They are saying the ipw will be lower comparatively, meaning the injector itself is more efficient because of their design, not the size. But it's hard to say if it will make that big of a difference. Can't wait to see some results/data on several different fueling setups. Git r dun zzp!

Also at 50% better I wonder if they have a solution for the small lines and hose that connect the HPFP to the rail and the main fuel line to the pump so we can run bigger lines or AN hose

Been doing some E47 tuning on a 71 with Opels and lobe and it barely holds 15mpa FP. Going to a 50% bigger injector is absolutely pointless without a much better flowing HPFP. Then Opels and the pump would cover 99% of guys still leaving these injectors useless

I was thinking they were also working on a higher output hpfp along with these.

I think so too

Well even if they do, the HPFP and Opels will be plenty for guys. I could see over 500hp on full E no problem. I have a customer and his IPW is ok around 500hp on E47 with lobe and Opels his FP is 14.8 to 15.8mpa. If he had commanded pressure his IPW would be way lower and that would accommodate for the 15% more fuel requirement of full E

So this thread was started in February and we have no new info. I am not at all interested in the injectors I believe they are too big and basically useless. But a better flowing HPFP would be a great upgrade!! I just want to be able to run commanded fuel pressure on my Opels

I'm gonna guess that it didn't work or wasn't reliable enough. Pretty sure Ryan drove a lot over the summer and did compete in at least a couple of events, so he should have logged enough time to see if it would work. Don't know how many people they had testing it, as I haven't heard anyone talk about it on the forums. I'm with you on just needing the hpfp unless you are going for crazy power.

KMO43

Well I hope they tested each part individually because with the fuel line size on the car especially the hardline into and out of the HPFP will never flow enough for those stupid huge injectors. If we had a 10 to 15% better flowing HPFP and opels that would be good enough for a lot of ppl

We are doing a lot of testing with a lot of variables on a lot of things.

Sorry for the ambiguity, but give us more time folks. It will be worth it.

THIS JUST IN

zzp the first to complete a full port injection swap on an LNF

Scythe_Snake

False! lol.

We love our DI =)

Put me down for a upgraded HPFP for sure but only for injectors if they are 30% bigger not the 50% ones being developed.

Going to past this here as well (as we did in the LNF Injectors thread):

Sorry guys, we have been a bit busy as of late. We will prepare a flow diagram with the LNF, LHU and LTG injectors (Nostrum & Stock) so that you can see the flow rate comparison. Give us a few weeks because GM LT has been eating-up all our flow bench time.

One problem we found last year, is that there is no ability to drive the drive current on the LNF platform. This is a big problem for our LNF high flow injector, and is the main reason we stopped build on that part number. Without being able to increase the drive current to accommodate the increased solenoid gap in our Nostrum injectors, there can be issues with opening speed at low load and also flow restriction at high pressure (high load) because of the increased hydraulic force acting on the back of the pintle at the higher pressure, which require us to drive a higher current with the big solenoid gap. This is not an issue with LHU and LTG, since HP Tuners has a great tool today for injector drive command. We are working on preparing HP Tuner files for LHU and LTG, and hope to add this to our website when we launch the sets / kits (with pumps) later this year. But for LNF, only the guys with stand-alone controllers would be able to run our high flow K-DI injectors, and we don't have many takers.

Stay tuned for the flow charts

ALSO - Just FYI, we will be selling injectors, high flow pumps and base tunes soon. We still sell through our dealer network, but I think most of you are skilled enough to handle this, and we are packaging the data in HP Tuners to make it easy.

We have been running the high flow LTG High pressure fuel pump with our LTG high flow injectors on our Cadillac ATS for more than a year and are satisfied with the performance and driveability. We will be exiting the ATS and moving into a new Camaro with the LTG engine this year. (My engineers still won't let me get a Buick Regal GS with an LHU. ) However, we do have a High-BMEP project (50bar BMEP target) at our laboratory that is running the LHU high flow high pressure fuel pump, our injectors on dyno, with our water injection system and they have performed very well.

We will try to work harder at keeping everyone updated and providing as much technical information as possible.

Well that's disappointing for us lnf guys. Glad the Buick gs and caddy guys can benefit though.

ecu swap wouldnt be terrible i dont think
