Great video @StephK87 looking forward to the stock to stock comparisons.

Here is another one I saved back in Feb. Give you idea of stock to stock stuff

Interesting results. 500i must not be broke in yet...

 

[RI Chevy]

Very nice Steph. Thanks for taking the time to do these tests and videos for us.

Different bars, chains and the operator is a joke..... no consistent cutting

Yep some folks have no clue how to do a proper comparison.

Will be waiting on your stock to stock video. I liked what I saw in your last video.

then lets get startet

in honor to the 79er in the video, it has no full squish work done already, just some slight porting with a lowered base (and Bosch stickers instead of the makita one's )

I hope the video is halway enjoyable. As I said, a better and fairer test with some comparable stock saw's is hopefully coming up this week.

Yea she's a little bit slower compared to the modified ones lol

Are the Solo and dolmar also new?
Or are they allready broke in?

 

[usmcbuckwild]

I really want to get my hands on one and see how much difference some mods make to it. Same with the 572

He said modified so I assume that there broken in.

I think seeing how the ports are designed that the 500i should take very well with port mods the thing that might hold it back is will the injection side of it be able to keep up with the mods let's hope.

the injection can push a lot of fuel in to this saw.
There is a option to put a higher pressure on to the pump too.

Looks like I won the bets! That 390 is just a filthy animal. Lol

@nohoff

To create more pressure on the fuel pump: Is there a different spring for the injection pump to boost the impulse signal?

Can you expand upon this?

LOL. You took great risk in that guess sir. Your living on the wild side.

 

[nohoff]

there is a spring in the injection pump which closes the needle when 0.1 bar is reached. You can add a washer under the spring to set the pressure higher.

So Whats the chance we could advance the timing, by playing the the flywheel

Just thinking ahead..

Yes it is a runner that's for sure although I'm a Stihl man I will always have a little soft spot for the Husqvarna a little.lol. but don't be surprised of the outcome when he starts modding the 500i I think it's going to be Sooper close.

No chance as the ECU looks for acceleration/deacceleration of the crank to determine the correct time for the ignition. The flywheel key is only for the first start to start the calibration procedure.
