That's a severe engine test - 50 hours WOT from max torque to max power and back again. Real-world driving will never reach those levels.

Mark told me he monitors cylinder pressure and maps with the O2 sensor on the rear banks, which are more prone to knock.

I'm also careful never to labour the engine at low revs.

Agree. Its the worst case scenario test and your car never hits the tracks so will not see extreme conditions and you should be safe. Matt / Cosworth himself says that there is room for more but we keep it safe for who we are. It is this over engineering and commitment to R&D that I love about Cosworth and their commitment to stand behind engine warranty with their own tune.

If you ever feel like, you are welcome to borrow my Ecutek to datalog and check if you experience knock on your daily drive.

I've just received these bonnet struts from Amazon for the princely sum of £15.55. It took just under a month to arrive, but can't complain.

I'll let you know how it goes.  No instructions except for a couple of photos on the Amazon page!

Well, they work!  Unfortunately, the left-hand one (looking at the engine bay) slightly nadgers the bonnet closed switch, so I have to do some bracket bending.  I'm sure it'll come out fine but I've duck-taped it for the moment to stop the alarm going off.

Photos soon.
