Diesel Power - - Dpc ’18 - Words by BRETT T. EVANS Pho­tos by BEN COOPER PHO­TOG­RA­PHY and DIESELPOWER STAFF

KODI KOCH (say “cook”), an elec­tric mo­tor tech­ni­cian for his fam­ily busi­ness Koch’s Elec­tric, isn’t the only com­peti­tor at Diesel Power Chal­lenge 2018 Pre­sented by XDP who has been hard at work get­ting his truck ready for Den­ver. Like many of the oth­ers, his nom­i­na­tion was hard-fought, earned only af­ter painstak­ingly build­ing his ’01 Chevro­let Sil­ver­ado 2500HD over sev­eral years.

Pur­chased in 2015, the truck rep­re­sents Kodi’s first foray into the world of diesel per­for­mance. It was orig­i­nally set up to sled pull with a 740hp 6.6L Du­ra­max V-8 en­gine, but he snapped two rods and trashed the pow­er­plant a few months af­ter pur­chas­ing it. For the re­build, Kodi fo­cused on dura­bil­ity, then swapped out the stock tur­bocharger in fa­vor of a BorgWarner S483 turbo over an S464, al­low­ing the Du­ra­max

to crest 900 hp for the first time.

A first-time en­trant into Diesel Power Chal­lenge, Kodi has worked with DPC alums in the past, us­ing Dmitri Millard’s EFILive ECM tun­ing and Al­li­son au­to­matic trans­mis­sions. Since re­ceiv­ing the call that let him know he would be par­tic­i­pat­ing in DPC 2018, Kodi hur­ried his truck through fi­nal prep, in­stalling a new turbo setup (the old one pro­duced 900 hp and 1,600 lb-ft), big­ger in­jec­tors to take ad­van­tage of the boost, and a re­vised sus­pen­sion setup with coilovers and airbags for greater con­trol. Kodi says these changes should help him per­form bet­ter at DPC.

“It has been a long road lead­ing up to the call, with lots of man-hours and lots of money,” Kodi says. “But it is well worth all the time, and be­ing se­lected to com­pete is amaz­ing. I have been fol­low­ing DPC for a long time, and this has been a life­long dream of mine.”

In ad­di­tion to the prep work he and the rest of the team did to the ma­chine, Kodi has been hon­ing his driv­ing skills since he pur­chased the truck. He has ex­pe­ri­ence hus­tling down the track

at Lu­cas Oil Race­way in Browns­burg, In­di­ana, and Edge­wa­ter Sports Park in Cleves, Ohio. “I think I have an edge since I have been drag rac­ing the truck for sev­eral years,” Kodi says.

Whether or not his skills be­hind the wheel—com­bined with his truck’s promis­ing but un­proven com­pound tur­bos—are enough to hold off the other com­peti­tors will be de­ter­mined when Diesel Power Chal­lenge 2018 Pre­sented by XDP ar­rives in Den­ver.

There’s a lot of hard work and engi­neer­ing un­der the hood, and Kodi’s con­fi­dent his truck will do very well on the dragstrip and in the dyno cell.

A hood-exit ex­haust min­i­mizes back­pres­sure, while a new turbo setup pro­vides the other end of the air equa­tion.

Help­ing keep the 6.6L Du­ra­max fed are dual Fass Fuel Sys­tems 260-gph lift pumps, which sup­ply dual Ex­ergy Per­for­mance CP3 in­jec­tion pumps.

A sturdy rollcage and heavy hit of ni­trous should help when Kodi is hus­tling thetruck down the race­track.

The cushy stock seat be­lies the Sil­ver­ado’s per­for­mance po­ten­tial, with a rollcage and rac­ing har­ness pro­vid­ing plenty of pro­tec­tion to the driver.
