Not Ranked
Dyno 2000 results for my engine show the following for single plane vs. dual plane intakes. At 3500 rpm I lose 3 hp and 4 ft lbs torque by using the single plane intake. After that the single plane takes over. Really a "no brainer" if you plan to run a few races at the road course or drag strip. I also agree that giving up some low end torque for power in the 3000 to 7000 rpm range may be a good thing in a 2400 pound car with 400 or 500 horsepower. Even on the street if you really run it you won't be under 3000 rpm very long and if you're just making smoke you're going to lose anyway.
