For Price I'd go with diesel auto power. For quality you will want something that is flow honed like ddp. Sadly, this is one of those things where you can't have both cheap and quality. Ddp despite what some people will say, do indeed make a fantastic injector

So going with ddp2's would be a good choice for a mild injector?

I do. I owned a set of their 55lpm injectors in a VE and a set of their 90hp ones in my ppump motor before I popped a hg and found cracks between the valves (not injector related, PO stupidity related is my guess). To date, they are the best injectors I've owned.

In all I've ran stock injectors, a set of ddp 55lpm VE, a set of 90hp ddp ppump injectors, contag!ous tips in stock injector bodies, and DAP 5x16 tips in stock injector bodies.

The ddp for both motors were by far the best. the DAP set is second. I'm thinking at some point I'm going to send my DAP injectors away to be flow honed and balanced.

On that note, RC do you think that shop you had yours done at would do mine and ship em back to me if I paid shipping both ways and for the honing and related costs? nobody around here has the equipment for it.

What I don't like about ddp is that they use marine spray angle in their sticks. Other than that the reason they work so great is because they flow hone their nozzles.

A flow honed nozzle usually can/will flow about 15% more than a comparible lpm nozzle size that isn't flow honed. Meaning a 55lpm edm nozzle will flow less fuel than a 55lpm flow honed nozzle. Keep in mind that the lpm numbers are with air, not fuel. Fluid doesn't compress as well as air, therefore gets interrupted more by sharp corners.

Yes, my guy will do your nozzles... pm me for his address, etc...

In fact you can call me if you'd like.... two0eight-2one5-56five9 call/txt anytime.

that goes for anyone on this site.

What kinda differences did the 55 lpm make over stock sticks

I had 72lpm DDP's (4+) before I went to my swimming pool draining nitrous injectors, and I liked them. Good power, and no drop in mileage. I have a set that I am going to switch to for street driving once I lay down some good track times with the 5x25s.

on a stock motor with only a cheap home made intake, stock dyno, dennyt dyno, then ddp4 55lpm injector dyno with no tuning: Put 'er on the Dyno Sat. Baseline, DennyT then DDP4 - Dodge Diesel - Diesel Truck Resource Forums
^^ Keep in mind that I hadn't touched my fuel screw at that point, and had done virtually no tuning. I did however make sure I had full throttle travel and had switched my throttle arm to the inner hole and put spacer washers on the pedal cable so I had full throttle travel.

after all that I then added 4" exhaust and an he351 and went to 248hp uncorrected but lost a bunch of tq, but that, i am guessing, was because I was starting to wear out the converter and was starting to push past it's working power i think.

When I switched to the he351cw and 4" exhaust I could turn the wheel all the way to one side and step on the accelerator with no braking whatsoever, I would spin the truck 180* the other way and just completely roast the tires and not move forward. Again, with no braking at all. But then the transmission (or the converter, idk which) started to not grab as much. By the time I hit the dyno it was noticeable. my old dodge in that state was far more fun to drive than this ford with the new motor is. The ford is much heavier and the LS rear doesn't work at all, where as the LS in the dodge worked perfectly.

EDIT:

It would appear all those links are broken... lame. well this should be a link to the album on photobucket

So..... .................................

For the record. I have had DAP injector nozzles tested and installed by "my guy". Keep in mind that he is a die hard bosch gentleman. He said that "surprising to me with what I would of expected, they made a very nice chatter and were all dead on the money within lpm of each other."

This by no means has any bearing on the reliability of a nozzle or anything to do with buying a full injector from DAP, but the nozzles themselves tested out well from them.

FYI

We will be offering nozzles with extrude hone and even closer balancing. Hoping to keep the price within about $30. Great improvement for a small cost. Beta testing on our SAC extrude hones nozzles should start at the end of the month
