currently:
V2 w/ 2.62 pulley, headers, exhaust, stage 3 clutch.

plase tell me what I need to improve this setup =) just got paid

well since you lost to an sti that tell me your making less then 256whp when i was boosting 4lbs i beat one by maybe half a fender from a roll. You should be putting down more then that with your setup, get injectors, mevi, piping,emanage and tune. Deff could get a nice increase after those mods. gL

Even if the turbo setup has less peak TQ and HP, the "area under the curve" of the dyno chart is what matters. With the SC, it builds boost linearly and you won't have as much torque in the mid rpm range. This happens in all cars with the centrifugal type blower. Happens with M3 guys too. I tell people the reason why I sold my SC was because it wasn't fast enough and they ask how that's possible when I dyno'd at 265whp (and later 300whp).

Trialt, are you tuned? What does your air fuel look like?

The Ultimate Differential

The Quaife Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster. How?
Simply by getting the power to the ground!

The Quaife differential powers both drive wheels under nearly all conditions, instead of just one.

With an normal open differential, fitted as standard on most cars, much precious power is wasted through wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip - along the path of least resistance.

The Quaife differential, however, does just the opposite. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In cornering, while accelerating out of a turn, the QUAIFE biases greater power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife differential also controls loss of traction when the drive wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife ATB differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife ATB differential's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage, whether you are on the track or on the street.

The Quaife differential is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the cars towards its limits.



Expand your vehicle's limits with the Quaife ATB Differential![/COLOR]

But that is my personal preference. I do think that it is essential for our fwd applications with the desire to make big numbers, to have some type of upgraded differential. In general, the Quaife is a legendary proven mod for the max, whether street or track.

And i know how a torque-biasing differential works, thank you very much.

So what, you don't know WHAT he has under the good. He could be a running a BIG @#$#@ turbo with all kinds of work. You don't know what you are benching against.

If you knew he was stock then yes you would need to figure out whats going on, but for all you know he could be making 500 CHP (not hard for those cars).

OK flipping the script completely:
I take all of that back, because you are reacting EXACTLY how I want people to react when I bust their *** and they go home and see that my Audi only came with 150 HP. Then they think, hmmmmm I know he had an exhaust and BOV and a FMIC, but that still not a lot, something must be wrong with my car ahhahah. As long as they don't see the size of the turbo under the hood.
