New Bronco Seems To Confirm What We Suspected

I feel like I've stumbled onto a BMW forum...

you could also link your sources.
so until you do, i'll just be as lazy as you.
i read plenty. some are bullshit as i alluded to earlier, like tuner companies, pushing their tunes....as well as many others who say HP gains are negligible, which is my argument.
The Bronco didnt just gain all this HP cuz the tank was filled with higher octane fuel. theres much more to it than that. or did you need a hyperlink for that??
if i linked everything i read, you'd just see a ton of hyperlinks, and i know you're too pompous to even read them, so why bother?
so here we are, bickering about sources now.
You might think I am juvenile, but look at the bulk of the posters here....I'm no different.

I've enjoyed reading this crazy thread... Here is my contribution to thie s--- show. @RANGER PRIDE - you say that octane alone does not add power. That would be a technically correct statement. That being said, most modern vehicles, especially a turbo, is smart enough to adjust the tune when it recognizes the higher octane fuel. Adjusting the tune is what gives you more power. Higher octane fuel allows the truck to change the tune to accommodate more power. Tuning does give you more power. Ford is limited to tons of regulation around fuel and emissions. I would be Ford recommends 87 because the truck runs great and it helps to lower the annual fuel costs listed on the window sticker. My sticker said I could expect to spend $1450 annually with 87. That cost would jump to $2000 annually if I ran 91. Would the truck make more power on 91? Yes. Would I notice it? Maybe. Do I want the added cost? Nope.

Your comment about biased information from tuning companies is correct. They are showing you the 'perfect condition' results. I can not and would not argue you on that point. I have no doubt believing that the Ranger/Bronco will make more power on higher octane fuel. I would be interested in seeing the stock 87/stock 91 dyno runs though. I will have to look in to that. I would bet it takes a few tanks of 91 to see real gains in power. A knock sensor detects pre-ignition of the fuel and advances/retards timing to make sure that you aren't risking your engine. Timing helps make/reduce power.

Hi CR,

Auto Manufacturers and the US government run at Standard Test Conditions. These conditions include Temperature and Barometric pressure....something Joe's Dyno likely cannot do unless he has an air lock that fits a vehicle and a huge HVAC control for the dyno room. So to a degree it is hard to compare results from tunes including the same tune on different days...Thus take the Tune numbers with a grain of salt...

Several manufacturers run adds bosting about their HP an TQ numbers. Many times they have an * next to them. When you look at the footnote for the * it says "when using premium fuel.

 

[VAMike]

as well as many others who say HP gains are negligible, which is my argument.

So now you're changed your argument from "tell me more, how does octane change power output" to "octane does change power output but I don't consider the change to be significant". That's a much more reasonable and less trollish position, glad you're finally on board.

 

[TBR17]

Well, instead of juvenile trolling you could actually do some research. The effect of octane on spontaneous/preignition, and the timing adjustments to compensate, and the effect that has on engine power output are all fairly well documented in peer reviewed literature. Will more octane automatically give you more power? No. Will more octane give you more power if your engine has retarded timing due to preignition of lower octane fuel (particularly in a turbocharged gasoline engine)? Yes. (That is, in fact, why octane is added to fuel: to make it harder to ignite.) Will the amount of power you gain be noticeable? Maybe, maybe not.

If you want to be more than just a ridiculous troll, try presenting a respectable contrary source, which indicates that octane does not have an effect on engine power in a GTDI engine. Given some credible contrary data we could discuss the particulars in more detail.

hahahaha...you said, retarded.

I settled it all (as far as I am concerned) and ordered the Ford Performance tune. My local dealer says they will do it for $112.00. As I am 73, I'm going to try real hard to keep my license.

How did you get them to do it so inexpensively??

It was what they quoted when I contacted them to make sure they could install it. I had no reason to complain.

Maybe I misunderstood.. the cost of the tune is separate isn't it. This was just the install?

Yes, just the install. I purchased the "tune" from Levittown Ford.

I bet Dave's online ordering one right now... ?

I just walked in from vacation and you're already costing me more money! ?
