id like to see the pics please. as far as power im at about 399.xx now. used to be a little more but i sold my boost controler to save my hg till i put another one on in a month or so with the new turbo. im aiming for about 500hp.

ok
i guess i will quote myself then

math should answer that question
255 lph = 4250 cc per minute.. this is at what ever the rated flow of 255 lph is at.
4250 cc per minute max
so we take that number and calculate
(4250cc/min / 10.5 ) / .5 BSFC hp = 809hp MAX at 255 lph. Now keep in mind that if i recall, the 255 lph is a ZERO psi (ie free flow). That number drops with higher PRESSURE.
ninjaedit: thanks the Grand National guys

so with this new information
200 lph @ 45 psi = 3333.33 cc/min
(3333.33cc/min / 10.5 ) / .5 BSFC hp = 634.92 hp.. keep in mind this is CRANK power at 45 PSI now
so one will still be more than adequate.
well, 500 whp puts him at close to 600 crank power. What if one walbro isn't operateing at PEAK effiency..... it wouldn't be a bad idea to have two at that power level for a safety margin. Also....if the power plans change, say you want 50 more hp...... well, then you would need two walbros, so why not?
my belief in walbro.. do it right or blow the engine up and do it again.

Complication
one way check valves and then you must have a way to monitor both pumps for failures.. fun i tell you.
im a very complicated fella. once i achive a power leval and run it for a while i wind up going for more power. just wanted the insight.
