~700 hp at the crank with conservative assumptions (0.65 BSFC, 80% max duty cycle)

If you loosen up the assumptions a bit (.60 BSFC, 95% max duty cycle), 875 at the crank.

Personally, I'd rather use the conservative assumptions and have a bit of a safety net, than the opposite.

(and before anyone says that the BSFC numbers are too high, Jonathon is going turbo)

So you say they are enough for 600hp?
My buddys truck has a stock 5.3, isky 212/.561 114 cam, magnum 76mm. And on 15psi he is at 85% IDC with 73# injectora. I was hoping to go 12-13psi on the LQ4.
Ill be runnin a D010, D014, and a D07 nozzle. So 32 gph of methanol.

Think it will be ok?

what pump you running? cause those injectors should out flow a 255 at least my 60's out flowed my 255 walbro. i had to go dual pump to push my 60's full capacity , this all on e85 of course.

nonnie, I think there are some logs in a email from me and you and justin. Check there. on 7psi we did a bunch of logs. If you have old emails, I will look and see if I can find them if you don't have them...... if you think it will help you.

I have those same exact injectors and I am at 95%+ IDC @8psi with Whipple on a stock 6.2. Granted, I'm returnless and my actual rail pressure at WOT is more like 49psi.
