Will this work on a 2013 Boss 302? Will this work on a 201 Boss 302 and if so what kind of power will it put down to the wheels?

wthal7574 Year: 2013 Model: Boss

  • The Boss definitely has an advantage over GT''s due to having forged cranks, rods, coated bearings, and better valve springs from the get go but it would be nice if they had decided to put a forged set of pistons with all that too. This kit will easily get you 1000+ WHP I suggest a professional shop install and dyno tune the car. This kit won't disappoint, wish I had the Boss model but one GT is better than a LS if I may say so...

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!

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

Stangkid Year: 2011 Model: 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.

    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.
