Bolting on more go 'n' show
Rarely have we been so wary of a rev limiter. Usually one abrupt cut in power is enough to set a mental benchmark to ensure it doesn't happen again, but Steve Millen's 2003 Nissan Sentra Spec V foiled our senses over and over.
It is not Millen's fault, though. In factory guise, the Spec V's 175 hp peaks at 6000 rpm. Redline is 6200.
Add to its 2.5-liter dohc inline four a cold-air-intake system, header and exhaust system to free up the Spec V's lung capacity and the revs surge even faster.
If you keep a diligent eye on the tachometer, no problem. But we like to drive by the seat of our pants, and let our ears, not gauges, tell us what to do next. Keeps your eyes on the road. Around 4000 rpm, you can distinctly hear the engine's variable valve timing kick up a notch as the intake changes tune to a deep induction growl and the horses start to gallop; our cue to jump hard-er on the throttle.
In even less time, the 6000-rpm peak flashes by with only a 200-rpm window to shift and do it over again. Needless to say, we encountered the fuel cut-off on numerous occasions.
