The injectors Blake is talking about I actually knew nothing of the failure until he sent me a link. I built those injectors myself with the customer standing next to me watching. The injectors worked flawlessly for nearly two years. That type of injector failure has happened alot. (injector tip cracking) It happens with stock injectors alike. We just put a piston and two new valves in a engine last week from this. It was a stock injector truck. Half the nozzle came apart. Actually split down the middle.
Keep in mind, we sold over 300 sets of injectors last year. We are approaching 400 this year, that is over 3,000 injectors. When you are talking that number you will have failures. Its inevitable. It does not come down to assembly issues or quality. It just happens.
Blake was quoted saying "Of course, y'all may have improved your injector design since then"
For the record..
All of us use the same vendor for the new EDM`d oversize nozzles.
Casserly
Industrial Injection
Elite
Hypermax
Innovative (when he installs larger nozzles)
The list can go on and on..
Anytime you elevate injection pressures you risk this. So, that being said anyone running a SCT from a tuner who uses the SCT advantage software values will have this. That is because the transfer function of the ICP tables lies to the PCM. This causes highly elevated injection pressures and eventual failures. The tips are rated for 24-26K psi. With these values it can approach and exceed 30K PSI! Add the brittleness of a hardened material and pressure spikes and BOOM you have a broken tip.
But again, needless to say there will always be failures. The guy who sells the most parts will get the brunt of the bashing. Its the law of averages. I feel we make one of the best parts on the market. This goes unsaid when Eric from innovative runs our parts on his truck, Craig from MPD runs our injectors. I actually sold Craig injectors back in 2006-07 for his first build. Matt from Spartan Diesel uses ours in his 6.0. Even Shawn Ellerton is switching to us. Results and numbers is what counts and we will continue to offer only the best product. We now build new plungers and barrels in stock sizes and the hybrid version (race only)
We used to reuse borderline parts to try to keep costs down for customers but we have stopped that practice. Even if the customer is upset because he cant understand why we want to replace a questionable plunger and barrel or any part for that manner. At the end of the day he is happy because his valve covers will stay on for a long time with no issues.
The Hartridge flow bench has been invaluable, it has let us fine tune the nozzle sizing. Offering the best atomization in the spray chamber, along with lower EGT`s, better mileage and top notch performance when the hammer is down. I am sure all the vendors using the nozzles have seen a plethora of sizes come available. This is because we order them in huge quantity's built to our specifications. Those parts would have never hit the market without our R&D time. We also share this information with Eric and other tuners to help them fine tune the vehicles based on our flow rates at said injection pulse width. I personally have came a long way custom tuning these trucks in the last year with the addition of the flow bench. We can now work of calculations as opposed to guesses.
But anyhow, there will always be people who have personal preference. Thats why we share information. The end goal is to keep the HEUI injected truck in the same ballpark as the common rail engines. Its hard for me to come on here and get bashed by people who have never used our product. They have no idea the hours that have went into delivering the best product we have available. Hell, at Scheid a customer put down 610rwhp with one of our 68mm powermaxes and 205`s. I think thats great news for the 6.0 guys. A truck you can drive, tow and still mop a hot tuned Dmax or 6.4 for that matter. That just goes to show, when you build the turbo, the injectors and tune the truck all in house you hold all pieces of the puzzle and can be assured they will fall together for the end user.
That being said, with this new start I hope you guys understand where I am coming from. We are all here to keep the 6.0 competitive.
Thanks!
