205 TD How Much Boost?

I have a 205 TD and have purchased one of these beauties:
http://www.dawesdevices.com/powerpack.html
From my own research I have found that the standard maximum boost pressure is 0.7bar.
Bearing in mind I have No charge cooling at all what do people reckon would be a resonable Maximum boost to go for?
I was thinking of 0.9-1.0 bar. I believe standard Dturbo 306's and 405's with intercoolers run at 1.0 bar max boost.
I am a cheapskate and fuel in the uk is a rip off so I don't drive on-boost all the time.
I may in the future look at a 405 intercooler set up. But I am more tempted to try a home made water Injection system.
What do people think?

Hi,

is 0.7bar.
True.

with intercoolers run at 1.0 bar max boost.
All 405s had intercooler (whatever they ran on 1.7 or 1.9TD). I don't know
the boost pressure for XUD7TE, but 1.9 (XUD9TE) max boost is set at 950mbar
(.95bar).

 

306 boost is set to 15psi
17psi is the max i'd go for with the standard intercooler.

 

Hi Simon;

950mbar =+/-14psi so we may have the same info on it.

I wouldn't try this, I'm pretty affraid of a quick turbo wear.

 

i would have though 17 was okay as a max.
my 306 makes 15psi easily.
you are ofcourse eating into the safety margin Pug built into the system.
I hear it makes little difference anyway. Better to increase the main
fuelling and on boost fuel settings
