    Twin 45’s balance

    This must be a common question, however I am looking for a solution.
    How do you use a Syncrometer on a Pinto running twin 45’s and long trumpets in a mk1 Escort, the inner wing prevents access. I have the long rubber 90* adaptor but this does not help. Is there an easy solution to balancing these. Any help/ ideas on how to resolve this appreciated.

    Thanks
    Mark

    For balancing purposes, whether the ram pipes are there or not isn't critical. Alternate method is add some barbed spigots in the inlet runners and use m/cycle vacuum gauges - a rack of 4 makes balancing a doddle.

    I used the same. Pretty easy to do and you do notice the engine running improves so you know you are going the right way.

    Fit short trumpets that allow installing the meter. If that’s not an option.... remove trumpets

    Daft question really, but I presume when doing this all you're trying to do is match the vacuum between cylinder runners? I've got a set a vacuum gauges somewhere.
