turbo: blow thru vs. draw thru

Which setup does your friend have? Which turbocharger, Garrett TO4B or Rajay E series?

B.

He has the Rayjay setup. His also has the piece under the carb that bolts directly to the top of the intake. If I remember correctly the turbo mounts to the top of the passenger side exhaust manifold and a crossover from the driverside manny comes under the engine into the bottom of the passenger side manny. That was a mouth full lol.

So this setup produced those kind of numbers?
