GXP vs WS6?
heck bench racing just shows in the 1/4 mile what the LS1 does all day. a stock GXP would be lucky to get that on a good run and thats at the 1/4..your running on top end. ..the LS1 is just going to make it more relevant.
Like I said bama..either that guy has no clue whats going on and or could not run his bird..or your more than "stock ish" and got soemthing under the hood to pull like that..or both.

but stock for stock the LS1 is going to win.
Of course, I'll still throw in my 2 cents:
Chances are, you'll get OWNED. A stock A4 LS1 F-body will generally run 13.50-13.80 in the quarter-mile. Since the car is an automatic, it's almost a point-and-shoot affair, though it's possible that the driver could screw up and leave the TC on, or simply just light up the tires. This would give you a chance in a short race. On a medium to longer run, even if the WS6 driver makes one of those mistakes, you'd still get run-down on the big-end and blown into the weeds.
Your CAI wouldn't make much of a difference, even if it adds a .10-.15. The fact is, even a strong-running, mostly-unmodded LS4 car will only run 14.10-14.00, with one or two dipping into the 13.90's.
Funny thing is, if your buddy had a 6-speed WS6, you'd have more of a fighting chance, even if his car had some mods. The Bad Driver Mod comes into play a lot more, as the manuals are A LOT more difficult to launch cleanly, and shifting is an artform all his own. There's a lot of room for mistakes, there, and your LS4 is probably quick enough to take advantage of a weak driver shifting his own gears.
For the record, I've owned 2 LS1 F-bodies, a 1999 6-speed Camaro SS, and a 2000 A4 Z28. I know a little bit about how they run!

Still, I'd go race him and see what happens because you never know!
The rest of you can flame away.

The lesson here is, yes, LS4's are very fast for what they are. But in the big picture, it's still a pretty small fish in an ocean filled with predators.
