Do you need more flow than 550cc injectors?

I see a lot of people still running the 550 cc injectors still but we all keep adding more and more mods. The 550cc start to get into the danger zone at about 580 RWHP and with our high torque. IMO

I run the 725 cc injector dynamics and they are one of the premium high flow injectors on the market. Many of the exotic cars that make big HP run this style injector and they are known by the tuners, as easy to tune and have good idle characteristics. They list for about $980.00 shipped and I need to go to larger injectors, so need to sell mine with only 2100 miles on them. Below are the specs if you want my set or need larger models, I can get those as well for you.

PM me if you want an almost new set for a great price.

So... 550 CCs good for just under 600whp. The 725 CCs are "too small"? I know you've got something big planned, but damn.

Also, STOP SELLING THINGS I WANT TO BUY!

When you run the fuel flow calculators, injectors can get "to small " fast. What size you say you are running with all those mods and big ported heads you are running?

We all throw more and more power and the fuel system gets taxed quick. Even our stock lines are real small for these HP levels, pumps, injectors and so on.

These are real nice injectors made by injector dynamics and they have a relaly cool " fire hose style stip on them". Not the typical 4-6 hole screen style but a custom machined fire hose tip. Check out their vids online on how the tip sprays.
