Nitrous Oxide Regulation System - Nitrous Pressure Games
Once the system was hooked up and all the fittings were doublechecked to be tight, the nano bottle and the nitrous bottle valves were opened. After verifying that no leaks existed, the nano-supplied liquid-filled bottle pressure gauge showed 1,150 psi. | 
Since the nano bottle itself was pre-set to 1,050 psi, the direct and indirect heat that had accumulated in the nitrous bottle had raised the pressure. In order to reduce the pressure to the manufacturer's recommendation of 1,050 psi, the nano bottle valve was closed and the nitrous supply line was loosened until enough nitrous was purged to achieve the target. | 
In addition to verifying that 1,050 psi registered at the nitrous bottle with the nano turned on, an auto Meter Phantom nitrous pressure gauge mounted in the 'Bird's a/C vent was read to verify that both gauges showed equivalent pressure. | 
Upon installation completion, the nano system is quite unobtrusive, and a single bottle will typically support nitrous usage for up to 15 pounds. In addition to being pre-set at 1,050 psi, the regulator on the nano cylinder is adjustable plus or minus 200 psi in 50-psi increments, allowing even further refinement. According to Darnell, "We tell customers that if they want to maintain their current level of performance, they should pill down their nitrous jets by about 20 percent." Although a new nitrous tune isn't mandatory, it's highly recommended if you choose to utilize the same jetting. | 
The subject test car is owned by Larry Morris, a business development manager. Purchased new and now wearing a scant 40,000 miles, the '02 Formula utilizes a 6.0L iron-block motor with Lunati Pro-Mod rods and custom Diamond pistons. Lpe prepared the heads and flowed them to stage ii specs. Real Performance Motorsports installed a custom dry two-stage nitrous system that incorporates NX ice Man Pro solenoids. | 
Each nitrous solenoid is plumbed into a distribution block, where custom steel lines and a proprietary nozzle distribution system spray nitrous into a "Fast toys ram air Box" that gets gulped up and into the induction system. Other than a Walbro 255-lph intank pump and a supplementary Walbro booster pump, custom tuningby rpm and 60-pound msd injectors easily handle up to a 300-shot. | 
Equipped with a th400 transmission and Precision industries 3,400-stall torque converter, the Formula launches off the transbrake and will lift the wheels without any effort. As an aside, numerous track sessions were needed to dial in the suspension package to allow repeatability in testing. Testing netted the Formula a respectable .06-second eighth-mile average improvement, but more importantly, over 2 mph! | | |

The Best You Can't Get
When I first laid eyes on the 2001 Holden SS Ute, I thought I had died and gone to car-guy heaven. Stylistically, it's a cross between a Chevy El Camino and a 2001 Pontiac Grand Prix. Mechanically,...
