Copy that.

Good read in this thread for dolmar/makita guys.

I'm super curious about your staggering of the transfer ports. Can you share your theory on that?

 

[mettee]

Gonna try this

Do you cut wood with that saw, or just keep it on the shelf? Lol
Nice saw.

Oh and dolmar and husky are silly for not putting a nut on the clutch to remove it like a stihl. Rediculous that you need a special clutch tool... that I had to buy.

I talked to a few guys that have alot more knowledge and decided to run them staggared 3 degrees. Suppose to give a wider power band.

They make these uni in dual layer, I'm thinking I'll make a set up for that with an aluminum velocity stack that mates to the HD filter lower boot and elbow. I have a K&n that I got to mess with but I think these foam ones filter more reliably without compromising airflow?

So in theory, you have a target number for the timing, and what you are doing is starting one degree before on the secondary transfers and going to one degree past on the primary transfers?

Set my primaries to open and then 3 degrees past my primaries I open the secondaries

Trimmed a little bit

I think the K&n will filter well as long as you were to also use the filter sock screen they have. It would be hard to beat that performance.

Very cool. Thanks for sharing that. It's a dang good idea I think.

Nice saw.

Freshly ground up rebuild. Got all my stuff from Nate who I highly suggest to anyone. It was super beat up when I got it from home depot. I think I paid 280 for it.

It's gonna eat wood for sure.

Where did you come up with this setup. I'm very disappointed in the stock filter setup and would like this setup.

I haven't ran it enough since porting to give a good review but it seems very strong.

Only one k&n would fit, k&n ru-2550

Then the velocity stack can be turned on a manual machine or cnc. I have one drawn up in solid works.

Tons of room for the velocity section of the adaptor.

Awesome I'll have to check it out

The stock metal spring that holds the HD filter down will hold this part down. Then the filter will secure with the hose clamp.

You might have a hard time finding that exact filter without the chrome top. If so just get the chrome top one you can pull that off. You won't want that metal piece rubbing on the cover.

Just funnin ya. Awesome job on the rebuild. Looks brand new. [emoji106]
Nice filter on it too!

I was apprehensive about using the K&n just because they don't always filter the best, but in my experience with these in automotive apps they do well when they have the mesh sock for dual layer filtering. It's not for everyone unless it actually ends up being heavy duty enough. I use a touch of three bond on each connection so there is no chance to draw in fines.
