Like I've said, there is an engine cover that covers the spark plug wires which makes the M7, and the NM not fit like the '07 to '10 models. My statement was that the design was for an older MINI, not the later model.

 

I'm sure one will be designed. Unfortunately for me I already did my design. See picture

 

I installed an M7 and am quickly finding out that my intake air temperature is higher by 12-15 degrees while driving. While stopped or in traffic the temperature reaches well over 108-110 degrees. Ambient temps outside were 58 degrees. Took the heat shield off, driving temps were now within 5 degrees of ambient and sitting and traffic never got above 80 degrees.

This is the issue...I think the heat shield is throwing extra heat straight to the inlet intake tube. More heat = less power!

Toughts?

NOTE: stock Cooper S under the hood.

 

retrofit piece of aluminum flashing/ducting (that goes below the hood air intake) on mine yesterday. The flashing is covered by a prior BMW service bulletin about hood vent problems and can also be used with the smaller underhood insulation that just covers the area right near the hood scoop and turbo. Mini seems to have discontinued all underhood insulation several years ago. First car I have owned w/out any in many years. I did it for both heat rejection and a bit of noise moderation.

Need to see how effective it will be over time and w/ hot days. Certainly hood scoop is now well buffered from turbo heat.

 

Does anyone have anything to add here? Sounds like a good observation worth considering..... I was thinking about getting one of these but not sure now....

 

I read this also and it doesn't make any sense to me. Not just the idea that the M7 heat shield could raise his intake temp, but all the numbers he uses don't add up in any logical way. I'm not saying slim is wrong, I just don't see how this can be true. Furthermore, I have never heard anyone make a claim that is anywhere close to this.

Almost all heat shields work in a similar manner, they create a thermal barrier to block the radiation of heat. The type of heat that damages the hood-scoop and makes the hood hot to the touch is radiant heat. Both the M7 and NM sit above the turbo but do not enclose the turbo. The M7 design differs from the NM in that it has the "aerogel pad" which adds an insulating characteristic to its function. The idea of "throwing extra heat" in any direction I don't see happening. I might consider calling Peter at M7 and the guys at NM and ask if they have any input on this.

 

My experience: after melting the original scoop on my 2008 R55, went with m7 Ram scoop and NM heat shield. No issues with melting any more nor the "higher intake" temperature...
I did see on another Clubman from my club an "issue" with m7 heat shield: he had one of his bonnet stripes "burned" by heat coming underneath the hood just where the heat shield ends... Stripe Vinyl was totally destroyed...
I am driving an 2011 R55 now, and planning to get updated version of NM heat shield for N18 engine as well as new m7 ram scoop (as my old one was damaged at the dealer's body shop while being repainted in to white silver )...

 

NM now has a version of their Titanium Heat Shield that fits the 2011. I have it on mine and immediately after a 3 1/2 hour Interstate trip to Atlanta, I could comfortably rest my hand on the hood scoop. Before the heat shield it would be extremely hot after a 1/2 hour drive to work! NM customer service is excellent also. While installing, I lost a screw in the engine compartment and they sent a replacement within days. Call NM sales, ask for Jerry Tambayong (tell him Jerry from Savannah sent you).

For whoever ask, the shields don't cook the turbo as they do allow air to flow around it.

To help hot air escape the engine compartment and to allow more cold air in, I have MiniFini's "Black Intake Scoop Grill":

Way at Way Motor Works (WMW) has a much cheaper shield that attaches to the hood that I've heard good reviews about:

This look like a good alternative, it actually throws air at the turbo...

+1

anyone got any experience with it?

 

i got the nm heat shield too and the hood cover from wmw, works great!

 

Does anyone know where to get one that they use in the German MINI Challenge series ?? Mine has just started to warp so am looking for alternatives - I would rather vent the air than trap it in though...

My vent:

The challenge one:

 

ohhhhhh thats so nice. I want one now, eventhough theres nothing wrong with mine lol.

 

Part numbers for that if anyone can help: http://www.realoem.com/bmw/showparts...83&hg=51&fg=95

 

Not good! Definitely early onset hood scoop warpage. It's all down hill from there. You need a heat shield. BTW,the Challange cars have a big deflector under the hood that is attached to that scoop. Deflects the air down onto the turbo.

Good Luck

 

Yeah it is a bit annoying - have dropped a message to a dealership over here to see what my options are (still have 2 years of warranty to run on the car) so am hoping there may a couple of options... Im kinda hoping I get offered the JCW carbon scoop so I can sell it and then put the funds towards the challenge one

Dont want a heat shield as that will just trap the heat = not dealing with it properly. I want to be able to either vent it or feed cool air to stop it happening...

Yeah, seen that deflector not sure if it has to be fitted or not - those grills on that scoop kinda imply that it could suck air out from under the bonnet too...

 

This was going to be my first under-the-bonnet purchase; but after reading this thread, I'm still unable to come to a conclusion on these heat shields.

The NM seems to allow less air being trapped around the turbo, but yet heats up itself and causes its own radient heat. The M7 seems to be an unhealthy choice for the turbo just because it is too much of a blanket.

I'd like to get a part that will keep the engine compartment cooler and solve the hood scoop warping issue without sacrificing turbo longevity. What would compliment the heat shield to cool the turbo (an additional part)? I don't like to scoop cover - doesn't that take away the cowl induction?

 

there is no cowl induction, there is a tube that is next to the driver side headlight that gives all the air to the engine, what you can do is make more holes in the scoop grill and put a heatshield the wmw one that goes under the scoop, i have a NM engineering heat shield, and so far i have no complaints

 

Can anyone tell me how they argued the point with their local dealers to convince them to give them the CF scoop?

 

I have the nm shield and backed it with cool tape I picked up at oreilly. It works pretty good.

 

Hi, folks. I've had my M7 shield on for almost exactly one year and I'm seeing the ol' warping creeping up again. Love the shield and it did prolong the life of this, my FOURTH hood scoop. I posted here:

Ok I got my SA to install the factory shield on the hood, covers the turbo area and lets air in and then added self adhesive reflector material , avail on ebay etc for like $20 a 12x12 sheet and put on front of hood opening which is directly over turbo and I used a no touch thermo for before and after , the temps went from reading 160-180 on the hood to 130-140 and no signs of warping and you can actualy hold your hand on hood after 10-15 mins of heat soaking.

The shield was installed on 08's but I guess they thought the vent holes was the cure, it was not. It's only like a $15 part.

I don't like the idea of the shields that cover turbo and trap heat into motor.
