I'm good with the opels

 

You run 91 on 6758 with meth. Opels are overkill for you

 

Maybe i
ll just turn up my fuel rail pressure higher cause #Yolo

 

Wow....

Sounds like another business opportunity knocking for Nostrum Energy??? Maybe???

 

Sounds like we've got out first volunteer. LOL this will be a good add-on on your 7163 build thread.

 

might as well see what that ldk block will hold

 

I was just told by robk that pwerks has just come out with a direct swap in tank fuel pump for the lnf that can flow enough to support 700 hp.

 

Go drink aids.

Won't matter. The HPFP is the bottleneck. Once that's taken care of, everything else makes sense but only until then.

Look at any other DI platform; They need an upgraded HPFP prior to any other fueling mods. Hell, we should be grateful to GM for what they provided from the factory. Poor MS3s need a HPFP upgrade after doing minor bolt ons and a tune. Same with the VWs...

 

I'll test that **** too!

Either way I'm buying injectors

An in tank pump isn't the issue with the LNF it's the HPFP and until these come out injectors.

 

But if you increase the size of the injector, more fuel can be sprayed at the same pressure. Now I havent looked up or calc'd out what the same fuel volume the hpfp can move for a given pressure or per stroke of the pump.

I know VW's have a poor design cam on some of their engines and have improved it for better pressure and flow control on newer engines.

 

you increase the injector size, the pressure needs to be higher to provide the same flow or volume per sec.

Put your thumb on the end of a running hose = current stock injectors and stock hpfp.

take your thumb off = upgraded injectors and stock hpfp.

Attach a high pressure washer after the faucet = upgraded hpfp.

 

No, you're flowing less water with the pressure washer than an open hose your analogy doesnt work we have a pump and a nozzle involved. Pumps flow more at lower pressure, and nozzles flow more at higher pressure, but increase the nozzle size and decrease the pressure needed to reach a volume.

You increase the pressure at the pump to allow more volume to inject in the window the injector is open, increase the opening in the injector and the pressure required decreases. Think of water flow through a 1" pipe vs a 2" pipe, the 2" pipe will flow the same amount as the 1" at a lower pressure, increased pressure on the discharge of a pump requires more energy to flow the same.

Yes there will be a point when the pump can't keep up, but without connecting the injectors to the current hpfp we don't know, nor does bosch really give good data on how much volume per stroke of the pump (or at least I haven't dug into bosch data for our hpfp data).

Going to larger injectors in the stock fuel pump is standard with the LSJ, it's only at a point do they out flow the pump. The opel injectors everyone was so amazed by the 10% increase, without changing the hpfp, this is the same idea. Sure some major builds may outflow the hpfp, but those people will most likely be the exception. Most would want these to run e85 on a stock or slightly larger turbo.

 

Over kill or not, they cheaper than new stock ones lol

 

Lol good plan tom

 

Ok so I have 100% honest question for you guys. Can the stock injectors supply enough fuel to support full e-85 with the stock k04? If not will the opel injectors allow it? or should I just hope these injectors come out?

 

Cam lobe upgrade and opels should get you there.

 

Plan? I'm talking bout opels. I wouldn't get these cause I'm at the limits I'm going with my car

 

I learned all about fluid movement, but I use it for hydraulics, its completely different when you add in extra pumps and nozzles

Yes. These injectors are not requured for anyone under 500hp in my opinion. I've heard of guys running full E with just the lobe I have not personally tuned anyone like this but on the R I recommend both injectors and lobe if wanting full E. I get my guys to run E47 it's my fav. Fuel upgrades go in this order first lobe then injectors and if you still need more a 5th. I'll have a lot of fueling data in the months to come as my guys start their tuning on their new builds!!

 

I meant like for you getting them since they are cheaper than stock(talking about opels)

 

So then wpuld it be safe to safe to run full e-85 with the 6758 or 7163, these bigger injectors would be needed along with the fueling cam?

and since these injectors "will be cheaper then stock" wouldn't it be cheaper to get these over the opel injectors?

 

There's more in ur car Tom. And also you and I are cheaters because we both have meth which is basically a 5th injector and a big one at that.
