Mod­i­fied ’94 Dodge Ram 2500 gets it done with me­chan­i­cal fu­el­ing

AN­DREW MOR­RI­SON has been work­ing on trucks for as long as he can re­mem­ber. Age 27 now, he has owned more than 100 diesel-pow­ered rigs over the past 11 years. At age 21, An­drew started work­ing at Cum­mins Inc. and was there un­til the be­gin­ning of 2018, when he got a text from McCoy Black (Diesel Power Chal­lenge 2017 alum) ask­ing how he liked his job. One thing led to an­other, and be­fore An­drew knew it, he had quit the cor­po­rate job and started work­ing for McCoy at MB Diesel Per­for­mance.

An­drew has only owned his ’94 Dodge Ram 2500 since Septem­ber 2017, when he and his wife drove 25 hours round-trip from North Carolina to Michi­gan to get it. The truck al­ready had a few mod­i­fi­ca­tions, but the most re­cent up­grades were 13 years old. Know­ing he wanted to try to get into Diesel Power Chal­lenge 2018 Pre­sented by XDP, An­drew started mak­ing changes right away, so he would be able to test the truck on the dragstrip well be­fore the event.

Start­ing from scratch due to how out­dated the previous mods were,

An­drew pulled the en­gine, trans­mis­sion, and ev­ery­thing else down to the brake lines. The truck’s 5.9L Cum­mins en­gine orig­i­nally had a triple-tur­bocharger setup, but he de­cided to go with a smaller set of com­pound tur­bos for bet­ter spool­ing in Den­ver’s high al­ti­tude. All of the changes were made with An­drew dream­ing of get­ting into DPC.

“I am so grate­ful to be one of the 11 cho­sen for DPC,” An­drew says. “There were a lot of great trucks to pick from, and I am just blessed that peo­ple still have faith in an old, me­chan­i­cal 12-valve.”

He also feels very lucky to have McCoy on his team sup­ply­ing knowl­edge and ex­pe­ri­ence.

“There’s a good field of com­pe­ti­tion, but I am con­fi­dent about most of the events,” An­drew says. “I know the trailer cone course may be a chal­lenge due to my truck be­ing a reg­u­lar-cab, longbed with a 12-valve Cum­mins. My en­tire setup is de­signed and built around get­ting into DPC, so I am ex­cited to see how the truck will per­form.”

An­drew says he may not have made it with­out peo­ple who sup­ported and helped him out on his build, so he thanks Fire­punk Diesel, Diesel Per­for­mance Con­vert­ers, EvilFab Diesel, All Shades Cus­tom, Rudy’s Per­for­mance Parts, and In­dus­trial In­jec­tion.

The com­pound-boost­ing process for the 5.9L Cum­mins 12-valve en­gine starts with a BorgWarner S480 tur­bocharger pres­sur­iz­ing air into an S369 SX-E turbo. The charged air then passes through an On3Per­for­mance air-to-air intercooler for tem­per­a­ture re­duc­tion be­fore pro­ceed­ing to a Keat­ing Ma­chine side-draft in­take man­i­fold. Two 45mm Tur­bosmart ex­ter­nal waste­gates keep the abun­dance of boost in check.

The bed is all busi­ness, with es­sen­tials like a ni­trous bot­tle and twin oil cool­ers with elec­tric fans.

The two 240-gph FASS Fuel Sys­tems lift pumps re­ceive diesel from a bed-mounted fuel cell and pump it for­ward to In­dus­trial In­jec­tion’s 13mm P-pump and 5x.022 in­jec­tors. The low­ered sus­pen­sion uses cus­tom ad­justable shocks and Calvert Rac­ing CalTracs trac­tion bars to keep the rear tires planted to the ground.

M&H Tires drag ra­di­als and pol­ished, cus­tom-cut 16-inch Bog­art wheels com­ple­ment the unique black di­a­mond­plate and sil­ver wrap with red skull ac­cents.

The truck’s in­te­rior ameni­ties are min­i­mal. A stock dash, door pan­els, and car­pet are con­trasted by a ratchet shifter, bucket seats, five-point har­nesses, and a roll­bar for drag rac­ing.
