Almost got everything set up for this test. Hooked up the ram air over the weekend to get the bugs worked out. I should be ready to test all three back to back by next weekend. I will be using a heater core duct taped to my filter box for the HAI and a simple flexable dyrer duct down to the front bumper for the ram air. I suspect that the ram air won't be worth any measureable benefit, but I'd like to test it anyway. If I have time, I'll do a test with just underhood air also.
I intend on testing them all at 50mph, no cruise control, just hold a steady TPS and monitor the scangauge. So what is the best practice in using the ScanGauge for this type of testing? I haven't done it before and am looking for some pointers?
