What did you guys get for mileage before you got your forced induction and after? Also what kind of mods you had on your car before you put your FI on? What type of FI do you have? And my final question how do you drive your car?

 

I got about 17 - 19 mixed driving basically stock. With the STS turbo, I still get about the same mixed. On the highway, I have gotten over 29 a few times which I never did before the turbo. The ONLY mods with the turbo are ported throttle body and LS6 springs.

 

completly stock i consistantly got 25mpg
stock motor, with turbotech t76 kit running 5psi and 42lb svo injectors i consistantly got 23mpg
built motor, 9.0:1 CR, 224/224-114 cam i got 20mpg consistantly

all were getting on it every once in awhile.

 

Before everything with my A4 and 2.73's i got 26-27 mpg on the free way with the cruise set at 80-85........ in the city high teens low 20's.
Stock motor and ATI kit i dont remember but my built 9:1 motor with 60# inj. and my 3.73's with my A4 i get 16-17 on the freeway... and thats all freeway... and in the city... tops 12 mpg and if i play alot... about 7-8 mpg.... so i fill up twice a week...... man im going to love it when the 3 speed goes in If your worried about mpg get a honda for a daily driver and cruise the F-bod on the weekends............. Thank god i got the good ol Camary..

I'm currently throwing an EVAP code so I don't know if that's throwing my MPG off. But what I noticed is putting the D1 on a stock motor I lost very little gas mileage, maybe 2 mpg city/highway. But the 6.0L heads and cam has killed my freakin gas mileage. I made it to about 15 mpg on this last tank and that was a good bit of highway and not much playing around. Makes me sick to think how much gas that cam is costing me.

On a lighter note, damn this car is fun to drive.

should have got a turbo then.
mpg istn bad for me
you cant do to much complaining at 20mpg with over 500rwhp

i think the CR drop effected it the most

 

I picked up 2 mpg city/hwy and 3.5 mpg towing.

 

 

I don't know if it was the turbo or the Nelson tune or both that gave me the increase. But a night at the track i think the gas guage goes as fast as the speedo.

 

I think thats what im going to do. I was actually thinking about a RSX Type-S daily driver (I know but they are fast for a 4 cylinder 210hp 6spd ) and a LS1 for nice days and cruise nights. And also since I want a M6 I dont think it will be to bad on mileage.

Thanks for all of the replys everyone this will give me some ideas of what to do when I get my LS1. Do you get better mileage with a Turbo or a Supercharger? And which do you get more power with?

 

I would say better MPG with a Turbo........
