Has anyone here ported their (heaton) blower? Can this process be done by myself or do I have to send the thing out somewhere?
I`d like a little more power and although I like my combo, I`m just looking to make it more efficient.

It can be done yourself. When I did mine I followed the porting directions I've seen on the forum plus ground down on the shelf where the bearings are on the sides. Gives the rotors more area to suck in air. Be careful not to go too far though and make it so the rotors can't seal.

I believe this is where the big power gains are. From what I have seen of the Magnum Powers blower that is what they did. I bet if someone took a picture of the inside of an Apten blower it would show the same thing as well.

 

I can't help but wonder -- what is the downside?

I mean, why would Eaton leave free performance on the table? Couldn't they have cast in the modifications in the first place?

I'm not suggesting that blower porting doesn't work -- it apparently does. But why should this be possible in the first instance?

 

Tim, one reason may be that the area that is being ported decreases the size of the material around the rear bearings.

i would think like the way most things work out, its probably just a cost issue.

 

Tim,

My best guess would be reliability.

I am sure more power is available , but Eaton has to weigh performance to reliability. They are supposed last a long time and I do not hear alot of stories about the Eaton breaking.So I guess they did there job.

I have my blower all apart for porting. .... How far down can I go on the shelf in the back where the two bearings are ?

Does anyone have any pictures of the area I am talking about on a blower that has been ported ?
