The Fundamental Steps In Growing The Stock Horsepower In A Ford Powerstroke Engine

The Fundamental Steps In Growing The Stock Horsepower In A Ford Powerstroke Engine

You like your Ford Powerstroke truck proper? They're positively nice trucks and the car of choice for me since they were launched back in 1994. The stock horsepower is okay, however wouldn't you like to have more power, more torque, better drivability, and naturally pick up some fuel mileage? Who wouldn't? There are three very fundamental steps to take to achieve this goal. I'll share right here the speculation and ideas we apply to every diesel performance exhuast pickup that comes into our shop.

The very first thing you'll need to grasp that a diesel engine is nothing more than an air pump. The mechanicals of an engine work very similar to the air compressor out in your shop. One stroke downward of the piston attracts cool recent air in. The following stroke up compresses this air. As soon as the air is compressed, the fuel injector fires fuel directly into the cylinder inflicting the fuel to ignite from the heat of the compressed air. The piston is forced back down again by the increasing fuel burn. Because this downward pressure is what turns the crank and truly creates the rotational power, the stroke is called the power stroke. Once the piston reaches the underside of the cylinder, it comes back up on the ultimate stroke that pushes the exhaust out of the engine. Once we strip away the computer systems, wiring, and seemingly finishless quantity of wires and hoses running across the engine compartment, we can see the engine continues to be a very simple air pump. So let's build on that principle with three fundamental steps that will help that air pump work simpler:

1. We should open the consumption tract in order that the engine pulls air in simpler and cooler.

One of the first modifications it is best to do to your truck is set up some form of cold air consumption kit. Whereas the stock airbox filters air pretty properly, it was solely engineered to circulate sufficient air to feed the engine at factory horsepower settings. Since we are going to up that horsepower, we need more air. Not solely do we want more air, however we need cooler air. A popular modification we see is an open ingredient K&N type cone filter just attached to the tip of the air cleaner hose. While this modification is value effective, we have actually seen a drop in horsepower on our chassis dyno. While the filter flows more air, you are now sucking warmer air underhood air into the engine. The warmer the air, the less oxygen molecules. So we have now negated any reason at all to do the mod with an open to the engine compartment filter.

What we advise, sell, and set up regularly is a cold air consumption kit that sucks it's air from the grill or fender area. When trying on the kits, discover one which has a snorkel sort piece that ends outside the engine compartment. Filter techniques of this type deliver cooler air to the turbo. The cooler the air, the more oxygen rich the consumption air is, the more horsepower we will make when the injector fires. Most cold air consumption (cai) manufacturers declare a forty-50 percent increase of air flow. Most cai kits that suck their air outside the engine compartment have shown an eight-12 rear wheel horsepower enhance on our chassis dyno. Lots of our customers report a 1 mpg increase in fuel economy and far more free feeling engine. Why? Because now we have made it easier for the engine pull air in along with the side advantage of more oxygen rich cooler air. Also we have now lowered our upkeep costs because practically all cai kits have reusable, washable filters.

Now if in case you have gotten excited and started looking for a cai kit for your truck, you may have just gotten overwhelmed by all the choices. Our suggestion for all years of Powerstrokes are the S&B brand intakes. We promote them 10 to 1 over another brand. The match and end is great. We additionally really just like the underhood look as soon as they are installed. And better of all, an entire S&B intake kit could be had for around $270 shipped. That additionally makes them essentially the most economical of many of the kits.

2. We must open the exhaust tract so that the engine can do away with the exhaust gases easier and quicker.

The subsequent step to take is tossing that factory exhaust in the scrap pile. By altering your exhaust to a full four or 5 inch system, you will make it easier for the engine to get rid of the spent exhaust gasses. To illustrate the distinction, seize a stirring straw and a spent bathroom paper roll. Blow via the straw after which by means of the paper roll. Which is less complicated? Which do you suppose your engine would really like higher? Just just like the factory air intake system, the stock exhaust system was engineered to satisfy sound, emissions, and value requirements. Also they have been solely designing a system that might be adequate for factory horsepower levels. Since we're shooting for more than factory, we need to upgrade. If it is all possible to take away the catalytic converter, you should. Relying in your state, it might not be authorized, however the converter is a significant restriction in the exhaust system. When ordering a new exhaust, ensure to check and see if it has provisions for the converter or not. Any system labeled "off-road" will delete it. Just make sure you purchase the fitting exhaust to keep you authorized with the law.

Most producers declare a 15-25 rear wheel horsepower increase with their systems. We now have noticed related results on our Supermovement chassis dyno when testing trucks before and after an exhaust install. Most of our customers report 2-three mpg fuel financial system increases and far freer, faster revving engine. Exhaust gasoline temperatures normally drop on average 150-250 degrees relying on the system. If the engine does not must work as hard to expel the spent exhaust gasses, more of that energy might be transmitted to the crankshaft. Along with a nice exhaust tone we achieve horsepower, torque, and fuel economy.

Once again, if you have cracked the latest diesel journal looking for exhausts you is likely to be overwhelmed by the choices. The sky is the limit here. Relying on the dimensions, model, materials, and the exhaust tip you need, costs fluctuate from $300 to over a grand. Personal preferences will play a task in your decision. We recommend either MBRP or Diamond Eye exhaust systems. You need to be able pick up an aluminized turbo back four" system for roughly $300 shipped. MBRP now has some kits out that have no muffler for a real all out efficiency sound. The sell for around $285.
