2003 Dodge Ram Hemi Engine Modification - 21st Century Hop-UP

The Dynatech headers are as easy to install as any header. Having the inner fender out of the way didn't hurt either.

The Dynatech header system came with everything needed to connect it to the factory system just in front of the muffler. Remember, you will need to cut the factory exhaust before the muffler in order to install the SuperMAXX kit.

From underneath, you can see the Dynatech system fits nicely under the truck and connects easily to the stock system.

It's a good thing that Gary White at White's Automotive is a patient man. When we got the truck running again, we were back at his place wreaking havoc one more time. This time, all our work rewarded us with final numbers of 318 hp and 333 lb-ft of torque at the wheels. That's an improvement of 69 hp and 70 lb-ft of torque. With a little tuning to the computer, the numbers will be higher. Before the parts melee began, we took the Ram to the track, but were disappointed with a 10.16 in the eighth-mile. When the new version hit the track, we were rewarded with a 9.70 e.t. We ran out of time, but are planning to get a proper computer tune-up and hit it again. Stay tuned.

Bumpin' On
When it comes to camshafts, Comp Cams is one of the most recognizable manufacturers in the industry. Not wanting to miss the Hemi craze, Comp Cams came out with their new XFI grind camshafts for Ma Mopar's 5.7 Hemi engine. Three versions of the XFI cams are available depending on your need. According to Comp, XFI (Xtreme Fuel Injection) camshafts for Hemi-powered Chrysler vehicles dramatically increase engine horsepower and torque, yet retain compatibility with all OEM computer systems. The camshafts are application-specific, with designs for street, performance, and towing.

Pulley for You
Underdrive pulleys have been on the market for quite some time, but for you Hemi guys, ASP has introduced a much-asked-for addition. The new pulley from ASP features a 20-percent reduction in size, while maintaining the factory weight to avoid throwing the computer into a tizzy. Keep in mind, this application will require a shorter fan belt (Gates PN K060988). ASP Racing claims this upgrade produces an increase of 19 lb-ft of torque and 7 hp to the wheels.

Dynatech Headers - A division of Afco
Bent Pipes
Ask any hot-rodder what modifications they have made to their vehicle, and you can bet that headers will be one of the mods. A good flowing set of heads won't do you much good if the exhaust is all jammed up, but Dynatech can solve that problem. Their all-stainless-steel SuperMAXX kits feature a 1-3/4-inch long-tube design, with heavy-duty collectors and OBD-II compliant cats. Best of all, the SuperMAXX kits are a direct bolt-in and connect to the factory exhaust in front of the muffler.

KRC Performance
If the mods we have shown here still don't offer you enough added get-up-and-go for your Ram, check this out. KRC Performance has come up with a turbo kit that will more than get your tires fryin'. You can either buy the kit from them and have them install it, or they can ship it to you for self-installation. Now that's the ultimate bolt-on.
