Dynamat - Does it help?

[gvickery]

Anyone used Dynamat in an attempt to insuluate cabin heat, just a bit - especially for the "passenger"?

I drove the MKII to the Schloss Dyck event in Germany a couple of weeks ago when on the outbound leg we ran into 38C+(100F) right into the evening. Now I know that is twice the average high summer temperatures in Blighty and come to that 100F is probably the max ever experienced in the UK, so yes - this trip was exceptional. Or was it as during the 2010 Le Mans Classic we were zapped with greater temps still! Thankfully, water temperature hardly budged above the norm due to the Tiger being bog standard but the heat & heat soak was total++!

STOC Tigers driving in Europe is on the increase and whilst my being cooked is one price of Tigering I can accept, the lady of the house will not!! So if I am to persuade her to navigate me to Cannes / Monte Carlo on the 2014 Monte Tour I need to do something about cabin heat on her side!!

Dynamatting the passenger foot well, the rear floor, tunnel and up the firewall could at least slow heat up and even keep it down??
Then there is the wild step up to fit a heat shield(s) between the floor and exhaust run!

Looks like.


This could be too much!


Wild measure - floor exhaust / shield


I'm looking for this!!


Not this!!


So what's 'team thinking'?

I've looked into this as well although our Tiger doesn't seem to be that hot inside, we didn't suffer unduly on our run to and from Schloss Dyck.

My only concern with Dynamat is that it's stuck to the floor, what happens if you ever you need to do any welding underneath. There is also another similar product made by Eastwood which is a bit cheaper.

I mainly considered it for the sound deadening properties.

I recently had laminate flooring put into an upstairs flat I rent out, to cut down on the noise the flooring company fitted a sound deadening underlay which had aluminium foil on one side. Although expensive for flooring it would work out much less than Dynamat and may do the same job. I've had an offcut under my drivers mat for a while and it seems to work OK. I'll get back with the make and price.

I used Dynamat on the floor and firewall of my Tiger. I then used Dynaliner over the top on the firewall. The Dynaliner is better at stopping the heat and Dynamat vibration and sound. There is no heat being transferred into the car.

I put Cool Tec foil backed material in my foot wells, which is very similar to Dynamat, it does work, I was at Le Mans Classic in 2010! I did not bother with the tunnel.

Simple, just leave the car alone & the wife at home. Works for me!

Do exhaust coatings like zircotec work? if so, you may not need all that extra insulation.

Anybody have experience installing air con into the Tiger?

There must be now a simple kit you can plug in?

I cam across this today, ultra thin head shield material. You can even get it with gold coatings if you fancy some bling

Anyone done a cost and performance comparison of the various solutions ? I don't want to be scrambling to do this last minute, and while I've got half the carpet up to fit the MX5 seats, might as well tackle heat insulation.

Any recommendations on the easiest way to remove the original horsehair / tarmac sound deadening material on the floorpan ? Horrible stuff...

[alpine5gt]

Yes, remove the origional felt/horshair with lots of elbow work and carefull use of a power sander. My floors are now painted metal waitiing for the heatshield sheets. Yes, the MX5 seats have been retrimmed waiting for fitting.
