Supercharging an AT car will only result in the AT blowing up.

Don't listen to most of these people. There are a few supercharger kits out there for your car. Two of the most popular choices are the Roots based Jackon Racing supercharger and the centrifugal Vortech kit. Both will work fine on the car and you should not experience any issues with your automatic tranny. You will obviously have a lower power output than the same vehicle with a manual tranny, but believe me, you will not be disappointed. You will still hear the sound of the supercharger while driving. Personal opinion, I would go with a turbo kit such as one from DRAG. These will make more power than any supercharger kit and also require less maintenance. Contrary to popular belief automatic transmissions are usually better for forced induction applications, at least in a straight line, due to the fact that you can load the car up against the torque converter by braking and gassing at the same time which will produce boost from a standing start unlike a manual transmission car. A few things to remember, with any forced induction application you will want to take the car to a reputable tuner and have the vehicle at least street tuned using a wideband O2 sensor. Many kits come with fuel pressure regulators and such to allow the vehicle to be run without a tune, however you will not realize nearly as much power with those as you would with a tune. My suggestion for any Honda is Hondata ECU's. I have used the s200 and s300 on many project Honda's and they are amazing. They provide nearly as much customization as the AEM EMS without be nearly as pricey. The s300 will start around $500 and the tune will cost you in the neighborhood of $50 to $75 an hour. Plan on 4 hours for baseline maps.

You can add a supercharger to an automatic transmission engine. If done right, you shouldn't hear anything different from under the hood. If you do, something's wrong.

If you've heard a car hiss as they're shifting gears, it's because they have a blow-off valve (BOV) to equalize the pressure between the intake manifold and a turbo setup. A turbocharger will keep pushing air in to the manifold even if the pressure in the exhaust is lower (called 'spooling'). Too much air and pressure in the manifold tries to trip the MAP sensor, and can cause cylinder detonation and break rods and crankshafts. The BOV tricks the MAP in to thinking there's a good balance of air and fuel, even though there's extra pressure.

A supercharger runs at regulated velocity depending on how fast the crank shaft turns with belts and pulleys. The faster the crank turns, the faster the pistons move, and the more capacity for air the supercharger can push.

A turbo is regulated with a turbine by the exhaust pressure leaving the engine and a BOV and bypass valve.

A supercharger will give you 'off the line' power while a turbocharger's benefit is down the strip. Instant power now on a supercharger, or spool up to power with a turbo.

When adding power to your engine, don't forget about the other things that can go wrong. Your engine was designed for only so much power. All Hondas have aluminum engine bodies that can take only so much heat and pressure without internal strengthening. Squeeze a sealed soda can. It has some give. Now, shake it up. It has so much pressure that it feels solid when you squeeze it. Now keep shaking it, it will eventually explode.

Consult a professional tuner before just adding a super or turbo charger.

you CAN, as in it is possible, but it is going to be a HUGE pain in the ass.

first off, honda engines and super chargers dont mix well because of heat issues. if you want FI, you'll get MUCH better results going turbo.

secondly if you want to safely run FI you need a tune, and auto trans take a lot more to tune than a manual. most shops wont even waste their time and your money on that headache.

there are 2 brands taht make/made reliable SCs for honda engines: comptech and jackson racing. neither of them make them anymore though so you'll have to find a used one most likely. and dont waste ur money on Hondata: ECTune and neptune are just as good, have the same features, and cost what they actualy should cost...half the price of hondata is the logo.

if you want my advice: convert to manual and go turbo.

1. Yes you can supercharge an automatic.

2. No, it won't sound any different, a supercharger and an engine don't care what the transmission is in it.

3. The only thing that's different will be the ECU, because it has to control the transmissions shift points.

Some of the other answers are correct in the specifics, and the hardest part about modifying the automatic is the ECU for the very reason I mentioned, because it controls the shifts as well as the engine.
