Wally 190lph questions.

[gusu]

So I'm looking to upgrade to a Wally 190 pump because it will be cheap and quick plus I don't want to buy a pricey FPR.

I can't seem to find any information on how much this pump will typically make before it will start to cut out. I found out that the 255 typically makes around 550 before it starts having issues with flow.

I am looking to do a build like this.

Cometic head gasket
ARP headstuds
FP manifold
Evo 3 B16g
272 cams
revised lifters
ECM-link V3
Not sure on injector size just yet. Maybe 750s?

Anyway, I'm wanting to make 320ish AWHP (dynojet) on 93 octane as it is the best we can get here. I was wondering if the 190 can do that? I'm not exactly sure how the scaling of the 190lph vs the 255lph works, so would I be safe to assume that I'd be able to make that kind of power on this pump?


*edit* Oh, I forgot to ask. I was also wondering what boost level can you typically make on a 14b with a rewired 190 on stock injectors? I'm not looking to do anything insane but I heard 18 PSI is possible, any truth to that?

Get your self a evo 8 or 9 FP and save some money. A evo 9 rewired flows around 210 if i remember correctly and is more then enough for your e16g. You can normally get them for around 20-40 bucks and it does not whine. Also skip on that cometic HG.

Walboro 190lph (Rewired)

10psi = 60.68lbs/min
11psi = 59.85lbs/min
12psi = 59.01lbs/min
13psi = 58.16lbs/min

22psi = 49.71lbs/min
23psi = 48.68lbs/min
24psi = 47.64lbs/min
25psi = 46.58lbs/min


450cc @ 100% IDC will support 32.30lbs/min
450cc @ 80% IDC will support 25.84lbs/min

Some evo 560's would meet your goal and they're cheap. Running 100%idc is risky. A spike could cause you to run lean, it will also wear prematurely. The 190 is plenty and wont need a aftermarket fpr.

IMHO, there's a fine line between using a rewired stock pump, evo pump, or the 190 at the power levels you are talking about. I would personally either go with the 255hp and an AFPR and be done with it, or just rewire the stock pump or maybe drop in a rewired Evo pump if you find one cheap.

As for the injectors, might as well go big since you will be running ECMLink. Anything between 650 and 900cc's is in that gray area kind of like the pumps, where they are useful for a narrow power range and not that big of a cost savings in the long run.

It all depends on his overall goals. IDC on the injectors would not be high on pump gas.

Why buy a 600hp fuel system for a 300hp 16g? Your talking about 1k in parts. When all he needs is a 190 and evo injectors, which should cost him under $200.

Why buy a 600hp fuel system for a 300hp 16g? Your talking about 1k in parts. When all he needs is a 190 and evo injectors, which should cost him under $200.

Because:

1. There isn't a huge difference in price between them these days, and

2. I've never met a single DSM'er (myself included) who has been content with their initial power goals, and didn't end up spending more in the long run instead of just planning ahead.

I wasn't saying to go big or nothing. I just don't see the point of a 190 pump with that narrow range of power; and larger injectors aren't all that much more than the mid sized ones.

...or just rewire the stock pump or maybe drop in a rewired Evo pump if you find one cheap.

 

[91stocker]

Yea thats true i guess. No one likes dropping the tank more then once either.

But the reason i asked about your recommendations were because hes wanting to push his 14b, then..upgrade to a 16g. Just sounds to me like hes a few summers away from using more then evo's and a 190.

evo injectors+190 - $200

afpr
mid size injectors
255 - $550

Not all bad either way i guess.

Depends, you can get the AFPR+255+mid sized injectors around 250-350 if you shop smart. You don't need them new. Besides, it's always better to have an easy-to-grow fuel system. Pushing it mid way is better than pushing another pump to its maximum. As said before, it also leaves opportunity for upgrade since in most cases the fuel system is the bottle neck. I had a 190 before, just bought a 255 two days ago

Yea but hardly anyone will EVER make 600hp. Its really just a bit of unnecessary cost. Specially for someone on a budget. Most people also will not flow 43lbs/min on a 16g so again the 190 is fine.

Also as i said before, hes planning on pushing the 14b then upgrading to a 16g. So this 600hp turbo build will be a few years out im sure. The cost of the afpr and larger injectors will add a minimum of $300 to his cost. To some people 300 might be alot of money. Thats about what the 16g goes for. I just dont see a reason for the extra cost and work in a eventual 16g street car.

Unless the op is going to upgrade to the 16g then again to a larger turbo in the near future.

Its like these guys with 3k trans running 13's. Or a couple grand in mods and running 13's-14's. When high 12's is possible on close to stock fuel system and stock turbo.

 

[4Lurker4]

I totally agree with you, I was just saying he can get cheaper than 550$ for that kind of set up, specially if he's looking into used parts. As for the rest, was my personal opinion, I just rather get a system capable of doing more (where it usually ends up being the determining factor on upgrade) and run it in it's mid range potential so I'm sure I'm not pushing anything to breaking point (I do everything with a huge safety margin)

 

[gusu]

Thanks for all the information guys. I think I'm going to stick with the 190 just because it's less trouble then having to worry about a FPR having issues and having to learn how to adjust one for now.

I'm not saying the 255 isn't good advice, honestly I was really considering it but I don't think I'll need that flow rate for at least a few years. I don't want to buy something I may never use when it could possibly cause fuel pressure problems.

But I do think since the cost is the same I'll go a bit larger with my injectors, it could help with my potential build or I could sell them to a friend for one of theirs when I'm done with them.

 

[Imback]

some of you people are to much on this board. evo FP and injectors will be under 180 and be more then what you need.

Whats the evo fp flow? Ive personally never seen one for sale. Never checked the evo boards either.

Edit: Scratch that, seen flow rates in your first post.

 

[4pistons]

I have a setup very similar to yours, minus the 272's, and I am probably close to 320awhp.

I dyno'd at 275 awhp with my old 14B at 18 psi and a Starion IC. That's about 320 engine.

With the B16G and new intercooler I know it's close to 320awhp. One of these days I'll get it back to AMS for a current dyno.

I used to run as high as 23 psi on the 14B but it would fall off to around 19-20. I run a steady 23 - 24 now with the B16G still on the 190 Wally.

Funny thing is that you don't really need a AFPR if you install a 255 pump

 

[1990AWD]

I took Calan's advice and went as big as I could afford and I will have just the 14B for a few months. Wally 255HP, 1000cc injectors, and an AFPR cost me $575 and that was with everything new and shipping to Canada. This way I never have to worry about my fuel system until I max out an FP Green or something.

 

[dsmluver98]

Was jus wandering if I could ask a few questions since we are on the wally 190 info. I have a 93 Gsx and I had to upgrade because my old one jus shut out. Now I installed it. And the car takes a lot to crank over before she fires up and then while idling warm a/f is bout 16-17.7 now once I'm driving a while and sometimes a short time. While in full boost. Which is only 9 psi the a/f is 15-16.8 and sometimes spikes to 18 but once I notice it and let off the gas it jumps to 10 flat. Before the old pump went a/f was great and I was gonna crank it to 15 psi but now this is going on. And I also here almost vibration sometimes coming from inside the car. Any ideas
