750hp Craig WHY would you want 3 quarts of HOT
OIL in your lap?? If the line breaks you are a cooked driver, racing suit or not. I have the 3 quart under the right side of my car mounted to the frame. I put a shield on the front to protect the tank. If you want a manual valve on it get a T cable from a truck store. It controls the throttle on Fire trucks when pumping. It turns and locks in 90 degrees. They come in all lenghts. You can cut to fit. Hey Craig I heard you where running NOX the tank was the frame.
I couple of the guys have their tanks on the crossmember in the engine bay. Has far as the valve size, the 2 motor builders said that unless you are running 700 cubes that 1/2" valve is OK. What track has the longest sweeper or 180 turn? The amount of time you are in it is 8-10 seconds. Wost of the cobra gang have mild to wild race motors. Mine has
oil limiters in the block and heads to keep the
oil more for the crank and cam areas. When it comes to bearings I think these are the most important. Hope this helps. Have a nice day Rick Lake
