Car and Driver April 1992 shows the stock S4 to have a 1/4 mile ET of 14.9 sec at 94MPH.
Turbo Magazine Jan 1996 shows Scott Lampkins stock S4 to have a 1/4 mile ET of 14.98 at 94MPH.
With Hoppen mods and 290HP (Vericom derived), it had a 1/4 mile ET of 14.0 sec at 98 MPH.

Stock S4 versus the Stock 1991 200TQ
Horsepower:
The 1991 200TQ has 217HP @ 5700RPM, The US S4 with 227HP@ 5900 RPM

Torque:
Max Torque is 228 lb-ft (309Nm) for the 1991 200TQ, and *258lb-ft (350Nm) for the S4.

* (Without Overboost) The S4 Engine Management system allows an "Overboost" condition where 2.15 bar max boost is allowed for up to 15 seconds.
The Jan. 1994 European Car Magazine indicates that the Euro S2 which used the S4 engine, makes 230HP@5900 RPM, Max Torque of 258 lb-ft (350Nm) from 1950-3000 RPM. Interestingly, it explains the "Overboost Torque" available is 280 lb-ft (380Nm) from 2100-4000 RPM. The Audi Factory Brochure for the 1994 S2 also shows this overboost torque to be 380Nm @ 2100 RPM
It would appear that the higher torque output over a broader RPM range makes the STOCK S4 quicker in the 1/4 mile than the STOCK 1991 200TQ, even though the S4 is ~200 lbs heavier.

Keep in mind, that when you compare Stage I modified S4's versus the Stage I modified1991 200TQ 20V, the 1991 200TQ 20V will usually have better mid range acceleration in 3rd and 4th gear, due to the different gearing and lower weight.

Weight/HP info

Assume a curb weight (no driver) of 3850 lbs for the US S4 with 227HP and 3650 lbs for the 1991 200TQ 20V

The 1991 200TQ is at 16.82 lbs/HP
The S4 is at 16.96 lbs/HP
The 1986-90 5000TQ/200TQ at 3450lbs would only need 205HP to be at the same lb/HP rating.
The 1995 BMW M3 at 3150lbs with 240HP comes in at 13.1 lbs/HP.
The S4 needs 293HP to meet the M3 weight/HP,
the 200TQ 20V needs 278HP,
the 5000/200TQ needs 263HP.
Automobile Magazine Oct. 1987, Porsche 959, 450HP, curb weight 2977, how does 6.6 lbs/HP sound....

Hmm....Looks like I need to go on a diet.....
