Switch between pump and race fuel at the push of a button. Sort of.

We’ve made it – three months of weekly tidbits designed to whet everyone’s appetite for what Dodge believes will be the most amazing factory drag racer of all time. The last thing you need to know about the soon-to-be-revealed Challenger SRT Demon is that it can run on 100-octane race fuel. In fact, the manufacturer says it’s the first ever factory-production car designed to handle both race fuel and pump gas on-demand. But there’s a catch, and if we’re honest, it’s a fairly big one. Remember the Demon Crate we talked about a few weeks ago, chock full of tools and parts that will come with every car?

SRT Demon owners wanting to run 100-octane race fuel will need to delve into that crate for a new powertrain control module (PCM) and install it, along with a new switch bank for the center stack that features a neat gas button. Once hooked up, pressing the button will allow the car to operate on pump gas (91 octane minimum) or race gas. Mixing the fuels isn't a problem, as the Demon's PCM will monitor sensors and make adjustments as needed, including reverting to the standard pump gas programming if necessary.

We assume Dodge made this functionality separate to keep the Demon a street-legal vehicle sold through dealerships. We also assume that various engine and emission components are manufactured to handle the demands of higher octane fuels, but there’s no mention of specifics on this. Either way, the Demon leaves the factory with a PCM tuned specifically for 91-octane pump gas, which in our book takes a bit of wind out of the whole first-ever thing, since technically it’s not a function available from the factory. We’re splitting hairs here for sure, but then again, so is Dodge. Naturally there isn’t a mention of potential power gains from running race fuel. Dodge simply says owners will see “big changes” at the drag strip when running the high-octane fuel. 

By this time next week all our questions should finally be answered. By all questions, we mean just how much horsepower this car actually makes. 757 has been teased, but with all the pomp and circumstance – and especially with Hennessey’s new 1,000-horsepower Exorcist Camaro clearly aimed at the Demon’s horns – such a number would be terrifically anti-climactic.

Did we just say 757 horsepower in a muscle car would be anti-climactic? Well, these are good times we live in, aren't they?

April 6, 2017 , Auburn Hills, Mich. - Every part of the 2018 Dodge Challenger SRT Demon – from the supercharged HEMI® V-8 to the Air Grabber hood to the single-seat interior to the sticky Nitto street-legal drag race tires – is optimized for one mission: dominate street and strip.

That single-minded focus even extends to the fuel system, as shown in the newest teaser video, “Fuel,” unlocked April 6 at www.ifyouknowyouknow.com.

The Challenger SRT Demon is the first ever, factory production car designed to run on either track-preferred 100+ high-octane unleaded fuel or 91-octane unleaded fuel on demand. The track preferred high-octane fuel is readily available at select gas stations, specialty shops and drag strips.

The keys to unleashing the SRT Demon’s full fury are in the Demon Crate shipped separate: Direct Connection Performance parts that include a new powertrain control module (PCM) calibrated for the high-octane fuel and a new switch bank for the center stack that includes a high octane button.

The SRT Demon leaves the factory with a PCM configured for premium unleaded pump gasoline, which delivers top level performance.

The switch to the Direct Connection controller enables the supercharged HEMI engine to extract the maximum power from the knock-resistant high-octane fuel by optimizing spark timing. Drag racers will see big changes in elapsed time (ET) with the high-octane fuel.

Mixing high-octane unleaded and premium unleaded fuels in the tank won’t hurt the SRT Demon’s engine, but the high-octane function won’t activate if the combined fuel octane is too low. A message in the gauge display tells the driver the car will use the premium fuel calibration until the engine is shut off and restarted. How does the car know? The controller monitors the engine’s knock sensors.

There will be plenty of fuel available: The SRT Demon carries dual fuel pumps (vs. one pump in the Challenger SRT Hellcat), and larger fuel injectors using higher rail pressure.

Fans should visit www.ifyouknowyouknow.com to watch “Fuel” and "Judgement Day" as well as the other 2018 Dodge Challenger SRT Demon videos. Remember, nothing is a coincidence and everything means something.
