Steve W2 Posted May 5, 2004 Share Posted May 5, 2004 There is 14.7 psi in 1 Bar so: standard boost is 0.8 - 0.9 Bar *I think* (reasonably sure) = 11.76 - 13.23psi Max recommended boost on standard set up is 1.2 bar = 17.64psi Fuel cut is at about 1 bar (seems to vary) = 14.7 psi So you will also need a FCD (fuel cut defender) TRL do the best ones as the limit is adjustable, it doesn't just remove the fuel cut limit out all together.

Speak to Chris Wilson about a restrictor ring, he makes them to order for about £20. You will need to tell him what pressure you are hitting max, for him to able to calculate the correct size orifice. You will also need to let him know what pressure you want to run max, i.e, 1.2 Bar or 1.1 Bar. If you haven't alreday guessed that means you will need a pressure gauge fitted, look at the ENVY site for these. I'm pretty sure Gaz doesn't like playing with rings so its definetly CW you will have to speak to:D Quote Link to comment Share on other sites More sharing options...
