These pictures were taken within seconds of each other from the same perspective. The one on the left was taken with a flash the other obviously without. You can even see manifold glowing in the picture on the left. These photos were taken after a late evening high boost(24 psi) run up Teton Pass(10% grades about 7.5 miles). Sustained 24 psi up 10% grades 100 mph+ between switch backs going from 6000ft to 8600ft. I'm sure alot of you guys with track time have seen your turbos glow even brighter than this. The downpipe was glowing all the way to the bottom of the car, it is amazing to see, you think something ought to melt. I hope everyone out there is using Synthetic oil.
