so my biggest dilemma is i just picked up an 04 z for a daily due to my avalanche sucking down gas. my z has some mods... hks hi power ti, 5/16 plenum and nismo cai... but i want more power. so my question to u turbo z owners is how is ur mpg (not romping) is on day to day driving.

thanks

 

you want power and gas mileage??? have you heard of a motorcycle???

 

you mean the yamaha champions limited edition r1 sitting in my garage.... yes i have.... no need for sarcasm buddy just asking what the mpg is like... but thanks for the post any ways....

 

so now im going to have to rephrase what im looking for due to the glass half empty bored to tears negative nancies out there..... FOR THE PEOPLE WHO HAVE A TURBO CHARGED 350Z...... what kind of numbers are we looking at.... is it still worth it as a d/d.... or just stay n/a?

thank you

 

32 mpg on high way avg speed 75 on e85. Close to nothing when I put my foot in it.

 

thanks bro now thats helpfull lol i understand theres going to be some foot to the ground driving.... but im not looking to beat it lol just thinking like 8 pounds have a lil bit more fun when i want it .... but normal driving for the most part... just seeing how it effects normal driving...

 

hey jay here i got the greddy twin turbo set up and i avg about 24 miles per gal. i have seen about 27miles per gal but lately i seem to be having a lead foot lol

 

im not exactly sure how accurate my car is anymore with all the stuff done to it but on the ride home from Denver i got over 300 miles to a tank on e85.

 

Should be similar to stock until you are pushing it. Turbos are not like superchargers generally speaking.

 

thanks guys this is the info i was looking for... and yes i thought about supercharging it but ive heard some not so good things ..... so i think ill stick to the turbo...

 

If I had a question abut forced-induction I would ask in the forced-induction forum but thats just me.

 

i only get like 19 and im not boosted

 

davidv thanks for the input..... again new to this site..... but ill keep that in mind for next time...

 

That's more like 15mpg not 30. As soon as you change the fuel system in the car you can't use the displayed MPG from the ecu. It's wildly inaccurate. You have to fill the tank and continue to pump until you see the gas in the fill neck. Drive it until you are really low then fill until you see the fuel in the fill neck again and divide miles driven by gallons. that is an accurate average mpg. You can't use the point at which the pump handle kicks off in order to fill your tank because each pump handle has a different sensitivity to pressures.

In theory you will lose a little power due to the drag from a supercharger but average per tank i was mid 20's on my vortech at 507hp and when i tuned my turbo setup to 652 hp i still remained mid 20's. That was conservative driving on a daily basis. Driving short distances to and from campus and the gym i would get high teens or low 20's per tank. There really wasn't much difference between the supercharger or turbo if i was just normal driving.

Here is the problem though. You said you want more power. So if you add more power you aren't going to drive it how you did before you will drive it harder. People think that they don't but in truth if you have power on reserve they use it. So expect your mpg to be lower than what you have now because I will bet my life that a person wanting more power can't drive the car for an entire tank of fuel without getting hard on it.

 

I do not understand why a person would spend $10k to turbo a Z (properly with clutch/exhaust upgrades assuming a shop is installing and tuning it all)then worry about fuel economy. If you have the power then use it, otherwise keep it stock and enjoy it.

 

turbo + DD = stupid

You should be stopped there, before the ridiculous MPG question even comes into the picture.

 

My Turbo Build will be a daily driver, but I also own a 09 Yamaha R6. So I dont really care that much. Low 20s would be fine for me.

 

So what do you do when your turbo Z is broken and its pouring out?

Cool guy on R6 in the rain lol

 

you laugh but i cant tell you how many people i see riding sports bikes in the rain on island >.< granted it rains all the time here and randomly most of the time still shiny out with white clouds

 

slap on a turbonator and call it a day.
