superSucker 1 inch with 4 holes tapering to open plenum gave me 12hp on the dyno- i'll be whittling my own shortly. rick
There's a guy on that auction site we all know and love that makes these; he even bores the ports to you specs. Butch/56sedandelivery.
The old Thermo-quad carbs had the main body made of phenolic resin. Those were absolutely the best performing carb I have ever run, problem is they are a bitch to build and tune. I had this guy, kind of an eccentric, lived in a huge stone house he inherited from his banker daddy. Never had a job but loved old cars. He could rebuild a TQ to better than new and with me running several of them, he was quite handy to have around.
We stock sell a bunch of these in varied configurations. 1 inch, 2 inch, 4 hole, open, etc. About $20 and up. What we have found them most useful for is combating vapor lock on hot rods in the summer time. Nice easy fix most of the time.
We used phenolic spacers on the rockets we launched from the Cape and Vandenber I run a one inch thick right now on my 472 Cad in my 50 Buick and it works great. the material is like a carbon fiber or layered fiberglass very hard and disipates heat.
That is an impressive gain, I just added a K&N prestack to clean up the air and bowl blend inside the air cleaner, I am running a specter 120 low pro will be interesting to see how it sucks.
I used it on my 352 when i saw the gas boiling in the fuel filter after a trip on the highway. Ordered a 4 hole from summit that came with studs for something like 20 bucks. It worked for me.
phenolic spacers what size is the best for street use 1/4" 1/2" or1" i have 3x2 and need help with what is best!!!!
Some cars had timing gears made of phenolic resin in the early fifties. Stronger than aluminum and silent in operation. You could see the weave of the cloth molded into them. It is made of formeldahyde and it is one of the oldest types of plastic, being related to Bakelite. "The phenolic resin gains popularity among manufacturers since it has a lot of benefits which can be taken as good value in manufacturing. The phenolic resin basically has great dielectric strength and really lightweight. Never worry, it will not burden yours. Besides the phenolic has fine machin-ability and also endure from any harsh weather and extreme temperature. The use of resin also can be applied to stand against chemical and corrosion and provide fine automatic strength as well as stability of dimension. Furthermore, the phenolic resins have its unique characteristic of low humid absorption. Related to manufacturing, the phenolic resin can be applied on various parts such as bearings, wear strips, terminal boards, switches, washers, industrial lamination, gaskets, transformers, machining parts, and gears. As a point of fact, the phenolic resin is dense fabrication which is designed by using pressure and heat to cloth of glass or paper layers. Talking about industrial lamination, the layers are made of unwoven fabrics, synthetic yarn fabrics, cotton fabrics, unwoven fabrics and glass fabrics. These materials are effective enough to support industrial lamination. Normally when the pressure and heat are used at once to layers, subsequently chemical reactions force the layers into one and become united. Actually the phenolic material is rare to use by common people since the cost of this product gets higher. There are two other factors which decrease popularity of phenolic resin among customers: first is the brittle nature and the second one is the convolution of production. However certain manufacturing still need the resin as basic materials for certain properties such as saucepan handles, switches, and molded disc and brake cylinders. What’s more, the phenolic resin still plays role in manufacturing with its high functionality."
they used to make circuit boards out of the stuff, now the good stuff is made of epoxy. phenolic is great in high heat situations. aluminum is great to. i think they made army helmets out of it as well.
Phenolic is a plastic product. If it is impregnated in a cloth fabric it is usually called linen micarta.
Dupont Corian [countertop material] also works very well. It is normally found in 1/4" or1/2" thickness is very machineable and will withstand temperatures over 300 F.
