BIGGER is BETTER!!! A FAQ on the Bosch 550cc injectors for R53

that's great news J

so you are saying it has load capabilities just like the Mustang dyno

Right?

 

Look it up for yourself and others as well.... Dynojet Research Inc.- Power Commander, Automotive Dynamometers, Motorcycle Dynamometers, ATV Dynamometers, Jetkits, Wideband Commander, Wideband Commander 2, WB2 so it won't be any he said he said.

 

All right, you two. If you want to discuss dynos, you will need to start a new thread. Know what I mean?

 

I have no reason to start a dyno thread. I don't have time for that. I don't even know why the dyno thing came up in the first place, has nothing to do with injectors. Anyways I am done posting in this thread, I'll let Mike handle here if he wants to. :arf:

 

My point exactly. That should bring us back on topic.

 

Jason, don't let this get you pissed, this is YOUR thread and we appreciate the info

 

Any quick search and consequent contacting of the DYNO manufactures can find some very relieving answers to many questions. The bottom line is "ANY" chassis Dyno is an excellent tool used for tuning!(not ECU tuners but actual professionals that adjust all aspects of a performance vehicle components/parts for maximum potential). All DYNO operators can set the perimeters needed for their particular application. The DYNO wars using chassis Dyno's is old hat on most all car forums and tiresome.

MYNES simply posts before and after of how they use a Chassis Dyno. It is great information if you learn and know how to read a DYNO graph. I recommend to take the time to learn how to fully read and understand a DYNO graph because you would see that some posting DYNO graphs unlike MYNES seem to "tilt" the game a bit with final results in favor of their efforts?


The only true way to measure the accurate output of an engine is with an Engine Dyno. This is as per every DYNO manufacture at least in this country. It is understandable that it is not reasonable to pull an engine from a MINI to use an Engine Dyno to measure mods. But any vendor or supplier claiming to test completed engines or individual engine parts would be offering Engine DYNO graphs showing results of those individual parts on a controlled base line engine. Without a base line engine in the real world of infinite variables true results can not be established as a repeatable norm.

On a technical "note" the use of a flow bench testing fuel injectors and the results will not change on a DYNO of any kind. In other words the injectors gets the information from the ECU and performs the same regardless of where the engine is being run. This means the injectors characteristics are the same in any engine load capacity either on a flow bench or in the engine.
The final spray pattern may vary because of combustion chambers, intake runners, piston shape, etc., etc.,etc. but the flow bench testing is conclusive.

This can be verified through any of the Performance Fuel Injector Manufactures.

 

Thank you for the pm mr. anonymous?

I correct my statement!

Please see that I neglected to have "not just for" included in this sentence.

 

I realize I'm coming into a heated thread late, but I've had an interesting experience reading most of it and a very pertinent question to ask.

A few minutes into reading the thread, I was sold on the idea of getting the new 550cc injectors if I got a tune, even though my mods are relatively small (15%, CAI, Header) for future-proofing, in case I go for a cam and BV head. However...

The video that Mynes posted scared me off promptly. The stock and JCW injectors atomize the fuel beautifully, and every other injector more or less just squirted fuel, including the new 550. Is it impossible to atomize the fuel as well at a higher flow rate, or is it as disappointing a result as it seems to be?

 

What video? The Bosch 550's that Mynes uses atomize perfectly. One of the main advantages of these injectors is that with their tuning you get a very smooth idle.

 

Exactly and thank you very much Mike!!

So why all the BS about spray pattern?

 

Here is why...



So if we look at the video again. You can see the last one on the right is a steady stream with larger droplets.

But Nathan as Mike said, that is in a vacuum and when you add the velocity and I'll add turbulence of the air; the fuel will be atomized very well indeed.

Have you ever peed into the wind, it will be atomized very quickly...lol

 

I guess very well indeed is relative. Very well indeed for pissing in the wind, sure. But for fuel injectors, not so much.

 

I tend to be smart enough to not pee into the wind, learned the 1st time.

I have information coming soon that will help show how all this works. However, it is the start of race season and the guy is busy. So lets all leave it to rest for now.

 

Nathan, never ask you to actually do it again....once is usually enough, at least it was for me..... Lol

 

Isn't the injector on the far right the 440? And the 550 the one next to it?
