First off sorry to OP about going off topic.
I have been comparing data sheets on this for awhile ( because I ponder stuff way to much
) and was talking to a racer a few years ago at BG about this very thing. So thought I would share. One thing to consider though is the car NA or blown.
The PVC Hose that is used and mentioned has the following specs. Now I am sure there are different qualities and such but lets just say this.
PVC Tubing mentioned:Chemical resistant but also meets FDA standards and CFR Title 21 parts 170-199. Non-toxic, crystal clear, ozone resistant. Service temperature +25°F to 150°F. Self extinguishing. Heavy wall is kink resistant. Burst pressure 4 times W.P. 72 Durometer. Now compared to this at Mcmaster carr:http://www.mcmaster.com/#5223k25/=pvn3ry Ideal for water, hydraulic oil, oil, and chemicals, such as citric and acetic acids; also for air, smoke, dust, chips, and shavings
Flexible
Temperature Range: -20° to +300° F
Internal Abrasion Resistance: Excellent
Color: Blue or green
Made from PVC-coated foam, this hose withstands high temperatures. Commonly used as vacuum hose, it has a wire support and a smooth interior for unrestricted flow and easier cleaning. Hose also resists crushing and kinking. Can be used indoors and out.
Hose comes in your choice of blue or green. To Order: Please order hose in 5-ft. increments up to the full coil length of 50 ft. and specify color.
Antistatic fittings are gray vinyl with a steel support. Use them to connect hose to your equipment. They slide onto the hose and secure with set screws (included). They eliminate static buildup and ground the hose for antistatic flow.
Hose with antistatic fittings attached comes in your choice of hose color with gray fittings attached. To Order: Please specify hose color: blue or green.
Also we used this once in a project at work seemed to have nice specs...http://www.mscdirect.com/product/48569248?src=pla&008=-99&007=Search&pcrid=15557577904&006=15557577904&005=21882504424&004=4409695744&002=2167139&mkwid=sJXegN7a0|dc&cid=PLA-Google-PLA+-+Test_sJXegN7a0_PLA__15557577904_c_S&026=-99&025=c
