Elise Parts also one with a "built in" surge tank.Boe recommends surge tank install in addition to their supercharger setup.
Would swap of the fuel tank itself solve the fuel starvation issue?
Forge Motorsport Fuel Tank - Lotus Elise/Exige
Is the foam in the tank effective in keeping the fuel going
The money is pretty much the same as surge tank and there would be much less potential for leaks or fire hazard.
Also there would be no need of wrangling out stock fuel pump and replacing it with walbro unit.
Not sure if the forge unit has baffles???
...simplicity has merit.
