    Can you install this if you have the BOSS 302 intake manifold on a 2011 GT?

    • Yes this kit was also designed to fit the Boss as well as the GT, so if you have the Boss manifold it will fit.

    So I have a 2012 get premium with a roush intake and exhaust system. Is there anything I will need to add to the engine before I would install this kit? And does it come with both intakes? I'm not that great at knowing what is what

    • The Hellion Twin Turbo is a complete kit and will come with everything necessary for installation. Since the kit will need a custom tune, it would be difficult to say what additional supporting modifications would be needed with out know how much power you are planning to make. Depending on the amount of power you are expecting to yield, we would recommend a high flow oil pump, and external oil cooler, upgraded radiator and fans, along with a heavy duty clutch. Additionally, this complete kit comes with both filter for the turbochargers. Ford Performance High Performance Gerator Oil Pump, item 50354 Mishimoto Direct Fit Oil Cooler -black/silver, item 102125 & item 102124 Mishimoto Performance Aluminum Radiator - Manual, item 80203 C&R Racing High Capacity Performance Radiator, item 102405

    Will this setup work on the cobra jet manifold?

    • The Hellion Turbo Systems are built to order for our customers, which Hellion will tune for the applicable manifold. Typically for Boosted applications we will suggest the Boss intake manifold and suggest the Cobra Jet for Naturally Aspirated applications.

    Stock internals? Whats the max PSI on stock internals? Whats the max HP you can make with stock engine/internals?

    • You can make over 1000+ WHP on a stock motor with 20+ PSI of Boost, BAP and a Race fuel. But the question is how long will it last, not long at all. Most "reputable" shops and tuners (JPC,Lethal,etc.) will try to keep you at around 650 HP for longevity on daily driven pump gas cars. This is for a GT model. The Boss Mustangs come with forged crankshafts, forged rods, better bearings and valve springs so you can turn those up significantly higher, but to each his own. Plus stock auto trans cars can handle way more compared to the manual versions which should be upgraded to a Tremec Magnum XL or other stronger version.

    Would i have to make any changes to the transmission, spark plugs, etc? I have a 2014 GT and someone just bought a viper srt in my town. I want to completely destroy his car in a race.. So far I have not lost a race! But have i meet my match?

    • You could surely make him regret spending so much money for a Mopar with this kit or other mods. If you have a automatic trans then a tune and new converter plus a Aluminum driveshaft, with some wider wheels and tires should do the trick. But do your homework, I never like to see any Stang banger gettin beat up on. Those cars come with a Tremec T56 manual which is what I would recommend for you if you get this kit and have a manual equipped car, but the newer Magnum XL version is more revised and is rated at 700+ ft. lbs. Of course it's not the car that wins the race. It's the car and educated driver who win races. Please for all of us Mustang and Coyote owner's, send the Viper, Snake Bitten, chewed up and spit out King Cobra style!

      Awesome power

      After months of begging to my wife about purchasing this product she finally said "ok get it". Right away I got my iPad and purchase it. I've became the happiest person once I got my car back.
