I have seen many posts about turbo charging one of these. Just thought I would start my own thread.
The theory of turbo charging is to increase the engines power output by sacrificing MPG dramatically when in need. I am not against this for short demands up to 15 seconds at a time.
Many 4 cylinder cars with turbo outperform their V6 counterparts in both horsepower and fuel efficiency. Why is this? A car designed with a N/A engine has a larger displacement and more fuel guzzling characteristics to have the on demand power for pulling out from a red light, pulling on to a highway, or passing. Basically all the actions needed while driving except maintaining speed on the highway.
Most turbo charged cars have the engine size optimize for fuel efficiency at maintaining highway cruzing speeds. This means a smaller, lighter, and more fuel efficient engine with some extra power on call when needed.
Pros and cons of turbo.
Pros:
More power as needed.
Better overall fuel economy when used properly.
Smaller engine size needed = less weight.
Cons:
Higher pressures needed cause stress on head gaskets, bearings, etc.
If engine not designed for added stress = short life expectancy.
Extra components needed from factory as an option can range from $500 to $1500 "my estimate for the engine size."
Turbos require a cool down period before turning of the engine.
I should explain the last con further. Most people with turbos break them for this reason. The turbo when running has the flames from the exhaust running directly inside them. They require an oil supply for the bearings they spin on. When run hard they can get red hot. If the engine gets shut off while the turbo is hot ( Just recently provided boost ) The oil supply stops that cools the bearings. The oil on a red hot turbo then burns onto the parts seizing them up.
Turbo owners let them cool off at idle for at least 30 seconds every time you park before turning off the engine.
