So I am one of those with the full under bonnet insulation on my R58 JCW. Looking at the thickness of the insulation, I can tell it sits right on top, almost ON parts of the engine. Looking even closer I can see that there is a very slight indentation on the front of the insulation where it touches/rubs a valve cap located near the oil dipstick.

I am curious if anyone else who has this insulation has also installed a turbo heatshield like the NM or similar? The NM has stand-offs that position it just floating above the turbo, but I am concerned about the rubbing, if any, when installed with the insulation.

I know having both insulation and the heatshield is redundant, so you don't need to explain that to me . I just think it cleans up the look of the engine bay and while it was great on my Clubman with NO insulation, having this giant insulation sheet is a concern I have about installing the heatshield on the R58.

Was your car delivered with the under bonnet insulation? Ijust had my 2013 coupe delivered,no insulation. Q

 

Yes I have the full insulation.

 

What is the purpose of that insulation?

 

There is an entire thread about it here:

It's most likely a combination of protecting the hood scoop, paint, and stripes on the bonnet.

In my clubman with no insulation (other than a tiny bit below the scoop) if I drove for an hour and put my hand on the hood, I could burn myself. Now with this full insulation, If I drive all day and put my hand on the hood, it's as cool as any other part of the car.

I have the NM Heatshield and its quite simply the best add on I have bought. The temperature differential after the install was just mindblowing. The only issue I have had was the sensor cable got a slice in it where it touched the shield. Thankfully it was just the plastic coating, I put some electrical tape over it and tucked it out of the way and all is good.

 

MINI never ceases to amaze me. My 2013 Roadster doesn't have the fulll insualtion but does have a heat shield that looks like it is hand fabricated (probably not but it looks that way) from a piece of sheet metal. My hood scoop also has openings in every other vertical row of the plastic honeycomb so it is somewhat functional. Since the Coupe and the Roadster are derivitives of the same model, why would they put full insulation on one but not the other? MINI seems to do this type of thing a lot.

 

I also have the NM heatshield and it works great. Ordered it before my mini even showed up.

 

I have the NM Heatshield. I know how good it is. What I am trying to find out is if anyone has installed it WITH the full under-bonnet insulation. I may have to just install it to see if it clears everything and it doesn't burn the bonnet insulation.

It rubs a little, but no burning to report.

 

Hi Zcast,

Were you able to try this out? I just saw my JCW from the dealer and i also have the full insulation and bought an NM Heat shield before the car arrived:-).

Would appreciate your observations. Thanks!

 

I have not tried this yet. I won't be able to install it for another 2 weeks or so due to being out of town.
