I did some "tuff" testing and there are definitely hot air coming out while at speed...unfortunately, I didn't have anyone to photo this in action...maybe another time...

No improvement in thermal efficiency numbers, better underhood temp measurements or anything?

Come on guys...there's no easy way to measure a before/after temp without a whole lot of extremely careful testing proceedures that I just don't have time for...1-tape up louvers
2-get engine temp to constant known temp
3-get IC to constant known temp
4-travel for known distance at known speed at known ambient temp
5-unblock louvers
6-repeat whole proceedur at least twice
Oh...I forgot that I don't have any extra pyrometers to do this testing
Or...I could give my seat of the pants prediction that "the temperatures are lower under the hood with louvers" because from experience, when ever I opened the door to my oven, my wife yells at me to hurry and shut it because I'm letting the heat out
And you know wives are always right
Sides...when the "tuffs" are streaming away from the louvers' exit, that would mean there's air flowing out

I'm sure after you park, there is significant heat escaping from the louvers as well, and that is a good thing.

I'm just kidding. Glad you like the mod
On the serious side though I was wondering if you had noticed a difference in your IC temps. Nothing scientific.
If you haven't or don't have time Sid that's cool. It was just a curiosity thing nothing more.
Thanks

No doubt that you will come back that you do not have a non-louvered comparison. I am sure that someone will let you put your bum on their hood
or perhaps not but I offer up my hood (gulp
).

You know how this board thrives on documented "how to" pics and perhaps NAM will make it a STICKY

Not even my wife is allow in the garage during these intimate moments...
pic of hood louvers smoothed and painted. and recessed i think... some german (Burli) just posted it over on the DSOC thread. they do look hot...
