In the Diesel world, performance add-ons have grown in popularity as the engines have become more sought after. Over the past decade, truck owners have realized that in order to get more work done the engine must produce lots of torque. Not only does the engine have to produce more torque, but it also must be able to get reasonable fuel mileage. One reason that people steered away from Diesel engines was because of the noise.

Now these engines are very quiet. But, for Diesel applications it has to be reliable and still maintain some level of respectable fuel efficiency. Even if your vehicle is a daily driver, there are still plenty of performance upgrades for the 7. In order to tune a Diesel, you really have to use a chassis dyno.

Gary Stecher of Stecher Performance blasts a pass down the dragstrip with his 7. This truck is capable of running 11 seconds in the quarter-mile. When it comes to chasing more power I recommend sticking with the basics.

When looking into performance upgrades for Diesel engines, you will find plenty of cold air kits and exhaust systems. Those who take it a step further may install some carefully-chosen gauges on their pillar post.

This is a perfect place to start! The cold-air kit is one of the best basic upgrades available. The colder the air, the denser the air becomes. The denser the air becomes, the more air can enter the engine. The more air that enters the engine, the more power the engine can produce.

The fact is that stock airboxes are engineered to minimize noise more than to feed free-flowing air to the engine. It may also be made of better quality materials than the stock part s it replaces.The number one tuning trend has always been car engine upgrades, to boost more power by helping to unleash otherwise wasted BHP potential. This area is arguable one of the most addictive and expensive regions to get involved with and there are always new parts and components available for performance car models, increasing the temptation to buy more.

Careful consideration needs to be taken into consideration to make sure that difference upgrades compliment each other and it might be useful to do research on your given race restriction or what other people have done to similar engines to reap maximum rewards.

While we will not be covering engine swaps here for individual makes and models, we want to cover the basic components to give you a overall idea of what car engine upgrades are available. Most tuning companies will break down a combination of different upgrade components into a upgrade path, consisting of given parts for a rated performance gain.

It is important to have a idea of what the overall aim of the upgrade path is, as some components will affect higher up in the rev range in terms of maximum horsepower, but could effect low down torque figures.

Engines tend to have power and torque characteristics imprinted into them when they are designed and built, and while we can improve these to a certain degree, there are still limitations with technologies, materials and budgets.

Camshafts are a critical part of the engine and are connected to the crankshaft via chains or belts timing belt, timing chainscamshafts are driven by the camshafts and also control the valves. This relationship controls the air to fuel mixtures traditional injection systems and exhaust outlet via operation of the values.

The Camshaft operates these valves by lobes located on the camshaft shaft themselves, as they rotate around pressing the valves downwards. The valves are spring loaded can be pressured air actuated and return to the original location, waiting for the next time the lobes rotate back round, continuing the cycle.

There are both air inlet and exhaust outlet valves and on some engine design like DOHC double overhead cam can have two sets of valves per inlet or outlet. You can imagine that the crankshaft is connected to the camshafts via the cambelt, and the camshafts are connected to the valves, all working in synergy.

In V-type engine configuration, this will mean one cam per head. Exclusively found in V-type engine designs, used to actuate rocker arms to move the valves, with the camshaft located in the engine block. In modern production cars, both trends for more power and better fuel consumption have lead the way in consumers' minds.

A way to accomplish this is but combining two different camshaft profiles to meet both these goal. A camshaft designed for smooth idling speed and high MPG miles per gallon and also a sportier camshaft aimed at more torque, power and BHP.

Engine upgrades are all about multiple decisions that can make or break the performance potential of an car. Nowhere is this more true than in the camshaft department and the wrong choice can hinder the engine characteristics that your trying to achieve. There are a variety of choices in camshafts design and the only real way to differentiate one from the other is by the numbers or specification of each component.

One of the easiest terms to understand, camshaft "lift" refers to how far the valve is opened off the seat, in fractions of an inch.

As the camshaft comes around from the base circle to the lobe ramps, the lifter is displaced and rises, until it reaches the point of peak lift at the nose of the lobe. The amount of this displacement is the actual lobe lift of the cam. The lobe lift isn't the same as the amount of lift at the valve, since this lift is multiplied by the rocker ratio.

The rocker ratio is created because the pushrod side of the rocker is closer to the rocker's pivot point than the valve side. The rockers in most factory V-8 engines ranged from 1.

Usually the lift given in manufacturer's catalogues is based upon the cam's lobe lift multiplied by the engine's original rocker ratio. On the other hand, the "lobe lift" does not include the variable of rocker ratio, and is a very precise number.

The "lobe lift" can be used to calculate the valve lift with any rocker ratio. If after-market rockers with a non-stock ratio are being used, the "lobe lift" multiplied by the rocker ratio will provide the valve lift number. The delivered lift with this cam will be 0. While lift measures how far the valve is opened, duration tells us how long the open cycle lasts.

How long here is given in degrees of crankshaft rotation, fundamentally measured from when the lobe starts raising the lifter, until the same lobe finishes by dropping the lifter back down to the start position.Trade Alerts are FREE updates on topics such as trending hot products, buying requests and supplier information - sent directly to your email inbox!

GM's first-generation Vortec engine was derived from its fuel-injected predecessor, the throttle-body fuel injection TBI.

The differences between them are that the TBI had the injectors right in front of the throttle plate, where the Vortec placed the injectors behind the throttle plate; and the TBI was a speed density system, whereas the Vortec used a mass airflow system to manage the fuel-injection system.

Even though changing the fuel-injection system to a newer mass airflow system was an improvement, it still carried some faults. With the injectors moved out of the air stream, the engine can pull more air, but the two injectors still can't supply or distribute the fuel as efficiently as true direct port injection. The first-generation Vortec was GM's early attempt at an inexpensive port injection system.

The Vortec's two injectors spray fuel into a distribution block. This block has eight plastic hoses attached to it that carry the fuel to the end of each intake runner.

At the end of each plastic hose is a spring-loaded check valve known as a pop-it valve. These pop-it valves open when the injectors pressurize the fuel block and hoses. The run on the Vortec engine was relatively short: It hit the market in and was replaced with GM's new-generation engine line by Due to the short duration and its limited-performance injection system, not many aftermarket companies spent the time or money making performance parts for the Vortec fuel-injected engines.

But, of course, that doesn't completely eliminate it from modifications. In fact, we found your typical filters, intakes, exhaust, and even big-mouth throttle bodies. We contacted Gibson for its dual stainless exhaust system, BBK for a high-flow throttle body and spacer, and Airad for a cotton-gauze filter to see how much power was left on the table.

We dyno'd the engine and gained 9 hp and 12 lb-ft. You can see the dynamometer results: The upgrades follow the engine's powerband, but at higher power numbers. Of course, you can't just buy parts and expect that they will give you great results. Every situation is different and this one had some basic fuel issues.

The stock dyno pulls averaged a The performance upgrades are definitely holding up to their claims.

Even though we find that the performance upgrades provided an increase in power, we know that there is much more to be had with a programmer that would enhance the fuel to accommodate the increased airflow.

The 2. It was available in either naturally aspirated or turbocharged variants with two valves per cylinder. The camshafts and injection pump are driven by duplex chain from the crankshaft.

A separate single-row chain drives the oil pump. The camshaft operated the valves via hydraulic bucket tappets ; valve clearance adjustment is automatic. On many OM engines fuel injection is indirect. A Bosch PES in-line injection pump is used, with a mechanical governor and vacuum-operated stop control. The pump is lubricated by a connection to the engine oil circulation and the fuel lift pump is mounted on the side of the injection pump. Some later versions of the 2.
