Blow-By Racing and Hellion Power Systems multiply the SVT Raptorâ€™s fun by two turbos

Ford Special Vehicle Team main man Jamal Hameedi called on his background with the companyâ€™s Rough Rider off-road racing trucks to create one of the biggest performance vehicle success stories in recent Blue Oval memory. The SVT Raptor is equally at home cruising across desert terrain at triple-digit speeds as it is cruising the streets. Those attributes have contributed to its success.
As cool as the Raptor isâ€”and itâ€™s cool enough to make those indifferent to trucks want oneâ€”the typical customer for a performance pickup, like Fordâ€™s prehistoric performer, isnâ€™t one to just leave well enough alone. Of course if you want more than a standard vehicle, odds are you want even more once the newness wears off.
Such was the case with our friends at Hellion Power Systems in Albuquerque, New Mexico. â€œHellion co-owner Dwayne James purchased one of the first 6.2 Raptors when they came out, and we immediately felt it needed more power,â€ Hellion co-owner and NMRA Outlaw superstar John Urist explained. â€œThatâ€™s when the project started.â€
If you arenâ€™t familiar with Hellion, the company is born out of Johnâ€™s racing success with various power adders. This led he and Dwayne to create a company dedicated to building bolt-on turbo systems for various American machines. Obviously in our world, the Hellion turbos have propelled numerous super-powered Mustangs, Boss 302s, and Shelby GT500s.
While the Raptor is obviously a performance vehicle, it is also meant to prowl in much harsher environments than even the racing environments some of these Mustangs compete in. As such, the Hellion crew took the truckâ€™s mission into consideration when creating its turbo system for the SVT truck. â€œWe built the system with off-road in mind,â€ John said. â€œEverythingâ€”from the turbo brackets to the piping â€”is designed to ensure sturdiness and durability.â€
Built like all of the Hellion systems, the 2011-2014 SVT Raptor Twin-Turbo System features an all-stainless-steel construction using precision CNC equipment to ensure an easy fitment. As it turns out, all the work was with it, as the big Raptor engine really responds well to two turbos. â€œThe 6.2 engine, with its increased size, allows us to make more low-end power, which works out great in a heavier vehicle such as the F-150,â€ John added.

Now, as luck would have it, our friends at Blow-By Racing recently installed the system on a customer truck and offered to share their results with us.
â€œThe Raptor install is very straight-forward and the instructions were step-by-step. It is a time consuming process, and there are lots of part to remove and install, but it is well worth it when all is completed,â€ Blow-By Racingâ€™s Chris Jones explained. â€œWe estimate a 20-hour install time.â€
By looking at the results, weâ€™d definitely say the Hellion system is worth the effort, and Hellionâ€™s main man agrees. â€œBBR showed exactly what we saw on our R&D vehicles, over 650 engine horsepower with only 7 psi,â€ John explained. â€œThat is also done with a Third-gear pull, which will show lower numbers than a Fourth-gear pull. BBR likes to pull the trucks in Third so the speed is kept lower considering the size of the tires.â€
More importantly, the BBR customer loves his twin-turbo truck. â€œHe was very excited and still is,â€ Chris enthused. â€œAnd, even now after two weeks, I still get messages about how much he loves the truck.â€
â€œWe have worked hand-in-hand with Hellion and Chris from Dyno Edgeâ€”a dyno shopÂ local to Hellionâ€”to get this tune perfect. The truck drives and shifts perfect,â€ Chris added. â€œCurrently we have been using 47 lb/hr injector and testing has started with larger injectors now. Hopefully all tests will be completed in a few weeks. This truck is 100-percent stockâ€”right down to the cats, resonator, and full exhaust. We need to see how far we can go. Right now the dyno graphs show that at 10-11 psi we are out of fuel. At 11 psi we made 630 horsepower and 601 lb-ft of torque (at the wheels).â€

How do I not have one of these in my garage right now?
I’m pretty sure that’s my fault…
11 psi on the stock internals?
have fun while it lasts I guess.
WILL THE 2015 SVT RAPTOR BE COMING OUT WITH THE NEW F150 BODY STYLE
It wasn’t left at that boost level. Turned it back down to 7psi.
I bet it is still a lot of fun at 7 psi!
