Turbo and injectors improve mileage!


Recommended Posts

The new HX turbo and 275 injectors look like they have improved my mileage by 2-3 mpg on my work run for the week. That will save me about $700 a year in fuel. Plus the added performance for towing. So it's not all about going fast. Next I'd like to do a Smarty.

So you just replaced the factory turbo w another?  Are those the RV 275's?

Nice! Would I pick up and fuel economy by going with a 4" exhaust and Diamond Eye muffler?

Actually no. Because if you truly running for MPG's you boost should be below 5 PSI if so there is no flowing exhaust really (Back pressure). I'm still running 3" exhaust just straight piped and no issues at all with MPG's.

 

Actually you find slightly warmer intake air temps promote better MPGs more than anything. Between 100-140*F you'll get you better MPG than colder air will.
