Thanks...and honestly...I was testing you. I know very little about injector design, and trust the experience of the experts like yourself to help guide me.

For instance, if you have a 4 orifice injector, is the injecotor designs to spray at a certain angle, as to hit the valve and intake track at the proper angle?

I would like to test out a set of these injectors, when the time comes.

You correct on the fuel system. Stock 350Z system is returnless, and worthless for F/I. Most people upgrade to a return system, with a rising rate 1:1 FPR, and stock FPR plug in the tank.

 

I got 6 stock injectors for sale if any one wants to do this without pulling theirs

 

Booger, sent you a PM about your injectors.

Sharif, I think I now understand what you are asking. The vast majority of the multi orifice injectors (especially high flow multi-orifice injectors) do not "aim" the fuel charge towards the valves. They usually spray parallel to the injector itself. This will usually result in a single stream spray pattern sometimes with distinguishable lobes.

Some high end injectors actually do have directional orifices, and don't get me wrong, they work great. But traditional style injectors have been proven to work very well also. The intense heat and pressure of combustions chambers will pretty much atomize whatever finds it's way past the intake valves.

 

I got 6 as well...anybody give me a pm after booger gets rid of his, don't want to steal his sale.

 

UPDATE:
I just flowed a set of APS 440's from their turbo kit. I have built the DeatschWerks 440's to mimick the flow and spray pattern of theirs. They are going into a car that currently has the APS kit on it and we will be datalogging AFR's to show equivalency.

440's should be ready for market before the end of October. 550's will be comming out after that.

 

another update:
beta testing is complete. Everything worked beautifully... start up, driveability, on/off throttle afr's, etc. We also dyno tested the injectors vs the APS injecotrs. The test vehicle actually put down 10 more whp with the DeatschWerks injectors than with the APS injectors. Be looking for a post soon from BriGuyMax.

 

how was this achieved? less flow than the Bosch injectors that APS uses hence a higher AF ratio (going lean)?.. i'm assuming nothing else was changed in the car and runs were done right after each other in almost the same conditions on the same dyno

 

Got any high flow injectors compatible with Methanol?

...or any suggestions on where to find them?

Side feed, top feed, any make or model. I just need it to be compatible with methanol and very high fuel pressure. Fuel pressure is variable from 70-200 psi.

 

Same car, same mods, same dyno, same tune, but on different days. I belive both were adjusted to std conditions. Anyways, it doen't really matter, I wasn't trying to prove that m DW injectors are better than AP, just that they are comparable.

I flow tested both the DeatschWerks and APS injectors. The DW actually had a better balance and IMO, better atomization. So it could be that the afr's were more consistant from cyl to cyl. They were the same size. In fact, Brian told me the DW injectors were a litttle fatter up top. I have yet to see the dyno graph yet. TUAN

 

nice.. has the thread been posted on the results.. always room for improvement over the bosch injectors

 

Anyone used these injectors over RC's???

Would like to know peoples opinions on the best injectors out there.

 

how about the injection pattern? Is it better or worse than oem?
