Re: AWD dyno with GIAC,bypass pipes and KN filters
Any ideas how much of the gain is due to each mod? Many, including myself, have been skeptical of the advantage of bypass pipes on a turbo, having seen hp DROPS with bypasses on previous vehicles due to decreased backpressure. Impressive graph, whatever the real cause.
Re: AWD dyno with GIAC,bypass pipes and KN filters
This is only the secondary cat bypass pipes not the main..
I havent seen anyone jsut dynoed with bypass and filters only. I know the GIAC flash suppose to increased 50-60 HP.
they told me 520-530HP, with the 3 combined. If the wheelHP's drivetrain loss is 20% then i shold be at around 528HP, that i dont know for sure...

Re: AWD dyno with GIAC,bypass pipes and KN filters
i am fairly skeptical of any improvement with the KN. other folks with more time on their hands than me (why is it that BMW folks have nothing better to do?) have shown that the KN does nothing in a well designed air intake besides letting in dirt. while i have yet to look at the one in my cayenne-s, the one in the bmw E30 shows these results.

i doubt that the BMW engineers have anything on the porsche guys, and many tests at bobistheoilguy.com show that running KN's gives you high silicon.
