I wonder how much of that was because of insuffiecent OMP injection or the seals or the 3mm. I had to tear down my engine after about 15k because of a broken exhaust sleeve. I had been running the RA seals with the RA adapter for 2 stroke and about 1/3oz/gal in the tank. After about 15k miles I had chatter marks. When I put it back together I doubled the premix in the tank. and mixed 128:1 in the tank. After about another 15k miles I tore the engine down again and the chatter mark were gone. Now I just mix ~75:1 in the tank and call it good.

I wonder what the difference would be between the temp at the sensor and the temp in the rail? Do you have the ability to trim based on fuel temp and can you put another sensor in the fuel rail? More for curiosity than anything else.

I know.... so when are we going to finish up designing our variant and get one cut?

Like John said, it works exactly like the surge tank I built into the fuel cell that I built.

But what about in a scenario like the texas mile, not saying I want to do it, but could this potentially starve if you are flat out for a long period of time?

An Aeromotive 340 is rated at 340lph @ 3B. When operating as a lift pump there is basically zero pressure and the flow will be ALOT more. On the order of 450-500lph I would assume. So unless you're running some MONSTER fuel system, the 340 as a lift pump should run just fine.

EDIT... after finding the flow chart and extrapolating the curve with my calculating eye, it looks like ~ 450/lph
