[QUOTE="chris2000, post: 151490, member: 2862"] Manage to get the filter dyno test done using Dastek Dyno at RS Impressive. Car Used was my totally stock E46 328i. Only mod was the very heavy 17" M-Tech Rims with Falken rubbers 225/45/17 FRT and 245/40/17 Rr. Filter Tested were all from Pipercross UK. 1. Run One was baseline Stock car with new OEM paper filter. 2. Run Two was with Pipercross Venom Shielded Induction Kit 3. Run Three was with Pipercross Open Induction Kit with Shield 4. Run Five was with Pipercross Latest VIS Carbon Induction Kit 5. Run Six was with a Taiwanese copy of the Japan Open Pod - Foam Material Note: Power and Torque given to me was all measure at the engine. Time of dyno was about 5pm and wheather was very hot. All test were down at the same period without removing the car from the dyno machine for more accurate reading.

Now i wonder how restricted the exhaust is?? Anyone want to loan me an exhaust to try?? :D The most power gainer was the Pipercross open pod with 12.7bhp increase over stock but just a mere 0.7 to 1.4bhp other Pipercross filter. The most peak Torque gainer was the NEW Pipercross VIS Carbon kit. In the dyno, you can see the VIS giving a wider and flatter torque among other filter. My assumption is the Pipercross shielded Venom Filter kit should actually work better in real life compared with the open pod, cause dyno was done with bonnet open, and while driving with heat soak, the open pod might lose some BHP compared to the shielded Venom. Then again, the open pod for the Pipercross has a shield too. The biggest loser was the Taiwanese copy. Actually there was no intention to test them, but there was a new unit lying next to the dyno bench and hey, might as well just give it a go and see how they fair as they look really cool with the chrome housing and yellow foam.
