Inlet temps (pt II) Options

[GT4WRC]

With my new inlet temp sensor/monitor installed, decided to conduct a few tests.
First was to use a second probe placed between the turbo outlet and WAI.

Ambient temp was 23 deg C

Max temps seen during WOT were..

Turbo outlet - 110 deg C

Inlet manifold - 41 deg C

The above temps were recorded together during the same run. I have no doubt turbo outlet temps could have gone higher but I was somewhat restricted by the public roads I was using

Average inlet temps were around 40 deg C with the lowest seen being 39 deg C. On idle and cruise, turbo outlet was averaging 65 deg C.


Next, the probe was moved to the air filter intake pipe. Air filter is a A'PEXi cone type with no cold air box (yet).
Lowest recorded temp was 33 deg C (while cruising with light throttle) with an average of 45 deg C. In stationary traffic, temp soared up to 60 deg C. Just goes to show the need for a cold air box

Gives a good starting point for future comparisons. Plans include custom cold air box, larger capacity WAI pre-rad, pre-rad water sprayer, more heat shielding under the WAI itself and water injection.
