I HAVE A 2000 MERCURY GRAND MARQUIS. I HAVE A 4.6 LITER ENGINE. I LOOKING TO GET More HORSEPOWER Out Of It.?

Q: LIKE 50 OR MORE HORSES. WHAT OPTIONS DO I HAVE?PLEASE GIVE ME YOUR BEST ANSWERS. THANKS

A: there's lots of whys to do this, and its all in how much do you want to spend and how fast you want to go? headers, and a high flowing exhaust with an H-pipe can give you as much as 21hp and up to 30lbs of torq. roller rockers will give you as much as 8hp and 12lbs torq. after market pulley's can give you up to 15hp. K&N filter 3hp cold air in take system up to 8hp bigger throttle body and injectors with new fuel pump as much as 50hp and 60lbs of torq DFI injection we have seen as much as 100hp and the same in torq on the dyno. ignitions and spark boxs up to 30hp reprogramming you PCM for power as much as 45hp and 55lbs of torq, and by reprogramming your shift points will help your 0 to 60mile times alot all this can be done in your drive way. and all those gains are on the high side, most will see half of what i posted in hp & torq gains and everything you can get from summitracing.com or call them at 1-800-230-3030
