Turbo or Supercharger

Turbo or Supercharger

Postby Gully07 [OP] » Nov 21 2012, 10:04am

Ok guys I have a 2011 Gmc Sierra and I'm stuck on what to do. Either a supercharger or turbo? Has anybody done either or? And which one would be better and why? And if you have done either or what brand do you go with.

Thanks

Please use caution before modifying as it could void the warranty. Please consult the dealer before adding such modifications.

it will void the warranty. but it makes it fun. but if i was going spend that kind of money id trade in on a 6.2l and have more power and much better mileage with a warranty.

The mileage with a turbo vehicle(as long as you keep the boost within street-able levels) will be much better unless your are constantly thrashing it.
I would go for a turbo, NO DOUBT about it at all.
You could do a rear mounted turbo which requires less spending on headers and exhaust complexity, and your top end power will be much better, and economy won't suffer.
Some may say that there are powerful yet efficient supercharges out there. They are right, go for it if you wanna drop 5k+$
Turbo, in order of importance
Sounds cool
There's a whistle!
Efficient all around
Better town and city mileage by 3-4mpg easy
Cheaper(depending)
More top end power
May be a little lag, but only till maybe 2-2500rpms which could keep from spinning tires
Less stress on engine internals
Andddd the list goes on
It wouldnt surprise me to see you get a 100hp gain from a good rear mounted turbo at around 5-8lbs of boost
And change to a mild camshaft you'll be around 450 at the crank easy
Get some head work done, (port and polish) 475-485 at the crank
BETTER off buying a 6.2l and putting a low pressure turbo and you'll be at 500 at the crank no problem, but that's not the question you asked
So in a word, TURBO
