BHP Gains?

  1. #1
    I have got a MK2 VTR and at the moment i have got a:

    Magnex full s/s system
    GMC 4-1 Manifold
    Pipecross open foam filter

    Any guesses on what BHP my car will be running with these mods? I know the open filter will loose some power also!

    Although I will be changing my air filter soon for an enclosed one and then get some cams and a remap! So will be running:

    Magnex full s/s system
    GMC 4-1 Manifold
    Raceland enclosed filter
    Cams and remap

    What will be the BHP with these mods? Will I see somewhere near 120BHP?

    I'd say at the moment without a performance cam you are producing 105-110bhp..

    Is that with the open filter? If so, will there be much increase when I change it for an enclosed one?

    Yeah thats as you are now, as the exhaust with the manifold should see you near enough 10bhp anyway..

    Yeah you will notice a difference with an enclosed but your probs not going to gain an awful lot over a standard airbox with a green panel filter in..

    I have found a Green cotton enclosed induction kit on the GSM motorsport website, so might go for that one!

    yeah sounds good, green cotton are really good imo. With that your looking at a safe 110bhp providing your engine is healthy etc obviously.

    with an enclosed id say 105 - 108 mate cam kit would see it be beating a standard VTS

    How much then for cams and remap?

    cam kit id say around 200 - 300 remap is quite a bit say 400 maybe more

    easily £700 for a cam and re-map, and that will see you over 120bhp depending on how wild you go with your cam, atm that open filter is letting you down mate!
