Get back in the game

 

if i keep the cobalt for the remainder of this year for sure i will.

 

Well guys went yesterday to get tuned for boost well turns out Hahn sent the wg with the 7psi spring WOW so disappointed. Lol so now what should I do guys go with another 7psi spring or 10psi spring to stack with the current one?

 

You don't have a boost controller?

 

Yeah can I just use that????

 

yes. the spring in the wastegate. unless you only want that amount of boost. is just a "baseline" so to speak. your boost will never be below spring pressure. with a boost controller you can somewhat over ride in basic terms that spring pressure. but it's not like you can run as high of boost as you want. the spring will determine how high you can go.

click link. hover curser over "turbo tech". it'll give you just about every piece of info you need.

 

I mean that is what I figured, but thanks

 

Ok could i say run twice as much boost? Just trying to get an idea. Checked out that link it will be added to my favorites thanks

 

you can usually double the wastegate spring with a boost controller so if you have a 7lb spring should be able to run up to 14psi with boost controller

 

Awesome I will give it a try

 

Hey guys. My fuel pump has been makin a funky sound during priming lately. Its a walbro 255. Been in the car for a few years. Less then a yr on e85. Car has been acting up lately as in stuttering like fuel starved and during warm up stutters and gets a bad idle dor short peeiords and sometimes dies. Think I may need a new pump? Any suggestions? Ive replace my fuel filter already. Also has been running leaner according to my wideband when I get on it hard and it breaks up bad.

 

Sounds like the walbro is on its last leg. Get a deatschwerks. No more problems.

 

Is it a direct swap? I have a return style setup.

 

Almost. A little trimming with a dremel (like a couple minutes worth) and it drops right in.

 

ill have my aeromotive steath 340 pump up for sale soon. i needed more fuel so i bought the walbro 400lph fuel pump.

 

Hows it handle e85? I daily my car and I heard that pump likes to over heats and fails. Hows ur experience been with it?

 

The stealth does not like corn. Some last a week some last a month, a handful last 6 months plus.

 

Ok thx!! Hows the swap from a 255 walbro with a return setup too the dw300? Direct swap? Any lines different?

 

The lines all stay the same, you're only changing what's in the tank.
I've never I stalled a walbro, so I'm not sure. But for installing the dw300, all you have to is take a dremel or even a file and open up the hole in the canister that the power plug clips into, then take about 1/8" off the sending hose piece so that it can clip onto the pump.
The plug opening is obvious once you look at it but here's b/a pics of the other part.

 

Ok. Great. Should be simple then. How long have you been using the pump for?

 

Roughly 50k

 

How can I tell if my pump is for sure going bad besides the symptoms im experiencing now. I havent noticed a fp drop at my regulator. Damn thermostat is stuck open. Replacing that and my wideband sensor tuesday. What should I look for in my short term and long term fuel trims. How can I tell if its leaning out by the numbers?

 

Also believe I have a bad battery. Could that cause any misfire/ stuttering issues if I have bad cells in the battery?

 

Does anyone here have an LSJ throttle body harness? Or does anyone know where I can get one?

 

check ZZP, not sure if you need an extension or not
