I posted a thread last week asking the same question and ppl told me to wrap the engine in foil. Im on tank ten through my new rb engine in my mbx6 and took pals advice to wrap my engine in foil and I drove it in about 40 degree weather and the engine was in the mid 240 degree fairenheit.

My question is, is that okay?

I thought that 240 was too high for my new engine so I took the foil off and it was running around 190 degrees ferenheit. What's better, having my engine at 190 degrees not wrapped in tin foil or 240 degrees wrapped in foil? Or should I just wait for higher temps?
