Decided to measure my IATs. Car was warm. I connected the efi live and went for a ride to do a log. On a 80deg day my IATs were 140city and 110hwy.
I have a K&N CAI and the IAT sensor relocated in the filter. I looked online and wanted to get a svede but they say I will have to modify my banshee hood and I am not doing this.
I decided just to upgrade the existing CAI (that was actually a Hot AI).
I cut a big hole under the filter and relocated the coolant expansion tank (05car). Then I bought Aluminum self adhesive insulation from Home depot and made a box so now the only place it gets air is the hole that I cut.
Went for a ride on that same 80deg. day and my IATs were 82 city and 80 hwy.
So I dropped 60deg of IAT just with some cutting and alluminum insulation.
Here is some pics. and yes I know it looks ugly.
Does anyone see anything wrong with this setup besides looks?
How much power do you lose to high IATs on a NA engine?
I tried to find the answer to this and found things from 1% for every 10deg to density altitude calculators.
So how much power do you lose in percents for every 10deg and is the lost linear.
