I bought some injectors from a guy that bought the wrong size and was seeling them cheap. He told me he thought they were 650cc's and i want to put them in my car but want to be sure wat size they are before i do. They are "siemens deka" "mototron" and the part#'sall read different, butthe injectors alllook identical????

Part #'s
One reads: 4211P07690
Another:4211Q02756
Another: 4211P07746
and Another: 4211P07778
It also reads: "INJ-GAS-006" on all 4 of them. I tried looking it up and all it told me was they are "60lb injectors", how many cc's is that?

 

This is a good question. Anybody got a pounds to CC's cross reference chart? I've often wondered this when reading about injectors. What is it, pounds per hour and CC's per minute?
Anyone?
You can probably contact Deatchwerks and ask them how this correlates if no one here knows.

Aww hell I had to go looking.

Gotta love Google.
Here's what I found;

Fuel injectors are really just simple solenoid devices that allow pressurized fuel to be squirted into your intake manifold in a fine spray for a predetermined period of time. Really -- that's all they do. An injector's size is measured in how much volume of fuel it can flow in a given period of time. US Domestic injectors are usually measured in pounds per hour (lbs/hr), while injectors for import engines are usually measured in cubic centimeters per minute (cc/min). You can convert between the two: [hr] [ul]To convert cc/min into lbs/hr, divide cc/min by 10.5. For example, the stock 295 cc/min injectors works out to 28 lbs/hr.To convert lbs/hr to cc/min, multiply pounds per hour by 10.5.

So there you have it. [/ul]

 

So 60 lbs x 10.5 = 630cc
Now you owe me a cup of coffee.

 

damn, thank you alot, how did you find that conversion? I was looking for like an hour for it and i never got the right one. thanks again.

 

You can look up fuel conversion charts on google. I found a couple that way.
