    quiet polybush???

    after a run in t5pete,s car yesterday i found out my new top mount polybush is too quiet.
    his sounds like its running filterless throttle-bodies and no bonnet but mine is far too tame compared.
    it is fitted correctly and everythings fully tightend up so whats gone wrong, any ideas?

    The only other mount i would have thought that would come into consideration is the firewall mount but most people i have spoken to have the same results as me when fitting the poly bush

    do you mean a standered paper filter in the air box?

    as when i changed my mount to a powerflex i changed my air filter to a K&N panel filter at the same time. so im not sure if it was the polly mount or the filter that made the diferance in sound or a mixture of both.

    The K&N panel filter doesn't really make to much of a difference in noise output from the exhaust (not on mine anyway). Stainsey I think the drilled airbox may make a difference in noise but it can be a bit of a performance restriction sucking lots of hot air in from the engine bay.

    im realy happy with my engine sound. its realy throaty and beefy sounding since i put the polly bush on. not a fan of drilling holes in things just for a a better sound. the car sounds good as it is. dont understand why people would wona reduce good air for the sake of a sound

    polly bush in the top engine mount we are talking about.

    if you look just above the yellow boost pipe on my engine you will see the purple polly bush we are talking about mate
