[/QUOTE]You and Justin should have an email . Let me know if you have questions .. jj[/qb][/QUOTE]jj...still haven't recieved an email yet. Maybe it didn't go through.

Sorry don't mean to bug ya.

Thanks[/QB][/QUOTE]

No problem, your email address keeps giving me :Non-Fatal errors; not delivered, will try again"

PM me with address and I'll send 'em ... jj

.....Worth my while, OK for example if the AFE cost $50, I would think gaining 2 HP would be OK, Say 3 HP for $100. Something like that. At $100, 1 HP would not cut it.[/QB][/QUOTE]

Dan, I agree with you, but the question I had and that was answered by the dyno techs is: "Where/when do you get that 1-2 or 3hp .. if it is just at the peak you may not actually see it ( depending on how you drive)..but the guys at the shop were impressed with the level of gains over a large range (4200 -6750) by simply replacing one good after market filter with another( excellent one) . In fact the greatest gains were not in peak power ... jj

Thanks John for explaining that!!

Dan it must be understood that every case may have a different result as we've seen in the past with other performance products. Any Filter will be on a case to case basis and will totally depend on your modifications, but it was great to get those numbers from John from a mostly bone stock 2000 SVT. If you would like to dyno the K&N and the same size AFE, I'd be glad to assist you in that, we do have a 9" filter you know...

REFUND, Stop being so cheap you dirty RAT

I can't seem to figure out how to post the damn Dyno charts, computer iliterate somewhat!!!

John if you know how to do it try posting it...Mahalo

For those that haven't seen the dyno charts, the power increase is very smooth and steady and can help explain the smooth airflow the AFE provides.

Hey SILLVA I think this is a good opportunity to dispell any myths, give Dan the AFE and no matter what other mods he has if the only thing he changes is a big K&N for a big AFE and he makes MORE power that's all that matters, how much more will depend on his mods your right, but then you have virtually free evidence AND a invaluable second confirmation that yeah this thing is better the holy K&N. If it doesn't then you know to tell AFE they are full of it and Dan sends it back to you and you send it back to them or pawn it off on Ebay.

I look at the potetional sales of a proven product with a non-bias opinion backing it up! Can't go wrong!

Hope you don't mind...

Monsterflow vs. AFE:



So do I get a discount... j/k

Thanks . hope you can decipher these ...
appears as though I need to get some (legal?) exhaust mods .... and the S-AFC to really use the full potential of the C&L and the AFE ... jj

Thanks Justin!!!

The lower chart shows the AFE against the Monster Flow. Obviously the AFE was laying down on the lowend especially in Torque due to the drastic increase in flow. The Monster flow apparently has a fair amount of air entering the passage way and within ECU Range. The AFE clearly has a smoother powerband and doesn't fluctuate like the Monster Flow.

Since I have the ability to Tune on my car, I don't see any lack of Torque whatsoever probably because I'm able to match the fuel to the increase air more accurately...

If you don't understand the Second Chart with Monster Flow and AFE comparison:

*Torque Graph, the Higher Initial Blimp at 2.0 is the Monster Flow, the lower initial is the AFE...

*Horsepower chart, the Higher Initial Blimp at 2.0 is the AFE, the lower initial is the Monster Flow...

Those graphs are confusing in B & W! I do not understand how the Monster flow is supposed to be making more tourque but less HP at low RPM??? I though they were directly related.. And I do not see why a filter that flows better would result in less power down low but more at higher RPM. K&N & KKM gives gains across the rev range. I understand little about A/F regulation by EEC-V but why would the computer be able to compensate at high RPM flow rates but not low??. At face value, both filters give about same area under the curve HP & tourque values (though I would rather have the more useful high RPM power). Micah do you have the dyno showing that A/F tuning was able to compensate for low RPM tourque loss with your AFE?? In view of these dynos, I think that is important.

Offer stands to compare K&N and AFE head to head in a few months.. I want the best filter myself.

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!
