I maxed out fic 1000cc injectors with a magnafuel 4303 -10 feed -8 return on e85. Put down 704whp blowing thru the converter. You should be good with 1400cc.

And if you're going that far just grab 160's and be done. These seem to be a hot new item.

I am running Bosch 127's at 60 psi base and at 11.4 afr I am only at 75% idc at 795whp on fuel that tested at a true 85%. The drivability is also great.

I am on Deatschwerks 90Lb (@43.5psi) LS3 injectors with a base pressure of 65psi with E85. Not sure on exact power level but my car sees 125+ 1/8 mile traps @ 3300 lbs! Duty cycle is in the high 90% tho

Just to give you an idea....

I run 120lbs. low imp injectors. Over the weekend, I trapped 142 at 3400 pounds. 55 psi fuel pressure, 13.5 MS pulse width, so about 67% DC. Mid 7 AFR's. Comes out to a little over 700rwhp according to the calculators. Drives like a stock injector.

1000 cc injectors will suffice for 800 rwhp. Having enough pump pushing is the key and you've got that covered with the 2 450s.

Mine are at upper 80s IDC.

Thanks so the Intel appears correct 1500+ should be good.
