Alright guys, well I've pretty much pieced together my entire supercharger setup and I'm just waiting on some small things but while I'm waiting I'm thinking about the fuel setup. I have a set of Siemens 60lb injectors (I know they are big lol) and I have a new SVT Focus Fuel Pump laying around.

Now I have been contemplating just picking up a BAP and running that with the SVTF pump but I've been searching around and I noticed a few guys recommending this DivisionX Stryker Fuel Pump. Unfortunately, I know it's a bit new so not a lot of guys are running it but it looks to be exactly the same dimensions as the Walbro GSS342, so I'm assuming it'll drop right in and all I'll need is to trim the basket a little and drill two holes at the the bottom of the basket to run it.

For reference:

(flow numbers definitely look nice)

So I'm open to opinions and I'm looking for more information:

Should I just run my SVT Focus Pump, buy a BAP and call it a day?

or

Should I just buy a new DivisionX Stryker Pump and run that?

Also, anybody who has installed one of these Stryker Pumps, please shed some light on the install (ease/difficulties), and anything special that needs to be done to get it to fit?

(I figured I'd make this thread since the SVT Focus pump is a very popular option and I don't see any threads about the DivisionX pump so if this proves to be a great way to go then it'll help others out in the future as well)

Thanks guys!

[MT0911]

Any guys running the DivisionX Pump?

[86er]

never heard of it here, but I dont see why the install would be any thing different from the 255. Im sure there might be a smidge difference, but nothing that couldnt be handled during the install.

Id run the single pump with out the bap, I like stuff simple and the fewer things you have to wire in, the better for me.

[Shaun03GT]

Agreed with 86er. A single pump is better then a pump with a BAP...just another chance of something failing.

I say run the 340 pump. Talk to stal about it, I think he has some knowledge about it.

[MT0911]

Yep Stal is the one that I heard about it from and I sent him a PM about it and gave him the link to this thread. I don't think this pump has ever "officially" been reviewed or covered on MM and I thought "instead of finding out for myself, why don't I just create a thread so everyone is aware of this option".

86er - I actually think the Walbro and the Stryker are literally the same dimensions completely, so nothing would really be different for the install but at the same time, since I've never installed one - I am not for sure. I just figured I'd ask in case we might of had some guys running it that could jump in and talk about it.

Or.... maybe I'll just pick one up and be the guinea pig . It actually seems like a good pump so who knows, I'll probably end up just buying one and running it and if all goes good, I'll write up my own review but if not, I'll have the SVTF pump on the sideline just in case .

Hopefully Stal gets in here and can provide some knowledge.

Im sure its a pretty easy install. For the Ford GT pump, I soldered on spade terminals on the prongs, and soldered the wiring onto them. Took the basket, I wish I took pictures, but drilled a couple holes in it. 2 in the bottom and like 3-4 in the front so the pump wouldnt suck the basket dry.

Honestly, best thing you can do (besides going return style) Is buy a cobra hat with pumps. That alone will support about 450rwhp...throw a BAP in the mix, itll support close to 600rwhp.

But for that big single pump, Im really curious to see about how much power one of those pumps can handle.

I say definatley go for it.

Since your the guinea pig do me a favor and try the whole wastegate theory too lol

[MT0911]

To be honest, I'm really just looking for around 400 whp - little more, little less I'll be happy. Right now while I'm making in this range of power I don't need my fuel setup to be very extensive. I predict that it will be a long time (3+years) before I even attempt to drop in a forged block and supporting mods to up the boost and put down some big numbers. But when that time comes, I will thoroughly setup my fuel system the right way. I am leaning towards getting this pump (90% chance = which pretty much means I am going to get it lol) and I am also curious how it will perform. I guess when you see my little build thread and dyno day comes, we'll both see lol.

As for the wastegate theory.... maybe another day

[Shaun03GT]

LOL figured Id ask.

Well, you have a nice setup. I believe you went HPX Slot style MAF which was a smart choice, 60lb injectors gives you plenty of headroom (600+rwhp) and the fuel pump...who knows. Could suck, could be great. So many fuel pumps are hit or miss. Just for example, 0949er is at 435rwhp on a single 255lph fuel pump. I maxed my Ford GT (310lph) pump at 375rwhp. So didnt a couple others. But Ive read people getting 420+ out of them without a BAP. And Ive seen 255lph pumps max at 360rwhp.....lol so Idk, its fucking weird.

Only reason why I bought the Ford GT pump was so I didnt need a BAP and to I guess, save a couple bucks. In the end though, hurt me. $150 for a BAP, and another $100 for a re-tune.

If I was doing it over again, Id do it exactly how your doing it. 4 core intercooler, HPX slot style MAF, fuel pump would either be that or a Cobra hat w/ pumps.

Your being smart. I think youll make some great power with the Si and about 10psi.

[stal94gt]

I answered the pm about this but a fyi the division pump is not a hard install but does need the lip on the bottom of the fuel basket lid needs to be trimmed to fit

[Matt86]

Aeromotive Stealth 340 pump

Im not sure if he ever installed his, he may be of some help to you.

I bought 2 division x stryker pumpsm and their billet hat. So I know the install will go just fine but as for the pumps lethal says one is good for 500 NA hp. so 400ish boosted hp..

should have waited for justin to release the new fore setup and went with the new 405 pumps

Yea, that's the thing, I hear about so many people hitting different numbers with the same pump I don't know what to believe lol. I know some guys max out the SVTF pump at 350WHP and some guys get up to early to mid -400's. I completely agree when you say it is hit or miss.

I'm hoping I make some decent power, I wasn't on a complete budget trying to put together this kit but I was definitely trying to save some money. Buying that complete V3 Si-Trim kit for..... 1800 shipped was probably the most awesome deal I got lol. So a big thanks goes out to oonegtstang for hooking me up with it. But I think in total I made it out spending less than 3k on everything and I believe I put together a pretty solid kit. Everything looks good except the question with the fuel setup. 60's, SVTF pump, BAP = not the greatest setup but will support it just fine. 60's + DivisionX pump = on the edge still (I don't want to buy it and then end up needing a BAP anyway; if that's the case then I will feel very similar to you when you got your Ford GT pump lol)

But I'll have to see, and as I told Stal - I'm still in the decision making process which path I want to go.

Thanks Stal, I got your PM and replied to you. I appreciate the insight.

Hmmm.... so only around 400ish boosted? You see, that is something that was on my mind. Since not many guys have ran this pump I actually haven't heard any numbers besides what you just put down; I could only speculate. I know an SVT pump and BAP could easily support early to mid 400's so I think I would be pretty bummed out buying a DivisionX pump and hitting damn near 100% duty cycle on the dyno. But nonetheless that's good info man. How do you like your setup right now? I think you are one of the only guys on here that I've seen run them.

[NC85]

Someone did a write-up on modular fords I believe. Search aeromotive 340 and it should pop up.

I havent ran them yet, I will need a tune and am waiting until after my new engine is complete. Lethal said they are good for 500 N/A hp without a bap. The stryker flows 340lph at 13v IIRC. It takes about 7% more fuel for every 5psi of boost give or take. so at 10lbs of boost the stryker 340 pump alone should support 430hp. This math is all theoretical as all setups are different.

I look forward to hearing your results man. It should be nice since you're running the dual setup. I'm getting ready to purchase one and just run that alone and see how it does during the tuning process. I should be completely fine.

yeah and the nice thing is i can go retuen by just running a return line to the hat and get a tune. Hell i may jsut go return and be done.
