2012 Mustang Roush Six Success
 
I was always updating my new member page, but I will switch to here. I am at work on a break, but have to say ob my 10 mile commute, usual averaging 35 mpg, my all time high was 43.x, today I hit 48.0 mpg.

I am ecstatic about the result, and am filling up tonight. Later on I will expand on the new changes, but I want to do some research before I put together information on results.

Must know more!!!!!!!!! :thumbup:

I am going out to test today where I got my baseline mpg/speed charts before. I now have a rear valance, which I doubt does anything, and cold air induction. I do not expect cold air to benefit me, but the cone intake compared to the little mail flap opening should make a difference, whether good or bad.

As of right now I have no conclusive evidence, other than my crazy to work mileage, and my return home mileage being 30+ when O could barely hot 30 before.

I have running around tondo, and then I can get testing done today.

WOW good driving ! that is some fantastic mileage you achieved, 35 mpg is a ground breaking (for your car) mpg average.
Good to see technology has advanced enough to average that kind of mileage, with your driving techniques.

What are the hp/torque numbers of the car ?

PrePin 10-08-2012 12:55 PM

One Roush associate who is more on the business end says the axle backs and cold air induction equal 50 horsepower, but I personally have a hard time believing that, especially without a tune. WITH a tune, one would normally expect 15-25 hp from axle backs and CAI. Results vary depending on tune, and equipment.

Without a tune, I would anticipate roughly ten hp out of the two.

I am working on a new lower grill block for the coming months, I should be finished tonight with it.

Spd-Old--New
44-56.5--49.2
54-49.65-46.2
64-41.45-41.45
74-38.6--34.55

New Results North/South-score
44-52/46.4-49.2
54-47.6/44.8-46.2
64-45.4/37.5-41.45
74-37.1/32-34.55
*Start time 10:46, end time roughly 11:05. Start temperature 46 degrees F, end 48 degrees.

Old Results South/North-score
44-45.8/67.2-56.5
54-42.5/56.8-49.65
64-36.3/46.6-41.45+ A/C was on
74-34/43.2-38.6
*Start time 12:10, end time 12:46. Temperature was 87-90 degrees F, which was why we had the A/C on, and we forgot about it during the 64 mph run.

I am glad I made these numbers before, so I had a reference, because clearly from testing there is not a positive change. Please note that all of these were done one time, not multiple runs, and during the day (both on Mondays), so traffic was around, but not strong. I must also note, that while driving on the highway at 44 mph, in a 65 mph zone with cars doing 70+, so air resistance may vary.

I am thinking that my results presented by scanguage and car may not be accurate, and that the SGii may need a few fill ups before it returns to past accuracy. I have noticed differences in SC results, and car mpg estimates to actual results. I have started logging those in with my fill up data.

But either way, as long as I keep 30+ mpg per tank, I will be happy, especially rated for 29 mpg highway. I know mpg will drop with the coming winter, and putting on snow tires in the coming weeks. The belly pan will begin preparation soon, and I am most likely going to lower it when I switch to the 2014 Mustang GT OEM rims and tires come March/April of 2013.

Also, this is UltArc on my wife (PrePin)s computer.

I clocked in my most recent tank.

37+ mpg. Mind. Blown.

Premium fuel, EOC, warm weather.

Beautiful.

Updating my fuel log now.

That's crazy. what kind of power is that thing putting out?

Are you still having fun driving it?

UltArc 05-05-2013 06:05 PM

Usually the standards put about 270 ish to the wheels, I have CAI and axle backs, without a tune, that is maybe five hp to the wheels. I would tune - it helps power and efficiency, but I got the 6 year warranty- so if anything happens, it's covered- and a tune may ruin that.

I have a blast. The biggest thing is my EOC, I believe. Last year I had similar weather, and not as good of fuel economy- but the tires were less worn in, I dealt with different traffic flow, and was not as experienced.

I need to find a lift, and redo my underbody. It was fantastic while it lasted...but the energy it took to get it on blocks is too much for me alone, again. My current project is a lower grille block.

UltArc 05-10-2013 02:03 AM

Tonight I finished the lower grille block.

It takes approximately 25 minutes WITHOUT a lower grille block and 85+ degrees F external temperature, to reach 200 degrees F water temp- and it won't go past 203.

After completion, I took it for a test drive.

I did not do ABA testing. I found at 61 degrees F, it took approximately 16 minutes to reach 200, and by 25 minutes was at 214. I also found the fuel economy was better than ever before with the engine on. I am not sure how much aero has helped, although I noticed my normal coast points forced me to use te brakes (usually I end up at the speed I need for lower speed zones- today I had to brake and slow down to not be speeding). I am more so thinking the increase in FE is because of a warmer engine bay.

It SEEMED that I was getting better fuel economy, but to be clear, there is no real set data. The setup I put on isn't friendly to take on and off, so I doubt it will happen. My only concern is what the top temp I should let the car get to before removing portions of the grille block. Hopefully, I can just remove the little side pieces to maintain a temperature-if I am forced to. I would rather not have to adapt it at all.

Have you thought of calling Roush? they optimize most of engine systems in stage 3 & 4 cars. They would tell you exactly how much block and such to install. Thier not going to give ya bogus info.
