The effects of proper lubrication and cooling. And most importantly proper maintenance. Please tell me why the 4.0 is so darn noisy!

Usually it goes away after 30-45 seconds. In addition, at this age they often develop exhaust leaks and cracks in the exhaust manifold, which will definitely add a lot of noise.
