Simple is good, though I'm not really sure what else is out there in terms of big single intank pumps... Anyideas?

It'll need to flow well and truly more then a nismo

There are plenty of mid size to very large single pumps available to support your fueling requirments.

Saying that, I put a deatschwork pump in my daily driven stagea and I'm pretty impressed. I'd be staying away from bosch pumps with e85.

Also, have a good look at your fpr. Make shure it has a large enough return 'hole' and fitting thread.

My fuel system will be supporting 500+rwkw, up to 400hp of nitrous on e85- not a surgtank or multiple row of pumps to be seen. I wont be having any issues with surge either... I'm still trying to figure out why people are lining up 6 or 7 044's in the boot???

Cheers

cheers for the reply mate, not sure i need that many pumps though :thumbsup:

anyway decisions been mate

My mate Wing is designing a new surge tank set up so im going to be the test dummy for that

basic specs atm are that it will be a

-baffled surge tank, approx 300mm high

-appoximatly 5.2L capacity

-Running 2 Deatschworks pumps that will be in fitted into the sure tank (will help with cooling and noise)

-will be CNC machined so no welds

Apparently the tank can run up too 4 pumps in it, with the option of either a Deatshworks, Walbro, aeromotive (044's have too large a frame). We chose the Deatshworks becasue its ethenol freindly and we reckon its a better pump overall (lets not start a which pump is better debate :nyaanyaa: )

the stock feed and return lines will be made both into feed, with a nice big return line back to the tank, probably -8 or-10

Will be posting up some pics when its eventually done, will probably be another 4-5 weeks untill we get the finner details sorted

cheers

I would also look at switching the secondary pump. There is no use sending more flow to the front than what is needed. You will only end up heating the pumps and reducing the flow when you need it.

Interestingly my GTR went 618hp on the hubber dyno (so say around 430rwkw on a roller) using CSR E85.

Car has a lift pump to a surge tank with single external 044 and then standard lines (both feed and return) to a Jun rail and Nismo reg...

1200cc injectors were at 74%

I was surprised, would have thought it would have run short of pump well before then

Single 044 flowing more than 350kw on e85???

Sure ur temp probe isnt on minus 77 degree's :P

Don't worry I was as surprised as anyone haha

Mind you it was only on 20psi so not huge fuel pressure and it wasn't making the best midrange with the T88 :)

Correction was turned off so no fudging figures (but that hubber usually reads 7-8% higher than a roller)...

      Duncan's V37.......race car?

      By Duncan · Posted

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
