Fuel pressure regulator

How much power could be gained by installing one on my 2.8? Does anyone know wich one is best if any.

Agreed, not much, but if you have a need for an adjustable regulator the Holley one is pretty nice. I don't have the part # handy, but its the one listed for TPI V8 applications.

I'm kinda partial to the Mallory 4309, but that 's a more carb friendly animal.

You know what? I have used them, and a total of 7 times on different vehicles. And no, they do not GIVE much HP. They do help remove lean spots and low pressure areas. THAT is about all they do.

I consider you to not be an "expert" on anything other than irratating people.

Just what nonsense reply are you talking about??? ITS NOT A HUGE GAIN! And I'm as much an expert as anyone else here, having dealt with the one on Redraif's car for three+ years! We've done more dyno runs than any three other people here, with the exception possibly of those members who are producing parts (Doward, Am, etc), and other than smoothing things out a bit it did virtually nothing. I'm not sure why you think that you are the only one here with any knowlege or experience...seems like you'd get tired of stroking your own ego on every post, and insulting other members. Maybe its a contest to see how many times you can get banned, or possibly you have alienated everyone you know and have to come here to have someone listen to you...who fing knows....

I for one wish you and V6 sucker would take your pissing matches elsewhere. The good info sprinkled in with both of your posts are hardly worth the constant namecalling and bs that both of you spew at each other.

The factory manual says it should be between 40.5-47psi with the ignition on (not running). I'd reccomend checking what yours reads with the stock regulator (if you haven't installed the new one yet), and using that as a baseline. Her car had a larger cam ,injectors,and some mild porting when we went with the regulator, so I couldn't give a specific recommendation. I would imagine somewhere in the lower 40s.

Signed, *post removed*

Gee, that was helpful, wasn't it. Lets see if anyone else here can give the correct #'s, because all answers so far are booksmart hearsay and not real world accurate yet.

69 charger, I'll email you privately, these guys are *post removed*. I could give a crap what my car does on a dyno, dyno #'s don't win races. My car does.
if you are so fed up with how you are being treated... why do you keep coming back?

And you also know what? Books are right too. They give specific ranges, that are called "limits and standards". That means that it should fall in a certain specific number range, if it does not, something is wrong and needs replaced.

But you are right about one thing, no dyno numbers do not win races, but they are useful when tuning an engine. After all, if you adjust your pressure up, or down (like you might do for larger injectors), you would not be able to tell if it si helping or hurting unless you got on a dyno to check. That is unless you trust that stupid dash G-tech POS and use that to tune with...

usually 4-5 is about what factory settings can take.

What that means for the person challanged above me...it is a noticiable difference in improvement. What *noticeable improvement * means? It means I have to come into here and list this 18 times in black and white that I could easily feel and tell the difference when I adjusted it up and down. I do not need a dyno to tell the car is running stronger into higher rpms when I turn the pressure up, and then it falls on its face power wise when I turn it back down to normal.

Gee, that was hard to figure out V6 sucker. I have never bought a G-tech meter in my life??? Kid, I am well above your league. You have no comprehension you back woods hick. You want to keep posting crap and antogonise me bvack into here each time to respond? This is the crap the moderators need to weed out yet they ban me for responding and correcting crap, go figure. And as for the # of times I have been banned, there are many moderatorss on here that like me and want me around, and then there are the few here on the V6 board that have a hard-on for banning me.

LT1 or V6sucker, why not both of you come over to one of these other posts I have made recently helping people and shoot your mouths off their about me, see what kind of response you'll get, or what kind of help you can offer? Didn't think so.

And you know what? you are still proiving your "worthiness" to this board by STILL calling people names. And yes it was reported as such.

Maybe because everytime you post in the V6 forums, you are calling names and being abusive.

And as far as the "V6" mods "have a hard-on for banning you" maybe the others should take a look at what you do here, and then they would certainly see things the way we do. They would see your true nature of being an attention seeking, egotisical *****.

I will actually go one farther from just reporting this post, I will also bring it to the admins attention how you have now moved on to calling moderators names for doing their job.

Not to be an A$$ or anything but your basically gonna tell on him? I dont see any point to you guys arguing. One says one the other says something else. Its all opinions, dont argue over whos opinion is right. #23 you car prolly had a better reaction due to your less rotating mass, you others that have tried it or maybe not im not sure do you have mods to your cars or did you just slap it on there thinking it would add power? Again not being rude or anything just asking. Dont fight over worthlessness, just give your opinion or if possible a proven fact. Thanks, Baron
