Biz said:The engines (1.3 and 1.4) were both designed to run 1.0Bar (14.7 Psi) but were turned down to 0.75 (Hence the 0.75BAR overboost switch) due to the press crashing them when launched!
or so i heard anyway!
jamie86 said:If it's a MK2 just disconnect the overboost sensor located at the top left hand side of the engine it's just two wires tape them up and away you go.. :devil:
EDIT: Just read it's a MK1 not sure if they are the same
SteveNZ said:Yeah they use the same system
oh dearMuzzie said:Where do you put a boost tap on a Mrk1 UT?
I wanna wind the boost up a bit on my UT but only now and then for a little fun, but leave it down low or perhaps practically off boost for daily driving.

fueling needs sorting or you will either under fuel or overfuel which is not good for the health of the engine
and thats only to 1.0 bar. after that the head gasket will not tolerate high boost long. it needs modifying

I turned up the boost on my Mk1 some time ago, it runs absolutely great at 1bar. Steve is right of course, the ECU is mapped that far (take a look at the graphs in a Haynes Uno manual). I'm not sure what is happening beyond 1 bar, though.
I think if increasing the boost, the recirculating air valve become crucial - if it leaks, you lose some of the 'extra'. Also, cleaning my intercooler seems to have made a difference - probably in the re-tightening of the various hose connections. I'm going to try water-spray on the intercooler next.

Dunc Uno Turbo said:a standard uno turbo will run 1 barno problem. the ecu on uno turbos is a very clever bit of kit and will actually adjust the fuelling itself when the boost is raised. but....it will only adjust it to an extent, after 1bar of boost, u will have to adjust the fueling by another means, like FSE fuel regulator, bigger injectors etc
