Engine Coolant Radiator

RAF Marham trackday testing

Final test was a day at RAF Marham having a thrash around a runway track.

Data logs recorded via IPAQ. From these I extracted data for coolant temperature 

and manifold air temperature. For direct comparison I have included plots from 2 

previous years at the same venue.

 

Coolant temperature plots:-

The first 2 plots show average temperture around 91.5degC, the last plot  

from the recent trackday shows the average has dropped about 1degC.

 

Following plots are for the manifold temperatures (post turbo).

 

First of all the numbers from the data stream are not linear to temperature,
having plotted the numbers used in the ecu a approximate DegC scale can 
be overlayed.
 
Average Temps:-
October 2005  45degC  Ambient cool
Sept 2006       49degC  Ambient warm
April 2007       39degC  Ambient warmer
April 2007       46degC  Ambient hot (early afternoon)

 

Later in the afternoon when temperatures had risen, this plot shows 
MAT which is at similar levels to the previous years plots where ambient 
temps were cooler.
