I have a question. Reading another post made me think of this...
As I understand it, the advantage of a sequential fire FAST (or any EFI system) vs. a Batch fire system is the injector being fired timed to the cam timing. However, as was pointed out earlier in the other post, it's very typical for an injector Duty Cycle to be over 75-80% at WOT.
Given that, the injector is going to be firing most of the time regardless of cam timing at WOT (at least in the upper rpms).
I suppose I could see a small advantage at lower RPMs where the Duty Cycle is much smaller. So, the injector timing would be closer to the cam timing...
Anyway, just wondering what people think the advantages of the SFI are. I'm not really considering it at the moment, but rather thinking out loud...
Thanx!
