Well here it goes so far I have the offenhouser 4 bb intake I have the edlebrock wideband boost gauge have the holley blue fuel pump and the boost refrenced fuel regulator Mallory distributor and going with and HC1 turbo external waist gate and doing brake lines for the oil lines. My questions are 1. I have a chance to get a 750 holley blow thru carb for 200 $ will if work? 2. What should I do about timing the boost without having to buy a msd boost timing master I'm in the service we don't make that kind of money. 3. Getting copper intake gaskets and copper head gasket for the oils girl is that really needed for head or should I only worry about the intake |

Welcome! 1. I wasn't aware that Edelbrock sold a combination wideband A/F meter and boost gauge. 2. The Holley Blue pump with the factory relief spring is only good for about 9 PSI boost in a blow through application. I would use a pump meant for port EFI. 3. The Mallory distributor doesn't get you much except for a more easily adjustable advance limit. 4. What turbine housing is on the H1C? 5. You want a carburetor in the 400 CFM range, but they aren't available new. I would put solid floats in an Edelbrock 500 AFB. The 750 is much too large. 6. There is an HEI module that will retard the timing when activated. Use a pressure switch. Otherwise hack the vacuum advance can so that it can do pressure retard. The Hugh MacInnes book details this. 7. No special manifold gaskets are needed. If you keep detonation under control you probably won't need a special head gasket either. |

So it's a .54 'll 7 blade compressor and the edlebrocck is just an o2 sensor haha have any good ideas on where I can get a decent carb been looking everywhere and can't seem to find one was going to try and mod a 1406 edlebrock but finding the floats and the right stuff to go in it seems to be a lot of ppls issues the boost gauge I have is just a mechanical one and I thought the holley would be ok for my fuel pump . I have a different fuel regulator that has a spot for boost to hook into it. |

Have you read the Hugh MacInnes book? If not buy it before you buy one more piece of hardware. |

Go for the latest printing. Read that book to get an idea about the mechanical, pneumatic and heat aspects of turbocharging. Understand that the turbochargers and controls presented in Turbochargers are dated, but the concepts are grounded in physics and are solid. For what the Boost Timing Master costs you can buy an assembled Megasquirt 2 and get 3D ignition mapping rather than 2D and that gives you an upgrade route to EFI. If you know for certain that you won't ever want EFI I'd use Megajolt for ignition. |

Well I have a holley projection 2d setup sitting in a box just need a better brain to run boost but once again won't that be to much cfm |

That old ProJection has some decent hardware. A member here, Dart270, ran the old analog ProJection and then converted it to MegaSquirt. His car though is naturally aspirated. If memory serves the injectors in that throttle body flow about enough to make 275hp which is pretty decent. The CFM deal with carburetors really has to do with velocity and signal strength. With too large a venturi or too small an engine there isn't enough vwelocity through the carburetor to produce a strong enough vacuum signal to operate the fuel circuits. EFI doesn't have that problem. Too large a throttle can be tamed by a progressive linkage. |
