1000 Horsepower
Driving 1000 horsepower with just a push of a pedal is a little difficult for street use. Now, I'm not saying it cannot be done, I'm sure one or two of our readers are currently doing it now (let us know at dteditor@dieseltechmag.com) but most will opt for a little extra nitrous, instead.
Large custom injectors are pretty much the only way to go. These will be specially designed to flow the proper amount for your horsepower level and set up. The down side to large injectors is the fact that they smoke at low throttle and quite extensively at full throttle. To get the fuel to the injectors, a custom race injection pump will be needed. "We use stock and modified parts in our race pump (13mm Stupid Pump) to achieve the big flow," says Wilson. "We will sell the pump to anyone that wants is, but we would like to talk to them and tailor the pump to their needs."
Now that you have the fuel, it is time to address the air. A thousand horsepower requires quite a lot of air and twins are really the only way to go outside of a dedicated competition vehicle. The small high pressure turbocharger should use a compressor wheel around 66/67 mm and the larger low pressure turbocharger will be around an 91 mm compressor wheel.
The engine itself will need to be torn down and the block will need to be surfaced and 14mm head studs installed alone with a block girdle and retainers are a must. "I, also, fly cut the pistons and use a larger cam at this power level," says Hellmann. When asked about how low, most say it depends on the individual truck and what it is going to be used for.
These engines will, also, need to be better taken care of and using premium synthetic oils like Royal Purple will help preserve the internals. Oil changes will need to be done much more frequently and fuel economy should not be of concern; if a thousand horsepower is what you want. The life of the engine itself, also, goes down and the engine will need to be torn down and rebuilt much more frequently.
