Expected MPG?

[Rated R]

Read somewhere that the supercharger has a bypass to allows for better mpg when you're not using the power.

I think all factory twin screw superchargers have the bypass valve. TRX/Hellcat and the GT500/R have them.

I guess that answers that question 10 mpg city - 15 mpg highway.

That sticker makes the TRX seem like a pretty good bargain.

Pretty nuts they're removing the heated steering wheel on these. Top of the line truck and they're removing options still....

It depends on where you live too. I’m in WV so I wouldn’t expect more than 14.

I wonder if the boost bypass valve on mine is not working. I couldn’t get better than 12 on the highway on flat fl roads

I just got 15 on a 3 hour highway trip. I have been getting around 9.5 in the city.
