Will a larger intake on my car add horse power and improve my fuel economy?

That 'Hard Luck' knows NOTHIN about cars!  By adding more air to your engine, your air-fuel mixture improves resulting in less fuel required to get the same if not better effect.  So, you get better fuel economy and possibly up to 10 extra ponies squeezed under the hood.  I have witnessed this first hand with our Honda fourwheeler after installing a K&N air filter and a custom Glass pack exaust. It sounds fricken AWESOME!

Most gains are overestimated by people.  You have to remeber if making the intake slightly bigger was going to give you a lot of power, most manufactures this day could easily make their intake tube bigger for slightly more per car, if itmade a noticable differnce, tehy would.\n\nEven these days factory exhaust are much bett erthen they used to be.  There was a time when you could easily put an aftermarket exhaust on and gain 10-20hpo, but today, the gains are small, and often only their when the engine has been heavily modified\n\nWorse yet, those power numbers they tell you, are often only at one spot in the rpm curve, so it will not be a continuous gain of power, sometimes they will even loose power on the low end to report a power gain at the top end, which depending on what you do cna be good or bad.  But generally on teh street, low end power is wher it is at, thats what pushes you into your seat when you punch it at a light.\n\n(this is part of the reason you can oversize your exhaust and loose power, removing cats will often loose enough back pressure to acctualy hurt the low end power, my dad gutted the cats on his 88 mustang GT, lost all it's low end power, it didn't take him long to find a nother set of stock cats to swap back in)\n\nCheck out some forums for your car, find what real people have done to their car, and what really works, you may be suprised at what cheap things work, and how many things really don't

Well you can do something like a nitrous kit thats quick and easy, very cost effective. You can unlock that much with bolt ons too. Headers, full exhaust, cold air intake, plugs, wires, msd ignition box along with their new cap and rotor. Then get it tuned which is very under rated, you can unlock a lot of power through proper tuning. I dont mean hypercrap or supertrash chips but send you ecu to someone and get it tuned to your individual application and it even costs less to do it that way.

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.

Turbo charging does affect gas mileage. Typically not as much as supercharging which draws power directly from the engine. However, both will reduce fuel economy slightly since you never get something for nothing in life. The gain with a super or turbo charger is of course is more power because as the prior post points out you're adding more air so you can mix more fuel to get more power.

Horse power can be used for both it is a value given to the amount of energy needed to perform (x) amount of work per second.\n  I believe you are more interested in thrust, which is the forward propulsion of the jet engine.  \n  That would go more towards ft/lbs.  \n\nOne extra little known tid bit.  The super jet engines like on the C-5 military transport uses some water injection on take off.  This is what causes the dark exhaust you see. \n\nIf I remember correctly when water flashes to steam it has a 1:26 pressure expasion rate.  \nAs you can see this has a significant impact on the amount of thrust for the engine as well as a cooling effect.\n\nAnd of course the lift is all by design of the wing.  If you took the wings off of a plane it would never get off the ground...  \n\n    But it would make one fast car !!!

With the right Modifications, like taking the body off and putting it on a real frame, you could put a 454 chevy in it. And really, that is no less practical than anything faster than the stock V6. I have a 99 with a 4 banger, and it will pull the car faster than it can be safely driven. You are looking at serious suspension mods. It aint no Honda.

Are you talking cubic inches or horse power or both\n\nIE you can get 408 hp from a 400ci with the right cam heads intake and carb.\n\nYou can also bore out an engine block to increase the cubic inches, IE bigger pistons and rings.\n\nAnd as the previous poster wrote you can make it a stroker motor

Nitrous Oxide injection will add MAJOR horsepower to your engine for a relatively small price, but it could also blow up your engine if you're not careful with it...

these increase fuel consumption for 2 reasons .using a/c increases fuel consumption due to power being used to power the a/c's compressor. this is a pump to circulate refrigerant gas around the system. open windows increase fuel consumption due to increased wind ressitance /drag of the car when windows are open.

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

It seems highly unlikely that your Honda has that kind of off the line accelleration, I know my 88 Civic, great as she is on the highway, takes 14 seconds to go from 0 to 60 on a good day and mine has no catalytic converter.

"turbo" used in normal piston driven engines uses the exhaust gasses energy to drive a (typically) radial turbine that is connected to a compressor that compresses the intake air. \n\nThe increased amount of air (mainly the oxigen in interesting) allows to add more fule to the mix and create a larger explosion in the cilinder yielding more power.\n\nThe air can optionally be cooled using an "intercooler" (air-to-air heat exchanger)\n\nFor diesel powered engines the result is an increase in power of the engine and an improvement of the fuel economy. For gasoline powered engines the results are an increased power, but the fuel economy might go either way.

The big engine weighs more and uses more fuel.  If you are regularly carrying giant loads up steep hills, or pushing a really enormous vehicle, the 400 is the way to go.  But for everyday driving, you really don't need a whole lot of power.  A simple 2-liter four will get you there just as fast for just over half the fuel.\n\nThere are grey areas.  A big, torquey engine geared way down can actually deliver pretty good efficiency. A small engine that's overworked can be inefficient.  A 400 (over 7 liters!) vs a 2-liter is a no-brainer, the 2-liter will use less fuel every single time.  But there are cases, particularly on American vehicles, where the v6 will deliver both more power and better economy than the 4.\n\nRule of thumb: so long as you can scoot around happily without pushing too hard on the gas pedal, your engine is big enough.  Most engines are bigger than they need to be.

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.

Yes but first your engine should be in good running order. If your engine is clogged or just runs like S#@T then it won't help much.

Better flow of the exhaust (which increases performance) vs the stock exhaust.
