2012 Mustang Roush Six Success

Their grille is actually made to help get air into the engine bay...both are wider and let more air flow in- one of the reasons I wanted the GT upper instead of the Roush.

I have the last Roush fabricated bumper (not the very last one made, but the last mass Roush vehicle produced one).

I am not too familiar with RS4s, I have never heard of that before. Is that something new in the pipeline? Last time I was there, when I went into the bay with the guys, they had to cover something up and asked me not to take photos of it (I take 300-500 photos each visit lol). Could this have been the RS4?

This last tank was 37.3+ mpg. So, my fear of the past tank being a fluke is unfounded.

I am thinking about so many moments that fuel was wasted. I am now also obsessed getting the most out of my tanks. I never thought I could get this great of fuel economy on the Mustang. I think 600 mpt IS within reach, and my next two mods- rebuilding the underbody- and a lightweight aluminum driveshaft- should help me quite a bit. I think for the exterior of my vehicle, there is nothing more I can do.

I WOULD like to put hood vents in, like the 2013/2014 GTs- which would let engine air out- for the little getting in there.

I would also like side scoops just after the engine bay to pull air from the wheel wells, and/or engine bay.

But both are too expensive. The underbody is cheap, just hard work and logistics. The aluminum drive shaft is just having to spend 600 on it and install.

justme?



I made this past tank to 39.41 mpg. I was SO CLOSE TO 40! My main goal, not at this point, but next up, was 600 mpt. I noticed while driving back from a conference that I had 580+ mpt, and even if it meant walking, I was getting 600+.

My ultimate goal is to beat Fords record, 44 mpg on a closed circuit @ 44 mph, with the LRR tires and the auto tranny-while I will be on public roads, with GT rims/performance tires, and standard drive, just driving it.

This Friday my underbody is being installed- and I think my 40 mpg tank is coming soon!

38 mpg tank! Thats the fourth in a row exceeding 37 mpg. Tomorrow I am dropping off my coroplast panels, and Monday evening I am beginning the install of my underbody.

[UltArc]

41.84 miles per gallon. I was going for a 1k km tank, and in hitting that goal, I beat my goal of 40 mpg.

I am astonished I was able to achieve it. Careful driving, of course, but I definitely was not flawless.

Incredible

Incredible mileage. One thing though, to my knowledge Roush didn't introduce the RS until 2013. Roush adds V6-powered 2013 RS Mustang to lineup - Autoblog

Holy. Cow.

Did it require adding earplugs so you could keep out of the loud pedal?

Very true, sir! It is not titled as a Roush since I bought it first with A Plan through a dealer our family works with and at the time, they didn't have a production RS. The current RS has significantly less work done to it than mine, as they no longer do body modifications. For the 2012 and earlier, I believe as early as 2010, they made a separate front fascia which allegedly is very low in Cd. Combined with their air splitter, and lower partial grille block (it's more of a styling thing, but to me it is a partial lower grille block), Roush CAI, side splitters, and Roush exhaust, and Mustang GT rims/tires.

The 2013+ RS comes with Mustang GT rims, Roush branded pedal covers, Roush branded center console button, Roush branded floor mats, Roush branded plaque, Roush branded windshield banner, Roush branded gas cap, Roush branded grille, front splitter, lowering springs and more badges.

My work on my vehicle also did not cost +4k to start out with, or by the end.

It's essentially everything functional Roush made for the Mustang on my six, while the 2013+ is everything NON functional put onto a six, for much more. They gave me some badge stickers things, but they are a bit pointless, if you ask me. However now that I think about it, they never sent me the plackard or work order they said they would. Other than my amex bill and some work tags they put in, I don't have any record of it!

And ear plugs would help. It's extremely difficult to not abuse it, but I still have some loud fun, I really get my kick from carving corners and just the whole challenge of it.

Are you not driving the CTS V anymore? Or just not updating the fuel log? I especially like to follow other performance oriented cars regarding fuel economy when driven efficiently.

In regards to this tank, some loud pedal has dropped my fuel economy quite a bit. And, traveling maybe 1 mile through the very rear of Cedar Point last night took almost two hours. EOC/ engine cutoff helped me maintain 8.9 mpg for the whole way through it. I tested just idling instead of pulse and gliding, and my SCii MPG AVG readout dropped from 9.0 to low 8s, so I resumed P&G. I can only imagine what all the dodge caravans and big SUVs were getting-I know the caravans have smaller engines, but there were so many, and the big SUVs have bigger engines, usually less efficient in general, and no signs of a grille block. My tank average dropped from 35.7 to 34.7, by car readout.
