Had a fairly productive day with the Z today, got the oil cooler block off plate installed so that I can enjoy the last month or so of driving season here without worrying about the oil temps being so low. I also ran ducting for the G3's and installed the front chin spoiler that has been sitting in my garage for 3 years!

Block off Plate:


Ducting:


Ducting installed with mesh grill:


It was a bit tough to get the bumper back on as the 3" duct and oil cooler lines on the passenger side made things pretty tight. The bumper is in pretty rough shape too after hitting a couple shingles that fell off a truck on the Hwy Looks like next spring it'll be time to peel the clearbra off the bumper and get a new one put on.

After going for a cruise and monitoring the new intake air temps, I can confidently say that the ducting for the G3's does work. It is 18 degrees Celcius here today, and after everything was warmed up (oil at 90 degrees, coolant at 83) while idling the intake air temp was around 38-40 degrees Celcius. As soon as I started driving again I could watch it dropping to around 27 degrees, and once moving faster 23 degrees Celcius. That's about where it stayed with Highway driving, 4-5 degrees C hotter than the ambient air temp.
This is a reduction of about 5 degrees from before I had the ducts. (I would see about 28C as the low temp on the hwy given the same ambient temperature) It'll be interesting to see come next summer how close to ambient air temp the IAT stays as I used to see intake temps of 58C when it was 28C outside

As we know each drop of 1 degree Celcius is equal to roughly 2.71 WHP, so when I appy the formula 5*2.71 we see I picked up around 13.5 WHP!
