While the 2015 Mustang horsepower arms race is heating up, there is still a superpower. The company that has put down the biggest horsepower with an S550 so far is Hellion Power Systems, which rocked the rollers to the tune of 949 horsepower at the rear wheels. It did so with the companyâ€™s Eliminator twin-turbo kit, which debuted at last yearâ€™s SEMA Show.
Thus far, tuning the power-adder Mustangs has proven challenging for many, but Hellion was able to lay down some serious numbers running the stock TriCor PCM with a Blow-By Racing tune.
â€œThe nature of our system and the headstart in tuning and R&D that we have had has paid off,â€ John said. â€œIt runs perfectly.â€
With those performance credentials on record, you might think the Hellion team would be willing to rest on its laurels, but thatâ€™s far from the case. Main man John Urist isnâ€™t one of the most decorated racers in the National Mustang Racers Association ranks because heâ€™s easily satisfied. He does, however, want to satisfy Hellionâ€™s customers.
â€œWe receiving numerous requests for something that hits hard down low,â€ John said. â€œWe talked to Precision Turbo about building us the smallest state-of-the-art turbos in order to still be able to make big power and deliver instant low-end response. Precision built these 55mm units specifically for us.â€
â€œTurbos have sometimes had a stigma of not having low-end power and people thought you needed a positive-displacement blower for that,â€ he added. â€œOur 55mm turbo option eliminates that stigma.â€
The Hellion Eliminator twin-turbo kit that put down the big number was equipped with two 62mm Precision Turbos. To see how the new 55mm units compared, John swapped out the turbos on the companyâ€™s in-house test car and headed over to The Dyno Edge in Albuquerque, New Mexico, to run it on the Dynojet chassis dyno. Both configurations were dialed in for about 12 pounds of peak boost, but the smaller turbos clearly made a difference down low.
â€œIt hits harder. Heavily modified Coyotes with the most advanced positive-displacement technology canâ€™t come close to the torque and horsepower that our system creates,â€ John said. â€œLook at the curve. Itâ€™s making almost 500 horsepower at 4,000 rpm, and itâ€™s making over 640 lb-ft of torque at 4,000 rpm.â€
As you might imagine, this increase in midrange performance is something you definitely feel on the street.
â€œItâ€™s amazing,â€ John enthused. â€œIt has instant throttle response in all gears at virtually any rpm, but it drives exactly the same as it did with the larger turbos on the 12 pound setting.â€
If you are ordering a Hellion kit, you can opt for either the 55mm or 62mm turbos for the same cost. This makes it easy to select the sort of power curve you desire. While itâ€™s tough to beat the smaller turbos down low, if you want even more power, there are larger turbo options as well.
â€œThe 64s are capable of 1,400 horsepower. The 55s are still capable of almost 1,000,â€ John said. â€œFor anybody looking for maximum performance we can always option to the 64s.â€
If you need a refresher, you can see the Eliminator system run on the dyno with the 62mm turbos right here:
