same stuff mate, down about 10-20kw's feels a little sluggish, blowing a bit of black smoke and using bit more fuel than it should
boost gauge is going all the right things, 7-9psi on the SC then up to about 14 on the turbo ,just not much oomph to go with it
anyways, got a day to check it over again so less typing more spanner swinging!

Black smoke is unburnt fuel in the exhaust so it could be over fueling although they do spit a bit out when given it some boot.
S/c boost should be around the as the turbo.My gauge is in bar on the boost controller and it reads 0.85-0.9bar (1bar=14.7psi)
So there's a start,could be the vaccum hose you used to replace the originals
should be 4mm and there a resrictor is one of the 4mm pipes to stabalize the boost while the s/c going.stick a 4mm vaccum pipe on the actuator pipe and you'll see what I mean,you probably see 5-7psi on the turbo then.the smaller the pipe the less boost same goes for the s/c. And the ignition timing who set this for you and how was it done??
Honestly looking for problems with the ecu is'nt the answer I've been through all of this before and you always get some ####er saying check the engines brain.No point

thanks for the info! the vac hose i've replaced the stock stuff with (which didn't look stock, but it WAS old) is silicone and only a tenth of a MM off 4mm which was the closes i could get at all the shops as they all sell in imperial measurements no metric...
ignition timing is as i got it, but i don't think its right... as when i got it it was running even ####ter than now!
i've kept all the hoses but don't know 100% which ones which
which line has a restrictor in it? JUST the one between the turbo outlet and its actuator?

the one with the restrictor in it is in the diagram I posted the yellow pipe exactly where the number 5 is
Here
OP
OP
will print it out and check it now....
then later...
I put the restrictor back in the yellow line, didn't notice much difference
still only getting 5psi on the supercharger at any throttle below 4krpm
also where the first white vac line is (number 1) for some reason it was reversed on the solenoid (number 22) from where it should be in the diagram
i put it right as in the diagram but now no boost at all on the supercharger (can hear it spinning but no boost) strange!
are there any other restrictors i should be wary of while replaceing some of these crusy hoses?
okay so if i drive it around the way i got it, with the white and blue lines reversed on solenoid 22 then i get my 5psi on the supercharger, and 13 on the turbo as its been doing so far
if i put them the way they should be, i get a stack of noise from the SC but no GO GO so i can only assume the bypass is open
if any of you boys have any other hints for me i'd love to hear them!
hey barry on the valve that you send me, do you know what colour hose goes where on it? if thats backwards in both spots it might help know what i mean?
is it blue line to the bent connection on the side or top? cheers guys
im gonna fix this!!!!
its beaten two owners before me but im gonna fix it...
is anyone able to tell me where hose 14 is supposed to end up?? it just falls off the bottom of the diagram... same with 11,12 13 & 14...
i think this might be where my problems are, i have a feeling its backwards going onto the solenoid from the butterfly valve that controls the bypass
would i be right in saying that 14 (red hose) dumps into the intake POST turbo, and yellow feeds into the pipe coming from the intercooler?
everything else is as it should be from what i can tell on the diagram
so really, if someone can tell me the location of where hose 13 and 14 are supposed to go i think i've got it right....
update...
RIGHT digging digging....
so i found a little faded yellow mark on the pipe that connects to the turbo, someone had marked the RED hose with a marking the same as one on that fitting so it seems the hoses were backwards!
i can only assume the red hose plugs up under the intercooler to intake pipe
good news is i think i've got ALL my turbo power, it pulls hard once it spools up
BUT, if you read above with my initial problem of the white and hose on solenoid 22 being backwards, i've still got that same problem... that is, lots of supercharger noise but no actual boost being seen at the intake
any ideas what this could be??
i think im getting close!
is there any particular line i could plug my boost gauge into that would tell me how much boost the supercharger is actually making?? this might give a clue as to its condition
