I setup a methodology of testing: I needed some guidelines to adhere to in order to achieve accurate results and be able to get reliable
data. I got in contact with people more knowledgeable than myself with the way this sort of testing should be done and established this set of
testing rules. The people involved in creating this set of rules included: the manufacturers of the intakes, a certified infiniti tech, multiple
people on the G35driver and my350z Forums, and myself.

I tried to create a level “playing field” for all the intakes by keeping the variables to a minimum.
- The Vehicle remained strapped during the entire 6 hour testing period
- The dyno cooling fans were blowing on the car at a constant speed; the angle in which they blew also stayed the same.
- The hood remained open, to help rule out heat soak on the intakes
- Before switching each intake the battery cable was disconnected and the brake pedal was pressed and held for 10 seconds (this is the
known procedure for clearing the g35/350z ECU)
- Each intake was given the same amount of time to cool down, and the same amount of learning time (around 30 minutes cool down, 10
minutes learning)
- The ambient temperature range and humidity was relatively stable at 77 – 81 degrees F and 20 – 22 %, respectively
- The intake air temperatures were monitored to make sure each intake wasn’t suffering from heatsoak
- Each intake was given at least 3 good runs, if there were any spikes or oddities it was discarded and ran again. By the 3rd run heat soak
became a variable. The first and second runs were always the highest.
- Engine Coolant temps were also kept stable between intakes
- Each intake was to be data logged with Osiris Cipher
- Each intake was to have a sound recording done (2 feet away from engine, same location every time)
