Oliver,
You are a gentleman and a scholar sir! You will need something that goes
up to 180 deg F - I think! So an oven whatsist should be okay. Duct tape
will stick it. Run the car on the road for 15 minutes to get to working
temp then whip bonnet(hood) open and record temp. Close bonnet and wait
3-5 mins then read again. If you send me your address I will send you a
piece of soundproofing that I am working on to see if it sticks under the
max heat reached under the hood!!
