In last summers heat wave I went up a local hill in our RN which takes about 5 minutes in bottom gear and only got halfway up before it gave up whilst our other RN had no problems, both have standard engines and 22 FZB carburettors. I opened the bonnet and it was like an oven inside and I could hear the petrol bubbling in the float chamber, whilst waiting for things to cool down I realised that this car had the plate under the exhaust between the engine bay side and chassis and I knew the other didn't have this plate. So it was promptly removed and proceeded on my way with no more problems. On the RP cars this plate goes over the exhaust.
