FAQs

What is the most HP you can get out of a 7.3 Power Stroke? ›

How much HP can you get from a 7.3 Powerstroke? On average, a 7.3 Powerstroke engine can deliver about 275 HP, but with modifications, it could reach 300–500 HP!

The 7.3 Powerstroke is a two-valve behemoth which measures in at 444 cubic inches and has a maximum stock power rating of 275hp and 525lb. ft. of torque.

By 2003, the Power Stroke was at the end of its production. In its final year, the automatic transmission provided 250 HP at 2,600 RPM while the standard transmission provided 275 HP at 2,800 RPM. The torque was 505 lb-ft at 1,600 RPM for the automatic and 525 lb-ft at 1,600 RPM for the standard.

Injector Control Pressure Sensor

When an ICP is failing, the engine runs extremely rough as load is imposed (under throttle), and the condition can eventually contribute to a 7.3L's inability to start. Oil contamination in the wiring usually is the cause.

Cold air intakes are a relatively inexpensive way to increase airflow into the engine. This helps turbo efficiency and can lead to gains of up to 15 horsepower. The other method for upgrading your intake system is to get an intercooler upgrade kit like the Banks intercooler upgrade kit for the 7.3 Powerstroke.

When it comes to the best years for the 7.3L Power Stroke, most experts and enthusiasts agree that the 7.3 peaked between 1998 and 2000. The 1999 model, in particular, is considered to be the best of the best.

Bigger Injectors

Aside from adding a chip, a considerable up-sizing of the fuel injectors is mandatory to get any kind of measurable horsepower out of a 7.3L Power Stroke. For us, the only option is to upgrade to a set of hybrid injectors, and specifically the 238cc version for 500hp goals.

An issue with the CPS is one of the most common problems on the 7.3 Powerstroke. On the Old Body Style, the tachometer will move while cranking if the CPS is good. If it doesn't move, then the CPS is the problem. Fortunately, a new CPS for the 7.3 Powerstroke is one of the more inexpensive diesel parts to replace.

Powerstroke Engine Average Life Expectancy:

7.3L400,000-500,000 miles. 6.0L200,000-300,000 miles. 6.7L200,000-300,000 miles. 6.4L150,000-200,000 miles.

If you plan on modifying your Power Stroke or are purchasing a modified version, we recommend staying away from the PMRs. 2001-2003 models were also prone to issues with the exhaust, as well as high engine noise related to the split-shot injectors.

What causes a 7.3 to run rough? ›

There are many reasons why your 7.3 Powerstroke diesel engine might be idling rough or misfiring. Common symptoms can range from a worn-out injector to a bad sensor to stiction in your injectors.

If your 7.3 Powerstroke produces white smoke on startup, but then the vapor dissipates when the truck gets warmed up, the white smoke is likely from unburned fuel. When your combustion temperatures aren't high enough to completely burn off fuel, your engine becomes filled with stiction.

In May 2009, the first Power Stroke to hit 1,000 hp was a 6.0L. Earlier this year, a 6.4L did it as well. But between these two milestones, Mike Ontiveros accomplished the same goal with an engine most thought would never make the cut-a 7.3L Power Stroke.

The "Godzilla" 7.3L utilizes a deep-skirt iron block with six-bolt main caps. Stock engines have 10.5:1 compression and use cast pistons. The forged steel crankshaft has proven to be good to over 1,400 horsepower.

Here you get an idea what happens to 7.3L powdered metal rods at high horsepower. While they can be made to live in the 500-rwhp range with adequate PCM tuning, this image actually speaks to how important custom tuning is on an engine equipped with bigger injectors.
