Stage 2 for your B8 Audi A4 will be well worth it!

Posted on June 22, 2010 – 3:26 pm

A recent post made by Arin@APR shows some incredible gains to be had with the B8-chassis Audi A4 when upgrading to “APR Stage 2″ using their new RSC free-flow exhaust system.  Still in development, but available to the public VERY soon…

The APR RSC Turboback Exhaust Systems were so free flowing the Engineers were able to make safe calibration changes which resulted in the following:

1. Significantly reduced turbocharger spool time over both stock software and APR stage 1 software.
On the days of testing, stage 1 torque levels at 2400 RPM’s were met and exceded at 2000 RPM’s (400 RPM’s Sooner!) simply by running APR stage 2 software with the RSC Turboback Exhaust System

2. Significantly increased and broadened the torque curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 89 FT-LBS under the curve compared to stock software. Peak torque rose from 267 ft-lbs to 355 ft-lbs, for a 88 FT-LBS peak increase.
-On the days of testing, stage 2 torque levels rose 66 FT-LBS under the curve compared to stage 1 software. Peak torque rose from 334 ft-lbs to 355 ft-lbs, for a 21 FT-LBS peak increase.

3. Significantly increased horsepower, especially the area under the curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 50 HP under the curve compared to stock software. Peak power rose from 212 hp to 248 hp, for a 36 hp peak increase.
-On the days of testing, stage 2 torque levels rose 27 HP under the curve compared to stage 1 software. Peak power rose from 235 hp to 248 hp, for a 13 hp peak increase.

All of our data was collected on back to back runs and are the results of average data. Data was also collected on the same car during several days of testing. Gains between runs were in some cases higher but we have chosen to show you an average of what you’ll expect to see as data can change between runs based on countless variables.

Now for the dyno charts of our development progress!

20-inch wheels and coil-overs should be a B8 A4 standard!

Posted on October 28, 2009 – 10:02 am

Chris is the first to pick up a set of our brand-new 20″ Hartmann HRS4-252-HS Wheels, and the hyper silver finish he chose is perfect for his B8 Audi A4. Chris is experienced in the school of stance and also knew the car would need to hug the 20″ wheels in order to achieve that proper stance and ultimately improve on the car’s handling characteristics for his daily driving needs. The Vogtland coil-over kits are the perfect set-up for street and track driving. These kits combine user selectable height reduction, stiffer springs and properly matched shocks that will improve steering response, reduce body roll and diminish understeer.

As our gallery needs more B8 content, and with other new Hartmann Wheels needing some attention, we would like to thank Chris for giving us the opportunity to take these…

Hartmann’s Mesh 305 Wheels, H&R coils, and APR Tuned B8 A4

Posted on July 13, 2009 – 1:03 pm

Benson drove down from Vancouver, British Columbia in his brand new B8 Audi A4, a trip he planned in a short amount of time after picking up his new car.

The new A4 was to receive brand new H&R Street Performance Coil-Overs, Hartmann’s Mesh 305 Wheels with H&R spacers (15mm up front, 20mm out back) to allow the wheels to sit properly within the A4’s fenders, and APR’s ECU Upgrade for the 2.0TSI.

With wheels and a drop to compliment them, and the added power APR squeezes out of the ECU settings, Benson is already steps ahead of many who have begun B8 Audi A4 modding.

Audi’s recently face-lifted A4 is certainly making its presence known…

Must be B8 Audi A4 week.

James brought us his A4 for a suspension upgrade. A 1.5″ drop both front and rear are a result of H&R’s “sport” lowering spring kit. The drop was just the right amount needed for the car to hug the 20×9″ Privat wheels it rolled in on.

Jacob’s white A4 stood out from the other two white B8 A4s we had in this week as it was the first in a manual 6-speed version, the first in the state we’re told with this exact combination of trim and options. He brought it in to take advantage of APR’s “fully loaded” ECU upgrade.

Jacob had waited months for his new car to arrive, with plans to pick up some BBS CH wheels he had shipped here prior to a KW suspension installation at local tuner Fine Tuning. Expect to see Jacob rolling his new A4 at this week’s upcoming Leavenworth Cruise!

A look at the new B8 Audi A4

Posted on August 28, 2008 – 12:18 pm

Barrier Motors brought by the latest B8 chassis Audi A4 for us to check out – thought we’d share some pictures here with you.

The design of the front-end is very much like the already released B8 chassis Audi A5 and S5, with slight differences to distinguish this model.  The front fascia still includes Audi’s open-grille design and now larger cooling ducts in the lower section of the bumper, giving it a rather aggressive front-end.  The B8 A4 is also 4 inches longer compared to the previous B7 model, and you’ll notice some different body line along the side of the new B8 A4.

And of course the headlight re-design now includes the very familiar white LEDs that really separate the Audi from the rest of the vehicles on the road.

We needed the car here so we can get a brake template made for the car.  Brake templates allow us to determine which of the Hartmann Wheels we have that will fit the car.  Brake-wise, there won’t be any clearance issues however the all new B8 chassis cars have a 66.6 center bore (similar to Mercedes Benz) so our entire product line-up will need to change to accomodate this new hub size.  We will have Hartmann Wheel solutions coming soon, as well as a new B8 Audi A4 section in our online catalog.

The engine bay is certainly different as well… The oil filter relocated up top was one of the first changes easily noticeable and obviously makes for a much easier oil filter swap.  APR is almost ready to release ECU programming for the new 2.0L TFSI motor and we can’t wait to see what kind of power gains we can expect to see for it!

We noticed the battery has been relocated to the trunk, and further below the spare tire (which is not full-sized) and we were happy to see the famed “widow-maker” jack is no longer being supplied.

… And the 125/70-19 spare tire…  Yikes!!

Stay tuned to our online catalog for new B8 A4 products coming soon!!
