sources for preforated sheet

Postby grumpyvette » April 7th, 2009, 8:26 am

if you want to build custom windage screens, oil cooler mount plates,grills, exhaust baffles ,LIFTER VALLEY SHRAPNEL SCREENS etc
perforated steel or aluminum sheet comes in really handy, THE SIZE AND MATERIAL USED WILL NATURALLY VARY WITH THE APPLICATION


theres dozens of sizes of perforated sheet can be used for shrapnel screens or fabricating a windage screen,most sizes, with at least 40% open area should work ok,Ive used very similar looking perforated metal sheet in the past with good results,Image
but look at this chart, I circled the type I used in green notice the percentage of open area vs closed sheet changes a great deal with the pattern and hole sizes selected , for a windage screen or a shrapnel , or windage screen I generally want holes covering at least 45%-50% coverage and at least 1/4"-3/16" in diam. in a windage screen perforated sheet

while I generally use stainless 6 or 8 mesh for shrapnel screens theres lots of options that will work just fine, just remember to keep the oil changed regularly or theres some potential for sludge to clog ANY size shrapnel screens

lowes, home depot and most large hardware stores either carry it or can easily order it, the guys that build custom stereo systems use alot of it and I used to buy it from those guys untill I found it was far cheaper from other sources, btw you can POWDER COAT most steel or aluminum prefforated sheet any collor you choose and its usually not that expensive to do, if you either do it yourself or have a local shop do it for you in a collor they are currently using for a production run

If youve got an excessively loud exhaust theres several ways that you can reduce the sound volume, Ive suggested an (X) pipe mounted as close to the header collectors as clearances allow, as it tends to both reduce restriction and mellow the tone

and you can also mount an (H) cross over pipe

(H) PIPE[/color

just in front of the muffler entrances as that's also been shown to break up sound flow in an exhaust and thats usually a good addition, as it tends to blend and mellow the tone and reduce back pressure further .

NOISE is basically VIBRATION, and in this case the VIBRATION is in the form of rhythmic exhaust pulses, that change frequency with the engines rpm changes
you can either blend and smooth the exhaust flow to eliminate the individual pulses or break up the pulses, or do both, but one trick seldom mentioned thats both fairly cheap and reasonably easy to do is to install a perforated metal baffle in the exhaust ,
Image

lets say youve got dual 2.5" exhaust pipes about 30" long on both side of the car between the rear of the (X) pipe and the first curve, if you were to cut two sections of perforated steel just a bit smaller in width than the inside dimensions of the two pipe,and about 30" long, put one end in a vise and spin the other end of the strip 360-720 degrees so you have a spiral looking a bit like a drill bit
Image
and insert each inside the strait section of pipe it tends to break up sound waves some what

theres also exhaust inserts but I think the smallest is 3" diam.
