shooting for 700 hp what kind of injectors do i need.
my set up is fully built h22 motor and trying to get 700hp, would 1000cc would enough for that kind of horse power or do I need to get 1200 or 1600 cc injectors

With the price difference as small as it is between the 1000 and 1600's, just get the 1600's and then be confident that you'll be able to make the power goal.

The rule of thumb for injectors is 6cc/whp; therefore, you work through your needs in the following fashion.
1600cc inj x 4 (# of inj) = 6400cc (for all injectors)
6400 / 6cc (per whp) = 1067 whp
1000cc inj x 4 (# of inj) = 4000cc
4000cc / 6cc (per whp) = 667whp
I would go with the 1600cc's to be safe. The equations above allow for ~75-85% duty cycle at stock fuel pressure. If you're running E85, you have to use a factor of 1.3 to account for the extra fuel needed. I hope this helps

a B series could probably do it with 1000cc but the H needs more fuel so 1600cc is what you need. my 1000cc's are at 105% duty cycle with 680 hp and an A1000 pump.
the hammer head goes for me.
