Isn't your car an LS4?

 

That it is. I was just echoing what Ju1ce said. It's a proven middle 13 second platform. An A4 LS1 car isn't that much faster.

 

I agree. Just a couple bolt-ons and they are in the mid 13's easy. Not sure if the SC L67 responds as well.

 

The L67 responds even better considering where it begins. It drops a second and a half on it's quarter mile with 2 mods, headers and pulley.

 

Videos/links of before & after?

 

I'm not going to go search around for exacts. It's well known that proper mods make the cars a lot faster. People who do pullies and catbacks then order a PCM have no idea what's going on.

For every 1 person who makes an L67 car go mid 13's with next to nothing done, theres 50 who spent $5,000 on their car and still run 14's.

 

Thanks for the info. I drove a Grand Prix GTP with pulley, exhaust & shift kit years ago and was quite impressed. The instant torque made it a real blast to drive.
