Chainsaw Repair

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.
