Economy of boost
OK, more like economy with boost, here are my less-than-scientific observations (each time I get gas I fill up and reset the trip meter):
My stock greddy system would routinely give me around 27 mpg at wastegate 5.5 psi. My greddy system with a BEGi FMU in place of the vortec 12:1 gave me 26 mpg at 6 psi and 24 mpg at 9 psi. My greddy system with a retuned double check valve BEGi FMU gives me 27 mpg at 9-10 psi. |
hmmm miata 1.8 n/a miata would struggle to get 20mpg...U drive like an old lady lol :P
edit: whats this double check valve business? |
i see anywhere from 25-27 with the system the same. However i'm sure you noticed a difference now as you leaned it out from before.

I certainly don't get that will all in town driving. Sometimes if I do a great deal of highway I have seen some pretty high numbers, if fact almost 30 once, but usually with a mix I get between 20 and 22.

my gas mileage really didn't change all that much with the turbo. Still average 24-25mpg easily while beating on the car.
|
I consistently get 30mpg back and forth from tampa to tallahassee, cruising about 65-75mph.
|
24mpg, all city or hard driving on tennessee backroads. I'm pleased.
|
i need dyno time. I'm getting less than 15mpg on average. :eek:
|
my car is messed up. 1.8 n/a no mods and I get........ 17-18mpg (city)!! :eek:
and around 30mpg cruising 75-80mph! wonder what it's going to be on the new built engine and than + turbo, |
Other than being loud and annoying NA...you guys see a test pipe giving any help to MPG?

You were driving less than a mile to school every day?! :bigtu:
Good way to shorten the lifespan of many parts on your car. You should've bought a Segway...or WALKED.:gay: |
i drive around 5 miles each way to school. and than around 8 miles each way to work. it gets hot after a mile or so.
