Hi Guys,
I live in the UK where we don't have any E85 at the pumps. So I run port injected meth. This of course sprays from dedicated meth tanks.
I was wondering now with the spool overdrive kit, how hard it might be to have a second fuel tank, maybe located in the trunk, holding high octane fuel. Either race gas or home made E85. We pay about $11.55 a gallon for ethanol here. It's very expensive so a small supply used on demand would be useful. So with a switch basically have the EKP power a pump located in the second tank instead of in the main tank. This would then flow with a T junction into the same fuel line, through the HPFP and into the injectors. Direct injection does offer many benefits. (So fuel will flow from either the normal main tank or the smaller high octane tank at any one time).
I'm wondering though. How many miles would it be necessary to drive before the high octane fuel got to the injectors, all the way from the tank located in the trunk?
This is just a thought at the moment. My meth kit works well and a secondary tank setup may not be worthwhile. I do have a spare walbro 450 I could use. I'd need to buy the spool overdrive kit. My concerns with that are how long these pumps can sustain 300% or 400% speeds continuously on a daily driver? I can't be replacing $650 pumps all the time.
