Another chainsaw dyno...

[Thesandman]

Maybe set them up in the classes that were determined earlier. Seems there was a stock and ported class.

I have a 357 that I smoked one spring in March when I downed several big trees and it then went to 85* plus and I had to get them out. I put a Chinese 359 cylinder and slug in because I couldn't afford a husky 357 set. Now that needs ringed after 2 yrs of use. Trying to decide what way to go. Thanks for answers brothers. Joe, you rock Brother. The new tech dyno is awesome.

Welcome! Without derailing the thread, Husky dropped the price on many of their P/C kits a while back. I will always pay more for an OE cylinder after having some trouble with AM stuff (European). China is a no go here...

Was there a thread that was going to contain all the dyno runs that you couldn't post in being set up? Maybe by David Young?

I ain’t too good at math, but that right there is twenty per cent betterer. Course it’ll be louder too, which is a good thing my book!

I'll print one off for grins and giggles

About the same as a muff modded 2511

Wow. So how much more does a full port job give you???

It is a bit less than that. But I have to use a calculator...



Those are really close to the numbers but I don't have them in front of me at the moment

I was on the wrong line. I thought it went from 4.7 to 5.7. Note to self: Don't math until second cof of cuppy kicks in...

 

[64ps]

the poulan was real close to its advertised hp rating of 2.1..... it came in around 1.8ish.... couldn't get it to rev over 10k

 

[Red97]

2 different engines for sure.
