Does look kinda ugly but if what this guy says is true it would be worth it for someone who is looking for performance. I might give this a try.

I'm over on Acurazine frequently. Alot of information over there crosses over to the 6th and 7th gen Accords.


Inaccurate is a really cool member over there. He has numerous threads on performance mods. He does his research and presents data VERY well, so everyone can make their own decision to do that specific mod or not. He has been modifying cars along time beginning with American Muscle.



According to his before and after temp readings, this cooling mod works. This mod moves more air in the engine bay. Helps the heat escape...
It's another method to reduce heat soak. Reducing heat soak prevents or slows down loss of power.

Sure, it's not pretty, but it works. Function over form.

Hood risers, deleting AC will help way more.

This mod won't be that much noticeable. I've raced in 100+ degree temps, with track ground temps exceeding 150. Causing my engine temps to exceed the comfort zone.

Excavating heat from the engine is beneficial, however the air flow to the radiator will keep engine temps down, i.e oil temp, and water temps. Those are the two biggest factors to engine failure. Over heating causing expansion/warpage of cylinderhead/block assembly. and overheating oil temps, causing improper lubrication.

It is an old muscle car trick, they stack washers on the hood hinges to raise the back of the hood to allow heat to escape. This way is prettier than that.

I would love to delete my AC system, but, since the defrost is tied into the AC system you would lose that feature. I don't wanna deal with windows constantly fogging up during cold weather, unless...you have a solution.

popped hoods look like ****

this seems like a slightly less ugly solution

the acura member fails in my book, by cutting out plastic in the fog area he has lowered the amount of air being vented to the radiator.

i would take any advice from this guy with a grain of salt
he removed the front and rear metal bumpers to save weight
any major accident he has now will GUARANTEE frame damage

not to mention how much less safe the car is now

Why? My hood is raised an inch to excavate heat, allowing proper flow from the radiator out. the front of my radiator is boxed in to direct air flow. How is that for civic and integras? Cooling is cooling, and if you need to keep the engine cool, sometimes there aren't other options.
This Acura owner however has got it all wrong. Just because you cut a hole doesn't mean when you're going 100 mph, air is being vented through the radiator. You need to actually direct air to it. Honda and Acura from the factory tested these bumpers they designed for sufficient air flow at high speeds. It's the air flow when the car is moving that cools the engine down. The Fans for the radiator is just there for idle, when no air is being pushed through.
Something as simple as removing your under carriage will throw the air flow out of wack and you will over heat on the race track. Trust me, I've tested all the methods on the race track.

Wouldnt it have been cleaner to just trim vent slots at the top (or bottom) of the cowl covering.

This cooling mod works very good for hot days in slow moving traffic. It is not mentioned yet in this thread but you will lose the clean outside air for your air-conditioner as this opens up a direct line from the engine bay straight into the vent that pulls in the outside air for your air-conditioner. It is just something to think about before you do this cooling mod. Most just run their air-conditioner on recirculation.

This is what my cowling looked like after doing this mod.

Some cooling mods look hideous- others are controversial based on aesthetic opinions- each to his own- i propped rear of my hood with nylon spacers
1" thick and stainless steel washers and bolts on either side, from hrdware store.
I spent 7.50 - if i get tired of it. No big deal- it works well and helps the outlaw thermal intake and throt bod spacers.

because the fans are only good for Idle. The radiator is cooled by air flow when the vehicle is moving. A fan will never beable to replicate what a moving vehicle+wind can do.

I think ya have this thread all wrong. Look at the Acurazine thread. There are various ways to complete this mod as per YOUR liking. Innaccurate is a 50 year old with a 2800lbs TL.. No back seats, racing fronts, no liners, no wipers, no radio.. His threads are VERY informative and always a good read.

I have this mod. My Manifold temps dropped 25-40 degrees while running... its always cool to the touch after a drive

Look at post #309 from the thread to check out other forms of this mod. Popping the hood in not necessary. Depends on how you want to do it.

And when done, you dont even see the cuts or holes... I always find myself showing it to others.

I do have a TL, so I dont know how it'll sit in a 7th gen

I agree on the popped hood. Looks bad.

By cutting the plastic, now you have more air flowing into the engine bay. I would rather have my engine bay at 120F after a long hot summer drive than 180 without this mod.. Our (TL) engine bays are damn near air tight.. air can not escape with the weatherseal, and no holes...

As for his bumper removal, he knows the safety risk. Not EVERY "mod" is for everyone. But like I said, he has a 2800lb TL... 650 less than stock..

Is there any drawback to this mod besides the look aspect of it?

The Ultimate Cooling Mod (UCM) is removing the entire cowling. When removing the entire cowling you will get the Best Cooling but you will lose your windshield spray nozzles also the clean air opening for your air-conditioner will be lost due to the direct route the engine bay hot air has to the clean outside air opening for your air-conditioner. Most will run their air-conditioner on re-circulation. Also with the UCM there will be the large opening for any debris such as leaves to enter into the engine bay and when removing the entire cowling it does not look very good at all.

This is why others including myself have tried to come up with ways to take away some of the drawbacks of the UCM. The picture below shows one version where you do not lose your windshield spray nozzles, do not have the large opening for debris to get into the engine bay. Also this version has a screen mesh to keep smaller debris from entering the engine bay but you will still lose your clean outside air for the air-conditioner.

If you want to see if the drawbacks will bother you then just remove the cowling for a week to see if the loss of outside clean air for the air-conditioning is something you can or cannot live with. You can just put the cowling back on if it is not what you like. That way you do not have a cut into cowling that cannot be reversed.

None. All cars HATE heat. Im not saying this will give you more hp/tq but it will help not lose it from heat soak. Running your car at 180F and 130F makes a difference. Heat soak kills our engines.

The FULL UCM removes the plastic cowls with the nozzles. But the other versions (cutting exhaust holes) do not and still have the SAME effect. I have the small holes and no debris gets inside them and my temps went down alot. As long as the air has somewhere to go, you'll be good with whatever route you decide to do.

That is not correct. The wipers will always be there, only the spray nozzles are removed with the Full UCM.

Would i be able to cut up the cowling a certain way so that the a/c still receives fresh outside air? Like cutting it around the a/c intake vents, the spray nozzles.

No. Under the cowling is a very large area that goes from one side of the car to the other. The fresh outside air intake for the air-conditioner is on the passenger side but once you cut into the cowling to allow the hot engine bay air to escape the air will travel into and through that large area under the cowling. The air-conditioner draws in all of the outside air from that large open area under the cowling that is normally sealed from the engine bay.
