The truck will still be capable of 500 hp on fuel only with the right custom tuning on our F6 chip from DP Tuner, but with the aid of some nitrous and a couple of 45 mm wastegates that WOP installed on the exhaust manifolds, 800 hp was still obtainable. To handle the nitrous needs, a custom three-stage system from NOS was installed. It uses two 10-lb. bottles that are plumbed into one common rail, where three NOS Super Pro Shot solenoids are mounted and then plumbed into the intake tract. The complete system is controlled by the NOS Launcher system which allows us to control and map out our nitrous injection all through an in-cab touch screen monitor.
On our first trip to the dyno with the truck we were pretty pleased to see that our once Goodyear Tire truck made almost the exact power WOP had promised. The truck dynoed 488 hp on fuel only in our chips street tune and with the chip in its highest setting and the nitrous turned on it made a very impressive 798 hp to the rear wheels on Custom Auto's Superflow chassis dyno and 1,018 hp the following week on the DynoJet at Industrial Injection. Not bad for an old outdated Power Stroke platform.
At this point we are more than pleased with our final results. There aren't many trucks in the country that can say they're making an honest 800 hp and even fewer 7.3L Power Strokes in that category. At this point, we finally think we're close to done with the project truck. Now it's time to bolt on some drag slicks and see what it'll do at the track.
