I drive a 2006 rev-up and before the vortech install I was lucky to get 19mpg doing 70 on the highway. Now I have 380whp and I do 40mpg, is my mileage calculator screwy or is that really possible?

 

your mpg calc's wrong. it was wrong before your sc install, too.

calc it on your own. : ]

 

hahaha yeah right.

1. fill up gas tank
2. reset odometer
3. use up gas tank
4. divide new gallons

 

Technically it could be, if you drive it slower and less aggressive now than you did before the install.

But thats not likely.

 

Ever since I pit my vortech on my 03 I get around 30 more miles on a full tank. It's weird and I even get on it . Idk lol

 

The mileage calculator is wrong...the problem is that the calculator is based on the stock injectors, so when you put bigger injectors it does not compensate...

And unfortunately you can't re-calibrate the mileage calulator to your new injectors, at least you couldn't when I asked a long time ago...

 

There's some variables that make this hard to determine.

 

Just me or does this not make sense? I would think the bigger injectors it would read more fuel flowing through resulting in a lower gas milage not higher..?

Correct me if I'm wrong

 

I have the vortech and get 418 rwhp. My mileage hasn't really changed much, I was getting 26.5 to 27.2 on the road with N/A add ons, i.e. headers, catback, and cold air intake, which was a improvement to the original stock. Now with the vortech, when I get on it then it will naturally go done (i.e. 23.5 - 24). I really don't get on it much though, only when somebody tries to cut me off instead of getting behind me, etc. I like just driving the normal and having the extra the unexpected or showoffs. I use cruise lot and I get pretty much the same, and that is a little over 25 on the road.

 

Supercharger is parasitic which means your mileage goes down.

The stock ecu thinks you are running the stock injectors on smaller pulse widths which is not the case. You are running larger injectors which flow more at the same pulse widths.

 

what was nissan thinking ---- it could double gas mileage and get 60% more power by slapping a supercharger on ......... when will it ever learn

 

Finally. Someone who understands.

You don't know how many people I have spoken with talk about how crappy their MPG's are. How much it sucks to fill up 60$. Yet still, they don't know what their talking about more than half the time.
Who cares if it's 60$ a week in gas when that 60$ will get you 15 gallons to drive 500miles. Fuhhh. That's more than 30mpgs.

 

Increase horsepower
Maintain same vehicle weight
and MPG improves? Impossible.

 

FTFY. Superchargers are not weightless like turbochargers

 

Did you reset your gauge and you're still getting this reading?

Something is not adding up..

 

I gave up on trying to correct those people. They don't want to understand math...so they don't.

 

My MPG gauge reads 30mpg all the time.

I'm twin turbo, and my highest number by doing the actual math was 18mpg

Don't trust the gauge.

 

Who cares about mpg's. If you you want mileage get a prius.

 

the gauge is is wrong mine says 31mpg. i average 18mpg and its mostly highway gtm sc @ 12psi 440 whp

 

I don't go by the gauge, i go by how much fuel i've used over a given distance.

That being said, the last time to the track I averaged 29mpg including the 3 runs at the Strip....... Mostly highway on cruise control @ 75mph.

Believe me, don't believe me.... I'm not one with bad mpg's

I feel for you guys that get crappy gas milage, you don't have to.......
