2005 evolution fpg

[toomey200]

i heard that the stock evo's are runing 560cc injectors. i want to run 550cc injectors in my talon. will the stock evo fuel pressure reg. work properly on my car with a 255 fuel pump and 550s?

 

[TSIMonsteR]

mmmm... good question. If its possible, definately a cheap solution

 

[v2ner]

Yes...they have 560cc injectors. No, the pump will still overrun it but it will be fine even with your stock FPR. An aftermarket AFPR is not a need while most people will reccommend it.

 

[v2ner]

I reccommend an AFPR if you're a pump gas user. Just so you can raise boost levels safely.

It's not needed to run, but it's needed to run right. The 255 overruns the FPR, not the injectors. Get a FPR with the 255 if you're going to run it. Evo injectors work fine, but get a tuning device.

Guys he is asking if he can run the EVO fuel pressure regulator in his car with the 550CC injectors he wants to purchase.

If the EVO uses 560's, logic would tell me that this should work.

Hooked on phonics worked for me...haha. He said 255 fuel pump.

You should get a AFPR, this is not a recomendation this is needed you will over run your stock one with a 255 and it will not run correctly. This is not just a recomendation v2ner.

There are two separate questions here:

1. Will an EVO FPR fit on the stock rail of a 2G?

According to Buschur Racing it likely won't without some form of modification and even this isn't a guarantee that it would work.

2. Can you run a 255 with the EVO FPR and not overrun it?

Nope, and this is assuming that you could even install an EVO FPR on a 2G. Any time you install a 255, you're subject to FPR overrun without a proper aftermarket unit that can control base pressure and still rise at a 1:1 rate under boost.

Props to the original poster for being creative and thinking outside of the box with respect to using the FPR and injector setup from an EVO. The problem is that you'd still need to tune for the 560's as the FPR only addresses the issue of volume and not injector flow. For an inexpensive Aeromotive kit, take a look at http://www.importevolution.com under the fuel section. I use the pushlock setup and it went together painlessly and works well. Don't forget to add a liquid filled gauge and you're all set.

Hope that helps,

Andy

Do you know anyone who doesn't have an AFPR? Will the car run without an adjustable one, yes. Will the car run right without an adjustable one, it will run fine except for that 5% inconsistent tune which matters as much as the free mods. There are plenty out there that are DD runnin 10s without one. I mean, I don't know his goals but I'm sayin it's not needed but it's good to have one. Yes, there's a difference between a need and a want.

I just have a differnt opinion on that that is all but you know how opinions are like ###holes every one has one, I would say it is needed because it dosent run perfectly with out one but you are correct it can be done.

Having installed a 255 and measured base FP on the stock FPR, I have to strongly disagree with this statement. When you can convince me that 9 psi of fuel pressure increase over stock with no 1:1 rising rate control is a good thing, I'll possibly buy in. Until then, I don't care who runs what. It's poor and shoddy tuning and it wouldn't matter if everyone said it was OK. It still doesn't make it correct. Keep in mind that a 5% inconsistency in a tune can damage internals, especially if one is riding the edge already. That's a chance I'd rather not take.

Simply put an AFPR with a 255 is a must.

 

[v2ner]

Yea, I respect your opinion. It has been done countless times.

I understand what you're saying, but it still doesn't make it right. Besides, this really isn't about opinion (i.e. which turbo is better than another). It's about facts and the fact is that a stock FPR will get killed by a 255.

An occasion when 9psi over stock FP is good thing = when you're running race gas at 27psi on an EVO III. You're a wiseman, you should know why I say this. That is why I reccommend an AFPR for pump gas users. Get what I'm sayin? Don't get me wrong, I'm not a wiseman on DSMtuners. I also have great respect for you.

Yes, I clearly stated it would be overrun by a 255 in a previous post. Even by a 190, right?

 

[andymoraitis]

No worries. You and I are just talking and believe me, we're both being respectful about it.

In all of my tuning experience, the problem that I have with fuel pressure overrun is that I can't establish a linear tune because I won't get a rising 1:1 rate when boost hits. The higher the boost, the more the tune is going to be off. Tuning is all about controlling and changing variables to achieve the best result while keep the motor safe. If I started with a base fuel pressure of 53 and didn't get a 1:1 rising rate out of my regulator, I'd take the chance that the motor would starve for fuel in the upper RPM's, knock like a bi*** and possibly spew the internals everywhere.

Because that particular tuning variable (fuel pressure) will be inconsistent, it throws off every other variable (most importantly the A/F ratio which is critical). Race gas masks the problem because it offers a higher safety margin, but it doesn't solve the issue. I would compare it to trying to establish a tune with four injectors that flowed at vastly different rates.

I run an AFPR for pump or race gas. The type of fuel doesn't matter to me. I just want to know that the fuel pressure I'm tuning around is consistent otherwise I won't be able to achieve consistency in any other part.

See what I mean?

Just like venting the BOV with stock maf? What Andy is saying are not opinions, they're hard facts backed up by numbers. There is a huge difference between "it will run" and "running optimally", would have been more exceptable on a track only car but definitely not on a DD. There is also no good excuse not to run an AFPR considering the cost of gas, the cost of an AFPR would be paid for in no time through better fuel economy.

 

[v2ner]

Uh huh.
