    300x manifold issue

    I notice that my ski won't pass 5 pounds of boost and 5K rpm I did also notice a weird noise in the engine bay, not knocking or anything I then got home and noticed when I accelerate the intake manifold gets inflated like a ballon under boost. Are the suppose to get inflated under boost or did my intake mmanifold just took a shit on me?

    they are plastic and yes they inflate like a balloon, however if you canyt obtain anymore than 5000rpm you have a problem have you checked all boost hose clamps and listened for any airleaks. im guessing thats the noise you are hearing

    Indeed that noise must be a boost leak then I'd have to see where it is then
