At ******, we’ve always tried to push our more aggressive customers into switching to race fuel when they start to get “out of hand” with higher levels of boost, especially when mixed with the higher compression of today’s 4-valve and 3-valve 4.6L’s ( 9.8 to 10.1:1 ). Convincing people to run pure race fuel has always been an uphill battle for me, because race fuel is two to three times more costly then regular pump gas, and its very inconvenient for some people to find locally. It’s important to understand that when trying to make big power “SAFELY” out of only 281 cubes on the street and the track, in heavy cars - you have no choice but to sneak up on more boost - boost levels that are often not safe with just 93 octane. This leads to the requirement of more octane no matter how you look at it, even if they’re intercooled with big boost. And we’ve already established that reducing the compression on street 4.6L’s is a very bad move overall, plus this leads to expensive and unnecessary engine rebuilds if the stock engine is in good shape and ultimately tuned correctly with boost.

We are clearly seeing that Alcohol injection on a Vortech equipped Mustang is not only safer then true hardware intercooling, but has the potential to make even more power overall than an intercooler upgrade on the centrifugals. We can’t stress enough that with a Alcohol kit you basically get 2 big upgrades out of the deal. First a big drop in inlet temp that’s not affected by intercooler hardware heat saturation, and second a big jump in octane. A third advantage comes from Alcohol kits: it can take over where your old fuel system falls off and allow more boost and RWHP without having to go to bigger fuel injectors or other fuel system upgrades in many cases.

Now for the specifics. ***** has established a 12.5 psi Vortech package for the ‘05 and up Mustangs that will net 470+ RWHP with absolutely nothing else done to the car. This package is simple, clean and works! Its all happening with the stock fuel pump in the tank and no Boost-A-Pump either, only 39lbs injectors which come in the Vortech kit. The package consists of a 12.5 psi Vortech S-trim and an Alcohol kit as well. This is all happening with 91-93 Octane in the tank. And realistically could probably be done with 87 octane if we tried. This is all done with an ****** custom tune using SCT software to take full advantage of the use of Alcohol.
