Hey guys i'm looking for a fuel pressure regulator for my 5th gen accord. I'm looking at probably a aeromotive FPR but i'm not sure. Why i'm getting this is because i'm going to be running a 75 shot of nitrous. I'm only running 55 now.

 

A bit off topic, but instead of starting a new thread..

Can you explain what is a Fuel pressure regulator to me ?

I doubt I need one, since I'm not turbo'ed or have nitrous..

5th gen = 94-97 right ? I got the same one then :]

 

What nitrous kit are you running? Wet or Dry ? I added a fuel pressure riser and found that I needed no extra fuel pressure. I have a stillen FPR and it works good. I'd recommend an AEM FPR.
bLiSS: A Fuel pressure regulator is what determine your fuel systems delivery pressure. A certain pressure is neccessary for the injectors to do their job. The ECU uses the oxygen sensor to determine if the combustion mixture is too rich or too lean. It then adjusts the injector pulse time (in milliseconds) to deliver the precise amount of fuel needed for the load on the engine at the time. When you put bolt on modifications you are generally letting the engine breathe better which is allowing more air into the engine. This leans out the combustion mixture. Sometimes, as in forced induction, you would lean out the mixture too much which would lead to detonation and less power. An injectors pulse is contolled by the ECU. Injectors have a specific flow rate @ the rated fuel pressure. If the engine needs more fuel, the injector pulse lengthens. When the need is greater than can be supplied by the stock setup, then the fuel pressure must be raised to supply more fuel in the same injector pulse duration. The injector pulse duration can only be so long at higher RPMs until the point is reached at which the injector remains open all the time to supply the neccessary fuel requirements. When this is the case it is better to go with larger injectors. They are able to put out a larger pulse of fuel in a smaller pulse duration than the smaller flow injector would at full cycle duty. Anyway a fuel pressure riser raises fuel pressure so the fuel system keeps up with more air flowing in. Unless you have a lot of mods, this would be pointless.
I hope that helps.

 

Don't get the AEM, or Jackson Racing(SAME) one if your setup uses direct bottle pressure to the vacuum on the FPR, or the diaphragm may tear.

 

I'm running a dry shot setup. I've heard alot of bad things about aem FPR and about them blowing. I've never heard of the stillen FPR? Are they pretty good? Where did you get yours from?

 

oh yeah another reason why i need it is because i'm already running lean when i'm using a 65 shot.

 

I got my stillen on from stillen.com . I've run a 75 shot and haven't had any problems with it. The only thing about this one is, it doesn't replace your old fuel pressure regulator. It is added on after it. But it works good.

 

THe only thing that those type won't do is go as low as the AEM one, but why the hell would you want to go to 20 PSI anyway?

 

I think stock is 34-36PSI (at idle) so I don't think you want to go below that.

 

To idle >500cc injectors (VAFC alone wont cut it)

 

i can't find that fpr off of the stillen site. I'm pretty interested in it.

 

Heres the one I'm using. 0 problems with it.

Here is what I use...

 

i like my aem and i run the B and M gauge

 

I really want that stillen fpr now. kteller can you get me a stillen one?
