

Slightly more than I thought then!

[sub555]

he said i could have 10% off tho !!!!! lol

[arjunior45]

the dump valve pipe is at 25mm. The other big one I do not know.

[sub555]

well it cost 28.50 including postage which wasnt to bad including to big jubilee clips so hopefully will fit it later this week. Jack will i be ok if i send the pics to your phone as i cat upload them for some reason ?

[AlfaJack]

No worries, send them over

[arjunior45]

what about the dimension-diameter of the big bore part? Did you measure it? How much is it?

[AlfaJack]

Here is a pic that sub sent to me.

[wrinx]

Bit of bathroom sealant would see that alright

[sub555]

well alfa being alfa have made a pipe that is smaller in the middle than it is at each end !!!! 2.5 inches at each end and 2inches in the middle bloody T piece is to big !!!! so orderd a complete fitting alloy get with pipes and elbows going to change the lot !!1

[arjunior45]

I'd like to see a picture, when is finished, mostly from the part that goes to the 'end' of the oem tube {towards the inlet manifold}. That's the hardest 'curve' to follow - I believe.

[sub555]

fitted all the intercooler pipework didnt take long but now have water leaking out the back of the engine the hose on the back has been changed already. Any ideas what it could be ?

[arjunior45]

have a look at the hoses or the plastic connector for the heater.
Mine {plastic connector} was gone and I there was a leak until it cracked completely and lost all the coolant in a blink of eye.
Or the small tube from the coolant expansion tank to the 'hose on the back'. This one was also burned from the egr's tube heat.

If you had already replace the big hose {with the T - piece} I thing there are no other hoses left on the back of the engine, apart the other two mentioned above.
