Does anyone have this installed on their car and have any pictures of it? Trying to see more photos of it on other peoples builds.

I do, but on a plane and can’t upload pics but you can stalk my posts until tomorrow. I’ll upload some when I can.

I’m also worried about when it rains. Has anyone had any issues with water in the engine bay because of the louvers?

[BradMX5]

From the amount of cars I've seen driving around with no hoods on I'd think some rain through a hood louver wouldn't be an issue.

Can confirm water from rain and washing is not an issue. Anyhow here are some pics.

Just watched this install video and i just shook my head with all the cutting. I don’t think I have the cahones to bring myself to do this mod unless there were some real cooling or lift issues identified with the car.

More power to you, defintely creates a new look to the M2. Just make sure you go with a well trusted shop and craftsman.

My 996 Turbo came with a louvered engine cover. Washing or sitting out the rain resulted in the accessory drive getting wet.

Upon cold engine start I'd have to let the engine idle a bit extra to give the accessory drive time to dry. I'd hear intermittent chirps and the battery voltage reading was low (~12V) because the alternator was not being driven.

Also, the engine air intake box would get water in it. There was a small hole in the bottom to let the water drain but it got wet enough to wet the large paper filter along the bottom. (I could see the staining of the filter element.)

I was careful when washing to avoid flooding the engine cover with water. Rain of course -- even in one case just heavy fog -- can't do much about. (Car cover not really practical.)

What I don't like about the louvers mod on the M2 is this I believe will cause air flow the wrong way through the engine compartment. If it even affects air flow. The location may be in a neutral air pressure area there may be no flow out of or into the engine compartment. Taping lengths of wool yarn to the louvers then observing the wool yarn behavior one could see which way the air flowed at various vehicle speeds.

Normally air enters through the radiator openings and then because the engine compartment is sealed at the top flows down and past the turbos, exhaust and thus the hottest air flows away from the more heat sensitive items like engine wiring, fuel lines, etc. This downward/outward flow is helped by under car aerodynamics which creates a low pressure area under the engine.

With the louvered hood mod if it works at all the radiator air has another escape route which means it doesn't flow down and remove the hottest air out the bottom of the engine compartment but flows up and the hottest air either follows it or just kind of stalls and this lets the turbos/exhaust heat load increase.

With the louvered hood mod there is also the concern hot air that exits through the louvers then flows into the cabin air intake and puts more strain on the A/C system.

I might add in the case of my 996 Turbo the engine was at the back of the car. There was an active spoiler which created a high pressure area *over* the louvered engine cover. Thus air was forced to flow down through the engine compartment and remove the hottest air.

Plus there was an engine compartment fan which ran all the time and blew down so even if the car was not moving fast enough for any real pressure to build over the engine compartment cover the fan ensured cooler air entered at the top of the engine and then flowed down around/past the engine and the hot turbos/exhaust and out the back of the car.

To each their own. Here is my opinion.

I installed this mod primarily because the look of the stock hood was too much for me. I preferred to have one or two carbon vents to offset the massive solid car hood landscape. Again, my opinion that it was just too big and plain.

As for the water, I cannot comment on any other vehicle or configuration, but I live in South Carolina. It rains often and hard. So much so, we flood regularly. I can assure you that lashing down rain and washing does nothing to negatively affect the engine, sensors, filters, etc. on "this car" with "this specific mod."

As for the air, I chose to trust data and research from Verus, Jackie Ding and PhD Racing as seen here. I do not think there is any air-flow in wrong direction that would be any impediment to proper air flow. See pics 1, 2 and 3 below.

Finally the install. I do not trust anyone. Only myself. If you are not comfortable with this level of work, my advice would be to skip it unless you do really trust someone you know.

This is basically it. At the end of the day it's a mod that is not for everyone and everyone will have an opinion. Here is mine. Do with it whatever makes you happy. It is your car.



Cheers!

If Verus says it improves airflow in some way and lowers temps in any way I would 100% trust their claims.

Their products for the ND Miata are fantastic and make claimed improvements plus some.

Given the massive engine cover over the M2 engine I have to wonder how real that air flow graphic really is.

With my M2 I see no variation in oil temperature once the engine is up to temperature.

Even if I drive the car aggressively.

What I do see is the coolant temperature drop (!) as the engine controller opens the floodgates (sort of...) and deals with the increased heat load. (See pic....)

Engine management is quite able to deal with the heat and the car's existing cooling system related aerodynamics is obviously up to the task.

Without any opening in the hood.

Thus the mod is just a solution looking for a problem.

Speaking of the engine cover... This raises the question of where the water that the louvers let fall on top of the engine cover where this water goes after it runs off the cover.

[Carefree]

My degrees are not technically based but it appears if the G87 needed additional cooling it would have been engineered by the designers.

To the average (emphasis) owner this louvre makes about as much functional sense as those silly wings.

YMMV

[RobM2]

I also don't see the problem this is solving — my M2 has remarkably stable oil temperature even with spirited driving. It is generally around 210°F.

Coolant temperature on the other hand is all over the place, but I am mostly surprised how low it gets when whatever duty cycle kicks on, not how high it goes.

what front lip is that? i’m digging it. looks like it lowered the front more than other lips or just an optical illusion

This thread is hilarious. OP asks for pics bc he is curious about this mod. It turns into another "this is just a solution looking for a problem" bash.

I did this solely for looks, as stated in my post here https://g87.bimmerpost.com/forums/sh...11&postcount=9

Anyhow, opinions are opinions and everyone has their right to their own and for their own reasons. But good lord, lighten up folks.

Thanks. It's the Maxton front splitter V.3.

Correct me if I'm wrong, but at least on the supra this and/or the better intake manifold severely decreased IAT which is fantastic for track use. Allowing more airflow through the engine bay and exhausting the hot air that builds up in there really drops the IATs which keeps you at full power (no timing pulled) for longer durations on track.

Never did it on the supra and probably won't do it on the M2 because I can't bring myself to do cut up the hood haha

. I spent $1500+ on a carbon intake that does sweet f-all. Like a 1/10 increase in induction noise and a 0/10 increase in performance with a stock DME tune. But it looks good. At least I held myself back from the $3k intake that does just as little and only looks a little bit better.

lol

I emailed PHD racing and called Verus engineering and asked if they have had any issues/complaints or if there will be issues because of water form rain or washing the car with the vent installed. PHD said that most of engine is IP67 rated and it shouldn’t be an issue from water. PHD also mentioned that I would probably have to do a little more cleaning of the engine bay because some water does get into the engine bay. Verus reported that they have not received any complaints or issues from water damage on any g87s who have the vents installed.

Thanks to anyone who sent photos of there car with the vents installed.
