Here are some ideas on how to increase the HP in you Honda. I though this nfo was helpful and maybe will work in my accord...... Any iput ????



There are many things you can do to increase the power of your engine. I'll briefly list and explain just a few ways.


1) Decrease air intake temperature
--Decreasing the air intake temp causes more oxygen molecules to fit into your combustion chamber, which then requires more fuel for combustion. This causes the combustion reaction to explode with more pressure, and more power. Hot air intake would not allow as many oxygen molecules to enter combustion, hence making a weaker air/fuel combustion reaction.

2) Increase the intake flow
--It is very important to let the combustion chambers of your cylinders recieve as much air as possible. With a restricted air flow into the cylinders, it creates more resistance when the crank has to pull the cylinders down for air and fuel.

3) Cram more air into combustion
--This is why turbos are used. Cramming more air molecules into the combustion chambers requires more fuel to be let in as well. example- A combustion chamber packed with 1 trillion air molecules and 1 million fuel molecules, would be much more flammable then a combustion chamber that contains 1 million air molecules and 100,000 fuel molecules. A more flammable combustion reaction will push the cylinder down harder, and faster.

4) Let exhaust exit freely
--There are a few ways this can be accomplished. One of these internal modifications to let exaust gases exit more freely, is to purchase cams that allow a higher exaust lift for the valves. Another way to increase exaust flow is to purchase a free-breathing exaust system. Normally people only buy an aftermarket muffler without the necessary wide piping. This helps the exaust gases exit very little compared to purchasing or custom fabricating an entire exaust system. However, be aware that an exaust system that breathes too freely will cause your car to lose all back pressure, and can actually decrease performance. Turbos on the other hand, need an easier breathing exaust system due to the increase of air flow.

Also besure to retune your engines ecu after any mod to your car, without it you basically are going to run to rich or to lean, which in turn doesn't give you the most out of your mod, let alone ruin your engine. Thats rule number two, number one is know what you are doing.

I will have to agree with SJ, without a tune your installs are pointless

glad you put source info cuz all that info was about stupid.

an engine runs off a controlled burn not a explosion,

resistance in the intake ok, but a cylindar is not filled by the piston pulling air into it but by atmospheric pressure equalizing.

and the fuel, thay could atlest use real numbers WTF you want like a 13.5/1 for NA and 12.5/1 or lower for boosted at WOT

for the exhaust you dont need bigger exhauts cam for a stock engine cuz the exhaust is being pushed out a good Header and Cat back will be fine.

if your running NA the factory ECU will be fine for the normal bolt-ons, if you have a factory turbo car thay will normally be ok with bolt-ons but i would install a Wide Band O2 sensor not one of thoes gay ones that go off your factoy O2 thay are about good for nothing, make shure the A/F is good the factory ecu wont allow it to run more timing so its fine till you star to turn up the boost.

and guys not put a turbo on your NA car and drive it around not tuned, get a wide band and have a local tuner tune it or it WILL blow up.

any more questions just post and i will try and get back to yall

Thanks k20, if you wouldn't mind post somemore info about hondas, being that you are from there you might have some informative shit. Thanks again
