    Jet Boats
    Hi there, I am running 2x 600DP Holley blower carbs on top of 671 blower. Question I have is, is it normal to see some fuel coming down the boost reference lines? When I pull the lines off down at the tee where the boost gauge is hooked into as well on back of manifold, some fuel runs out the...
  2. Need to Boost Reference Dominators

    GN7 On the Dyno
    Does anyone know of a carb shop in Ventura County, CA or the San Fernando Valley, CA that can do this? Have two 1050 Dominators on a 540 with 8/71. I know that Performance Carb and Speed in Ontario, CA can do it, but I was wondering if there was a shop closer to where I live in Ventura. I'm...

  6. Boost Type Power Adders

    GN7 On the Dyno
    I am starting a twin turbo SBC project and did a quick search for example 383 SBC twin turbo dyno charts. Stumbled across this. I thought it was interesting the differences in power curves. HP in relation to torque. NO it was not an apples to apples comparison. I wonder if someone has a N2...

  12. boost gauge fluttering

    GN7 On the Dyno
    Anyone know what would make the boost gauge flutter? Only does it in boost, not vacuum, and gets worse as pressure goes up. Needle had always been stable at any pressure. Compression is good, all cylinders within 1 to 2 lbs.

  14. Horsepower Vs. Blower boost.

    GN7 On the Dyno
    Is there a correlation of how blower boost affects horsepower? As an example, if an engine makes 1000 horsepower while producing 9 lb. of boost, what should that same engine produce if the boost is increased to 11 lb. of boost with no other changes? Is there a predictable correlation of...

    GN7 On the Dyno
    Been working on a 73 Hallet 21ft DC. Went out for first run this weekend and when the boat hit 3,000 and 10lbs it just shut off. I believe this to be a problem with the pressure restriction parts in the inter cooler Sorry I don't know what they are called. Anyway, there are two 1/4 in ports...
