I have a radium surge tank mounted in my trunk and have run the tank completely dry on track. I didn't experience any hint of fuel starve until just a few turns before I completely ran out of fuel. I had a small bobble on corner exit that felt weird, then BAM completely out of gas 3 straights later. had to get a tow truck to pull me in. (at least I took the checker before I ran out of gas.  ) |
The issue with the radium setup is it is not practical for the average track day goer to mount a surge tank in the trunk and it is expensive.
I think what the average guy is looking for is a way to automatically switch on a scavenge pump. Some guys run them on manual switch but they burn out the pump running it at full power the whole time. I think the next step after that is to run it on a small DC motor controller to adjust pump output, you shouldn't need to run the scavenge pump at full duty cycle. Then come up with an auto switching setup. I have a couple ideas in mind but don't have the time to mess with it right now. All in I think I am at 100 bucks for a second fuel basket with pump and sender, a motor controller, and some misc items to the project.
