An interesting data log that I took yesterday...
Very unscientific, just shown for discussion. The runs were done on a back road, track data logs will follow in September.
Four 2nd gear pulls from about 10 mph to 60 mph followed by four second gear pulls with the rls water/methanol injection.
The green lines are the intake air temperature. The top green line is without water/methanol injection, the lower green line is with water/methanol injection.
This is with a dual injection point configuration: primary injection point is at the intercooler output tank, secondary injection point (with a very small nozzle) is directed at the *outside* of the intercooler core. This explains why the IAT's continue to drop after each run when the water/methanol injection is activated. The water/methanol continues to evaporate from the core and cool IATs.
Speed traces (red) don't overlap perfectly, I was going back and forth on a closed section of road.
Testing notes: rls Intercooler on all runs, rls Injection on last three runs: 50% distilled water, 50% methanol (by weight), ambient 80 degrees F.
