Turbo is hot..and red, does this happen to you Options

[DSM5]

Ok, my friend has a Starion (i know tis not a DSM but its still turbo) and it gets RED HOT! like glowing. I told him it was normal. Does this happen to you guys also?

Think of it this way. A lean condition creates more than normal heat from the point of the chemical reaction. That heat has to travel out of the combustion chamber because of the natural equalization of pressure in the atmosphere. Now, when you run a higher octane fuel (on any gasoline engine) you have the ability to run a more advanced intake timing to make more power. Try running a timing curve set for 100 octane fuel while using 87 octane fuel. The engine will run lean and you will see much the same results. The stock timing on a turbo car is set up for 92/94 octane fuel and if you run 87 through it the results will be similar as well. Retarding the timing on the intake cam will "slow" the time between when the intake valve closes and when the exhaust valve opens. This offers a more gasoline efficient, safer, richer mixture because the reaction has more time to burn all the available fuel. Running a higher octane fuel compensates for it in this situation. Or.... as Larz said, this could be the result of an incredibly restrictive exhaust.
