vibrio

see you should have bout Italian. at least you know whats going to go wrong with the suspension

higher octane is always goingt o be good for turbo cars even mroe so when you turn thee boost up. It's only just got here in Glasgow. From using shell SUL can can clearly say that it feels better top end but does it actually make a difference. who knows. I always fill up with shell super in both my puntos and now they have optiplop I will use that.

teh peirburg valve does not spin the turbo up quickley and is not adjustable. bleed makes the car more drivable.

that looks strangly like the set up I used

Right. my GT had (he he he) an electronic boost controller to adjust boost (0.8 bar actuator).I replaced it with the bleed valve. http://upload.turbosport.co.uk/gallery5/20026121440624340.jpg It had three pipes going into it. one from the actuator (pipe coming down from top), one that goes into the inlet track (the one on the left) just behind the AFM and the other pipe comes from the turbo (the one you can't see). witht he valve fully unscrewed max boost is 13psi against 15psi normal. then you screw it is bit by bit tell you get the boost you want (18psi). you can get two way bleed valves as well. this is what a superchip dealer will fit when you get a superchip on the GT. the hose that goes to the inlet track is blocked. if you fit a two way bleed on the actuator pipe then you should be able to control boost http://upload.turbosport.co.uk/gallery5/200262235934584392.jpg

I just fitted one to my GT. does seem to make a differance. not sure how well the jet works when your travelling at 100mph. My wipers don't go when I use the jets which is nice
