Hi Wilf,
Clearly you haven't got any significant restriction if you're measuring 500hp
Hi Wayne,
Maybe Wilf's got a point: if the dyno says the air filter isn't a restriction, that sounds good to me!
Now both you guys got me curious. When my MPFI is completed, maybe next week, I'll see if I can get a dyno reading on my engine with a 2" high element and a 4" high element, both from K&N. I'll let you know if there's any difference.
Don't hold your breath, though, as my scheduling for the Cobra sometimes is, uh, optimistic
Regards,
Tom
