My best is 25.8 ... 5.0, Procharged, 3.55 gear cruising at 75 mph from Kansas City to Illinois

600 + HP , on 22's , and glad I didn't get a Eco-boost !

I think I get around 15/16 in my little 4.6L with 3.55's and 23" wheels. And that only has a third of your power!

Very nice truck!

 

That is just amazing!

 

 

Merged two threads, one thread per subject please.

 

You Build or buy that sexy beast bro..? i know the wheels aren't factory, but thats about all I know about the newer trucks... From about 03-04 and back, i can build and rebuild with my eyes shut, but anything newer and im a button buck at best... lol.. that engine looks sooooo sick, would love to take that motor and put it in my S`crew.. thanks again for prdoning the ignorance... and SWEET TRUCK.. sorry, had to say it again... only thing about that truck i would even dream of changing, would be some slick side skirts.. Kinda looks like a raked truck with a body lift. Just a little outside looking in kinda thing. Man that truck is sexy tho..lol
Keep on Truckin'

 

Sweet truck, but I am partial to black trucks to begin with. I would love one of those engines in my truck also instead of the 4.6 mouse motor in mine.

 

Looking good and awesome mpgs...

 

You need one on yer truck too...

 

Doesn't that kit use bigger injectors so that any reported MPG by the computer are incorrect as they are computed based on duty cycle of the injectors and obviously for the same duty cycle bigger injectors use more gas? I know that is how it was on my supercharged BMW's.

 

It's a sexy powerful truck for sure but the mpg's is bogus. The mpg's on the trucks is 18-23 to begin with. It doesn't magically improve 2-3mpg with a supercharger and heavier wheels.

 

If you'd stay out of boost I can believe it. Lowering is documented to improve MPG, Long tubes, and tune would net higher MPGs. I'm sure the boss intake doesn't hurt either

Ive already seen (and calculated) 23.8 crusing at 60 mph in my stock 5.0

 

It makes decent power but the mpg is far from Bogus... For starters, I wouldn't start a thread to misrepresent myself or my build. It's funny, some people are quick to make a opinion without even asking crucial info ..it's very clear that Bluejay knows what he is talking about. My truck cruises at highway speeds with almost 20lbs of vacuum. Centrifugal blowers are easier to stay outta boost and as a result, the fuel pressure doesn't spike as often. Then take in consideration the truck has a 6 gear transmission with a 3.55 gear can make a impact.

The reason I was going to Illinois was to meet the soon to be new owner of the truck and my wife followed me in our expedition with a 3v. We both gassed up at same time, followed each other, and by time we got to st Louis.... I had burned up almost half of what she did, literally. I'm not sure if that was a good example to compare because I'm not sure what the difference in size of fuel tanks are. I do know the expedition got horrible gas mileage when we picked up the boat though lol...

Too bad I feel like I need to be defensive when I know my claims are factual not bogus

 

Not accusing you of starting a bogus thread. I feel like the reading on your dash is bogus. Again it's a gorgeous truck and a great build. I love your truck. I'm not attacking you. For what it's worth cruising with vacuum is done with any blower lol. Unless of course you disconnect the vacuum bypass. That's what the bypass is for. To prevent the blower from boost unless a load is placed on the motor that changes vacuum to zero.

I disagree with the long tubes and intake helping mpg's. I'm sure someone has done a test to prove it and others have disproven it. It were true the trucks would have long tubes from the factory as they are under tremendous pressure to improve mpg's by both the government and the buying public. Lowering can help but only so much. Large heavy wheels will cost you mpg's as the rotating mass becomes so great.

Perhaps you are getting the fantastic mpg's perhaps not. Right now it appears the only thing you are going on is the dash read out. Again not knocking you or your truck. You have to expect some skeptics when posting information of this nature. Either way you have a truck to be proud of.
