That's true, but that's ONLY if you have a re-cal or another type of computer to control fuel such as megasquirt. On the stock computer it's a different story.

The RRFPR doesn't work the same way as "any other FPR"..

You brought up the base regulator and then you said something totaly incorrect.

You made this idea in your head that someone here besides yourself is getting these devices "mixed up"

Just reminding you again I and others here actually use the devices so please continue calling me a benchracer who hasnt actually tried these things.

Inadequate being the fact that once you get past 10 psi of boost, your fuel pressure starts to get too high.

47# injectors require a base fuel pressure of around 19-20psi.

The stock computer cant handle that from my experience. Since I am the ONLY person posting here who has actually attempted that Im not sure where you are getting your expertise on the issue.

There is a HUGE difference from taking a 150hp car and making 250hp with a RRFPR (thats what the 12 second car you keep refering to has done)

and taking a 150hp car and making a 500hp car. Instead of a 70% or so incraese in power, Im talking about a 200%++ increase in power.

Call corky right now on the phone and ask him if its reasonable to make a 150hp car run 500hp on his device.

He told me some cars can get away with as low as 12psi base fuel pressure but we cant.

Again, no need to bring the other thread's argument of name calling into this one. If you need to vent then drop me a PM, i get vented at on my job all the time, i'm used to it.

And what did I say that was incorrect? I thought that the point of this thread was to share information? Why do you keep calling me wrong and not explaining on why you're calling me wrong?

And I agree with you, #47 injectors can't be handled by the STOCK computer and I do believe that they may require a base fuel pressure that low.

And I have read and said that the RRFPR will not be adequate for that amount of power since you need to up the fuel pressure so much more on the injectors to make that work. So what are you doing to make the system work? Megasquirt?

If I may ask, could you please post on what the problems with my visions are of this setup? I agree that beyond 8 or so PSI of boost that the RRFPR becomes a bad choice. Other than that I have no idea of why you keep telling me that i'm misled and wrong.

Also if anyone else sees my fault i'd like them to post it as well. I know that I don't know it all, and every time i've been wrong people have told me the correct thing either in a harsh way or a nice way. But the bottom line is that they corrected me, they just didn't leave the subject hanging.

[Ondonti]

I have posted over and over again the incorrect things.

The last thing you said that was wrong was about the base pressure regulators which you admitted and now you seem to forget and want me to remind you again.

Please note above quote for a reference to only one of the incorrect things you said. I have not forgot that in the same post you mocked my intelligence while posting a bunch of bullshit that you admitted was wrong.
Thats like mocking someones spelling and typing your mockery all wrong.

I have been saying this all along and you instead refered to me as a bench racer.
I have actually TRIED THIS im not just guessing.

Calling me a benchracer etc is the problem and you kept the same attitude.
Dont care how much you have read someones website.

You can read my car thread or anyone elses, that wont make you an expert of the things they have had to deal with. The experts are the people who dont need to make threads asking questions on their topic of expertise. Im not one of those people.

[ecs]

You haven't been saying that all along. In the 3.0 turbo thread I was referring to using stock injectors with a RRFPR which is what the older cartech and vortech RRFPR's were made for. They weren't exactly designed to run larger injectors without a re-cal or another type of computer.

And since i've obviously "hurt" ondonti's ego, is there anyone else willing to chime in and correct my mistakes? I welcome constructive criticism with open arms.

i agree w/ these statements but i also think that you may be blaming the fact that you cant get the right amount of power out of your car because of the rrfpr when i think your true problem lies w/ the stock ecu. how many cars out there can increase power 200% w/ the stock ecu? none that i can think of. not w/ out a cal, piggyback or standalone can you do this. i am planning on making 325-375 whp after i build this motor (400+ at the crank) and i also plan on keeping my rrfpr installed. i cant guarantee it will work because i havent done it yet but i am pretty confident w/ my set-up.

Of course Im blaming the stock computer.
With standalone I see no reason to use RRFPR unless I dont have the correct fuel injectors.

[m90daytona]

rrfpr is a "bandaid" on a vehicle w/ the stock ecu but there can be advantages of using it on a vehicle w/ standalone/piggyback. its not a necessity but it wont hurt.

for example, on the megasquirt ecu you are not supposed to drop below 2ms of injector pw. but if you are using huge injectors, it may not idle or it may idle too rich at 2ms. by using a smaller injector and rrfpr you can have a smooth idle and enough fuel under load. some people however are able to get a good idle w/ 1000cc injectors and average fuel pressure. it all depends on the car and ecu.
