My guess would be the torque loss is a result of no exhaust modifications...I'm no expert but I would be willing to bet with at least some exhaust mods to compensate for his additional air intake that you would see similar torque gains. I think at the moment he has too much back pressure, isn't back pressure related to tq in our cars.
I remember when Chris W. tested a 3" highflow cat against a more restrictive aftermarket cat and the 3" highflow showed a loss in torque but with a very slightly increased Hp curve.
Hopefully, with some Tuning and just as many exhaust mods we will be able to see more high end gains. I'm still undecided as to how large of a filter I will be able to get, since I'm working on an AirBox project. It would be interesting to see a K&N Vs comprarable AFE filter dyno!
What do you guys think about Green Filters? I have heard pretty good things about them!
