This is a link to a thread, from a long time ago, over at the other place. I book marked it so I could try to learn what our by-pass system does. I thought I'd share it with the members here.
Jerry, I think I get what I was miss understanding. I should have realized that the radiator used for all C4's is matched to a standard 350 sbc w/p's gpm flow and not our Lotus spec'ed pumps. Also, I forgot that the by-pass serves to pre-heat our stats so they can open? Anyway, the stock rad can't flow what our LT5 pumps put out so they cause the coolant flow to back up. If it wasn't for the by-pass the rad would blow the side tanks off....not a pleasant thought....even if the whole rad was aluminum, if the flow allowed by the tube diameter wasn't enough there would still be a restriction and the tubes would proly blow out.
Thank you for your patience with my rather dense grey matter.
