What can i do to get more horsepower and torque?

Question

I have a 2000 Mercury Grand Marquis GS with a h-pipe 2" dual exhaust, and two 2.25" flowmaster super 44 mufflers. I also have teh K&N cold air intake. About how much horsepower and torqe do i have now on ym current setup? And what can be done to get more horsepower and torque?

Answer 1

I have done many such things that you have tried on your car and using a G-tech Tesla and a cam-corder to log the HP curv, I have come up with far less real world HP gain than what was advertised. for a total of only 12HP and about 500 dollars down the tube.
My experience with engines of all kinds has come to one final all encompassing answer to your Question. There is the High dollar way and the relatively easy/ cheap way.
Port the heads, intake, exhaust, (just to keep things looking stock, bigger cam and a re-programmed ECU. Then maybee a compressor of some type blower or turbo (Lots a work or big bucks)
then there is the displacment game. BIGGER MOTOR

OR:
two steps colder spark plugs, a bigger fuel pump and a two stage NOS system with a 30-50/ and maybe a 75-100 HP split. Make sure that it is a wet system (injects fuel and NOS)
Remember that Horsepower and torque is always the same no matter how you get it and with less than 700$ and about 1 day worth of work its hard to beat. You dont use the extra thump all the time so the bottom end wont launch as soon as with a pump.
“ Has your blower been beat, by the guy up the street, with nitrous under his seat?”
(Unknown author 1985 ish)
A 45/75 split makes my 96 sable GS with 160,000 a lot more fun than the stock 145hp
MAKE SURE that you dont start dumping nos under 3000rpm and dont get to silly with how much you use. after the first time I used nitrous.......... it was the most fun engine mod I ever made!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 2

Bellieve it or not, the car is computer controlled and all that stuff was a waste of money. The car senses too much air and compensates by setting back the performance a little. you and 99 percent of the consumers of those gimmicks only think you have gained some power. You got not as much--the manufacturers got the money. You can try resetting the computer--disconnect the battery pos and neg for 15 minutes--restore it all and you may get a difference but this works even without all the after market stuff. I did this with my 99 Suburban--now it runs like new again--what a surprise I got. 19-20 mpg and pretty peppy for 145000 miles.

Answer 3

Adjust the fuel curve. "computer chip!" You probably gained 10 to 15 horsepower from stock with current set-up. See if there is Dyno testing in your area for more accurate horsepower rating.

Answer 4

You could add a chip or reprogram the one that you have. You will have to use hi-test gas from then on.

Answer 5

get a turbo or super charger,... or nitrous. both cost big $$$ and make it a lot faster.

Answer 6

ummmm go get better oil
