Intake Air Temp Log

[Rusty]

Decided to do some logging of the IAT today. Ambient is about 10 degC and it's quite breezy but not damp.

Car is an RS2 spec S2 with RS2 intercooler and OE inlet.

Here's the graph:

That looks ok to me. A bigger cooler will definitely make a difference. On average cruising my temp difference is about 5deg and if I am at 70mph sometimes 3deg from ambient. On hard runs it will rise to a 10deg difference

That starts after a hard 5 mile run and then sitting while I set the computer up. I then drove back down the same road with revs as shown.

Bigger cooler is something to consider; I think a full Wagner kit may be a good plan.
