The fastest 0-60mph for the Series II NA Bonneville was done by Motor Trend of 7.1 seconds and 1/4 mile of 15.5 @ 91 mph. This time actually beat their 225hp Series I and 240hp Series II Bonneville SE SC'd times (note MT tested a Series I Bonne SE SC'd, Series II Bonne SE SC'd, Series II Bonne SE, and possibly an SSEi L67).
My feeling is the avg. Series II NA '98 Bonne can do upper 7s 0-60mph.

Put a higher stall torque convertor and use narrow (read: low rolling resistance/mass) drag radials of proper diameter. Use Air Lift airbags in the rear suspension and pump to 35 psi for min. squat during drag races.
Assuming the NA Series II Bonne can trap 88-91 mph in good tune (please use fresh quality plugs), that'* enough trap speed to support upper 14s with a strong 1.9x sec. 60 foot. Upper 14s on a 90 mph trap is roughly a 6.0 second 0-60mph (e.g. an old 5.0L Mustang by C&D did 6.2 sec. 0-60 mph and trapped 14.8@95 mph and the 5 extra mph helped get the upper 14 vs. a strong launch and 0-60mph for the Bonne with the above setup).
Cold air intake may help but note the airbox on the Bonneville is huge with no elbows like a '98 Grand Prix. So unless other work is done it won't help as much as other CAI applications.

please refrain from adding a performance exhaust to this mid-weight stock NA ride. there'* some potential to lose good low-end that the Bonneville is known for. besides, imagine a noisy bonneville that still runs upper 15s or if the low-end suffers, mid-16s.
the go-fast suggestions i made: premium tune up parts, drag radials, air bags, and higher stall, equate to real measurable results (I'm betting 1 second e.t. difference between a Bonne with CAI and cat-back exhaust and my suggested setup).
Take off the drag radials, deflate rear airbags to 5 psi, and the car drives totally like stock except somewhat lower city fuel mileage. Plus the higher stall will allow you to smoke the tires at will with the traction control off from low speeds.

1. Airbags are not available for our cars, except for the ELC shocks that can be adapted to the car
2. A 1.9 is really gonna be tough to acheive with a NA......
3. A intake REALLY wakes up the NA motor.....i dont know if you have seen but there is that thing called a accordian tube, and the airbox is big, but has many bends....ya that interrupts laminar flow which is what is desired by our cars....hense the MAF Screen

and a higher stall really makes no difference for a stock car..... i can see it on a modded car but not in the stock
and there is more than a .1 difference in teh suggested setups
