VF Engineering supercharger
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
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.

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 ...
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?
