Twin Bosch 044's Setup Progressively

[01txr]

No havn't fitted pw tank as yet.

Was only running walbro in tank pump and only

Feeding 12psi into the to4z setup.

Being manual on street Tyres it struggled for traction as well fuel surged into 3rd gear even with 2/3 tank of fuel.

2.4sec 60ft, started to ping when slotted 3rd so got right off it, then decided to slowly feed throttle back in for 12.902 @ 116mph.

A week or 2 after that I had number 6 rod shatter.

So been building new engine since and not going to risk any fuel problems after spending good money.

Danny I though you wouldn't get that much of a current draw.

Wouldn't a decent battery cover the drain.

If not what about running a higher amperage alternator.

Running the boost presure switch to kick in the 2nd pump obviously is going to drain some power but if I run the voltage booster single pump it would still drain amperage.

Is it feisable to drop fuel pump voltage on a large capacity pump to slow the flow at light throttle.

Or will it strain the pump?????

Or just run high capacity pump continuously with return going to fuel tank instead of back to surge tank.

Less frothing and less heating of the fuel.

So what's the best fuelling option to run for our cars that I won't have to sell a kidney for.

Two options I'm concidering

Bosch 044. $200

Msd voltage booster $400

Total. $600

Holley billet pump or twin 044's. $400

Boost switch. $060

Relays. $020

Total. $480

My mate jay previous owner of chop ya (hi Torque yellow bf f6 780rwhp monster) was running twin o44's at rear and I understand how loud they can be.

I could here them over my engine at idle and that's me sitting in my car and his car beside me.

??????????????? Decisions

run the std set up for normal and flick a switch for drags/circuit work easy as that really so 2nd pump on as u want it

anything else your gunna just overcomplicate the system or id be worried it wouldnt kick in at desired psi if not used offen

wow this bloke knows something here.......................

Don't want to manually flick a switch each time I decide I want to pull out and over take. I have mashed the throttle on numerous occasions in the spur of the moment. There's always a gm product trying to run you. Or you need to merge into traffic, overtake some idiot that's causing a mile long traffic jam. Etc.

Maybe alot easier with a auto where you don't have to reach for the shifter then grab the wheel to fight to keep it straight.

Eg reach for a switch, select a lower gear then go. That auto gm just put a car length on you or going for a gap in the traffic.

I want it to switch on when required.

As I said earlier, my PLX o2 wideband/lambda gauge has warning as well as peak hold min and max values. It can also be connected to a data logger.

So if one pump fails and iam wot the gauge will warn me. I think I can even

Run a external warning light from it as well.

I'm thinking of running one for oil pressure and the other for fuel.

I'm also wanting to run a eboost2 so I can control boost per gear.

I read that the eboost 2 can switch on pumps, and other things.

That sorts the trigger for the second pump if I go with a twin pump setup.

When the pump turns on it draws a surge of current, you'd almost need a audio 1farad capacity to stop it impacting your electrical system.

When they are running they do not draw massive current. Its only the switch on.

If you are really concerned about running 2 pumps, get a single aeromotive pump for example.. they dont quite flow 2x 044's, but its a single pump.

Personally I run 2x 044's on a process west surge tank, AND I do not have rubber feet. The noise? Meh, I don't sit down whilst I pee.

My exhaust note covers most of it anyways. Not even my GF complains about it.

Having the return line go back to the tank will cause the surge tank to never fill up.. Making the unit almost useless.

Be a man, just run 2x 044's on a surge tank always on. You'll be winning then without all these concerns.

BTW, I run 100 octane.. People say e85 is quiet in comparison on the pumps, but personally I don't find the noise loud or annoying..
