0-180 MPH IAT LOG
Ran in a 1 mile LSR event yesterday.
This log is with Eurocharged software. Car ran 179.7 mph on this run. Ambient was 68-70 degrees. Have logged many 1/4 mile runs where IAT'S go up the entire run. Never logged a 1 mile run, Temps are higher at peak rpm, each time the car shifts temps they come down slightly. I was very surprised to see this. I expected they would continue higher as speeds increased. Under 120 F. at the end of the 1 mile run which took approx. 30 seconds

Wow thats pretty good. Are you running with ice tank only or tank and front cooler as well?
My 1/2 mile was at 120* every run and it was 80* outside.I am going to try the ice tank alone next time. Really want to go to your event as well but will see !!

That was going through the heat exchanger as well. I could not believe the IAT's were dropping on the 3-4 shift and again on the 4-5 shift as RPM came down. I am now wondering about just a little smaller supercharger pulley ?

It's interesting that in 5th gear the IATs are actually dropping. I guess that's when the airflow over the H/X gets high enough to take more heat out than the I/C is putting in.

It actually drops twice. Once just after the 3-4 shift then continues up and again drops after the 4-5 shift.
I guess a combination of air flow and the blower speed dropping after the shifts.

What's your boost? Like @15 psi? Can't really tell with your graph. High boost creates high heat, they say.
Keep it coming, brother. More M113K's needs to be in the mile events!
