I just purchased a 2004 5.3 rcsb silverado, and have came across quite a good deal on a magnacharger radix, i believe, its not the tvs series. Anyway i was going to be running 6lb of boost and i am curious as to how many mpgs i should get. Right now i get 17-20 around town wich i am thoroughly impressed with, and i just dont want to kill my mileage for performace being it is my daily driver.

 

As long as you stay out of boost it will be the same. Get into boost, which you will do a good bit at 1st, and your mpg will suck. After you get used to it and drive normal again, you will be back to normal mpg.

 

+1

With my TVS1900 mileage stayed the same, I think I lost like 10-15 miles per tank IF I drive normal.

A radix shouldn't be that far off I'd guess

 

If you drive the same it will stay the same for the most part, when you put the pedal down it is going to use more fuel but it will pull allot harder also. Highway should be pretty much be unchanged, you may notice a small drop in city mileage depending on how heavy your foot is.

 

Hey David, guess whose Radix he's looking at.?.

 

Not here to thread jack but what happen to the radix? They used to be plentiful in the classified section a year or 2 ago? Now there hard to come by used

 

Cool. What is the next plan?

 

Umm, they came out with the TVS and now its more popular.
