Modified Tuner Shootout - Final Results

We love hanging out with Tony and Jeremy at UMS Tuning so much that we decided to make the dyno competition a two-day affair this year. OK, we also needed to finish early on Friday so we could zip over to Firebird Raceway and have some fun at the Bondurant SuperKart School (check page 48 for more details).

For scoring purposes on the dyno, we decided to stick with our "total horsepower in 100-rpm increments across the best 3000-rpm range" approach. This type of area-under-the-curve measurement tells us the most about the usable power available to the driver when dropping the hammer out on the racetrack, where the engine will almost exclusively operate within its best 3000-rpm range (if geared properly).

We knew World Racing's Scion tC would be strong on the dyno, given the team's background in professional drag racing and Chris Rado's insatiable appetite for horsepower. But what we didn't expect was the eye-watering and throat-burning fumes from the nitro-methane fuel, nor did we expect this monster Scion to literally blow the roof off the place - the upward-aiming front exit exhaust blasting the insulation out of the rafters. It was a hell of a show, even if the exhaust fumes may have caused permanent brain damage. After swapping on the "Punisher" wastegate block-off plate in attempt to generate a little extra boost, the UMS Dynapack showed 899.300 whp and a power-under-the-curve total of 22,861.475 hp, destroying last year's winning score (by FXMD) by more than 4,000 total hp.

Second best on the dyno was Full-Race's R14 (an S14 Nissan 240SX with a full R33 GT-R engine and AWD drivetrain and suspension conversion), its straight-6 singing an intoxicating song while pumping out 687.639 whp and a total power value of 18,185.922.
