ZZP Fifth Injector.
In our testing, the factory LNF pump flows the same as the Walbro, if not slightly more. The Aeromotive pump flowed WAY more than either. I don't have the numbers on me, but it was something in the 25% range higher than the Walbro. I ran the Aeromotive pump past 600whp on 90% ethanol. Not 90% E85/10% gas, but actually 90% ethanol- E90 I guess you could call it.
I know what your saying but that wouldnt be as reliable. This actually y's off the main fuel line, which is the reason for the bigger fuel pump, and uses a 60lb/hr injector. And like you said the injector will come in at a certain boost and is a progressive controller to add fuel as boost increases.
You can do that with this 5th injector kit. Add in a cell with methanol or C16 and it's own pump and this kit makes a great meth kit.
The injector replaces the EVAP solenoid. The EVAP then mounts on the block that sticks out towards the front of the car. It's hard to see it in the pic, but there is a mounting pad for the EVAP. The original EVAP hole aims right at the center of intake directly above the throttle plate, so the fuel mixes very well.
... What sounds more reasonable is making a port fueler type but running the stock manifold..... Run four injectors and they are boost referenced so they'll com in just like your kit .. because to me, running one doesn't mean all the cyclinders get the same amount of fuel. Have you guys tested the flow and egts on each cyclinder and runner?
Matt you answered my question lol. I just assume.each cyclinder would be different since flow will be different. But its a great example of ingenuity lol.... Work with what you got.
Yup. I've been running this kit for a while. I think my dyno numbers and track times show how well it works.
Right now I'm running e47 w/ a 7gph meth nozzel with a 50/50 mix. Its a devilsown progressive kit
If you are running our fuel pump lobe intake cam, then you can already support E85 on a typical 450whp upgraded turbo setup without this kit. If you run this kit instead of the larger pump lobe, then you can stick with the factory in-tank pump and support similar power levels. If you are going past 500whp on E85, then you want the pump lobe, 5th injector, and Stealth pump.
It should be on the site soon. We just need to put together the cost breakdown and finalize the price.

I'm not officially an engineer yet but wouldn't this make cylinders 1+4 run leaner than 2+3? Being closer to the injector in the manifold? I don't know exactly what the interior of an lnf intake manifold looks like, just my thoughts. How would you be able to tell if 1+4 are lean and 2+3 are rich besides running 4 widebands in each exhaust manifold port?
