pshhh

  1. Turbo 'Pshhh'

    Morning all, Had the LCR 3 days now and loving it more and more! I have smoothed and drilled the airbox so getting a nice 'pshh' sound however it isn't very loud. Is there anyway i can increase the noise without changing the hyperboost valve? I know the easiest way is to fit a 'dump' valve...
