Ultimately im chasing a 700rwhp car. However the big limiting factor at this stage is the fuel system as I only have an intank Walbro 460 E85 pump. So I'd say the tune will be till thats maxed out. Maybe the 550-600hp mark?
Whats your thoughts on this external setup Lith. Is this surge tank too big?
