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)...

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
