After almost a year of testing, VF's production forced induction system for the B6/B7 S4 is in my hands. What a work of art!

VF has reported 496 HP and /434 ft/lbs.

Ceramic coated longtube headers

admin — Tue, 01 Dec 2009 18:00:00 +0000

My JHM longtube headers have made it back from Performance Coatings! They've recieved a satin black ceramic coating to dramatically reduce radient heat.

We're looking at a 110-120 degree temperature reduction in the engine bay; this should be good for a 11-12% increase in engine efficiency. Gotta love free horsepower!

For a 450-500HP motor we can expect a gain of 50-55HP. Show me a better mod for the money!

Thanks to Performance Coatings and JHM!

JHM longtube headers have shipped!

I received word from JHM that my longtube headers have shipped. The JHM longtube headers replace the OEM headers and downpipes; other cars have been seeing both 20-50 ft/lbs and 20-50 AWHP gains throughout the powerband. JHM reccomends wrapping the headers with an exhaust wrap, I choose another route.

Performance Coating in Auburn, WA will be coating the headers with their satin black ceramic coating; we expect to see a temperature drop of 110-120ºF.

Read more about the headers on JHM's site.

OEM S6 LEDs an an Oettinger front bumper

admin — Tue, 04 Nov 2008 09:33:29 +0000

Here's all the information you will need if you want to do it:

Parts and approximate cost

$1000 - Oettinger front bumper
$375 - OEM S6 LEDs
$75? - B6 A4 tow hook, washer caps (x 2)
$65 - S6 LED Harness PN: 4F0 940 068 A

You will need misc relays, wires, and switches.

Dimensions

20" long
3" wide
5.5" deep

Expect to spend a LOT for custom fabrication, this is NOT a DIY job. I did not factor paint into the costs either.

The lights are wired to a Bosch relay. When you unlock the car, there's a 12+ accessory. This remains live until the car is locked. The relay has power until the ignition is off, and the car is locked. Essentially, this allows me to have DRLs that turn on when the car is unlocked and remain on until I hit lock.

The power to the lights can be interrupted via a switch in the glove box.

Kerscher sideskirts on the B6 S4

Some photos from the installation of the Kerscher sideskirts. Notice the OEM B6 S4 doorblades don't flow very well with them?
