9-13, 9/14-03 temp study
by Greg Heumann
Probe #1 9/13: - Outside @ driver's side MAF
Probe #1 9/14: - Ambient - @ UF Motorsport loc. in front of radiator
Probe #2 - Inside driver's engine air filter box
Probe #3 - At driver's side OEM intake
Day 3:
On freeway, steady cruise, equilibrium.
Off freeway 3 minutes, driving into town, stop and go, <30mph
Pre-start, after parking for about 10 minutes. Wow!
Post-start, 30 seconds. Still in town. Inlet temp very high - drawing hot air down from above.
On freeway for 1 minute, 80mph cruise.
We go to great lengths to test for you! Note the temp!
Day 4:
Relocated P1 - no longer measuring upper engine compartment temp; now measuring outside air. This location is about 2" forward of the UF Motorosport sensor recommended location.
Hard driving - Outside air 89; inlet temp 91, air temp at airbox 100 (I'm including a correction of +2 degrees for this thermometer.) Total rise 11 degrees f.
Hard driving, downhill section. Speeds still high, but much less power in use. Outside air 87, inlet air 89, airbox 109 (corrected.) Total rise 22 degrees f.
