I don't know how you're calculating it but keep in mind usually people run cars like this below 4:1 a/f. Everything I do shows you need more fuel even using a conservative .6 BSFC.
not calcuating, but actuall dyno data , and race pack drag race data...
i usally run the allky turbo engines around the .70 to .72 Lambda
Results shown , with turbo engines , ( mine, AND simular results from travis Quillian ... ex employee of Youngs perfformance...) the lb's per hour is alot less than a blown ( roots and screw ) engine.
Example:
my 355 tt sbc , flowed fuel system , mech injection , meth fuel , uses 4.55 gal / min showing 1400 ish hp
@ 1200 hp it uses ( off the data logger) 4.12 gal / min
even is we double it , to 2400 hp and add some...... 8.5 ish gal / min..
sure,
you can use a 16 gal / min pump to do the job, but why circuate that much fuel round and round ???
yes, you have heaps of pump to play with,
but
the return fuel system fuel lines, valving , etc have to be that much larger, suction that much larger, more chance for airation of fuel ,
Personally i would buy a smaller pump , less initial cost to buy it, but each to there own..
