This is true.

That's cute changing my quote.

Stop acting as if ID is keeping a big secret, and you are doing us all a favor by telling us the truth. Of course it is a modified injector, and the front page of the ID website makes this clear, not a secret as you said earlier. Man, they're pulling some CIA stuff and hiding their secrets in plain site!

The Products

Injector Dynamics fuel injectors are the result of batch testing large quantities of specially modified fuel injectors, and then carefully matching them into sets based on their dynamic flow across the pulsewidth range. The result is vastly superior cylinder to cylinder consistency, even at very low pulsewidths.

Herp derp. They aren't some backwoods drilled out junkers, and there is an incredible amount of waste because so many injectors don't make the cut for quality. Who cares what they start off as? At the end of the day, people are getting a set of injectors that take a shit on the competition. Nobody's drilled out "OH OH the short pulse and voltage offset don't change!!!" miracle budget injectors have a prayer in hell of working as well.

It depends what fuel you are running and the pressure you run the injectors at.

on E85 I'm at 100% duty cycle with 600RWHP and 3bar across the 80lb/hr injectors. . .

Almost no one knows what is done to the injector to make it a 850cc. It is a secret because its so foolish to believe you are getting a injector sprinkled with magic dust. You are simply getting a slightly modified injector with data to go along with it for double the price.
There is no waste. The injectors are grouped into batches that have similar flow. Nothing is wasted. It says so in the quote you posted. The injectors are shipped out of ID to the distributor on a roll of 200+.
Ive heard two versions of the same story. One is that the injectors are bought in a batches of 240+ and only 200 may make it through. The other is that all of them make it but are grouped into batches that are "similar".

The modification to the injector is so simple its downright comical.

DSX · 03-02-2011, 08:20 AM

If the modification is so simple, why don't you just cut the plate off the tip of injectors and sell them? Nobody provides injectors that flow this much that still have superior control at low pulse widths. If you're so quick to bad mouth their stuff, why not take Paul's offer to buy back the ID850s? You clearly are equipped and knowledgable enough to replicate their product, and you already have the raw characterization data from ID, so you can just copy and use that, right?

Generating that data is part of the expense. Please refer me to another aftermarket injector company that is developing the voltage offset and short pulse adder data for injectors.

My quote from their site doesn't confirm anything regarding no waste. You're scraping tha barrel on that one.

Buy modded injectors somewhere else, and here's what you get:

ID does match injectors into batches. Any that deviate from their target range of operation get tossed. That's a fact.

I guess I'm trying to figure out why you're trying to take away from the quality of what they offer when you said you've become quite "found" (I think you meant "fond") of the ID850s.

They call them 850cc at 42.5 psi but our fuel systems run 58 psi which brings them to 1000cc or about 95 lb per hour which should be enough for about 1200 crank HP.

Sweet! Thanks Ted. At least later on when I upgrade short block and heads I won't have to buy new injectors.

These are FAST branded fuel injectors, which may or may not be Lucas or some other crap......stay away

The 850's are a direct drop in, stock height, USCAR connector

jsharp · 03-06-2011, 08:32 PM

I have 60# injectors per livernois but not sure which ones they use!

Supercharged SS · 03-06-2011, 08:37 PM

Ted put a set on my car and at 5900 and I think 650ish rwhp, thats as far as we got due to some serious slippage and throttle body issues, the duty cycle was only at 60% at the psi was near 70. Ted can clear this up tomorrow but they are bad ass.

I'm curious as to which injector would go good with this setup.

The ID1000 would be perfect for my current setup but I really want to just save up for a bigger hp build.. .
