Anyone with .007 B-Codes

RockinJW · May 8, 2007

My truck is currently at Wide Open Performance getting the beefed up parts installed /ubbthreads/images/graemlins/cool.gif

I'm now getting serious about my injector decisions. Money is restricting me to continue running my replacement TN turbo for the time being, so my tunes will have to be pretty conservative to keep me around 35lbs. of boost.

But what I'm wondering is, when I have enough turbo to support the injectors how much power can I expect out of .007 nozzles?

This truck is my daily driver, I tow quite often, and streeability is important. I've posted about this before but never got any real clear cut answers. I will be purchasing Dynomite Diesel injectors I just don't know which nozzles to get with them. 007 or 0075 /ubbthreads/images/graemlins/confused.gif

Can anyone with first hand experience with either nozzle give me any insight? What kind of power are you making? What about egt's?

I have a set of BD codes with .0075 nozzles and was running a TN replacement, which I roasted due to some other apparent problem- I'd overspooled it months before on a down shift and probably galled the bushings. The TN plus a 120 hp Jody tuning doesn't have a prayer of cleaning up, and there is no way you will be able to tow 100 yards on a hill in that setting. It will get WAY too hot. Personally, if I were to do it over again, I'd get .0070 EH holes put in at Dynomite BECAUSE I TOW. Yeah, you'll make a little less power, but I think you'll have a better overall setup. You will have plenty of power for towing and getting yourself in trouble. Your atomization will be better with .0070 anyway, and I think that will make it more streetable especially around town. Mine smoked too much even at 40 hp settings and I was constantly concerned that I was going to get nailed by the air pollution cops or cause an asthma attack. The beauty of single shots is you can tune them down and you will get better mileage while you are waiting on more turbocharging.

Jody has his "negative" hp programs, like a -20hp setting, that seem to work well... when I was following behind Joey in his 95 down to Tulare, the smoke was pretty non-existent. Just a little heat signature and the slightest puff of black on slight crests along the highway. His turbo is a big bigger than yours, though, and not sure what nozzles. Maybe he'll chime in.

But from a "other vehicles on the street" vantage point, it was fine. /ubbthreads/images/graemlins/grin.gif

LMAO, I can just imagine that one. Having to push an expensive motor. So would the question then be whether to get big injectors or an " upgraded " turbo that can handle the load if both couldn't be purchased at the same time? /ubbthreads/images/graemlins/shrug.gif

I'd say it's a coin toss, but the ultimate goal would be to have them matched. Tuning is pretty forgiving by backing down the pulse width until it's drivable, but exactly what the atomization is going to look like on .0075 injectors remains to be photo micrographed. I suspect that they are pretty sloppy at low HPOP pressures.

Extruded Honing really does smooth out the holes so they allow a lot more fuel flow compared to wire EDM holes. I believe that has been documented. That's one big reason why I personally favor the idea of .0070 nozzles for the original poster.

The guy is spending some serious coin for engine upgrades and injectors. He is concerned about budget and said so. We all know that turbos aren't cheap when you are already spending a small fortune. Kinda hard to justify spending that much at once, or even saving up that much to blow on an engine (for most of us). Based on that, I suspect that the present turbo might just spend another year on his truck, maybe more. That's just speculation, but if I'm right, the .0070 tips would be a much better choice, at least for now.

I couldn't even begin to utilize what my BD codes were capable of. When the TN seized, I had to put the stock turbo on due to logistical problems at the time. Talk about a setup that sucked...like a VW carburetor on a small block chebby.

The plan is to have the injectors installed sometime in August and turbo/turbos this upcoming spring. So the TN replacement will have to do for a while. Thanks for the input Clam, that helps me out a bunch.

I need some testing on the new ceramic ball bearing drop in unit. Let me know if you are interested in testing one-with a 1.15 non-waste gated housing for your B codes.

JW, I currently have .0075's in my '01, and with the gtp38r and a 1.15 nwg housing it was a towing machine. Spoolup was fast, little smoke in the low position on the chip. I pulled a big gooseneck horse trailer a lot and it performed well. On top end though I had a wee bit too much smoke and almost broke the needle off of a 35lb boost gauge. If you don't plan to race the truck get the .007's, also try some different tuners - some of the best programs I used were from David Lott and Tony Wildman.

RockinJW · May 8, 2007

Sniper- what are your egt's like when towing? Stock intercooler? Any idea what kind of horsepower your making with that set-up?

I would really like to be able to get into the 12's and 500hp, once I get the right turbo on there of course, think that's possible with the .007's?

Either way, from what you guys are saying it sounds like the .007 is the best fit for my driving style. I guess I could always throw a little water/meth into the mix... /ubbthreads/images/graemlins/confused.gif

NO! Drugs are bad. Remember the pic I showed you of my block?

Tapercore Any idea what kind of horsepower your making with that set-up? This truck was at 471 with hybrids and stock oil, if I had to guess I would say right at 510

 nope, but if you tweak the heck out of it you might get real close

I didn't think meth was a good idea, but I may need the water for the cooling...
