FS: Weapon R Rising Rate FPR

[555BCTurbo]

I have for sale a Weapon R Rising Rate Fuel Pressure Regulator...

It is in nice shape, and has a little gauge on the top that reads to 5 Bar I believe.

It works fine, no leaks, I just have no more need for it.

$50 shipped

I'm interested. What is the rise ratio?

[555BCTurbo]

I think it might be 12:1, but I am ultimately unsure...


It seems to raise fuel pressure a lot per PSI though, so that is what brings me to my conclusion.

Let me know if you are still interested

[vrg3]

I am still interested, but still have questions.

12:1 is not unheard of, but is there any chance you can find out the actual ratio?

But you're positive it is actually a rising rate regulator? I have to ask because so many people seem to think that a 1:1 regulator (with or without adjustable base pressure) is an RRFPR.

What kind of fittings does it have? 5/16" hose barbs, I'd imagine? What about the vacuum fitting? A 1/8" hose barb or something?

Any chance of getting pictures?

[555BCTurbo]

Yes, it has 5/16 barbs and a 1/8th vacuum barb.

It is for sure a rising rate, as I watched the gauge when I revved it, and it raises pressure greatly as it progresses towards boost.

I did not buy it new, so I don't know the actual ratio, but from what I gather, most Weapon R regulators are 12:1.

It is base pressure adjustable as well as rising rate.

If you have anymore questions reply or PM me

Thanks for your patience answering my questions.

You tested it by revving with the car stationary? So manifold pressure stayed below atmospheric, right? So this RRFPR acts at all times, not just on boost? How did that affect driveability at cruise and low loads?

[555BCTurbo]

Ok...first thing, the RRFPR is sold.

I will still answer your questions Vikash


Yes, I was stationary, so I did not hit boost while revving, but it did still react. While driving, due to the high rise rate, it would dog out the car a bit at the lower RPMs, but once on boost it would pull like a mofo. I think that if someone were to bleed off some of the reference vacuum/pressure it would be much better suited to our application.

[vrg3]

Hm. Cool. Well I hope it works well for whoever bought it . I think I'd prefer one that only acts on boost anyhow.

Thanks, Nick.

Wait, I thought Vikash kinda had dibs here. I probably would have bought it(if my car was fixed) but I didn't want to steal the deal from V. I'm not bitching for myself, or for V(he's a big boy ), but I'm just not too happy with how this went down. Just expressing my concerns.

[vrg3]

Well, in fairness, I only said I was interested, and I think my questions did make it fairly clear that I wasn't sure.

In any case, it's always the seller's prerogative to sell to the first person who pays. I've been on the other end enough times to understand how frustrating it can be to wait for someone who's called dibs to pay up, and how much more frustrating it is when they back out, as they do occasionally.

I appreciate you setting this straight Vikash...



Binford- I knew that Vikash was not really interested in it, and when I recieved a PM saying that the individual wanted the part, I sold it to them.

[Binford]

Well, no harm done I guess.
