The guy who owns the engine we will be dyno'ing has a set of 48IDA's on it right now and what we are looking to do is a comparison test of downdrafts and sidedrafts of the same size and then try a few more pulls with an all out race setup with a set of 55's to see how much power we can get from the motor. With the longer runner we are hoping to get more usable torque and horsepower over a broad rpm range. I'd like to also try it with a 4bbl as well but we won't have the entire days use on the dyno.
