Hey Paul, as discussed - I used to run 044 in tank, changed to Walbro 460 for e85. Nearly kept up with demand but was on the edge and needed surge tank for track. I considered a number of "big single" fuel pumps - but most American gear I looked at had "duty constraints". ie not to be run at full duty for more than X minutes..

also, mixed results on 'noise' depending on who you talk to. Have sat in a few cars with Aeromotive, Maganflow etc that all you could hear is fuel pump.

this is ok if its a track car only - but to me, even a track car with a quiet pump means you can hear 'other stuff' that you want to hear.. so if you can get performance AND have a quiet pump - then why wouldn't you. Considered speed controlling these and even bought a Fuelab to do just this but did not go ahead based on other factors.

I think there is something to be said for OEM manufacturers. Generally cheaper (replaceable easily), reliable, often quieter, less amps draw (sometimes).

Running e85, I wanted no 'corrosion' so surge tank had to be completely anodised throughout. There is anodising and there is anodising. You want Type 3 Hard anodising done if you get it done locally - this stands up best but it is not 'by default' what you get - you must ask for it.

All lines are Speedflow Series 200 Teflon lined. No corrosion and no smell.

I ended up running a radium surge tank which is well made, properly anodised throughout and holds 2x Walbro 460 e85 pumps. Could have fabbed our own but why reinvent the wheel when this was a good solution. I only switch the second pump on under high load, so it sees very little duty (so it should out last the main one). With e85, there is much less chance of engine damage if you lean it out... and remember a big single pump can still 'slow down' over its life, so the argument there is.... arguable. At least when #2 pump fails you know about it. A big single slowing could catch you out over time.

regarding lift pumps, people have mentioned you can use another Walbro 460 for that - BUT, check out their current draw. They draw big amps even with no load or pressure.. about 10A from memory. If you are at full noise with all three pumps going at 20A + 20A +10A you can be drawing 50A for fuel pumps! (admittedly only at certain times)... with all the other gear we're running and CDI/fans etc... you want to keep it down where you can

I use an e85 rate Pierburg Lift Pump which only draws about 2A and easily keeps the surge topped up.

End result is I have a fuel system that you cannot hear even if you put your ear to it. It is capable of well more than my cars puts down in HP.

Parts are easy to get locally for replacement. All pumps are submersed in fuel - which I also believe keeps them happier in terms of temp and environment. ......and the surge tank is pretty to look at. Bonus. :)

Sure - its one of the most bling things on my car actually. Normally its all about function and lightweight, but went a bit overboard with a CNC aluminium "shelf" to fit a lithium battery, the relays (hidden behind battery when installed), surge tank and holders for the canisters from the AST Suspension.

The surge tank can take up to 3x Walbro 460 e85.. I run just the two. Pierburg 2A Lift pump in tank.

Hater! :)

I have a Mangafuel Protuner 625 that doesn't need PWM and doesn't have runtime restrictions (I have done hundreds of KM's then done 1000m drag runs without issue) but it's a noisy f**ker. I'm constantly considering the same option as our male model friend here, twin Walbro 460 pumps. I had one in my last green car when they first came out, fantastic pumps and almost silent.

That setup is mint, Matty.

As I said on the phone today, i've bought one of those Holley dominator 1800 pumps. By all accounts it should satisfy everything that gets thrown at it.

Bit of an update.

I finally got the car home. Huge issues with injector baskets filling up with this super fine silt. Its small enough to get through the 23 micron filters I have post pumps. The baskets have been cleaned about 6 times, fuel filters twice. The intank pump was flogged so a Walbro 460 went in as a lift pump. Definitely a whole fuel system clean out is in order. I have a few large 6 micron fuel filters coming also.

The modified transfer case has settled the car down alot too. With the GT Pro in the rear set to medium, it was very taily. It feels much more planted, can get on the loud pedal earlier. Win win!

The tune has been relaxed also. Boost controller is turned off, 3 degrees of timing taken out and 6-7% more fuel across the entire map just to make it super safe with this fuel problem. It still went onto make 415rwkw. Did a comp test and its 190 psi across all 6 pots.

The box is great. Definately "woke" it up. The clutch is better than expected also.

What the intank sock looked like.

Bit of box porn.

Dang. You make me think dumping this old wore-out box on the curb and getting a fresher, younger, but more expensive box that may let me thrash it more before complaining.

Wait...we aren't talking about wives?

For shits and giggles I took a video of the warm idle just before the compression test. On E85 you would hardly know it has cams in it.

A bit of box action. 415 KW, 19 PSI, super relaxed tune.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
