Re: my new project
 

The Ford gt pumps? My car would creep to 35psi and I want to see 40+ when I get it figured out. Shane said to get a couple 255s and pop the relief valves

Re: my new project
 

Or if I'm feeling rich maybe I'll go twin 450s haha

Re: my new project
 

;)


Boost looks like its coming on pretty decent.

Re: my new project
 

Did Shane test your fuel? Interested on results and the last place you filled up?

I know that isn't your issue at all just interested if he did.

Re: my new project
 

Don't forget the BAP! lol

Re: my new project
 

I have no fuel issues with twin 255s.

Re: my new project
 

For a journal bearing 6766 with a big a/r I thought so too

I'm not sure if Shane tested it or not. I filled up at the holiday in flake last. I have a couple jugs full that I have got yesterday and I bought an e85 tester so I can test it.

Lol idk if we need one yet lol

How much power are you making?

Re: my new project
 

High 600s at 39ish psi. My injectors are maxed so I can't do much more without changing them up. But I'm happy with mid 600s at 33 34 psi. It makes for a fun street car.

Re: my new project
 

^That's dynojet isn't it?

Re: my new project
 

I was running 38psi, they would eat face pretty good just getting to 32psi.

Re: my new project
 

Pretty good numbers. What kind of dyno?

Were you using ford gt pumps or walbro 255s?

Re: my new project
 

Yeah, dynojet. On a 2.0l, Jb 6262, -6 feed on e79, bm1450s. Nothing crazy.

Re: my new project
 

Still pretty good numbers! I'd like to see over 800whp on a dynojet

Re: my new project
 

Bummer you ran into issues, but a dyno is just a tool and it helped you discover an issue which is still progress. I have no doubt you'll get it figured out and be back on there for round 2 soon.

Re: my new project
 

Indeed that's why I'm not too upset. We got some issues fixed and found that there were multiple causes. It is what it is. Based on the graphs I got I would say things look pretty promising

Re: my new project
 

That was on the ford gt pump, i switched out for a 255 and no more issues. I have a dw300 I could sell you.

Re: my new project
 

Okay cool. So these pumps are definitely coming out asap then. I might look into getting a rebuild kit for my regulator too just to be on the safe side

Re: my new project
 

Twin 255hp's with relief mod. Proven since the early ages, and cheap. Hard to beat that.

Re: my new project
 

Meh, don't waste the coin, just do a pull and see what it does. (regulator)

This, but you will run out of fuel Vassil did with smaller turbo on the same dyno.
Granted 2.4 instead of 2.0, but you have the bigger turbo too.
I'd say twin 300s if you can get them for a deal.

Re: my new project
 

Depends on if he has other restrictions in his fuel system too though.

You need to have upgraded lines, rail, AFPR etc and get rid of all restrictions that cause excessive fuel pressure. If you can keep the fuel pressure as low as possible the pumps will flow quite a bit more.

I am not saying one way or the other, you might be right that he needs bigger pumps, but i just don't know either setup enough.

I personally wouldn't run dw300's in anything, they haven't shown to do dick over a relief modded wally 255. I'd run twin 450's if you need that much fuel, or man up and do a full setup using a big ass weldon.

Re: my new project
 

I got some E85 in Rogers yesterday and it tested out at 84.92%


Bummer it didn't work out for you but if it's a matter $200 or less for 2 walbros that's an easy fix!

Re: my new project
 

Twin weldons, -14 fuel line, 1" fuel rail, and some Moran 4500cc injectors should do the trick. :D

Re: my new project
 

Everything I've heard the 300lph pumps don't hardly flow more than a 255. Big ass weldon just isn't an option right now lol. I'm pretty sure it's a stock rail but I know the 1g rails are good for a ton of power. As for lines I have 1/2in fuel lines but I'm not sure what the return lines are. Shane seemed to think a couple modified 255 should be capable of over 800 on his dyno so I should be good to hit my goal with those. If not we'll add a bap or go to the 450s. First and foremost I need fix the issue and verify it's fixed.

Yeah it wasn't a complete failure. We now know that a lot of the issues from last year are fixed. I'm going to try some new pumps and go from there. Hopefully I'll be back up there soon!

Haha are you paying for that stuff for me? ;-). I already have upgraded lines, pretty big injectors, not sure on the fuel rail though think it's a stocker with an fittings welded to it. Well try different pumps and go from there

Re: my new project
 

Add a BAP at that point, that's my thoughts at least.

Re: my new project
 

FTFY ;)

Re: my new project
 

To me having to do dual fuel pumps and a BAP seems like too much crap.

I like BAP's for single pumps, but if you are doing a twin setup, just do two bigger ones I'd think.

I dunno, just seems like less nonsense with putting the right size in there.

Re: my new project
 

I was just leaving to head to map to get some pumps and got a text from josh (bramagedained) that he found his pumps that were already modified. He gave me a deal I couldn't pass up. So i got a couple 255s. Now I just need to get up to db to get my car.

As for the bap vs going to bigger pumps it's a little bit of a toss up for me. 1g dsms have such a shitty charging system I think I would lean more towards a bap to keep a solid voltage at the pumps but idk

Re: my new project
 

I picked up a couple 255s with the relief valve mod. Then when I picked up my car from db I got some submersible fuel line. I put the fuel pumps in and replaced the rubber lines in the tank. I did find a hole in one of the rubber lines I replaced. I did a couple 3rd gear pulls on the highway and the fuel psi just seemed to keep climbing so I think we're good to go. I'm going to talk to Shane and see what he thinks.


I also want to try and wire my wideband into the aem so I can log afrs and I want to get a fuel pressure gauge that has a 5v reference so I can log fuel pressure.

Re: my new project
 

Nice! Rock on dude!

Re: my new project
 

Thanks!

Also I was talking to swift and he said that the wideband is already wired into the aem. So my buddy is putting together a new laptop for me so when I get that I can double check that. So now I just need to look into a new fuel pressure gauge so I can log fuel psi.

Re: my new project
 

Sweeeeet

Re: my new project
 

Nice dude! I'm glad it wasn't something more serious.

Re: my new project
 

When you hitting the dyno again? Looking at the dyno graph looks like you should hit 700hp. What does your car rev out to?

Re: my new project
 

Glad it was an easy fix and that it takes care of the problem.

Time to go make horsepowa!

Re: my new project
 

Thats good that you found the problem!

Re: my new project
 

Thanks guys! I really hope that was the issue. Guess we'll find out when it hits the dyno again


Not sure when I'm hitting the dyno again. I have to talk to Shane and see when he can fit me in. 700+ is still the goal for now. I'll probably rev it to 10k

Re: my new project
 

Holy nuts 10k. You have race car. Hope you get back on the dyno soon. It would be awesome if you could go to the half mile races in chicago.

Re: my new project
 

Lol. Or at least 9500. It's built for it so why not, right? Yeah the half mile race in Chicago would be fun! Unfortunately it won't be in the budget for this summer. Plus idk how well my car would do with the tranny I have in it. Probably would need a dogbox for half mile lol

Re: my new project
 

Any plans for E98? 40psi on E70 with next to useless knock detection/control isn't the best way to go.

Re: my new project
 

We'll I would really love to see 40psi but that was something I was going to talk to you about once the fuel issues are fixed and we can actually tune this thing. I would like to do e98 but idk if it will be feasible for me to do this summer. Also I would like to switch to link and get rid of the aem.

So when it boils down to it when we actually tune it if you don't think it's a good idea to push it that far on pump e85 then we won't.
