What kind of gas mileage can i expect from a supercharged 350 TPI engine? I'm getting ready to build a 350 for my daily driver and dont know if N/A or Forced induction would be best for performance and mileage. Also if i go FI, what kind of set up would be best? and what kind of supercharger would you recommend? Thanks

 

A supercharger wont change your gas milage as much as you think, as long as you can keep your foot out of the gas.....

Thats why I like the idea of a supercharger, just cruzing you can have a decent idle and great highway cruzing, but get on the gas and she comes to life!

 

i would go ahead and spend the money on an ATI you can always do upgrades on the D-1 and you can keep it low boost for driving around on the street

also i would get the twin highflow intercooler system that they have because it is only a positive factor if you want to go bigger someday

and believe me if you are all about going fast once you go 12s you want 11s and once you go 11s you want 10s and so on and so forth but people on here will give you some good ideas

 

Cool thanks for the info! With a setup like this should i go with stock type pistons crank and such? or so i find some nice low comp pistons?

 

Depends on how much boost you want to run, but it's alway's a good idea to change to some nice forged pistons.

And I get about 22 mpg with mine

 

I am also getting 22mpg highway with mine

 

from the last 2 posts alone you can see,

383 supercharged...................22mpg
305 supercharged...................22mpg
My non supercharged 350 .....23mpg

my car is 100% stock
