I've noticed a lot of you s/c guys are running 42 lb injectors, 90 mm MAF, Big fuel pumps etc. My question is what kind MPG are y'all are getting.

 

Well, I'm not the best to base the numbers off of, seeing as I also tote around 8000#'s of weight when you combine the body, people in it, and accessories on it, but I get between 9.5 and 10 miles to the gallon. (but they are damn fast miles!)

 

That's what I get per gallon. I guess I wil get less than that when I install all my upgrades. That sucks with gas being over $3.00 per gallon, but you know what they say you gotta pay if you wanna play.

 

Honestly, before all the additions, I was only getting about 10-11.

 

In my screw, Lightning swap, #42 injectors, 90mm maf, 12psi, 4.56 gears, 38X15.50R20 toyo's I can get 13mpg on the hwy. I get about 10.5 around town and when romping on it.

Now the Lightning bone stock i got 16+ on the hwy recently and about 14 around town.

 

I got about 14.5 this weekend at the car show. We did alot of sitting in traffic so that's not really accurate. The week before I actually got about 16.5. Not much different than stock. I'm pretty surprised myself

 

Thanks for the feed back guys.

 

The guys who have the upgrades also have the tune to support them. The tune takes advantage of the 93 octane fuel that you run with blowers and advances the timing while in closed loop so, during normal driving, you actually get better mileage. The x-tra mileage most often offsets the higher price of the fuel. You have to purchase 93 octane fuels anyway when you run a blower so this is free mileage.
If you get into it, the mileage drops off significantly but that is a given.
Have fun.

 

I went to Atlanta out-skirts this weekend. I got 18.3 mpg running 80+ and the air on....WOOW. Who knows what I'd get with my foot out of the pedal.

 

^ Nice!
