Based on comments in other fuel system thread, I thought I would ask for info on mine. I am building an N2o street strip engine. My original intention was to use a surge tank so that when I went racing, I could turn off the pump from the big tank, drain the surge tank and refill it with racing gas. That way I don't have to drain the entire big tank.
However, with all the comments about fuel temperatures, I am concerned that the fuel will heat up too much during the road miles. So my question is- how do guys that run serious N2O use a second tank- as a surge tank or as a stand alone tank that has to be valved into the normal fuel system?
Also- I know a couple of guys on last year's drag week ran second tanks and Larson (so I have heard) uses a split cell. How do these guys switch fuels? Manual valves or a second set of pumps and check valves?
