no tards haha. 100 over is the size of the nozzle. basically, the larger the holes in the nozzle, the faster the injector will empty the fuel. allows the tuner to play with the pulse width to fine tune performance.
for example, i have 190cc injectors with 100% nozzles. they will still flow 190cc's but just empty it faster than a stick with 75% or 50% nozzles. make sense?
Can you use a 100 over nozzle for a 155? Is there any advantage to this as opposed to going with a "straight" 175? I'm looking at what might be best for a strictly towing injector
i haven't heard of larger nozzles for 155's but i don't know why you couldn't. if you're looking for the best tow combo, 155's and a powermax have been a proven set up.
Got the PowerMax and need to dump my current 155s. Got a great deal on a set of Alliant injectors. Need to decide what direction to go with them. If there's no advantage of using a 100 over nozzle to build a 155, I can remove that option from the list.
Last time I talked to Cass, he was finding 75 percent nozzles had better performance wise. I'd look into contacting who ever your gonna go with and see what they say, I loved my 75percent to be honest.
you might as well have typed in a search on nozzles. rating nozzles is a pain in the a$$. and ya 155s come with different nozzles. thats one of the only things that sets them apart from a stocker.
they are just talking %over stock.
Many years ago I opened some injectors to do some investigation for mods. If I remember right the stock had ability to flow 135cc if you plugged a bypass port. Without that port plugged it should only flow about 100cc. That is why I think you see nozzle % increase is to achieve the same flow at different volumes.
