    Default High ratio rockers low end power???

    Hi guys, just a quick one.

    I have read through all the threads about the fit high ratio rockers and how much better they are over the stock rockers, especially high end.

    However i am looking for some extra grunt down low, not so much top end. I already have pacies and 2 and a half inch exhaust and k & n filter. Does anyone with a vx who has the high ratio rockers have any thoughts on the down low power increase??? is it noticable??

    Also would anyone recommend getting stronger valve springs as part of this process??? is it expensive to replace them aswell???

    Thnx muchly

    (ps mines a manual so i don't know if that makes any difference??)

    As far as I know the only way you are going to increase power down low with your set up is to stroke it. The extractors and exhaust system increase the top end but rob your bottom end. Rockers will only increase your top as well as they increase your intake capacity. You could try upgrading leads and spark plugs but probably wouldnt be noticeable. Also a tune may help but again the increase may not justify the cost.
