This set up and FIC 1450's. What is max HP this will support?

 

the same as it would with 2 walbro 255's.

 

the 400s would be pointless with the 1450 injectors

 

If 1450's with two Walrbo 255's can support more than one Walbro 255, and if one Walbro 400 and 1450's can support more than one Walbro 255 and 1450's why cant two Walbro 400's and 1450's support more than two Walbro 255's and 1450's.

 

my #s may be off a little but you get the jist of it.

walbro 255 is good for 500whp
1,450's are good for 600whp
walbro 400 is good for 650whp

you can only flow so much thru those particular injectors, say 300lph. 300 is below 400 and above 255.

 

Makes sense. Thanks.

 

Because your injectors become a limiting factor (choke point) before two 400lph pumps, at that point.
