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.

Ice + water in the WAI is difficult to do due to the small fill hole on the top. Best option would be crushed ice I guess but not something I plan on trying as it isn't really useful in the real world of everyday driving. Only use would be immediately before a run on the drag strip.

I currently have a cone filter as mentioned and simply plan to design a carbon fibre enclosure to keep out the unwanted heat. A separate feed from under the car will ensure a good feed of ambient temp air.

Water injection will be the tried and trusted ERL Aquamist system. I have used this to great effect on 3 previous cars. System will be set up on the dyno so no idea yet on what boost pressure it will be triggered at. Will be mostly to protect the engine when I throw 20+psi at it
