look up the meaning of "overwhelm" ;)

I don't think I can get much more out of it though. At 20psi boost, and 60psi fuel rail pressure 60-20= 40psi effective...problem is if I try 25psi boost, now my 900cc injectors rated at 43.5psi now only have 35psi of effective pressure. With that inverse relationship going on, you start running into high duty cycles quicker than expected. I guess 400whp is nothing to complain about though! Honestly I don't think I want any more, stuff starts breaking and it can already be scary at times.

At a certain point you must upgrade a LOT of things to keep going. I think that point is somewhere 350-400. Below that, so far at least, I've not had any issues with the setup I posted.

And if you're really making 400 like your VD says, I don't think you'll ever be bored and want more......:party:

:jerkit:

So basically it will increase my base fuel pressure if it overwhelms it. I guess the problem comes when/if it fluctuates like mentioned earlier in the thread. If it overwhelms the stock FPR and raises the base fuel pressure 10psi consistently, than good for me i guess. If it fluctuates than your tune will never be right. Mine is sure holding up fine for now at least.

Subscribed. I'm running the 255HP pump with stock '92 lines and aeromotive AFPR, E10 gasoline. I figured I would have to switch to a new pump and fuel lines to hit my >400rwhp target but the plan is to see if the current fuel system works before spending the money on something that might not be required.

I think Savington replaced the fuel system on Thesus, there must have been a reason. Unless I am getting confused with a trackspeed V8 car.

Gimme a pic of the stock FPR. I'm pretty sure i know what you need, and it costs like... $15 shipped.

Just google. The flat face on our FPR is not the sealing surface, a little clit that goes into the hole on the rail has the sealing oring. I was just going to make a plate like I have on other cars/bikes out of some scrap but it was gonna be too much work for this one.

Right. Same setup as KL and F2T. The adapters are all over Ebay for none of the money.



[edit]

Just saw the pics.

Yep, same piece.

Here's a fancy one. Knockoffs are all over the place if you change your search words slightly.

Where were you last year? :vash: The next problem would be finding an elbow tight enough to clear 99+ intake manifolds.

I'm a little surprised this is new information... these have been out for a LONG time, i've been using them on my MX6 for about... 4 years? KL guys for probably a decade, and Mazda isn't really known for using eleventy billion different regulators.


I actually even used mine as a blockoff plate. Bought that thing, stuck a plug in the threaded portion, then cracked the nut off the end of my rail, which i then threw an adapter to -6 into, ran that to regulator, back to factory return line on firewall. I didn't like the factory FPR placement, how it sat between cylinders 1 and 2.

You mean this tight?

That's gotta be threaded in there. $23 to find out ;)

So hold my hand a little, i think i'm right i just want to double check.

For my 95 engine / fuel rail / FPR i'm going to want this thing

That Ben posted, along with something like this.

From what i understand, that FPR would just adapt to that adapter. But the adapter doesn't say in which means that happens. Is it just a universal? I see the return is -6an and i can choose between -6an and -10an inlet.

Also from what i'm reading about my DW300 pump, is that this regulator should be able to handle it's output. Which at 14.2a will do 100psi.

Lastly, im sure it's possible to connect a -6an line to the stock hardline. Is this a thing that people do? Would would it take to do that(besides the obvious -6an lines) some kind of hardline to braided line adapter?

Flare the hardline to -AN.
