I want to pick your brain about this, oil pan. I know what I am going to ask is a bit off this topic.

So by increasing boost you get lower exhaust temps? You mentioned in another thread that you got something like 3 psi at 60 mph and that gives you several hundred degrees less exhaust manifold temps? How does that work. Besides measuring it do you have a theory about it?

Before I turboed I saw EGTs in the 1000'F to 1100'F all the time, now they rarely go above 800'F and normally stay between 400'F and 600'F.
These are all preturbine temperatures too.
