2008 Ford F-250 - Quad Terror

A 1,284hp Ford with FOUR Turbochargers

It all started with a 2 a.m. conversation about how the 6.4L Power Stroke crowd was pushing the performance envelope further than ever before. A few triple-turbo trucks were in the works, so Ford enthusiast Nick Detray told Craig Briggs from Maryland Performance Diesel, “Let’s do four!”
Since more is better, everyone was excited, and fabrication began immediately. The four turbos selected were paired up on each bank: a set of compounds for each side. Nick wanted to have the air capability to make 1,500 hp on fuel, so twin 74mm S400s with BatMoWheels were used as the atmosphere chargers, while two 58mm S200s got the nod for high-pressure turbos. To make sure spooling wasn’t an issue, small 58mm (S200) and 83mm (S400) turbines were used. The exhaust housings are also smaller than normal, with the S400 coming in with a T4-flanged, 0.90 A/R housing, while the S200s feature ultra-tight 0.70 A/R T3 setups.

"How many turbos can you fit under one hood?
The rest of the supporting modifications for the wild turbocharger system are surprisingly few. The engine itself is mostly stock, save for a set of valvesprings and pushrods from Hamilton Cams. The fuel side of things is also mild (compared to the turbo setup), with an AirDog 165-gph lift pump, dual K16 high-pressure pumps, and 100-percent-over injector nozzles from Maryland Performance Diesel.
Since Nick plans to race his truck, the stock 5R110 transmission was swapped for the quicker-shifting 4R100, along with a PCS controller. The transmission was a virtual bolt-in (other than the electronics) and was built with 300M shafts and a 2,000-rpm stall converter by Brian’s Truck Shop so that it could handle the four-digit power the truck was expected to produce.

Outside of the wild engine bay, the truck is pretty much stock, save for wheel and tire upgrades, traction bars, and a custom grille. Mild looks aside, the real fun comes when Nick smashes the go-pedal to the floor. With a dyno-proven 1,284 hp at the wheels and 2,000-plus lb-ft of torque (the dyno was maxed out), it’s clear how much of a monster this truck is. So what’s next? Five turbos? Six? Only time, and Nick’s crazy ambitions, will tell.
