1,050 HP SUBURBAN

together. Precise tweaks to the injection system, boost tables, and the transmission’s shift strategy make for a wellmannered monster on the street. Even with the 14mm CP3 and 150% over injectors, smoke is minimal, the compound turbo arrangement performs well throughout the entire rpm range, and the Allison’s shifts are firm but not harsh.

CORVETTE-EATING, ECONOMICAL COMMUTER

Without a doubt, the perpetual technological advancements taking place within the diesel industry right now helped drive this build. Thanks to a variable geometry high-pressure turbo able to light things off quickly, an obscene amount of air being flowed up top by the Borgwarner S488 SX-E, arguably the best transmission components you can buy residing in the Allison, and a high-volume fuel system coupled with spot-on EFI Live tuning, Priegnitz’s Suburban pushes the term “daily driver” into new territory. Any time a vehicle has the ability to trap 125 mph in the quarter-mile yet glean 20 mpg out of highway trips, pull a trailer, and be relied upon day-in and dayout, it’s proof that you can still have your cake and eat it too in the diesel segment.

 For efficient power transfer, one of Duramaxtuner’s DT 1000 Allison transmissions is employed. In addition to valve body and pump modifications, the six-speed automatic was treated to a triple-disc billet stator converter from Goerend Transmission, a...

 One of the fundamental elements in the Suburban’s great drivability is the Stealth 64 VVT in the valley. Made by Duramaxtuner, the lighting-quick, factory-based Garrett charger sports a billet 63.5mm compressor wheel, a high-flow turbine wheel, and...

 A FASS 150gph Titanium fuel system satisfies the low-pressure supply needs of a street series 14mm stroker CP3 from Exergy Performance (which is mounted in place of the factory injection pump). Once through the 14mm CP3, fuel makes its way to a set...
