Just fit a viper (cheapest) can to the standard downpipes and raise the needle 1 position in the carb for an instant boost.

The pc downlonds for games is to slow , and the game i was playng air raid this is not a drill is warking ok but i need to know if i can get more fire power or longer life win i m shooting the deck gun ....

Hello !
I know that want have some fun using the deck gun too. so flow this instruction below :
Install info:

As with all my mods, this mod is jsgme ready and it includes a read me file. Open the downloaded zip file and then open the mod folder.

Inside the read me will tell you about the mod and the folder next to it is the actual mod itself. that is the folder you need to put into jsgme.

if the mod has more than one version then just choose the one you wish to use or the one that was made for your game version.

download link :

information About this Mod :
This mod will increase the damage caused only by your deck gun shells by increasing the shells effective strength (explosive impact) and i also increased all the shell speeds up about 20% from where they were originally set at so you should have a little less droop or downward angle to your shells.

shell reload times are now set at about 2 seconds for faster firing rate, the original stock setting was set at 4 seconds.

i also gave you a much larger ammo reserve so you wont be running out of ammo during your missions.

i have also increased all of the AA guns ammo reserves and reload times were cut in half for them but i left the fire power strength of them alone.

if any conflicts show up with other mods then just install this mod last and overwrite any files.

Good luck

I am looking to increase my lil 1996 xlt does rangers horse power it is a v6 4L auto and I was gonna put in a cold air intake was wondering if this us a good idea or any other sujestions on what to so I...

Cold air will help and free flowing exhaust. Headers and duals would give you the increased HP you are looking for. Make sure all sensors are reinstalled on any mods.

My pulsar 150CC silencer is partially rusted. It has a hole & so the noise level increased. If I dont change the silencer now, will the engine get affected ?

Some say that "an engine needs backpressure to work correctly." Is this true?
No. It would be more correct to say, "a perfectly stock engine that cannot adjust its fuel delivery needs backpressure to work correctly." This idea is a myth. As with all myths, however, there is a hint of fact with this one. Particularly, some people equate backpressure with torque, and others fear that too little backpressure will lead to valve burning.
The first reason why people say "backpressure is good" is because they believe that increased backpressure by itself will increase torque, particularly with a stock exhaust manifold. Granted, some stock manifolds act somewhat like performance headers at low RPM, but these manifolds will exhibit poor performance at higher RPM. This, however does not automatically lead to the conclusion that backpressure produces more torque. The increase in torque is not due to backpressure, but to the effects of changes in fuel/air mixture, which will be described in more detail below.
The other reason why people say "backpressure is good" is because they hear that cars (or motorcycles) that have had performance exhaust work done to them would then go on to burn exhaust valves. Now, it is true that such valve burning has occurred as a result of the exhaust mods, but it isn't due merely to a lack of backpressure.
The internal combustion engine is a complex, dynamic collection of different systems working together to convert the stored power in gasoline into mechanical energy to push a car down the road. Anytime one of these systems are modified, that mod will also indirectly affect the other systems, as well.
Now, valve burning occurs as a result of a very lean-burning engine. In order to achieve a theoretical optimal combustion, an engine needs 14.7 parts of oxygen by mass to 1 part of gasoline (again, by mass). This is referred to as a stochiometric (chemically correct) mixture, and is commonly referred to as a 14.7:1 mix. If an engine burns with less oxygen present (13:1, 12:1, etc...), it is said to run rich. Conversely, if the engine runs with more oxygen present (16:1, 17:1, etc...), it is said to run lean. Today's engines are designed to run at 14.7:1 for normally cruising, with rich mixtures on acceleration or warm-up, and lean mixtures while decelerating.
Getting back to the discussion, the reason that exhaust valves burn is because the engine is burning lean. Normal engines will tolerate lean burning for a little bit, but not for sustained periods of time. The reason why the engine is burning lean to begin with is that the reduction in backpressure is causing more air to be drawn into the combustion chamber than before. Earlier cars (and motorcycles) with carburetion often could not adjust because of the way that backpressure caused air to flow backwards through the carburetor after the air already got loaded down with fuel, and caused the air to receive a second load of fuel. While a bad design, it was nonetheless used in a lot of vehicles. Once these vehicles received performance mods that reduced backpressure, they no longer had that double-loading effect, and then tended to burn valves because of the resulting over-lean condition. This, incidentally, also provides a basis for the "torque increase" seen if backpressure is maintained. As the fuel/air mixture becomes leaner, the resultant combustion will produce progressively less and less of the force needed to produce torque.

Does exhaust leakage result in more fuel consumption? If it does how?

HI. In a way, yes. The increase is slight and not very much. it all depends on how you drive your vehicle under this type of condition.

Basically; the nature of a modern exhaust assembly is very restrictive, due to the emissions standards of today's laws. When a exhaust leak occurs, this will cause a slight relief of the restricted nature of the system, thus, allowing the engine to "slightly" breath a bit more. This state will increase the HP rate, slightly, thus, causing a small increase in fuel consumption. It will also cause the sound of the exhaust system to increase, slightly, as well.

The increase of HP and fuel consumption is very small, and it will not be noticed. You may only notice the difference in the sound of the engine, but that is about it.

I have a dayton kitchen exhaust blower mod no. 4hz65, 1/25 hp, 1550 rpm, 115 volts, 1.5 amps, 8 inches. it does not seem to do the job, do i need a stronger one?

Remember air will only move as fast as the size of the exhaust pipe in relationship to the fans ability to push. Make sure yours is the proper size for the fans volume.

How much more hp would i get with headers and new system

Headers and a freer flowing exhasut just by itself won't gain you alot of power,maybe 20 horsepower.What is needed is a freer flowing intake and fuel supply along with a better ignition curve to fully take advantage of the freer flowing exhaust.If running fuel injection,you would need a performance chip for the ECU/PCM,to really take advantage of the exhaust system.If running a carburetor,the jets would beed to be increased in size slightly,and a performance curve programmed into the distributor.Think of an engine as a huge iron lung,air in,air out.When you make modifications or improvements to increase the amount of air flow overall,air IN is as important as air OUT.They both need to be adressed is what i'm saying,to take full advantage of any mods.Providing the intake,fuel and ignition are addressed along with the headers and exhaust,expect a good 50 horsepower gain overall (V 8) if not more.Higher gains will require a more radical camshaft,and some driveability will be sacrificed there.
