ATI boost question What's the boost rating of the D1SC on a stock LS1 f-body using the ATI crank pulley and the ATI 4.10 blower at 6,000 rpm? If it equals about 5 psi will the stock injectors ( 26.5 lbs/hr ) and fuel pump be fine?

You would be pushing it but you might be ok if you don't take it past 6000rpm. I ran the stock injectors for about a month with no problems but I kept the rpm's down. You might get away with the stock pump. Do you have a fp guage? Make a few full throttle passes after the blower and see if your fuel pressure drops in the higher rpm range.

Damn, i just gave away my 42#svo's to a buddy of mine. I just came up with the idea of bolting on the blower at 5 psi to have some fun before my new engine is built. But another buddy of mine might have a set of 36# injectors i can use. And i will keep the shifts at 6,000 rpm. I can kick myself for letting go of the 42's..lol. Maybe i can talk him out of using them. He's building a 347cid Ford stroker. 42's are probably over kill for his setup. We'll see.
