I want to increase my midrange and top-end horsepower by adding a turbo system. I have not seen any aftermarket kits for my engine except the Turbonator, which I have doubts about its performance. I also want an increase in my 70 mph highway mileage. I get about 12 mpg tooling around town and 15 mpg at 70 mph. The best the 5.7 gets is 23 to 24 mpg at 48 mph. If I could increase this by 10 to 15 percent I'd be happy. If anyone has found a company that installs turbos or sells kits, please let me know.

Me and several guys have STS Turbos on our hemi rams.

Check out ststurbo.com

I am a dealer for them.

As I type this, I see hemifever is also viewing this thread, so I expect he will chime in real soon.

 

Ive had real good luck with GSM/PAXTON supercharger and still av 17.5 in the city. Good luck

 

The STS kit is doing me pretty good. BIG increase in power. At 7psi, we go over the 400rwhp mark.

 

@hemifever
Does STS make a kit for 2008 5.7L?
