What's on your bench?

I've got some Blue Thunder that I though about using but to chicken to try it. Lol

I saw an earlier convo on ETOH, but it’s getting real now...

Huumm why did I do this and is it going to help with what has planned. Lol. View attachment 139166 View attachment 139167 I think it will.

Why not just remove the spit back cover?
Rather than grinding the slots

It will still provide protection for the filter and still flow better in theory just an experiment.

Looks like go-go juice!

Did you test with and without the spitback guard before drilling up the guard?

FWIW, I would think a Max Flow filter used over the bare cage of that China HD filter you've got would provide more flow and more gains than a little grinding on intake bits.

It’s been tested before. Most 460’s made more power with the spitback cover left over the intake inlet. It suprised a lot of people when it was discovered.

I would try a foam spitback insert in the filter (like the 440’s have) and try that see if it gains or not without the plastic spitback baffle. Just taking it out completely will soak the filter with gas and performance will suffer.

It depends on the saw, some seem to spit back more than others. I would prefer the plastic shield to the foam, the foam is not 100%. (The plastic shield is the newer design, I'm sure they did it for a reason). I believe 044s were available in the late 80s, and the 046 came out in 1995 (or 96 in the USA).

With 440s (or AM 660s w/o the spitback guard) I always make sure the filter is the "same way up", as the spitback is always on the bottom. If you rotate the filter you soon have oil on both the top and bottom. Keeping it only on the bottom improves filter performance (IMO).

The dust sticks to the soaked filter more easily as well, making it pack up faster and only harder to clean.

Now I hope I didn't ruin a good spit back cover. Lol.

My 064 has the foam one 'huumm' I haven't tried using a plastic one it not really sure if one would fit it but I'm with you I would prefer to have the plastic spitback cover over the foam one to me it would be less restricted.

Foam would be less restrictive. Think about it... the air has to make a few 90 degree turns pretty much with the plastic one. Foam is a less convoluted path I guess. Bunch of small holes. Just a hunch... I guess time the cuts between the two with same b/c is the only way to tell for sure.

I disagree with you Mason, going through that honeycomb will slow it more.

Easy to repair with Loctite PL Premium, and does not matter the color won't match, you don't see it!

 

[huskyboy]

This was a easy gain on a 046 I had...

Can’t hurt to time the cuts with both. Only way to confirm.

 

[MustangMike]

2 seconds a cut??? Were you really able to measure a gain from that? (response to two post earlier)
