SINGLE PLANE VS DUAL PLANE, WHICH INTAKE OFFERS THE BEST AIR FUEL DISTRIBUTION? FULL DYNO RESULTS!


SINGLE PLANE VS DUAL PLANE, WHICH INTAKE OFFERS THE BEST AIR FUEL DISTRIBUTION? FULL DYNO RESULTS!

Years ago Freiburger and I spent the day on the dyno at Westech to see how nitrous worked with a single plane vs dual plane intake manifold. To test it we sprayed the same shot on the same engine with two different intake manifolds, with 8 oxygen sensors. That meant we could test each cylinder. Just like Richard is doing in the video below. So if you want to see what each intake really does, check it out below.

WHICH INTAKE OFFERS THE BEST AIR/FUEL DISTRIBUTION? HOW CAN A MOTOR GET HURT WITH A PERFECT TUNE? WILL MY MOTOR BE OKAY IF THE AF METER SAYS IT IS SAFE? HOW TO TUNE AN LS! CARBURETED AIR/FUEL DISTRIBUTION. SINGLE PLANE VS DUAL PLANE, WHICH INTAKE MAKES THE MOST POWER AND TORQUE? CHECK OUT THIS VIDEO WHERE I COMPARED A SINGLE-PLANE EDELBROCK VIC JR. TO A DUAL-PLANE, EDELBROCK PERFORMER RPM INTAKE FOR POWER AND AIR/FUEL DISTRIBUTION. BOTH INTAKES WERE RUN WITH 8 OXYGEN SENSORS, 1 IN EACH OF THE PRIMARY PIPES OF THE HEADERS TO MONITOR THE AF RATIO IN EACH CYLINDER. JUST BECAUSE THE AF METER IN YOUR EXHAUST SHOWS A SAFE MIXTURE (AN AVERAGE OF THE 4 CYLINDERS), DOESN’T MEAN THE MIXTURE IS SAFE IN EACH CYLINDER.
