In our last issue we took GMC’s Hot Truck and made some appearance upgrades. Continuing along the theme of devilish speed within a budget, we’ve selected race products that offer easy bolt-in installation and apply to many ’99-and-newer GM fullsize trucks. In this issue, we’ll improve upon the Hot Truck’s performance and appearance by installing Holley’s NOS system and SnugTop’s Snuglid.

Our goal with the Hot Truck was performance and style within a budget. Why pay as much as 38,000 greenbacks for a full boogie Sierra, when projects such as the Hot Truck come in at a mere 20 grand? To match the go-fast image on a limited bankroll, we contacted NOS for a full nitrous kit. Holley Performance is the parent company of NOS, so they know how to make motors scream, no doubt about it. NOS recommended a wet fogger system to pump the squeeze into Hot T’s 4.8L motor. The system is a cinch to install and a breeze to operate. It comes with an interior-mounted activation switch, the necessary mounting hardware, a 10-pound NO2 bottle, and various lines and solenoids.

When using nitrous, the engine requires a richer-than-regular fuel mixture, which is administered through a fuel solenoid tapped off the fuel rail test port. Upon engaging, both solenoids open to release a predetermined amount of fuel and nitrous, in a mix or fog, directly into the intake tube. Our system was set for a 100-horse shot. However, different orifice sizes are available to squirt more or less nitrous to the motor.

Since this is a Stepside truck, we wanted to clean up the tail end and cover a newfound friend: the nitrous tank. SnugTop has put the finishing touches on its Snuglid tonneau cover for the new Stepside models. The cover features a one-piece mold and gas-charged shocks for easy opening. As with many SnugTop products, it comes from the factory ready to bolt on, color-matched and all. On the fullsize GM Stepside, the only modification to be made is removal of the rear gate wing; the tonneau has a lip that overhangs the bedrails. After installation we had a safe compartment for our NOS tank and a far, far sleeker truck.

Once the truck had all these goodies bolted up, we just had to take it for a spin. Although nothing of handling or suspension had changed — where the truck would only lay rubber for a few yards before the NOS — with the system engaged, the tires couldn’t hold onto asphalt. As the day closed, the Hot Truck had a safe and lockable compartment for all our goodies. In the next issue, we’ll throw some real ponies into our 4.8L wonder motor. And if that ain’t enough, how ’bout a full boogie suspension drop courtesy of Sleeper Suspension Development?
