Hood cut out dimensions?
Hood looks great! I want to do the same. Do you know the dimensions of the cut out, and some advice how to cut it out. I have never done anything like that. I don't want to mess it up.
Thank you,
J

I agree that coolant/oil control is needed to control heat in the engine, but neither have a great affect on underhood air temps except making them higher. IAT changes can mean significant HP swings and the only reasonable method to control the upper underhood air temp is through air flow, such as scoops and vents. If the OP has an intercooler it adds to the problem.
Your ewp is probably the key to lower coolant temps in stop and go traffic, which seems to be the OP's problem.

To effect real changes in running temperature, one would have to vent the area immedately after the radiator. Just one or two inches of vent past the radiator yields real results.
Anything else is just window dressing. Even though a hoodless or mid-vented hood effectively vents heat after the car is parked, it is not the same principle as a car in motion with the engineered airflow through the engine bay.

It was quite a while ago when I did the hood. I measured the mark out about 10 times to make sure I got the dimensions right. Used painters tape to protect the hood and made the outline with a marker on the tape. Then I drilled 4 pilot holes in each corner. Next I used a jig saw with a fresh bit and carefully followed the outline on the tape. Then I used a hand file to smooth out the cut, and finally picked up some weatherstrip at the O'Reilly Auto parts to finish it off.
Good luck man!

Will take some pics and post them when i get back home later, heat likes to rise so when engine is running with the hand over the hole is like the fan is rite under blowing out.

one mor hole pic...
Just resent so haven't finish liner inside as of yet, not a priority rite now.
Liner was cut neatly so finishing it will be easy, because the air flows outward the liner is not been thrown around at all.

I picked up an extra hood cheap from someone who put an aftermarket hood on his car. I'm going to customize it with louvers. At first I was thinking about louvers on both sides but I see Mustang and Viper do it like that. So now I think I'll do it in the center like the C7. I could buy the stock plastic unit but I think I'm gonna make my own in f-glass and mold it in. Another project this winter.

Awesome!
OK, call me crazy, but here it is. Actually the cut out went easier than expected. I have to tell you, it looks pretty good. I am planning to buy a World Challange hood, so I really didn't have anything to lose. I am going to give it some street time and see how it goes. Thanks for of all the feedback, I knew there would be some aggressive comments about this idea!
