Steve Hi,
I am sorry I can not provide any before and after measurements but I can
only say that before wrapping the downpipe (from the turbocharger to the
straight side of the exhaust) on my 200Tdi Disco I could not touch the metal
when the engine was operating in the normal temperature range.
After wrapping it with this material (Thermotec) it is possible to touch it
for a few seconds before I start feeling uneasy.
Fellow members of the LR club of Greece that I have persuaded them to wrap
their exhaust headers and downpipes down to and including the Y pipe have
come back to me not angry but thankfull for at last being able to drive
without cooking their legs inside their Defenders.
Another friend who has wrapped the headers, downpipes and Y pipe on his 4.6
engined Discovery series 1 (converted to V8 4.6 from a plain 2.0 Mpi) is
absolutely thrilled with the temperature reduction inside his engine bay.
Take care
Pantelis

Hi Pantelis,
Thanks for the info.
Untouchable, without leaving skin is usually more than 75 deg.

60 -65 degrees-ish - so well worth the investment - Things will be
tight in the 101's engine bay, and you will be sitting NEXT to the
turbocharger.

Not on a landrover, but..
theres a guy here :
http://www.saabcentral.com/forums/showthread.php?t=53206
who i think is about to try some wrap on a saab 900 turbo (to try and
reduce the temperature under the bonnet). He has done some nice before
measurements, so it will be good to see the proper after ones when he
gets it done!
If it makes a decent difference then it looks like it could be worth
considering on a 101.
