Ok so I've gotten the tax return and thinking about going FI, but my Z is a DD. I was wondering for those that have stock blocks, what kind of MPG are you getting with 8-10psi. I want more power but I just want to know how much of the practical side of my car I'll be losing (MPG). Right now I'm getting a good average of 24.6mpg between HW/City. LOL Flame on if you want to .

 

when I was boosting 10-14MPG average. not boosting 30+ MPG

 

I do very well on the highway 25+ mpg and around 10-12 under boost

Several F/I members posted in here IIRC.

 

^ Thanks... I didn't know where to look. It's the noob in me

 

^^ actually this is just posting gas milage for those with NA motors or guys that just got their Z. I'm looking for MPG after the boost. Thanks though.

 

My bad - I thought there was a F/I thread like this last fall, but I can't find it now.

 

i don't know....my car wasn't boosted

I even searched Cannysage, I thought that was who started the thread. Thanks Tom.

 

^^ Thanks a million... My searches yielded nothing... maybe I was using the wrong keywords

 

I have madd search skills

MPG (title only), 350z FI section.......holla

 

Thanks Tom!!!! You're a search god... lol

 

Same here..

 

In general not that much if you aren't boosting, but a lot if you are boosting. Again it's all about how you drive the car. However, if you are concerned about gas milage, you can't afford to go FI

 

If you believe the "vacuum" mpg gauge in the nav on the G's then I get 40+mpg when in boost hehehehehehe

tom

 

No boost=about 370 miles to the tank...boosting= about 285 miles to the tank...which is usually about 15 gallons every fill up before the damn light comes on.

 

I have no idea, my MPG gauge says something like 40-50+ but my guess is when out of boost, maybe 30 or so thanks to the 3.3 rear end, however in boost, god only knows.
10-12? lol

 

damn I thought mine was bad High way 30-40 on 10 psi street 15-25 Im always on high gear. 35mph on 5th or six 15 on 2nd or 3rdgear

 

25 out of boost 12 in boost.
