Seriously... lol


Aaaannndddd.... It looks like I've got a new shopping list. Fixing my exhaust this time...

The reason why I say that is because the v-band flange used to make my exhaust doesn't match up that well with the flange on my turbo, the result is that I have a bit of an exhaust leak where the turbo meets the downpipe.

We'll remedy that leak and fix the lack of flex couplers in my DP/WG pipe all at once. I'll also switch from the crappy slip-joint that PFS used to connect my DP to my MP, replacing that with another v-band connection.

Shopping list being:

1x Vibrant Flexible Exhaust Couplings (4"x8") w/ Interlock Liner - $100.55
1x Vibrant Flexible Exhaust Couplings (1.75"x4") w/ Interlock Liner - $24.90
1x Vibrant V-Band Flange/Clamp Assembly - Stainless Steel Flanges (4") - $91.30
1x Precision Turbo and Engine V-Band Turbine Discharge Flange for PTE V-Band inlet/outlet Turbine Housings - $49.99
1x Precision V-Band Clamp - 3.00" - $24.99

We'll need to wait until I get a bit more funding before addressing these little toys.. Brian, please let me know if I'm missing something

Aside from none of the links working

One of these in a 1.75"

get a foot of this

One of these - discharge obviously
http://www.verociousmotorsports.com/...langes-304L-SS
and one of these - discharge again

and money.... lots of money for ME!!

Tha fuck... that's strange... the first two pasted in wrong... ah-well, got them sorted.


So we're completely redoing the WG (re)routing? cool beans, I thought we'd just be adding a flex coupler to what Ray did. Works for me though, as I'm sure it's gunna be much better than the hal-assed job the last guy made..


It fucking kills me... I paid WAY too much to get the exhaust made, only to have him cut corners so now I've got to go back and get most of it redone

[TitaniumTT]

Pie cuts and cheating radii is not an acceptable way to build an exhaust.

[Fendamonky]

One of these days I'm gunna learn to weld... It'd be so nice if I could do/fix this shit at home...

[Fendamonky]

So the new(to me) fuel pump came in last night. I just swapped it in this afternoon. It took me about an hour start to finish, to include some time spent messing around. It was surprisingly straight forward. I made sure that the pump was completely full of fuel before re-installing it, so I shouldn't have issues with this one (hopefully).

I'll have to flow test it later as I don't currently have a -6 male/male connector.

Your going to flow test it before it's fully tuned right? I hope? That's a lot of money in that build to chance it to a used pump. My 2 cents anyways (coming from a person who has blown a couple engines because of a pump and wiring)

Absolutely gunna flow test it first! I just need to get the -6 male/male connector than I'll be in business.

Done and done =) I neglected to take some "after" pictures because I was too intent on going straight to flow testing the fuel pump, then taking the car for a drive to make sure everything was good =)

I put the new length of 5/16" fuel hose in (I got rid of the 6" double loop and just went with a straight shot from the fuel pump to the feed line) then fired the pump up and checked for leaks. Tightened up the clamps a bit more after spotting a leak and proceeded with the 43.5psi flow test. I was kinda worried that when I cranked the FPR up to 70psi (it wouldn't push higher than 70psi by the adjuster on top of the FPR) but the fuel line held fine and was leak free =)

As for the fuel flow...

At 43.5psi it took 5:42.5 to fill 5 gallons.
at 70psi it took 6:31.5 to fill the 5 gallons.

And my handy-dandy garage note pad..



Please correct me if I'm wrong, but to find the GPH would I divide the time by 5, then multiply by 60? It's been over a decade since I needed to use math for daily questions/problems (I would ask Bianca, but she's worse than Chris at Math..)

Not possible. Bianca can actually count her fingers AND toes.

[Fendamonky]

So I spent about an hour manually searching through the Lounge here to find a thread Brian made forever and a day ago about GPH calculations. Why did it take me an hour to find a specific thread made by Brian???? BECAUSE THE FCUKING SEARCH FUNCTION FAILS!!! lol

Anyway, posting this link up because pertinent.

So, from the thread above I found this:

18.95 Liters pumped in 233 seconds

.081 Liters per second

.081 LPS times 60 seconds is 4.88 Liters Per min

4.88 LPM times 60 minutes is 292.79 Liters per hour.

292.79 LPH.

My guess a bosch O44.

As per Bryans post I found that:
5:42.5 ----- 342 seconds (43psi fuel pressure)
.055 LPS = 3.32 LPM = 199.47 LPH :: 52.77 GPH


6:31.5 ----- 391 seconds (70 fuel pressure)
.048 LS = 2.91 LPM = 174.47 LPH :: 46.15 GPH

I'm thinking I've either got a voltage problem, some sort of a restriction in the fuel lines themselves, my fuel filters are clogged (the in-tank sock is stupid old, and may actually have it too low in the tank), or the pump itself sucks...

Lets just say that I'm less than happy... Gunna start with getting a replacement fuel filter (it's possible that bits of my old 044 are clogging it) and double checking where my pump is physically located in the tank. Unfortunately I can't monitor the voltage at the pump while testing this at home =(

[JL1RX7]

You need a good meter?

[Fendamonky]

Yes, and a good man to work it


Do you think you'd be free to come help re-run the tests?

[JL1RX7]

You just know what to say! But let me know what afternoon you want me to come over.
