However as a very basic guide, you must always run a restrictor in the compressor union of the amal of around 2.5mm (or smaller if you require increased boost).
unfortunately karl i have no idea WHY that is. and ive just been scratching my head trying to think about it. could you be so kinda to enlighten us please. as long as youre not giving out any secrets that is.
also i understand why u dont want advise on what to do on my car
so how about in general terms?
the restrictor in port C on this smal i have is TINY, about 1mm ish? ive never examined a 100% std valve so dunno if this one ive got off mike is standard or not.
also the restrictor in port R is about 3mm and looks like its been drilled
(ps im talkin diameters)
