Hey Snowtoy... .where you been!!
I have missed your "input".
Yes, a change in intake air temperature on my dyno software will show a change in Tq and HP. Ambient air intake temperature on a stock 22RE from 60d F to 100d F you will drop about 4 lbs of average Tq and about 4 HP. So about 1 lb. of torque and 1 horsepower drop for every 10d F the intake air temperature raises.
Air density is usually higher with lower air temperatures, but not necessarily always.
Driving my 22R 1985 during cooler AZ temps and higher relative humidity there was a noticeable increase in power... not a lot, but I could feel it.
Gnarls.
