1200 horsepower, 35mpg Mustang

[JQmile]

I was fortunate enough to go on Drag Week and hang out with Mike Woods, and I can tell you this car is for real. He was on an 800hp tune when he ran the 9.91 pass, but there is a lot more left in the car. The crazy part is that he was running at 2200rpm down the freeway, and with that diesel is happiest (mpg-wise) at about 1600rpm. I think 40+mpg is possible, and when it's dialed in, it should run high 8s at 160mph in the quarter mile. Has to be some kind of hp per mpg record

LOL... and they say you have to choose between HP or efficiency, one or the other... electronics can do sooo much that standard wrench turning can't.. I love it.

At first it sounds fake, but I have seen a few trucks running 10s in the 1/4 and are still dailey drivers with turbo diesel 6's.

My 12 second Neon has gotten a best of 32+ while a V8 GTO buddy and a few 12 second Vette get high 20s....not to mention a fully loaded SRT8 Chrysler 300 that is also a dailey driver getting 10s in the 1/4 and 27 mpg with his nearly 5000 lbs of wt.

WoW! That is sooo coool!

Heh! And this comes from a (ahem) Honda CiViC driver...

Mustang and CiViC owners are eternal, immutable enemies - for those that don't know!

Here's (an enhanced) pic, before it disappears off that site:

If I'm not mistaken...

There aren't any intake manifold or exhaust headers on those things!

Is that correct?!?!?

There are a couple issues I have with this.
1. It is a mistake to only look at highway numbers. All the manufacturers are doing that now on the commercials but it is not a realistic, nor entirely honest.

2. There's no substance to that article. Who has independently verified any mpg claims? People making claims are a dime a dozen (see fancy spark plug threads).

3. Aside from getting everyones naughty bits excited, what's the point? Ok, maybe that one is rhetorical

Wow.. way to make my "naughty bits" go limper than a worm on a hook... lol.

Normally, that's all you have to go on, is what others say... and the EPA estimates that are quoted in commercials are almost always wrong anyway... even before I knew what EPA estimates were, I was beating them consistently.

I can agree with not believing outrageous claims without substantiating proof, but the odds of hundreds of people reporting claims like this without any seemly background as related to each other (no way to make the story up together) are not very high.

It's kinda like judicial court... if 400 "witnesses" say they saw you do it, and they're all from different parts of the country, with no personal interaction between them, you're guilty.

That's my opinion, honest as it is.

In defense of the OP and anyone else who might make these claims, I've personally seen cars running mid 10s to low 12's and still pulling down 30-39 mpg average... probably 64/36 mix, highway preference, due to the area I live in... it's mostly highway, open stretches of road, 45-55mph limits, no red lights/stop signs.

My own Civic has about 120HP (estimated), and I can drive it like an idiot all day long, and still get 34 MPG... for those not in the know, that means that the car has 30% more HP than it came with, and still better than EPA estimates, both old and new.

This article is very misleading.

He is NOT running 1200 hp and getting 35 mpg. On the highway the nitrous system is not running. The diesel computer is dialing back the wastegate on the turbo to an economy mode. When he goes racing, he UPs the boost big time and turns on the nitrous big time.

On the highway I would be surprised if he is producing 250 hp.

What the article doesn't say, says a lot more than what is says.

[Duffman]

I think the 35 MPG is a lot more believable than the 1200 hp. Dave is getting 27 out of his super duty and trucks are bricks with huge frontal areas.

For those of you who know nothing of modern performance diesels, the things that they do to make more power also make them more efficient as well, such as advancing the timing and increasing the injection pressures and diesel already run very lean under light loads. Because diesels effectively knock to run they are not octane limited, you can keep pouring the fuel in as long as you can supply enough o2 until they bust. There are more than a few 800 hp diesels on the street from the big 3 right now.

I was trailing Mike on drag week in a rental car, and I can tell you he's averaged 33mpg twice over different states and this was including his dragstrip passes. His nitrous system was setup for about 200 extra hp, so the Mustang was about 600hp on a street tune with no nitrous. Still faster than any of my piles. Here's a video of him crusin'....I have the rental car floored trying to catch him...LOL

Cobra, I thought I mentioned earlier that the ECU was controlling the engine to make it have 1200 HP or 35 MPG... maybe that wasn't clear.

Obviously you're not going to run 1200 HP on the street and still get 35mpg... but you (generalized, not YOU specifically) fail to equate that the 1200 HP is also at full throttle, and the highest power building point in the engine's rev range, which wouldn't be touched (normally) on the street.

For instance, if the engine built 1200 HP at 3200 RPM (not at all uncommon for a truck diesel, to have a power range so low, and extremely long gears), chances are, on the street, he's minus the funny gas, slightly detuned, and never actually hitting his max power range (probably driving around at not much more than half throttle, shifting under 2800).

It IS quite possible, especially on a ECU-tuned setup, to have both high HP and high MPG figures. Since most anyone that tunes ECU's can set them up to have multi-map features, which can be changed at the flip of a switch.

His car is OBD-2 diesel, so the banks six-shooter (name?) or the BullyDog diesel tuner could more than well do it for him, as a piggy back system.
