318 draw through build

Very cool setup!
Are the reed valves used in the same way as a blow off valve?

I have an old Offy under/over carb adapter for a draw-through setup. Basically the same concept. It did bring the carb up around 2" from stock.

No, the reeds close up and direct all of the charge to the turbo once boost is made, they don't bleed boost off.
