[s-cars] Stromung Exhaust, Data?

[Trevor Frank]

So I borrowed one from a very generous, handsome and talented friend...




So I have before and after wbo2 and hp data.... Remarably at the higher
rpm's not a lot is gained, but I still have stock cam's so I suspect
that this is the limiting factor... most notably though is the gain in
efficiency around max torque, so much so that my programming is off,
lots more torque and a bit more hp.... I suspect those who have put on
stromungs with basic programming are running pretty lean around the
torque peak, let say 3-4.5k..   Those with stomung and RS2 exhaust cams
may be in worse shape, I am speculating.    Just goes to show how
something as "little" as an exhaust change calls for a whole new set of
fuel and timing chips.  Boost threshold didn't seem to change much, I
mean I may see a bit more sooner, but I don't get the punch until about
the same rpm that I used to 3k in the higher gears.
