Yes, it was very mildly ported. IIRC, it's only turning 400 RPMs over spec.

BTW, that blower is for sale if anyone is interested. It is in excellent condition, having only been used around my home. I also added a fully adjustable carb. $350 + shipping takes it.

I suppose to get much better performance from a blower, you'd have to put a bigger blower unit on the engine or port it with higher RPM as the end goal.

More rpm would likely yield more air speed, where the larger blower would yield more volume. Of course you need a certain amount of volume or speed means nothing as you have to actually have something to move.. I may be wrong, but I view it like a torque and horsepower relationship.

It's too bad someone cannot come up with a compound compressor or air multiplier. Maybe a screw type compressor could be made compact? However those only compress air and you would have to really overdrive it or have a secondary air mover in order to move the package if compressed air.

I guess you could put a little nitro in it..

I didn't want to increase RPMs too much over spec and risk damaging the fan.

I just picked up a Husky 580 AKA Redmax 8500. I am thus far not impressed with it. Compared to the Redmax 8000 it replaced it's only very slightly more powerful.

Your rep was mistaken.
They are out and in some stores and on youtube videos. Definitely 4 mix, anywhere from 10 to 30 percent more air flow/speed depending on whether your looking at the Australian Stihl site or the US one and BR700 is 10 percent heavier @ 24.6 lbs. Same engine as BR600 just larger fan and housing.

ten days old and many are still commenting on the thread. What is your definition of an old thread and where is the link to the new one? Are you just being confrontational?

It's more than a year old.

Those pesky years...

 

[GrassGuerilla]

So what if it is an old thread? The new post actually made a valid correction. 10 days old, a year old... Big deal. Correction appreciated, ******** about the age... Not so much.

Sorry I must apologize, I'm not reading the year correctly can't seem to learn that I'm in 2016 already.
