There was a thread started in the fuel system section a few days ago on draw through turbocharging. My thoughts on draw through and blow through carby turbo setups are the same, Its a very crude way of fuel metering.

 

What are you trying to achieve with the vehicle or engine?

Hey Bryan3976. Not sure what you want to put it on but if it is an L series, blow through will probably cost you more than a cheap aftermarket ECU and 280zx type inlet manifold. I had one on a 180B and it was good but it had a turbo specific Webber carby and all the tuning was already done.

You need a float which won't collapse under pressure, fuel reg that has a vacuum diaphragm so it keeps the same pressure under boost, probably you'll need to modify the dizzy so it retards more under boost, plus you will need an electric fuel pump if your is a mechanical one. You also need to get a really good seal to the carby which is easier to say than do. Then when you get it all together you need to tune it, which is a challenge with any carby unless it is designed for a turbo. Holleys aren't too bad because of the range of jets and parts available. Get an old V3 Wolf or microtech  with a hand controller and see how easy it really is. Honestly you'll never look back.
