My boss is now 2 days old,when I lifted the hood I noticed the underhood insulation covers most of the vents. Has anybody cut or removed some insulation to make the vents work better?

I would find out the design intent before trimming it away. The engineers don't just do things haphazardly. There has to be a reason. I will be on track this weekend with a Ford engineer that has a 2013 LS and will ask him if he knows.
Is that opinion based on the wind tunnel testing?jeepinocala said:cloud9 said:I saw that on a 5.0 that was in my dealers showroom.

I dont think it to HELP air flow at all. I would guess they dont want the rain running on the motor.
I'll be surprised if you can achieve that if you're really pushing the car to its limits on track. If you do, let me in on the secret. I have the following cooling mods:BossDuke said:My '12 LS will show 220 in stop and go traffic, especially in summer heat with AC on. I am progressively addressing that in the order: 302s grill (done), Fluidyne radiator (on hand), then real oil cooler and racing louvered hood as required. I want the street temps at or under 200 at all times. If (when) I track the car, I'd accept 220 max. I noticed the LS I drove at the Boss Track Attack ran at 220 in mid 80's weather. It had all the mods I'm planning except the hood. If I had a '13, I'd be pretty confident I wouldn't need the racing hood to meet my objectives.

That's been partly holding me back as well. However, I'm not sure that opening up the exhaust via headers and an offroad x would generate more heat since you're allowing the exhaust to flow better, even though it adds hp. ??? Advancing spark timing would obviously generate more heat and from what I've seen there's not much left on the table in that area anyway......which might be why the Boss runs on the hotter side to begin withBossDuke said:I guess the biggest reason I've pretty much decided not to go for any major power increases is I'm not sure how to handle the increased thermal load with the cooling design limitations.
