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

If asking for factual answers and stating a few facts is faning the flames then you might want to keep a fire extinguisher handy! Lol

Otherwise I shoveled dirt on the horse a few post ago..

 

test for you mark go out right now find a safe straight road pick any gear run the engine up to 6800 for 3 minutes straight . Come back and be this thread expert if the injectors you have are sufficient??

Waiting?

opcorn:

 

Other than the fact that you need to read my last post, there is no where around here where I could run high 130s for three minutes.....lol

 

mark I said any gear... or did you not read my last post?

Lets see... ok here we go 17's say 23.5inch or 59.6cm tires in 2nd gear 42 mph @ 6665rpm hmm this is close enough I think we can except your results holding it there for 3 minutes.

really my point is you might think you are safe but I guarantee you are not willing to test it on your MINI or anyone else willing to see if this is correct for that matter?

The injectors you have will not be enough to hold your engine together with this simple test Mark.

Don't do it I am making a point!

and try sometimes not always getting the last word? :lol:

 

He may not have to have the last word but i feel like i will.

This is a picture of a mini cooper piston that was run at max from a roll that obviously blew.
The owner admits to shifting hard and being full throttle but only for however long it took to get from the bottom of second gear to the top of third.
Did the bigger injectors save him? Looks like thats not the case
So now what do you have to say for your self?
Obviously the 550 injectors are not going go save you from engine damage if theirs other factors at play.
case and point is marks car runs fine, he is happy with it and he drives it often. It hasn't blown up nor has my friends 2002 with 130 thousand angry miles on it with a pulley and stock injectors. So now what.
I guess we should resort to what you have done to insure that we dont blow our motors, Sit it on some jack stands and let our friends come over and make engine noises in it.

RAFLMAO

Had a couple words to say after Fergie and the Super Bowl were over but think that pretty much sums up my thoughts!!!

 

Easy fix for this discussion, don't buy them. Do whatever you want to your cars. Run the crud out of them so guys like my mechanic can make money fixing them. The injector experts, manufactures obviously don't know what they are talking about, but the internet warriors here do. minimark is not looking for answers here, he is simply trying to discredit MYNES and anyone else that disagrees with him. Hopefully the mods will step in, after the game, and end the needless intrusions.

 

Jim I don't understand which experts your talking about, if your talking about the injector experts at Mini, BMW, Porsche, Ferrari, etc...? We/I are in complete agreement with them; they choose injector sizes to fit the performance output of whatever engine they are designing..... They do not do a one size fits all approach but select injectors individually for each application.

 

What experts? Are you trying to explain that the factory is the injector experts because if thats true your just shooting yourself in the foot.
Cause they put 340s in the car obviously not enough for a performance application.
I guess i just need some clarification of your hack job of a sentence.
I have not seen Mark try to discredit Mynes just asking some simple questions that no one wants to answer.
Ive got nothing wrong with Mynes.
Though i do need to go to 550 injectors cause i actually need that much fuel.:devil:

 

Hey Nitro, a few pages ago you didn't believe me when I talked about running high RPM's for periods while on a road course and now you want Mark to go make a 3 minute run at max RPM's for some reason.. In what real world application would that fit????
For a comparision get yours off the jack stands and do it yourself. If yours lives then tell us.. I'm sure I can figure out how to blow the engine regardless of what injectors are in it if that is what I want to do for some reason...

 

wow? can anyone here read? READ MY SIGNATURE! :lol:

 

The only thing this thread has now proved is that bigger injectors or the lack there of can cause threads to close till everyone take a few steps back.

 

Lets see if we can bring this back on track please.

A few things to note....

Going over past history about who sold what injector when does nothing. All have learned that bigger injectors are needed when going for more HP. It's really rather simple, more air in requires more fuel.

Doesn't take a brain surgeon to figure that out.

So lets get back to the point and not make it personal. We can have a good discussion if we stick to the facts.

Lynn, take a look at the videos goaljnky posted of his recent track day. Watch the shiftlight. Note how long it is in the orange. That is high RPM running. That will show you that one does live in upper ranges when on a road course. Since your car is off the jackstands and running register for the MINI Thunder event. It is close to you. Drive on track in a spirited manner and learn first hand whats involved in road course work. I expect a full write-up of your experiences please.

Colin - even though jiminni or Lynn posted a pic of jiminni sitting in Lynn's car pulling it into this thread was meaningless and only pissed people off. There was a request to remove that image from this thread. I know that picture is elsewhere on this site and probably other places on the internet, but I'm going to hide behind privacy requests here and edit that image out of your post and the subsequent quote.

Mynes has abandoned this thread, I can't say I blame them as it took a life of it's own far away from the intended direction.

M/A is different, this is a place to discuss with facts not to jump all over each other just because you don't like the direction one tuner or person is going. There is room for all to get their ideas across in a manner that is not insulting to others.

So stop reporting each other when you don't like someone else's ideas or questions. The 3 and 4 year olds I was with at a Super Bowl party last night were better behaved than some of you in this thread. Ya'll know better and the membership as a whole here on M/A deserves better.

Thanks....

deleted as this was to be a pm to Nathan and I might have placed it here instead of to him.............................................................................:lol:

 

Lynn, with all due respect I think the message you try to get across gets lost in the way you write. After a couple of question marks instead of traditional dots you lose me.

On the other side of the spectrum, minimark's agenda is so ridiculously clear that his messages also get lost, regardless of writing style.

There is no need to blindly defend one party or the other. If you sift through the mud, you might realize that there is no real disagreement here, just children bullying other children for no reason other than to say they are right.

It's truly a shame that both parties get into this sh%t slinging match EVERY TIME. Both bring good stuff to the table. I think both blame each other without ever looking in the mirror and recognizing their own (re)actions sometimes leave something to be desired.

I really didn't think this thread was too bad (as compared to others).

 

It has been my contention for some time now that it is possible for more than one party to create a product that works.

 

I still like this site, but I believe I'll go to "read only" mode, with the exception of aerodynamic stuff...

 

OK, what about 2nd gen turbo motor cars?

I'm sure the same factors apply right? More air in means more fuel needed. So if you add a big intercooler, a free-er flowing exhaust and a bigger turbo, blowoff valve and whatever, you need more fuel. Just common sense....

If you're Stock, you're probably OK, unless you're doing track days?

Cause I gotta tell you, around Heartland Park roadcourse, pretty much the only time I'm not at WOT is when I'm on the brakes (oh sure, I feather it here and there), and since I drive an auto trans, I'm not letting up for the shifts, so potentially because a) I'm slower b)I'm not lifting off to shift.... I'm at WOT even more than a stick shift guy, right?

And on a hot Kansas day it'll be even worse right? Except for the intercooler heat soak that causes the ECU to back things off, I suppose....

Yes, I realize it's a different setup but since it's direct injection, would it be even more sensitive?

 

This is more a topic to go to ECU adjustments not this thread but.......

throttle position information sent to ECU= determines through many solutions = position of TB,solution for duty cycle of fuel injectors,timing etc.......So just because you have your foot to the floor.......does not mean 100%

dots...... are for........ doggybags

 

Good question MiniDave. I have not heard of anyone replacing the injectors on the 2nd gen. They must be more substantial as they are high pressure. Might want to give Mynes a call as I know they have been racing the R56.
