Im getting ready to order the FIC 95lb high imp drop in ls1 injectors and they have 2 options...single hole tip or 6 hole tip. which one is better?

My setup is
383 ls1
317 heads dual springs
holley hr intake
239/244 .612/.598 115+5
BEP 91mm tubro
4l80 3300 stall

My thinking is 6 hole would atomize better?? is this true? I post over in the fueling section but I was thinking more replies in the FI section for the size of the injectors and being that its a turbo setup....thanks

The idea is that the more holes the better the atomization, though at that large an injector it might not matter since you are just pouring fuel in.

Years ago I used to think the multi-hole provided better atomization - not so much anymore.

After futzing around with several different injectors/injector delay/dyno and fixing high HP car drivability problems by switching to single-point injectors I'm a believer in the single spray (ie. lazer beam) pattern. I think you get better atomization because you are impinging the fuel flow off of the back of the intake valve into the cylinder.

The fan style I think you end up with more impingement on the head wall and thus overall worse atomization.
