Ill gladly ditch the 1ks for the 1300s

 

Maybe the administrator could split the thread? Lol

 

its not what I understood

 

so from whining to side busting were making progress

 

play nice kids.

jw you need to go to bed we got a busy day tomorrow

 

Lol ^^^

 

Sean and I know Vaughns car inside and out . I helped with tuning when the TVS was initially installed, discussed his engine build to the tiniest detail and have been working on helping him decipher the issues he has had since the car started to run again.

Sean and I have watched vaughn install return style, then install bigger fuel pump, then send that pump back to Deatschworks, then install bigger injectors, then rework his rewire system, then this then that then the other. We seen Area47 come down to tune and see if there was any issues he could help/address.

and after all of this Vaughn is still buying parts and trying new things because nothing has completely fixed the problem. I for one am tired of watching his car get all of these "ideas" thrown at it and not running right as ppl promise. So if I am in here asking questions its because I want his car to be what it was or to be something he can enjoy.

 

Truth

 

Those that know me know how particular i am with my car. I enjoy working on it at my pace.

When things become a challenge or limitation i try to mitigate in the smartest way possible.

Yes pump capacity is a limitation, but im hoping the setup i just installed provides the necessary fueling for my needs.

Balance shafts are another area where i have tried to avoid doing something but will likely delete them soon.

I may go bigger injectors as well but i want to see what the fueling and nitrous present on the situation

 

Going to a bigger injector and dropping fuel pressure will give you more pump volume, so if you need to that would be a good route to go.

 

How To Build The Proper Fuel System For Carbureted Motors - Chevy High Performance Magazine

I recall Area quoting Paul Yaw

http://www.injectordynamics.com/HPCalculator.html

Bosch 044 Fuel Pump Specs:
Bosch Part Number: 0580254044
Minimum Current: 12 Volts
Operating Pressure: 72.5 PSI (5 Bar)
Minimum Flow @ Outlet: 80 GPH (300 LPH)
Fuel Pump Location: In-Line
High Temperature Reduction: 8 GPH (30 LPH)
Weight: 1030 Grams (2.27 Pounds)

this comparison clearly shows that at the ecotecs normal factory desired fuel pressure 044 is the best choice in this comparison. So far so good.

Fuel Pump Connections:
Inlet: M18 x 1.5
Outlet: M12 x 1.5
Electrical: Positive M6 / Negative M5

 

do you have NBS?

 

Not yet. He is doing a delete soon

 

The bosch 044 out flowed everything !!!!

 

should be wiring everything this weekend

 

it may have but at what cost of running a reasonable base pressure if you need to jack the base to the moon then you defeat the purpose of a return system

get it done

 

what on earth are you talking about? I am no expert but its easy. Pump is better, thats a fact the data is there; Japetr's system is good, thats a fact that race configurations show, (and you have no experience with this system) but then neither does anyone else here as far as I know. I assume Japetr will run about 58 lbs pressure to start. And will go from there. without limitations for that part of the system.

so thanks for the thread Japetr, sub'd for your next thread.

 

what is 1 purpose of converting to a return fuel system that's referenced to be able to run a low base pressure so you can have better injector control with huge injectors so by having to run back to stock pressure(58psi) is not helping matters with large injectors

your(which I assume is a cloned system someone else designed) surge tank system is not some special over complicated out this world unicorn system your making it out to be

 

Tune us currently set at 52

 

if you can lower the base some the better

 

Mr B its thanksgiving so I will join with everyone and give thanks for turkeys.


surge tank systems are far from new. Did I not say that its SOP earlier? That it is racing practice? Its just a tube with fittings in it. I am not sure why you are taking this tack since the get go, maybe its your thanksgiving mode?

Mine is totally not complicated. What is new, that no one has EVER done before, is mount it on a Cobalt , where it is located.BFD. Good job John!!

Happy thanksgiving Mr. B.

try to fly like an eagle.

 

Only 1/2 right. The point of a pressure referenced system is to run a HIGHER pressure than normal to meet delivery needs, while allowing vac to pull the pressure down at low engine loads for better idle characteristics.

 

At a 58 psi base he should only be running around 50 at idle vs stock 58 at idle

 

I don't need to try to be an eagle and I am one soaring bad ass eagle

the second point is under hard acceleration where dose the fuel go and stay to the back of the tank if he dose not keep x amount of fuel in the tank then under a hard pull he can pump the sump and surge tank dry and with the amount of fuel he is going to be shoving into the engine it is more then possible that that can happen with or with out a surge tank what is needed is a rear pickup to prevent that

happy thanksgiving to you also Mr Powell

 

I totally give up. Mr. B we gave you the math.you do it. i am tired of this bs. you will not starve a one litre tank with an operational lift pump and pressure pump even at 1000 hp. really.
go eat some turkey and get out the calculator. the flow and delivery tables have been posted.

then show us the math to prove your point.

right.
good nite
