TR6 Transmission tunnel insulation

[EWD]

Any current thoughts on whether to insulate the transmission tunnel on top or underneath? (using one of the heat/sound insulating products) Have seen it done both ways. It would seem that if underneath, it would give you a better top fit for the carpet and padding.
Thanks,
Will

I did sound heat pad then carpet over same. seems to work well I did glue it down and comes off in one piece. On my MG B same and the shift lever cover I used spray foam on inside for heat. Madflyer

Did you still need that Bezel. Madflyer

I used dynamat on top of the tunnel. Works great.

I've used bubble foil insulation underneath the tunnel on both a GT6 and my TR6, with general trim spray adhesive. Doesn't take long, but you have cut a few different pieces to get the whole thing covered obviously. The difference was quite noticeable on the GT6, probably mostly because that car puts out so much undissipated heat to begin with. Didn't make quite such a noticeable difference in the TR6, but the GT6 tunnel was plastic and it's fiberglass on my TR. It seems to me it's done to better effect if done from underneath, but as usual, I have no actual data to buttress this belief, like most things I say. :single_eye:
