Has anyone compared the noise reduction ability between the Donaldson M070028 & The DynoMax 17224??
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
The specs for the donaldson show a back pressure of 1in of Hg @ 712 cfm. The Multifuel would need to be running 15 pounds of boost and 100% volumetric efficiency to acheive that flow. 1in of mercury is about the same as 1/2 psi. Resitance drops as the square of the decrease in flow and a deuce flows less then half the the lowest cfm on the chart. That puts the backpressure at about 1/8 psi.in theory a straight through muffler has no restriction so no egt gain.
The "Lizard Skin" is just paint with micro-balloons.i know the sound dedener is amn older topic on this post but figured i would share my experience with you guys. i used lizard skin to my mustang. def not as loud as a deuce but have had great luck with it. it sprays or rolls in, if you spray it you can use a cheap spray gun or even buy theres. it dries rock hard and comes in 2 forms sound dedener and head sheild. both can be used together. it is a little $$ 2 gallons covers about 45 sq ft. the sound dedner can handle up to 300 deg and the heat sheild ceramic can handle up to 500 deg. i am pretty sure it can also be painted. the sound control is gray and the heat control is black. can be sprayed out and cleaned. 2 gallons runs around 150-160 here is the link

But where would one get the Kevlar micro-balloons to mix into the paint?The "Lizard Skin" is just paint with micro-balloons.
Make it with any latex you want, in any color you want, for $20 a gallon.
