Arrow High or Low impendece Injectors?

Im looking to get 1000hp at the flywheel.(91 pump gas w/ meth) I was looking at Siemens Deka 80lbs High Impendece injectors. I know these will be boarder line for my goals. Are the high impendece injectors as good as the low's as far as tunning and performace goes?

Thanks - Ron

80's should be fine... they will likely support 1000 flywheel at 43.5psi base pressure.

Low impedance injectors are faster than high's, but also require more current. In any case it's what your tuner is most comfortable with tuning. Lows with a proper digital driver box and tune will out perform highs, despite what some vendors may claim otherwise.

Higher current = more power = more force opening and closing the injector = faster operation. (In a vary basic manner of speaking!)
