    whats the kind of performance i could expect with the pipercross viper kit straped to a 98 VTR grey rocker cover i think??

    in the demon tweeks catalouge they say you get up to 10bhp extra but i dont think you would get that much
  3. #3
    your probably looking at 5bhp if that

    Save some coin go for a raid hp max flow carbon fibre one it reatils at around £90-100 and is pretty much a similar set up too, you can get them online or from ebay

    what about a bmc,they are cheaper and just as good
  6. #6
    maybe 3 bhp

    with cold air feed 5-6bhp tops, without 2-3bhp @ a guess!

    if u want better performance, throttle response just get a k&n replacement panel filter.

    £45 cant go wrong!

    if u want induction noise then kits are better
