Went 560 rwhp today on 23psi, and then started to lean out again.

Current setup is an 044 intank feeding a 044 in line - all on 98 BP fuel.

I think Ill have to go twin 044's and a surge tank to overcome this problem. Wanted to keep away from fuel pumps in the boot etc but cant see any other options now.

Simple;

044 in tank ----"Y" piece---- 2 x 044's supplying engine

With the 2 x 044's mounted externally (under floor), no surge tank required.

Cheers

Hey Gary

Just trying to find room underneath to put the 2 pumps ( in a safe place ) is an issue in its self :-)

Will 1 x 044 intank be able to feed 2 x 044's inline ?

hmmmmm i like this idea

what kinds of power would a setup like that be capable of supplying????

i would like to know this aswell, as i jsut found out one 044 pump might be border line at around 450-500hp.

im not sure how much extra flow your gonna get by running 2 044's behind the intank one. sure your gonna get extra flow by eleviating the strain off the single, but how much extra?

personally id have a low pressure hi flow pump intank supplying a surgetank under the car than 2 044's feeding the rail

How much are one of these A1000's ? And who sells them ?

I know magnaflow make a pump rated at 1000hp - I havent compared the actual flow rates etc yet.

I dont think Ill get much more out of it on pump fuel and with a cat ( maybe 600 rwhp ) - but its better to be safe than sorry.

Why not just get the Aeromotive A1000? by the time you have spent the money on 3 044's you have basicaly spent the same $$ figure.

i've bought my entire fuel system from summit, awesome service and delivery :down:

Has anyone removed the bungs from the oil gallery that feeds the mains? there is one in each end of the block between oil & water pump, seem to be about 12mm diameter solid steel pressed in (not a welsh plug). I have removed them from an old RB30 block by drilling out, before I do it on my good block I want to make sure you can get a replacement. Anyone know about this?

You don't have to put the 2 x 044's side by side, you could have one under the bonnet if you wanted. The only location limit is how far you want to run the wiring (voltage drop).

An 044 pumping against zero pressure flows almost twice as much as at it's rated pressure (72.5 psi). Plus the 2 x 044's suck, creating a partial vacuum at the outlet of the supplying 044, hence further increasing its flow. As a comparison, 1 x standard R33GTR pump keeps the surge tank full with 2 x 044's supplying the engine.

1200 bhp should be no problem.

Just be aware that you have no surge protection without a surge tank, so hard launches or cornering G forces WILL interrupt the fuel flow whenever the tank gets much below half.

Mine is running in at the moment, started it up on friday night!! Anyone got any tips for the run in process?

PS: Loving the torque!

As reported in many posts, I have used the same basic running in process for lots of years and on many engines;

Castrol GTX (the basic no frills mineral oil) with new filter.

Run engine for about 1/2 hr or until well warm.

Change oil filter. Engines can have particles in them that acccumulate during the build/maching proces and they need to be removed from the engine ASAP, these are caught in the oil filter. If you leave them in, the oil filter can get blocked and so it will be bypassed ie; no filtering.

Check the basic tune on the dyno or on the road with portable lambda sensor.

Drive to Bathurst and back, around 500k's, lots of varying conditions, up and down hills, freeway, long climbs etc. Don't rev the beegeesus out of it, gentle but firm, change throttle openings often, no slogging it in high gears with lots of throttle. Much better to load it up with partial throttle openings going up hills.

Drain the GTX and remove the oil filter.

Refill with Castrol Edge 10W60 and fit a new oil filter.

Do leak down test, if OK then final tune on the dyno.

Go racing

Cheers

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
