Got my new EDM's from Don M yesterday we were looking for something to run maxed out in the EGT range of the PDR 40 and he nailed it!
I installed them in about 45 mins last night (I was anxious) and out for a test drive!
I had a set of Dons honed stage 2's while Don reworked my Nozzles. So anyways out on the street. The injectors idle much more smoothly I noticed that first off. Smoke is typical of a dd 2 if you absolutely mash it on 5x5 from a dead stop any injector is gonna smoke at this point.
We all know when the smoke and it may bother some or others not at all but say from 50-MPH to 75 MPH I could smoke the honed 2's like crazy the EDM NO SMOKE when rolling into the throttle heavily that is a HUGE plus for me!
If you stand on it say in OD for the downshift this is my auto you get a small puff very small compared to the honed 2's

Now the HP!
Im sure you all are wondering and my apologies for taking so long I maybe should have started with this! As I don't have a dyno yet its seat of the pants well HP feels stronger then the honed 2's all along! I also noticed boost to be about 1PSI higher under WOT so more fuel! Now EGT's man these things are cold I was hitting 1400 + with the honed injectors these are 1300 maxed out running WOT up big hills and stuff.

These are truely excellent injectors and work perfectly!

 

Man, i was set on getting the ddII's this winter. now, these edm's are sounding awesome. I'm having a little trouble understanding how they add more fuel than the II's (1 psi higher boost) but smoke less overall. That means they must atomize the fuel much better. sounds like a good injector. are they about the same price as II's, or not? what made you switch to these and dump the II's?

Jason you answered your own question of the atomization! If you want a price not my departement Contact www.wildcatdiesel.com or Don M personally he makes em and can answer any questions.

 

Jamie, one more question. are there different stages of those injectors and if so, what stage did you get? It sounds like the setup i am after.
thanks,
-Jason

 

Jason there are many different stages. You should contact Don M via PM he will let you in on the stages he can also custom make em to your preferences like he did for me. He just kept sending em to me until we found the perfect ones for my truck and combo! He's probably one of the greatest guys I have ever delt with.

 

Don is good to work with. I added a set of his Mach 4s last week. Going from dd3s my engine runs smoother throughout the powerband. I really liked my dd3s, but these hit so much harder at a lower rpm. I do have to be carefull with off boost smoke but once up to boost all the smoke clears up then hold on. Tim

 

I tossed some notes out about Don's injectors in 12 valve thread, but I'm going to throw out in this thread too:

We've had fantastic success with Don's Formula 1 EDM injectors. The EDM process, coupled with Don's own custom tip design, allow an injector to be built to much more precise flows and the spray patterns are spot on to what the 5.9 Cummins needs to properly burn the fuel. Don also custom tunes each set of injector to the customers truck to ensure that you're getting the most bang for your buck.

The F1 injectors are available in following stages:
Mach 1.5s - 80 HP
Mach 2 - 110 HP
Mach 3 - 125 HP
Mach 4 - 150 HP
Mach 5 - 160 HP

In addition to the above stages, Don can build a set that will notch you in between the power levels, should you decide you want it.

As for results on the street, we've found that a set of F1 injectors will smoke about the same (in some cases, less) as a set of extrude honed injectors a size down. For example, the Mach 2's at 110 HP will smoke about the same as a stage 2 extrude honed injector (80 HP). The bottom end/mid range torque of an F1 injector will also be higher than a comparable extrude honed injector. As an example, the Mach 3's will deliver about 150 lbft more torque at 1800 RPM than a set of SuperMental injectors.

Strip performance is also great. One of our customers is running a set of Mach 3s, KSB1B, PM3 Comp, BD RAD, ATS tranny with EmJay controller, and he's turning in 8.33 1/8s and 1.76 60 foot times with 285 tires. Now if he wouldn't sleep at the light (right, Meach? ) those times would be down to an 8.1 1/8th and probably a 1.74 60 foot.

Our customers have also had some pretty good luck in the sled dragging areas. Another customer/dealer in the east, running an older set of Mach 4s (not as refined as the current Mach 4s), PM3 Comp, KSB1B, and DTT trans with EmJay controller took a 3rd place with his street driven truck against trucks running twins, nitrous, tires and ladder bars.

Sorry for the fairly lengthy post, but if you're looking at injectors, I _heavily_ recommend you look closely at Don's Formula 1s. They average about $100 more than a comparable set of extrude hones, but the product is worth every penny ;D

I have a custom set of mach 4.8 that are as smooth running as stock injectors no pulsing like a big set of extrude honed nozzles that i used to have.These injectors rock,with a single charger there a little smoky but the twins are going on in 2 weeks so well see what they do.Don is the man.As soon as the twins are on i will post some dyno numbers with these injectors & then i will try some other injectors that don is going to send me & ill post those numbers as well.You still have those nozzles on the shelf for me Don? .Kurt.

 

pushrod,
thanks, i think this has made my decision. I believe in getting what I pay for. The only thing holding me back from the larger extrude honed injectors was the smoke. This is great.
Thanks again guys. Also, does Don have a website I can check out?

And to add a little more to this thread, I just got a phone call from Don. He sounded like a little kid at Christmas time, as Nate (Idaho_CTD) had just pulled an awful good dyno run. Nate was able to lay down a 700 HP (corrected, uncorrected was 644 at 60F and 2200ft) run using some custom Mach 6 injectors from Don. I haven't had a chance to dig, but I'm pretty sure that makes Nate's truck the highest pony, stock VP44 equipped 24 valve truck on the road. I think he's even pulling more pony than the tricked out VP44 crowd, but again, I haven't had a chance to dig into it yet.

Congrats, Nate. Thats a helluva truck y'got there. You should be able to haul more tators now

Just a note... reaction times have nothing to do with E.T.s. You can sit on the line for 20 seconds and still have a 13 second timeslip. R/T only matters when racing (bracket or heads up).

Well actually sheep boy it was 700.1hp and 646.8hp uncorrected (77* dyno temp @ 2700' elevation) ;D. That makes it almost exactly the same as Nowells may madness numbers. I guess now I'll have to build up a new set of twins too and talk Don into another set or two of nozzles. Then maybe a super hot rod vp will put me over 800hp. Who says the p-pump crowd is the only ones that can make power?

 

Good job Nate!Hey Don can i get a set of Nates nasty nozzles. .Kurt.

 

And before Nate has a chance to chew me out here too , Fuzzy Butt Don gave me some bad info. The proper numbers are:

700.1hp and 646.8hp uncorrected @ 77* dyno temp and 2700ft elevation
