Hi all
can any one tewll me the standard boost pressure of a p1 and what it can safly be raised to????

 

p1 boost with all standard parts wont see much above 1.1bar but full decat shd see about 1.2..as regards max boost u wldnt want to see any peaks above 1.5bar and 1.3 for the 3rd gear sprint is about right 1.3-1.4 for 4th gear and just a bit more for fifth..but to do this needs addtnl parts and ecu work to avoid bang

 

mail me if u want to look at mine paul.brian@whsmithnet.co.uk
