Okay, I replicated the test tonight with the only variant being the "flow range" on the machine. I moved it up a notch after I secured the back of the machine with duct tape (just a temporary measure for sealing).

On the exhaust side I came up with 110cfm @ 28inH2O with 0.500in valve lift, and the intake flowed 134cfm @ 28inH2O with 0.500in valve lift. MUCH BETTER than 68.4cfm!!!

Although, I'm still not convinced that the machine is anywhere near correct. I'm going to try calibrating the machine myself somehow, and come up with a new multiplier scale if possible. This way, no one else makes the mistakes I did. I didn't flow them at any other valve lifts, so it is yet to be determined whether I'm on the right track. I'll check back in soon as I have results.

MTU 50 & Tony Frank: I'm attending Monroe County Community College, and will be receiving my Associate of Applied Science in two months. After that, I honest to God don't know what I'm going to do. I'm hoping for a chance to get my BSEE at University of Detroit Mercy. That's the degree I initially wanted, and the way things are going in the automotive world, I very well likely could use BOTH degrees to my advantage.

BTW, I'm not embarrassed at all to say I'm going to a community college. After all, we're the only one in the world that has a Formula SAE team!!!
