no power after 3000rpm! help!! :)
Turbo Mini Forums

hi

I tried to search for issue but i can not find anything, sorry if this question is stupid but my experience with turbo engine is not more that 1 month

if car is in N gear i can reach easily 6k-7k rpm, everything sounds ok, but when i am driving i can reach only 3000rpm on tacho and car start struggle to go faster, not going at all.

I've got feeling like driving new motorbike which have restriction?!

why it could be like that?
and damp valve sometimes working and sometimes not really.

should turbo and dump vale work when car is on N gear? (at 6000rpm)

Nothing special!

carb isn't plumbed up properly, either the anti run on valve take off isn't blocked or you need to search 't piece trick'

forget to mention, that when i swap engines i have test drive for 1 day and everything was working fine, and than suddenly this happened :/

petrol pump is working, i can hear it.

could it be problems with pressure or some carburettor regulations?

oh my god.. :)
fix one thing and other stop working i love my car

Nothing special!

all pipe looks connected good, no leaking etc..
should i try to regulate (E) mixture? but should i open it or close? can'nt i make it too reach? :/

Nothing special!

thank you nick! :)

what is and where i can find this t piece trick?

thank you

hi mate..search for 'confusing running issues'..and 'bleed valve to blame?'

i think some of the info on these threads will help you out...alot of info on what to check/test and what to look out for etc..both threads were started by me , and although youve not got the exact running issues ive had the info could help

Hi Bman

yea i was reading one of yours topics, there are lot of info, but i was just wondering why it was working, and them without any modifications it stopped :/

i need to get all that gauges otherwise it is hard to see what is going on there :((

Nothing special!

i suppose there doesnt really need to be a specific reason for it to stop working, it can break at any time :) my car was working perfectly before the turbo rebuild but since being back togther ive had lots of old parts fail or break with old age.

it may just been something small like a vacuum pipe problem as i noticed a big improvment after replacing all and blanking them off properly... my fuel pressure regulator worked fine one day and broke the next so just start working your way through things and youll find the problem eventually.

just be patient with it .

yea, its true man :)

if only it would not be my every day car, i would be more relaxed in the long nights

hey
i tried regulate that mixture screw and it works much better :) but still i done fill all that power what turbo should give me :(

and now there goes oil from spark plugs :( should i close it little bit (clockwise)? :)

Thank you for help so far :)

Nothing special!

If it was running and now it's not altering the mixture is not what is required.

From your description it seems that there is fuel starvation as the boost ramps up.

Check the pipe between 'D' and 'D' above, any split in this will cause running issues. If you have had the plenum off, check that the gasket is on the right way.

I guess you run the Metro Turbo Dizzy, check the supply voltage is 12V. It is commonly wired using the ballast supply and they dont work at 9V.

it looks like everything is ok :/

yea i have electronic distributor and i change that wire to normal one so there should be 12v.

i was wondering maybe my timing is not really good?
is it was 1324 and goes anti clockwise?

Nothing special!

Firing order is 1342, is that a typo above or is that how you have it connected?

Nothing special!

Timing isn't just the order but how many degrees before top dead centre (BTDC) the spark occurs.

The only way to check this with an electronic dizzy is with a timing light shone at the marks on the pulley and marker plate on the timing chain cover.

You will neeed to buy or borrow one...

Schrödinger's cat - so which one am I ???

yea, i will need to do it, may be there is a problem :(

Nothing special!

I'm going to make a wild guess that this is caused by your actuator feed being open to air as in the second picture on this thread:

http://www.turbominis.co.uk/forums//index....p=vt&tid=352048

is it could be the reason??

i hope it is!!!! i will check it now

Thank you a lot :):):)

No. His actuator is still plumbed in on the other leg of the take off. In effect his compressor is venting to atmosphere all the time.

I don't think the open leg would vent enough charge for him not to produce boost. It would just be like having a massive bleed valve. (this is how the boost solenoid on the metro turbo works)

My money is on his fuel pressure not rising with boost.

If something is worth doing, it's worth doing half of.

without that pipe on the actuator he'll just get fuckloads of boost, thats how i killed my first ever turbo engine.

It really does sound like a carb plumbing or plenum gasket issue to me.
