mild steel header??
im looking in to building my own custom header and my question is would 16 gauge (.065in) think mild steel piping capable of taking the heat that a 13b n/a would produce in racing conditions?? and if so how long?? im most likely going to make it out of 304 stainless but i would like to know different options.. since mild steel is alot cheaper but as they say u get what u pay for soo....i dont know
thanks for your time ismael |
Mild steel should work, but in the long run (depending on driving conditions) will most likely crack next to the welds. Racing beat uses mild steel but they use .125" wall tubing.
My opinion smells like all of the others out there, but I think 18ga 304 would provide a long lasting piece and you might even be able to get away with 20ga if you are looking to shave every ounce of weight that you can. Ryan |
Thin mild steel won't survive, go with the stainless.

Mild steel will not last:
http://www.rxracing.com/JulyImages/headercrack1.jpg This was a three year old .120 mild steel header that we built. You can see the previous patch on a crack above the newer crack. -Trent |
Mild steel may work fine on a street car but on a race engine where exhaust temps average much higher, they'll definitely fail in a relatively short amount of time. 304 stainless is nice but 321 would be preferred.
The OBX header is an exact copy of the Pacesetter header execept it is made out of 304 stainless. Although it doesn't look like it, the front runner is almost 8" longer than the rear. |

In those three years the car made it to six events a year, each event with two 20 minute practice races, two 20 minute qualifying races, three 25 minute points races and a two hour enduro. So, say 20+20 + 20+20 + 25+25+25 + 120 = 275 mins per event, x 6 events so, 1650 mins of racing per season or 27.5 hours of racing per season. I also used to drive the car down there and back (3 hours each way). It doesn't sounds like much time, but in the time the header wore out I went through 12 brake rotors.
