how do i increase horsepower on my twin turbo mitsubishi?

boost controler , hard pipe kit , greddy blow off vale, bigger inter cooler but not to big you will have boost drop with a bigger inter cooler , kn air filter , 3 inch exhuast all the way back , change from a twin turbo to on big turbo like a super 25g is my fav , standalone ems , after all this you will need a new clutch to like a stage3 act is great ,

At Mustang Racing Technologies we run a Novi 1200 supercharger on our 2005 at 8.5 psi.  We have no problems and have had it higher.  With current boost it is putting out around 400 horses.  If you are planning on more than 5 psi you need some serious computer remapping and fuel help.  CPR fuel rails, injectors, and an SCT tune are suggested.  Don't worry about the intake.

Get a Mustang GT and a Paxton supercharger kit. You should be running 450-500 horsepower at the rear wheels with that setup.

Contact the Early Ford V8 Club.  They're the experts on flat-head V8 engines.

You can't go wrong with a high flow exhaust and a high flow air filter, it helps the engine breathe a lot better and should also increase economy.  It might be a bit louder though...

Eliminating backpressure in an exhaust system always creates more horsepower and more torque. Headers are excellent. The more efficient the exhaust system, the greater the power gains. \n\nThere are lots and lots of good brands of mufflers, catalytic convertors, and headers out there. In terms of mufflers, some of the best ones are: Flowmaster, Borla, Corsa, Hooker, etc. \n\nThere are lots of ways to increase performance, mate. Use high quality spark plugs, and spark plug wires. MSD ignition creates a more powerful spark, as well. Synthetic oils for the engine can also add power. Get a nice tune up using high quality parts. \n\nGood luck.

I would just run it at 60 Hz. Output rpm will be 20% higher. \n\nAlternately, you could get a 400V VFD and set it's output to 50 Hz.

To start, I'm not a "tuner guy". It seem one would want to istall a performance exhaust to allow more air flow and a computer reprogrammer to override the fuel efficient factory settings. These things alone will gain you maybe 40% more horsepower. Tuning the suspension is a big next step to get the most from your newfound power. \nThere are tuner shops who could give you lots of tips on performance or try this site. http://importtuner.com\n\nGood Luck !

Short answer: Install a large turbo.\n\nIt depends on what type of engine you have.  If you're running a KA18DE, good luck.  You'll have to tune that engine about as heavily as possible to take it up to that much power.  However, if you have an SR20 engine, you're in a much better situation, as those can withstand much more power.  \n\nIf you have a KA18DE engine, I would suggest saving your money for a SR20DET engine, and having the SR20DET rebuilt.   That will cost more than your current budget, but will be worth it. Then, install a large turbo on the SR20DET.  I would guess that all that work may cost as much as $8k-10k, depending on how the SR20 market is right now.  \nYour other option with the KA is to install a turbo, and hope for the best. I don't know if you'll be able to pull 300HP though, especially with a tired old engine.\n\nNOTE: If your engine is naturally aspirated and hasn't been recently rebuilt, I wouldn't reccomend installing a turbo, as you're likely to blow it.\n\n**for reference** "S13" refers to an older model  (86-92?) Nissan 240SX\n\nDisclaimer: I drive a Mazda RX7 (FC3s), and have not personally  done any work of this nature on an S13.\n\nFeel free to send me a private message (I think you can on these boards) and update me/ask for more info  on the situation.

a turbo will blow ur motor, get a cold air intake its pretty cheap and it will give u about 10-20 more horse

For a car?\nif you mean accelerate, go with gasoline\nSupercharged, turbocharged are nice for getting more power

If want you really want is more power out of your car, a bigger top speed and some extra revolutions per minute. I would recommend to buy a sports chips. There is no mechanical way to by pass the rev limiter and if you could get out more revs out of the car, without modify the amount of gasoline getting in the engine you would not get any kind of benefit.

It depends on your "theoretical hull speed" (see the link below). For your boat, that would be around 5 knots. The motor will speed the boat up to that point, and then adding more power will not do much. Then, there is another threshold where the boat pops out of the water and onto a plane, but that requires a motor so big it wouldn't make any sense for your little boat. That means to save money and gas, you should just use a motor that is just big enough to drive your boat up to hull speed and not much more.\n\nAs a general rule of thumb, you should have 1 hp for each 300 or so pounds of displacement to drive the boat at hull speed. Remember that your 500 pound boat will have, let's say, 3 150-pound people on it, so that will bring the displacement up to 950 to 1000 pounds or so. That means you should have just over 3 hp to drive your boat at hull speed, so I'd go with the 3.5 if I were you. \n\nSorry, don't know when the Merc/Nissan/Tohatsu four stroke 3.5 will come out.

Headers decrease back-pressure which increases horsepower.  Dual exhause allows for free flowing exhause - to increase horsepower.  One thing with more modern cars, you would need to add a second o2 sensor (some v6 or v8 cars have a single o2 sensor at the end of the crossover pipe).  Dual tail pipes is way more common than genuine dual exhause - you do need two of everything (o2 sensors, cats, ect).

Here in my view are the pros and cons of each:\n\nAdding a custom turbo to the GS: pros: you can select the turbo, it doesn't have to be the stock GSX turbo, but you have a lot of good choices, for example the Mitsubishi TD05-16G or TD05-18G.  Cons: you will need bigger injectors, fuel pump, and engine management. I highly recommend custom dynotuning for safety and performance. Torque-steer: with FWD and additional torque, you will encounter significant torque steer. This shouldn't be a problem if you are aware of it, and drive carefully. You will probably need a new clutch to handle the additional power.\n\nGSX: pros: less torque steer due to AWD. Injectors and pump are already sufficient.  cons: AWD drivetrain will have more driveline loss of horsepower in exchange for better handling.

you won't notice a difference with 5 hp gain, you want top end or bottom end speed, i suggest changing rear end gears for big torque gains, can make a little 4.6 boil those tires but not mess with factory engine components that are set for optimal engine life. e-mail me for  furhter help, jsconyers6401@charter.net

If you know how many watts the motor can provide then dividing that by 746 will give you horsepower.\n\nThe Amperes and knowing the supply (ie. 220V) can give you horsepower since amps times volts gives watts.\n\nThings get complicated if these readings are not a measure taken just before the point of stalling the motor with a load on the motor to induce it's full power output.
