Im looking for 1600cc high impedance top feed injectors, which one should i choose and where could be a good idea to buy/order them?

They are going to be used in a e85 project.

Another thing would be fuel pumps.
I guess the 255 walbro cant make it on its own. It would be smart to use two pumps? which ones and how/where should they be mounted?
The project will be aimed a bit over 500 hp

Thanks in advance

Why the need for such large injectors?
There are a couple of sellers on eBay who do a twin Bosch 044 set up with an fitting and filter all mounted into on unit.

my tuner actually recommended me the 1600cc ones, and told me the 1000cc (injector dynamics) i have already will not be a good idea when going for e85, since e85 burns a fair amount more mixture than gasoline.

ianbott

I see, sorry didn't notice the bit about e85, interesting project, i assume you're not in the UK?

scoobRA

yes, its interesting to see what comes out of this

no, im not in the UK

I ran deautchwerks flow match 750cc injectors to 555bhp with no problems and I now run 1000cc ID injectors and I'm at about 630bhp? So why do you need 1600cc injectors for 500bhp?

I also ran one 044 pump to 555bhp but after that I needed a few more pumps and a swirly pot

e85 ?

Steve obviously didn't read the above posts.

Also would you not need to change all fuel lines and possibly tank as E85 can corrode things.

scoobRA

All fuel lines well be replace anyway

10% meth but Dynamics has run 100% e85 on id1000cc with mid 600's bhp. I can't see how the fuel type can affect the fuel flow? Yes other things need changing but how can a 600bhp+ injector not flow 500bhp just cause its e85.


Forgot to mention I can run race fuel on my setup and get near/over 700bhp so whats the difference!!!

My drag car will be running 8 modified and flow matched WRX topfeed injectors, would that not be a better way to go with your project too ?
If you only want to use 4 injectors, the Deatschwerks 1300cc injectors should be plenty enough for your requirements.

Pump wise I quite like this as a kit http://www.nengun.com/sard/fuel-collector-tank
Fit it with 2 Deatschwerks 300lph pumps and you'll have a very nice fuel system.

MartynJ

Because you require approx 40% more injector capacity on E85 than you do on petrol.

I just checked an old thread for Duncan and on id 1000cc using greenergy 100% e85 he gets 643bhp. I'm not doubting your knowledge but if he only wants 500bhp? and that was on Zens rollers.

MartynJ

I quite agree, ID1000s are probably plenty man enough for 500bhp on E85, however I am myself of a nature to overspec, rather than underspec, so can see where the man is coming from.

i found some threads on nasioc where thay mounted two pumps on the stock pump assembly, in tank, i guess this could also work

MartynJ

It would, however I prefer the added swirl pot capability of the Sard tank.

bigsinky

martyn, would upping the fuel pressure not help?

MartynJ

Yes, but if IIRC ID1000 injectors require 4 bar base, to even get to 1000cc.
I personally prefer not to run any higher than that as a base figure.

would fiveomotorsport 1600cc top feeds be worth purchasing? ID seems to not have the 1600-s anymore, they were discontionued.

yes propably going with the surge tank, with two external pumps.

I use Injector Dynamics ID1600 cc injectors and get 780bhp to be more up to date Steve

Great injectors and are fine enough to idle well too.

I also use a pair of Fuelab Prodigy pumps (the smaller of the two pumps in the prodigy range) with an RCM 340 as lift pump.

Good luck with the project

If you cant get the ID1600 then the ID2000 still idle great and will give plenty of headroom

thanks for the reply dynamix.

They dont sell the ID1600-s any more, so i guess fiveO 1600-s are the ones i am going for. I ordered 2 hrc 290lph in-tank pumps

And yes, i am going to buy sard tank, just havent decided which one yet, i want it to be as small as possible but as big as it has to be (dual internal pumps).

So i am confused: how can a 170mm(W) X 185mm(H) X 205mm(D) tank have a capacity of 5.8 L ??

Any sard prducts resellers in europe? Or it has to be ordered from us/japan...

Those dimensions (which will be external) give 6447.25cc or 6.44725 litres so allowing for material thickness etc internal won't be far away from 5.7 litres.

now that the pumps and sard tank have been ordered, what about the fuel filter?

would the original fuel filter flow enough and is e85 friendly?

although it would be nicer to use all an fittings in the whole system, which is not possible with the stock filter
