How different Turbos work
Hi Everyone,
It was a slow day at work today and I was on stumbleupon.com and came across an interesting article on turbochargers. It covers the different types of turbocharges and the various setups for 4,6, and 8 cylinder engines. I knew the Mini Cooper S came with a Twin-Scroll Turbo but I was not sure how it worked until after reading this. If you have the time, check it out:

Hey, this is interesting. That original link started on page 3. Go back and look at page 2 and you'll see why the hood scoop on the Mini isn't functional.
Today, intercooler is virtually standard on all turbocharged cars. They are usually mounted behind the front bumper intakes to take advantage of cold air. Some older cars have intercoolers installed above the engine and breath through a bonnet-mounted scoop. However, such designs are no longer possible as new pedestrian safety regulations in Europe require more clearance between the engine and bonnet. The only exception is Subaru's boxer engine as it is inherently low enough.

The scoop is not open because it no longer directly feeds a specific part such as heat exchanger or intercooler, but opening it up is still a great idea for allowing airflow over the engine to help move the hot stagnant air that can soak the intake tract and also cause your hood scoop to warp from all the heat coming off the turbo's hot side and having nowhere to go.

Mini doesn't need it and there was talk of not having it on the F series, but people like the look.
The Goodwood doesn't have it and I think it looks fine. I am not a fan of fake stuff on my car. The only thing the CM has that bothers me are those fake ducts behind the rear wheels, but they are pretty small.

Fake or not, once you open it up, it serves a nice function. A turbo produces a ton of heat, let alone the heat the engine does on it's own. Letting some air flow over really brings engine bay temps down.
As for rain, it's very minimal what gets in, and honestly, there's NOTHING a little rain can hit under the hood to do any damage to anything at all. I drilled out my stock honeycomb, so there's nothing large getting in either way.
