Again, thanks to Dmaxallitech for doing the install while I played on the dyno testing other trucks. I haven't driven the truck much yet, but can say for sure that the gains are solid across the board until we hit the ceiling and start really overfueling. Smoke seems minimal without programming, but put a big box on and watch out as it's gonna roll! Here is the end result as compared to the stock baseline:

So where are the killer sheets w/ the stacks and nitrious?


How much does this cost to do on a LB7 and LLY?

Here's the before/after on the VA 200+ using the low setting:

Please note that the notes on the bottom are carry over from the Superflow program. I've been very lax about changing them while testing and have been using my paper notes then renaming after the fact. The 200+ on low setting is a scaled down program designed to be more driveable, although the 200+ is quite well mannered also.





The spread diminishes as we hit the next level, and I have not yet run the nitrous. Haven't even purchased the parts yet... Edited by: Kennedy

I believe John has the injectors up for 1200.00 and that does not include a core. I believe going to just nozzles will be the way to do it so you dont have to worry about ending up with sub par cores. Quality cores are hard to find and expensive. Figure 2200 for the injector work and install.

Basically, I'd rather do YOUR cores. There is just too much risk accepting someone else's cores on an exchange basis.





If a guy does not require test data, the nozzles themselves can be reworked for less $$$, BUT I still recommend having them assembled and fully tested. The results will not be absolutely perfect, but they will be fairly close when properly built. They are best done in batches so they can be matched as closely as possible...

Very nice, thanks for all of the hard work and testing!http://www.dieselplace.com/forum/smileys/Clap.gif


Would these injectors give a smoother running engine due to the closer grouping? Would they increase fuel economy any?

I need to run them some more. They are definitely smoother than the originals ever were. Dunno when I'll actually get a decnt MPG run though...

So what are the new dyno numbers in your sig with, the new va and the injects??

Yup,





Things happen pretty fast during a burnout, and the trans has trouble shifting quick enough so it sometimes "bobbles" at the limiter, but I believe it now burns my 265's through 4th gear and into 5th where it gets a bit ahead of itself, the turbo sneezes, and it motors away....

I was there when John ran his truck. I commented to John that I thought his trucked idled quieter than my truck. The updated injectors are impressive. Excellent numbers over stock for sure.

I understand that the spread would be less with the high setting on the VA200, but what was the spread anyway. The NOS people would still be able to use them together even if it doesn't show much gain without the NOS.

The upswing does not gain as it is too overfueled like many other programs, but once the turbo gets singing, it has some decent gains. There is a lot to be gained with more air down low, and the curve up top is still without rival.

Add a turbo and or some nos and you'd change your sig. to 700+. http://www.dieselplace.com/forum/smileys/Big Smile.gif

I won't if you won't http://www.dieselplace.com/forum/smileys/Clown.gif When can i let the cat out http://www.dieselplace.com/forum/smileys/Ermm.gif


Nice gains with the injectors. How bad does it smoke with a big box on????? What does your dyno read up to for trq???? Went to dyno again today and this not reading over 1200 is not the handiest.http://www.dieselplace.com/forum/smileys/Clown.gif

1400HP and 200mph are the only ratings I've seen. Doubt we'll maxout the TQ...

I'd have to say not............don't think you'll have to worry about the hp either, at least for a diesel. http://www.dieselplace.com/forum/smileys/Confused.gif

Translation: How come I ain't got a set of those yet!! Throw a set on my tab! http://www.dieselplace.com/forum/smileys/HiHi.gif

Good to see that nozzles will work! http://www.dieselplace.com/forum/smileys/Clap.gif I know there were some nay-sayers.Edited by: KERMA

I have, and will have nozzle assys available, BUT it is my position that they should be installed ANDoperated on a test machine prior to installation.


I'm anxious to see hoew the enlarged hole units do. The units that I am running now do mot have a significant hole size change which I believe to be a big plus for atomization.

It doesn't take much bigger holes for significant gains when you're talking common rail injection pressures.


The high injection pressure makes proper assy and testing all the more critical. We all know about the "fuel-in-oil" issues and such...

What % over did you go JK? I dont think bigger ones smoke as bad as you may think when running only them, now add a big box and the smoke pours!

those were 20's.


We need to do a set up of 10's, 30's, 40's etc... then put them in and run them on the rollers. I wonder if they make quick connects for valve covers?

If Jk has 20% and I know a guy that has 40%http://www.dieselplace.com/forum/smileys/Embarrased.gif and I know another guy that has 60%, sounds like we all need to dyno together. One thing in common on all of them, Dmaxallitech installed all of them!

We dont have a baseline from you two, but we can get somewhat of an idea anyways...

The guy folllowing me tonight (Dmaxer) pretty near got lost in the cloud with the bix box on top! He just about needed to change lanes...


150HP box on top isn't too shabby either...

Not a bad idea, BUT there's one key issue here: NO STACKS! I'm not planning to put together an elaborate exhaust extraction system. Not planning to dyno semis, so a guy will need a rear exiting exhaust system. I'd like to keep the walls/ceiling white...

Oh come on JK, I was thinkin about puttin in some stacks for the summer. I have the stacks and my tubing, just need to put it together. You could call Cozzilinos in Indianapolis and ask them if soot comes off the ceiling as their celing is about 10ft tall over the dyno, nice and black after a truck with stacks was done.

White Duramax


Where in Indianapolis is Cozzilinos?





Greg

Cozzilino Motorsports, they are on the southwest side of town. Kind of directly south of the airport. You take Kentucky Ave. west off of 465 on the west side and I cant remember the rest but its only about mile off of Kentucky ave then. Are you going to dyno??
