The Process in machining the rail is very complex, Maybe that's why very very few companies ever will attempt it. After we Machine them they are de-burred 3 times with 3 different tools then Polish and inspected at the Machine shop then are Brought to Us sealed, the caps are remove and I inspect every rail with a bore-a-scope for burrs, all threads are check then 2 magnets are used 1 for the line holes and 1 for the feed hole, then they are bench tested at 10,000 Psi for leaks ( it's the highest hydraulic pressure we could use or find for that Matter) The ()version now know Wild was tested at a outside source at pulses pressure as high as 40,000 psi... than cleaned and check and again.
Just recently 1 customer spilled engine coolant on the rail when installing, He immediately contacted Me, I instruct Him that under NO circumstance was he to install it... Now all rails come internally fogged.
At T&C we strongly encourage all with any Type of engine performance Please support it with modding the Rail... . We are Not Providing this mod for the $$$$
We are providing a service and making some $$$ along the way, I will make this statement: I have more $$$ than I can spend, that why rails are $ each, if I raise the Price to $400/$450 you would see many Big name manufacturer offering them.
You will be able to read more about Modding rails in the Mid-summer TDR
Magazine, before and after tests I belive Peirs is doing the Dyno testing, But don't Quote Me on that.
