Still not convinced about this 2 fuel pump thing either.....its the metering head thats the limitation, not the pump
Additional to the fact 2 pumps ARE FUCKING RAPING your relay
Rick knows his stuff though so i would look into that personally
theres several of AVA cars running 2 fuel pumps with no hastles,green shed ran 2 pumps,alan knows more about rs turbo's than prob any other tuner out there,he built a turbocharged cvh before ford even had the plans for it,he's been there done that so no one can question alans knowledge,if karl norris or stu used 2 fuel pumps on any of there cars they done then im afraid people on this board would have a completely different attitude towards it
also both my pumps are wired to seperate relays so theres just the same demand from the relay as it would be from one pump
if i used my car as an everyday car then the low down richness would be a concern but i dont,alans knows that when i drive it its driven hard so why compromise top end fuelling for low down when im very rarely in cruise mode
i dont want this to turn into another tuner wars post,im greatful for rick safechav and fiecos dans input,ill take it on board and talk it thru with alan and see what we can do,i just feel that im not really gettin the best from my set up as it is and could prob see good gains with holding a couple of psi more top end
cheers
