Lots of Header pics
and datalogging has actually shown that the ice doesnt make a difference. i know a very respected forum member on the sr6 forum (has the c32 motor) has shown this and mike has discovered this as well.
I think my next mod will be a shorty header or HEM's... due to ease of install.
But these look very nice.
can't wait to see dyno.
If you can please dyno a stock car without tuning and one with ECU tuning.

although, i do have proof many times over, in the form of timeslips, when it comes to icing my reservoir showing a difference.
Trust me I find it hard to belive too. so that why I'm getting a new super-dooper gauge.

Two things - assuming a vehicle is in the shade, eventually everything in the car - engine, airboxes, fluids, etc. will reach temperature equilibrium at whatever the ambient temp is where it's located... it's just the way it is. The best a car could ever do IAT wise (without a supplemental below-ambient cooling media added, e.g. ice or dry ice) would (in theory) equal ambient. I don't care if it has 5 HEs and a tank that consumes the entire trunk - it just isn't possible to do better. Take a glass of water and place it in your kitchen, leave it overnight, and measure it's temp vs. the air temp in the room... eventually they'll be the same. Your IC system fluid temperature is no different - it won't magically stay at a temp below the environment it's in.Now, what could be possible is taking the car "cold" out of a 80* garage, or shop, and datalogging in 110* ambient temps outside - presto, the fluid in the tank and IC system would be at 80* for a little while (heating rapidly, though), so it'd be possible to get a post-IC reading of IAT below ambient... but it'd be extremely temporary - i.e. not sustainable, once the car's fully up to temp.
In reality, with a car that's up to temp and in normal driving conditions, even getting IATs within about +10* of ambient is a very good showing, because you have to consider engine-bay heat, solar heat absorbed by the paint, etc. and their inevitable transfer to the intake system. The IC system fluid can only radiate excess heat to the passing ambient air - so it'll never reach ambient once the car's running and up to temp (without adding something colder than ambient to it).
Second - ice should absolutely lower IATs, by artificially (and temporarily) driving down the IC fluid temp below whatever the temp is normally.

As usual, MBH takes the best approach to figure out this strange discrepancy... gather more (and better) data.
