i was planning on buying a set of #96 injectors but i heard they might be to big to idle at 850rpms.
what do you think?
my plans are big, somewhere around 450-500whp...
i have supporting mods and wanna get the injectors out of the way.
thanks

Tyson,
How big is the cylinder that each injector will supply? If it's 500 cc or bigger, I would think you could make it work with MS-I, and make it work quite well with MS-II.

Has anybody got any sort of calculator that can kick out pulsewidths and duty cycles for different injector flowrates in different sized engines? Anything?

see

It does not address idle and low rpm Pulse Width. It concentrates on the high HP end of injector sizing.

Thanks for the link, I do alreasy have that spreadsheet and it ties up with some I have put together over the past couple of years.
I am more after something that will calculate pulsewidths, I know this is not easy and there are a lot of variables to consider. I guess I'm looking for an online Megasquirt, where the outputs can be read on the screen!
