RE: Bottom End Performance Mods
Bob is right! UDAMAN Bob!
I think we should call him Turbo BOB. No but really he is right. I am
thinking of first generation Turbo's. If you have a choice I think that
Superchargers are the way to go. I have had both.

Depends on size of turbo and what rpm it's designed to kickin at.
The 1.8T engine is a low boost turbo that comes on at very low speed.
This gives the engine a broader power curve, however, it's not as strong
as higher boost turbos.

Turbos run off the exhaust and supercharger run off the engine.

There's a little confusion here gentlemen, the intercooler merely cools the
air coming into the turbo, it has nothing to do with cooling the turbo
itself. If you have a turbo a cool down idle or just driving slower before
you shut down is a good idea to prevent coking of the bearings and release
some of the thermal loading. However, most turbos today will utilize
synthetic oils to prevent this and will have a water jacket with an
auxillary pump and thermostat, which will run after the engine is shut
down.
