Engine/Transmission (1998.5 - 2002) Are my new mods suppose to be this loud??

[PC12Driver]

The -6 or -8 that rivercat mentioned is the line size, not the pump model. Did any of the banjo's get replaced or did you just ad the pump?

 

[RacinDuallie]

NOt sure which pusher it is... a Carter is about all I know. As for the barking, having heard it in awhile. I'm still playing with it, I'l get some better numbers through the day and week. Once I know exactly what my EGT's are on 5x5, I may consider the 12cm housing... depends how much room I have to play with regarding the EGT's.

I'd reconsider that thought on changing the housings around... ..... What if you want the next step up in injectors? ( which B. T. W. will help light that turbo more )

Keep a strong eye on that Carter... ... How come you didn't go for a FASS anyhow? Should make it one of your future mods later on down the road-you can either use the supplied hose and fittings or go bigger ( it's a little more work to do but not too bad)

All in all I'm glad everything worked out well for you and am glad to help you through with this BOMB... ... .....

Kudos on the gasket- sillycone is just that silly! Get yourself another gasket... .

 

[Clmsnow]

Got to be honest with you guys... . what is a banjo? I didn't change any fittings other then the two that were supplied with the pump for the in/outlets. As for the FASS, I have hard great things about it... when I ordere my turbo and AFE I told them I needed a pusher pump of some sort and that is what I got. I kind of wanted to limit my spending(I had put on the Comp, FP gauge and transmission updates 2 weeks prior). I would like to see the thing spool up quicker, with the 12cm, but I may want bigger injectors so I'll drive it for awhile first. I'll get the gasket today.

 

[RacinDuallie]

Oh- that explains it- The Bomb Bug is alive and well in Cali. and it got a nibble on you... ... ... :-laf :-laf :-laf ...

Banjo bolts are the funky fittings that are used in the stock fuel system if you look at your lift pump and look at the line connections where they connect to the filter housing and the VP44 that'll be banjos... .

Banjo bolts are the funky fittings that are used in the stock fuel system if you look at your lift pump and look at the line connections where they connect to the filter housing and the VP44 that'll be banjos... .

... and they have tiny passageways for the fuel to flow through. Right now that's your biggest restriction to flow. Replacing the banjos with higher flowing versions (like the one's from Geno's - you can also see what they look like on their site) would be the low cost approach, replacing the lines with a setup that doesn't use banjos at all would be the best flowing setup. Like I said above, just replacing my lines gave me 16psi @ idle and 10psi with the box on kill (460hp), and that's with a single factory pump. With your pusher pump and upgraded lines, you'd have enough fuel to run two trucks.



Yes, the larger injectors will spool your turbo faster... . at full throttle. At anything less (i. e. daily driving) there will be no difference in lag. Extra fuel makes things spool faster; if you're not using the extra fuel you don't get quicker spoolup.



Keep in mind that HTT will swap your housing for a different size for $150. For that price there's no reason to have to deal with lag.

 

[Clmsnow]

That seems like an easy fix with the lines. I'll get on their website and take a look.

 

[Clmsnow]

Made a good run again, from about 10mph up to 85mph. On 5x5, hit 1261* EGT, 35. 9 psi boost and fuel pressure was steady at 9. Before shifting into OD, the FP dropped down to about 6-7 for a split second, but runs steady just below 10. Lag isn't that bad, just need to stand on it. When I put the pedal down the lag really isn't too bad, it is when I am in town and taking it easy that it takes longer to spool. Pretty darn fast

 

[RacinDuallie]

Which is why I was saying to reconsider the housing change..... If you can live with it for now and later on when funds allow upgrade to better injectors and a real pump. 5 x 5=1260* not bad, not bad at all... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ..... Oo.

 

[Clmsnow]

Ran again... . 1281* and 35. 9. All on the freeway, nothing up a hill yet. Pretty hapy with it. What would a FASS do better to what I already have? How much bigger injector could I go with and be safe with my current set-up? Maybe Mach-2's??

Clmsnow- Gonna say this again- everything that your lifelines is telling you seems to be pretty good!! But- I really don't like hearing the fuel pressure drop down to 6-7 psi... Don't get me wrong its still in the 'SAFE' area, but it's that drop... ... .....

You've seen the raves the other members report with their FASS systems, I have the FASS and it's staying on my truck, and that's that!! Your pressures would be more to the top side of the scale as apposed to your set-up that is towards the bottom of the 'safe' scale... .

My advise, if I was in your position- and don't get me wrong I know what it's like- atleast you addressed the fuel issue within the means that you had at the time- but- before you even think about changing the injectors, I would first tackle upgrading the fuel pumping issues with a FASS System- with the filters/pump.

