Stihl 046 PP475 test 76.5cc
« on: July 31, 2013, 06:58:30 pm »
Wood ash, 14.5" across x 12.5" deep. same square chain and 3/8 7T ran on both.  Both were running fat at 12K due to breaking in with new rings and rebuilds.

046 has wide open dual port muffler with enlarged side exit too. D shaped combustion chamber.

475 stock muffler, no spark screen.

I always considered this 475 a good runner, so that is saying something when this 046 on it;s 1st tank was that much stronger.

The 046 was noticeably stronger in the cuts. 

046  9.32  9.52

475  10.91 10.87

Out of curiosity. I just took the very aggressive 3/8 square chain with lowered rakers that I ran on the DP muffler 440 046 both stock, poulan 445 475, husky 372. I put the 3/8 72dl chain 7T on my EHP redmax 5000 that was built for cutting pulp wood and higher rpm use up to 16.8k for cookie cutting. I have been running it a super fat 13.8k for years now even at gtg's. Not seeing much use in my stable with maybe 5 tanks or so and owner before me put 150 tanks through it in 3 weeks use.
Anyhow cutting the same ash log 14" wide, 13" deep I have been testing the above saws in. The ported redmax 5000 was right there with them in the mid to high 10's.
