    Default Wast gate

    Just a thought
    My mates truck has the wast gate permanently shut for extra boost.
    Is this a possible mod?

    Mmm, me thinks this would be slightly silly. The waste gate is there to stop the boost from getting too high.
    In the 'old' days you could put a bleed valve in to stop the waste gate from opening too soon, a very primative way of increasing boost but keeping it permanently shut could cause serious damage to your engine.
    I may be wrong but thats my honest opinion.

    Thanks Lee.

    Was talking to him today & he says the head bolts are only good for 15psi boost , so apparently he limited fuel pressure for a maximum of 15psi boost , 20 psi is attainable but as you say could cause some issues , he backs off the throttle when EGTs reach 1200* , says he does'nt wanna hole the pistons.
