Hmmmm I wonder if they will flow what I need?

They will probably flow fine, but in my experience multi hole nozzles like that just don't make power in a 12V. The 4,5, and 6 hole nozzles always dyno the best.

Is there any particular reason the multi holers don't make the numbers that a 5 or 6 holer does?

It has to do with swirl, droplet size, penetration, and in general just plain combustion dynamics.

thats so weird...

i have been thinking about this (lots of holes but smaller) and thinking maybe you could make same power with better efficency

you would think it would help atomize the fuel better

why the emoticon with the 'chuckle'??

why you laughing as you say that?

you are not suggesting that i spend my hard earned cash to try something that you already know does not work are you?

cuz that would be messed up bill

That is funny back in the early 2000's there was another Don. Don~M to be exact who proposed the same thing, and more injector experience than anyone blah blah blah. Anyways "multi holers" were going to be the be all to end all of injectors and he made several sets for 12V and 24V. Well as it turned out these things didn't turn out as planned and didn't make much power. Needless to say Formula 1 aka Don~M don't make multi hole nozzles anymore. All of the raved about "Mach" injectors are of a conventional # of hole design.

Yup, I got a set of one of the first 8 holers for 1stGens. Made lots of power, and smoke, and EGTs (of course, a NWG 12cm hot side didnt help that). Stockers gave me back 1-2mpg, though I probably lost 15-25hp. I was not impressed, to say the least, esp for $800. 5-6 holers for me from now on. Unless I get a 100% money back guarantee.

Depends on how the math is done.

4x20's .00126
4x22's .00152

I used dtanklage's math to come up with those. I could not figure out the other method.

190's are smaller than I/C injectors? I thought they were smaller than N/IC injectors. I know my 93 would make more smoke and more power(more fuel?) than the stockers. Any injector gurus ever dissect a set of 190's? Maybe build a bigger badder 190 style injector? :grin:

Non I/C injectors are bigger than I/C injectors. The 190's are smaller than I/C's. The 190's have more of smaller holes. This atomizes the fuel better, giving more hp and better mileage.
I've never seen a size for 190's, so I can't give an exact dimension.

Just enough power to break everything behind the crankshaft.
