Questioning effectiveness of WI - only 5 celsius less!

[awdrocks]

I had the same problem with my test last night. I have a roots blower. I like 10cm before the throttle body and the water has to travel through my supercharder first then through my water intercooler... I saw NO drop in inlet temps. Also very disapointed. I live in Cancun and its very humid here, but also hot.

I did the test in nuetral and stationary.

But what you mentioned made sense. The effect will most likey be inside the combustion chamber, therefore the inlet temp senser not reading the lower temps. So my question is. If that the case would it be a good idea to get a EGT Guage to messure your exhaust temps to see if those are dropping conciderably?