Again your current set-up is working o. k. - but that's it-o. k. Plan a FASS in there in the future and you'll never have to worry about fuel pressures again... . Service the filters are a breeze. And the pressure... ... ... oooooohhhhhh the pressure. You'll see what I mean..... Go out and enjoy your new set-up for now- and by the sounds of it it sounds good... but make a mental note for later on when you feel a burning sensation in your wallet... ... ... ... .

RD, have you considered maybe giving the pros and cons of every mod you suggest? (since every mod has a negative or an alternative) Or maybe asking someone how they intend to use their vehicle? Keeping these things in mind will add value to your advice. Not everyone here is in to 1/4 mile times and how the truck behaves @ full throttle. Some of us are into extra power with drivability and reliability.



A good current thread about how everyone "raves" about the FASS can be found here.



Clmsnow just spent $$$ on a fuel delivery system that will work just fine with a little help. Of course it has tremendous pressure loss while flowing because he still has the factory tiny banjo fittings. With banjo upgrades alone he'll have great fuel pressure for what he's doing now. A complete line kit is about $150, and with that and his pusher he'll see enough fuel to support 500+hp. How much more would he gain by scrapping what he has and spending $500+ on a FASS?



The FASS setup does give good solid fuel pressures and the filters are really easy to change (not that a 2001 is hard). But I didn't get one for several reasons. First, because I don't need it (10psi minimum WFO with the factory pump and upgraded lines and fittings). Second, I'd loose the Convenience of readily available parts on the road (I can get filters and pumps at any Dodge, big rig, or farm tractor dealer, and some marinas). Also, I didn't want to loose my factory fuel heater (instant-on electric vs. the engine coolant version on the fass) or water-in-fuel sensor. And then, of course, there's the price.



If I do need to upgrade, I'm gonna get the RASP (engine driven pump with the factory electric as a backup, and fully regulated). I won't loose any of my factory system and features that I like and I'll have redundant pumps as a fail-safe. It is a high cost setup, but it's well thought out.



Clmsnow, back to your truck. Like RD said, 6-7psi isn't dangerous, but it could be better with a little help (banjos). And with upgraded lines you'll never need another system.

I have only seen 6-7 once. Last night I made an "exhibition" run for a friend At WOT PF was at 9. That seems to be where it stays when I am on 5x5 at WOT for long periods. The only time I have seen it lower is it between gears as it is running out before it shifts. I'll look into the banjos and lines. I have heard alot about the FASS and RASP, I'll look into those in the future. As for larger injectors... . sure, maybe someday, but for now I am pretty happy with it. What injectors would be best for me in the future?? Thanks again guys for all the help and great suggestions.

The bigger banjos helped me out some. But, it did not raise pressure any huge amount. If I had to do it again, I would skip the banjos and eliminate them all together. It's compatible with whatever fuel system that you may add in the future and you will see an instant improvment.

I didn't see anything on Genos website about the banjo fittings or replacements. I called and the guy said they didn't carry anything like that. Where did I go wrong here?

 

[RacinDuallie]

Clmsnow,
Tell them you need part # BF-Kit 4/1 comes with 4 Banjo bolts, 1 tapped Banjo bolt and 10 Cummins gaskets... ... . This is the recommended kit for 2000 and up Dodge.

They are made by TDR member Ray Torresdal out of 12L14 steel and feature . 187" vs . 130" fuel ports price is about $40. 00.

Last year, I talked with Geno's about the larger banjo's they didn't recommend them for increased pressure. I ended up buying a fuel system from Scotty. It uses 8 an fittings from the lift pump forward & 6 na from the lift pump back. Replacing just the filter to VP line didn't do any thing noticeable for me, but when I replaced the lift pump to filter line, my WOT pressure went up by 5 psi. That is still with the stock banjo & line from the lift pump back. All that is to say that larger lines with high flow an fittings help a lot in delivery of fuel under load.

 

[PC12Driver]

Here's the Geno's link:

http://198.104.149.53/CoastalData/showdetl.cfm?&DID=30&Product_ID=593&CATID=1

You may or may not need one with a tapped fitting depending on where your fuel pressure sender is located.



That Scotty kit is the one that I have (got it back when Wildcat was selling it). His info is here:

http://www.scottyairsystems.com/



Power by Poole also has a similar kit here (its 6an instead of 8an though). Also a good shot of the RASP on that page.

 

[RacinDuallie]

With these Banjos, I don't think it's a pressure improvement, I believe it's more of a volume delivery improvement... ... ... ... ... ... ... ...

 

[Clmsnow]

Is it a problem that I didn't put a fuel filter before the pusher pump? Also, what about the next stage of injectors??... when the time is right.
