It would insure the sensor would not be effected by the aluminum at all, and probably give 100% accurate temps as measured right before the air is ingested (forced?) into the engine? This could be a down the road mod of course. |
That is what I thought at first, but the IAT I have on there now doesn't heatsoak. I think the sensor is surrounded by ceramics because even sitting in the pits it will still read the correct air temperature. I used to have a push-in type that would heatsoak like crazy, reading over 130 degrees after a few minutes waiting in the staging area. Thought that was the reason why I couldn't get the full 20 degrees of timing but even when the IAT is reading low I was still getting only 15 degrees. That is why I think the intake manifold is the culprit, aluminum transfers heat very fast.
I would like to put the IAT in the manifold but it is a 3/8th NPT type and it needs to be in the direct path of the air to read the meth cooling.
Boost leak test was completed and I took it for a test drive, car ran great. Felt just like having my ported intake manifold on, but I will need to test it more tomorrow and eventually at the track next Friday. DA might be around what I normally race at, so it will be a direct comparison.
