    Default First outing of the season

    It went... well so so.

    It's a SBC,177 Blower, dual Carter's(400 CFM) running .395 jets. timing 6* static 30 Total. I noticed when coming up on boost fuel pressure drops from 6 to 3, engine starves and develops a "Lean Pop" Plugs don't look the greatest. Is the engine running the carbs dry? Fuel pump can't keep up? It's a Holley Electric Blue (110GPH) Also the fuel pressure seems to bounce somewhat 5.7-6.0 would a regulator with a return line fix this? I am thinking of going mechanical on the fuel pump.

    On a side note, after a run the carbs and carb adapter have frost on them and are cold to the touch. good?

    a suggestion, if i might...take those Carters off & put a single Holley 750/800cfm DP mech sec on it! ...it will run awhole lot better & you will be alot happier!...also...the Edelbrock or Carter HP mechanical fuel pump is a good choice...on your side note...my blown alcohol SBC would ice/frost the hat after a run (Dragster), so, i dont think you have anything to worry about ...this is just my .02 cents of what i would do

    I've been down this road. My solution would have been a Clay Smith fuel pump and a Endely check valve set up at 7 lbs on the end of a fuel log returned to the Y if you have 2 fuel tanks.

    One thing that I had wrong with my blower set up was my J tubes in my fuel tanks. They were 1/4" ID. I made new ones that added .125 / 1/8" making them 3/8" Added a Aeromotive 1000 electric pump and called it a day. Wasn't cheap but neither was my motor.

    If you could spring for a Clay Smith Mechanical and a decent Return type regulator and return to your y, You may be set. Save the holly for your nitrous

    Jus Kidding, toss the Holly..

    As I remember, Carter's were essentially a vacuum secondary carb and it probably has the same shortcomings in a boost situation. I don't even know HOW you would boost reference one. So as you come onto boost, would the carbs see greater vacuum shutting down the secondaries that started to open under low vacuum? Sounds like that would cause shooting ducks.....

    I think you should be running more than 6 lbs of fuel pressure to start with, but have no experience with what Carters will accept.

    With Holley carbs, I like to see pressure around 9 - 9 1/2, and not dropping below 7 lbs on a forced induction engine.

    I had a dual fuel pump setup on my turbo engine, mechanical and a Holley blue, parallel into a fuel block, with dual check valves. Basically either fuel pump would run the engine on it's own, but if one failed I would not melt the thing down.

    They don't have a weighted air valve on the secondaries?

    Default Carter carbs

    Check the needle & seat assembly, stock is a very small orifice and with a blower it can suck the carbs dry. The blower carbs should have a larger orifice
