Echo air filter testing 490 500 4910 501 |

|
Just going to do some real testing for myself. Seen Joe H. Joe |
|
Dyno do this on one of his saws. |
|
I just cant stand the humpback look of the afm wedge deal and |
|
the 3d printed set up. Joe tested this on a stock echo and it |
|
only showed 3% on stock one over the stock air filter. But |
|
guys are saying they are seeing 10% on their ported ones. Going |
|
by cut times. |
|
I'm not doing this because of fines getting by oem filter. |
|
Because I dont have a issue with that since installing a o-ring |
|
over 2 years ago. |
|
I am going to test with cover on oem filter, then with cover off |
|
oem filter, then with the other oem echo set up installed. Just |
|
a good running hack ported 490 to be tested on. |
|
All my 501 are kept stock. Maybe try one of those later on. |

IMHO if you dont have a issues with fines on stock air filter |
|
running the o-ring like I do. Not worth it to me. |
|
Echo 490 that I took on trade years ago. It was hack ported no |
|
squish or base cut. Running stock air filter with oring. |
|
Then running echo parts Joe showed using years back. |
|
Total cost $30 shipped to me for the 3 oem echo parts. |
|
I don�t have issues with fines for over 2 years now just by |
|
running the o-ring in stock |

|
23RS touched up. About half way back |
|
Running my hand down the cut. |
|
Only thing make a smoother cut imo is stoning chain. |
|
Not needed for work saws or chains. |

Retuned for next try. Noticed it had picked up rpm's before last |
|
test session with switch. The 490 500 dont like higher rpm's the |
|
way 501 4910 can compared to those. |
|
Just trying the $30 set up for fun on my 490. |
|
Might try on one of my higher revving 501�s later. |
|
I ended up fattening it up a 1/4 turn on H side to bring it down |
|
some. |
|
10.75 Down, 11 across. Was 1/4"+ down cut shorter then test day |
|
before. |
|
But did get both on video. |
|
Joe's dyno run to show what I am talking about. |
