boring I know, but anyone clarify the stock boost level of a MY01?
mines producing about 0.75 bar(10psi) according the the gauge since fitting and removing 'the' infamous DAWES...

thanx in advance

feathers

Mine read 1.1 bar . Never been modified.

RT

Hmm, the std 220hp rex gives 1.1bar?
The STI spikes higher, but more or less holds 1.05-1.15bar also, depending on gear.

Mash

thanx for the info feathers/RT, look's like I am down on boost and I need to investigate further....

martin, YHM.
sound like you put the turbo body to actuator plumbing back on the wrong way round- the bent bit goes to the actuator (to the left of the t-piece) thus the restrictor is in the wrong place.

and don't remove the DAWES again!!!

Mash

Simon, apologies for breaking ranks! I consider myself suitably chastised for committing such a heinous act........

NB, cheers for the email, I responded before reading your note about the restrictor. Will check it out in a min, once I have done me choirs....

Simon - forgot to ask, what was the stock boost on your MY01?

slippyr4

My MY01 was 14 Psi peak, 12 held.

Now I have the PPP it's about 17 peak 14 held.

RT

Mash, was your T piece with the restrictor the right way round?

0.75bar is waaay too low! Seems like the std should be hovering around the 1bar mark.

Mash

thanx slippyr4/RT for the info..... did'nt get a chance to check the t-piece last night and the wife has the car today, however when I get home I shall check it out.....

RRH

martin,
7ish in 1st, the circa 13.5 held through all the other gears.

Unless you've missed the restrictor off, it's much more likely that your gauge is knacked than anything else.

Does it feel underpowered? that much diff would be very noticeable.

Mash

thanx all for your input so far..

Q, which side does the restrictor go - actuator or turbo output side ? It's currently on the turbo output side in the shorter peice of tubing. If it is the wrong way round, then it's been fitted wrong from new!

Q, Also what does it do ? does it dampen the boost spikes or something as the car definitely has a 'pulsing' sensation (not misefire) under WOT, I wonder if the wastegate is hunting or something due to the restrictor being in the wrong side?

Any clues much appreciated...

RRH

see original mail.
restrictor goes on the actuator side

Simon, tried it on the wastegate actuator side and it felt slightly slower! also the pipes just dont look right that way round, the longer one with a bend in it seems to naturally go on the actuator with the smaller straight one(with the restrictor) going to the turbo output. I'm confused now...
