dont see any fuel mods , the single pump (assume its 340/ 255l ) will be maxed before the injectors reach 100% ,
at 80% the pump if healthy should be capable of keeping up and at 80% should support 10.50s at almost 130 with average regal weight of 3550-3600 (fuel only no alky )
if your plans arent low 10s or faster or just for street they should be fine
with razor alky and dual nozzles the 60s have been just into the 9.9s (137mph @1320ft) on a single pump, and just recently a pass of 9.62 143 was done on a single pump with razor alky running 83s but his pump was coming up short as his injectors jumped to 100% to try to maintain AF (running fast with o2 correction) when he should have been ok at only 83% duty if he had the fuel supply up to par (thats approx 68lb/hr per injector so a 60# injector(rated as high as 65lb/hr) would be at max needing over 100%duty and would have come up short and afs would have gone toward lean even if the fuel supply was in place)
these examples imho were on the edge fuel wise , better to have a 20% margin on fuel supply and injectors...
the cost to upgrade the 20% safety factor will seem cheap compared to the cost if you go lean and torch a piston or worse and at that point once you get the motor fixed you'll have to do the fuel/injectors upgrade anyway
personally i like the 75msd or 83s for that turbo and feel better with twins in the tank
