One obvious point: the Bully Dog injectors smoke way more than the DD's do. If you add some kind of powerbox to your rig,then you'll be blinding other drivers behind you when you pour on the fuel. Imagine what your trailer is going to look like too.

ALL the big injectors smoke with low boost and heavy throttle. If that bother's you, don't go beyond stage 1. I remeber when WIZ (another TDR member that hasn't posted here recently) put the DD supermental injectors on his ETH, said it smoked like a freight train in the summer heat and humidity. Not that mine don't, but since the humidity is lower and the temp. s are cooler, a low smoke start is possible with light acceleration. It all depends on how you drive, nail it with low boost and yes, there will be copious amounts of smoke. Shift through the gears at the higher rpm's and smoke will not be a concern for you or the other drivers on the road. Bottom line is to pick whichever you feel comfortable with, DD and BullyDog both make good injectors IMHO.

Guys don't get me wrong,I like power and smoke very much,and yes mine does smoke alot. It smokes during normal driving upshifts (mine's definitely one of the smokiest among the NW BOMBers). But I'm mearly giving baby BOMBers some fore-warning that when you add a box to big injectors you will smoke very thick,and that the Bully injectors smoke thicker than the DD with a box on.

I'm mearly giving the warning because I have first hand experience in the resulting thick black smoke almost causing accidents by my screwing around. That's why I leave my box turned off now.



Bigsaint,

I'm only curious,but what are your EGT's like with the step 5's during highway driving? A particular truck up here with the supermental injectors burns a steady 950 deg while driving unloaded on the highway. I would love to test,dyno and race a set of step 5's or supermentals in my rig.

i agree with mike , i have DD3's ( thanks bill ) and can attest to that fact that when my HOT PE is on level 2 or hot level 3 that drivers behind me change lanes due to the blinding effect it has , and this is hitting 40psi of boost .



i get very little smoke with the box off , the DD3's are more than enough HP for everyday hot rodding , my PE is a drag race piece now , though i do exercise it once in a while ... .

Mike,

Kinda curious..... did you do back to back tests with DD and BD injectors, on the same truck, same day, to determine which one smoked more... or is this something somebody just told you... . Like I say... Kinda curious

 

[MikeR]

Collin,

No I didn't install both on one truck,but with our big group,every known combination is here and I've witnessed it. Although a very respected shop in Abbotsford has tested and came up with the same observations I have. I'm not bad mouthing any brand. They both make the power that the manufacturers advertise,I'm just reporting an observation.



Tell you what,to any manufacturer or vendor that can read this. I'll spend an entire day with my tools and my own money for a dyno block out and test different levels and brands of injectors if they loan me the injectors for testing (I'll give them right back).

It would be nice to see every brand and level of injector tested on the same truck.

 

[Bob Wagner]

And I volunteer to be Mike's sidekick for the test.



Mike I will do a some research on this



But I am serious about the testing



I May have access to a dyno in Federal Way

 

[Fred Swanson]

Did you take into account a new clutch while you're at it?

 

[SlyBones]

They should donate the injectors for the test, so Mike can sell the used injectors to get money for the new clucth.

 

[Bob Wagner]

Hey Southbend clutch in use here

It will hold the power



And I am sure Peter would be willing to help out

 

[Bigsaint]

MikeR, just re-read my post and if you got the impression that was taking a shot at you I apologize, didn't mean it to come out the way it did, just talking smoke in general.



As far as egt's go, mine are low. I maybe gained another 50 degrees pre-turbo. I don't drive highway miles much, but a steady 55-60 on the flat will see about 550-600, depending on the outside air temp. of course. My town is full of hills, either I'm climbing one or going down one. Normal driving in 4th or 5th gear shows around 800 degrees while climbing. We have a pretty good size hill in town, 17% grade for about 1/2 mile then it goes to about 8% for another mile or so. Screaming up the hill full out with the EZ and the injectors will show around 1200 degrees pre-turbo.



As I stated before, since the addition of the 5's, I very seldom move the TST from the 0 setting, there's just no need. Once a week, I'll bump it up to level 2 and sometimes level 6, beyond that the box is just too radical for me. I hate the way it shutters when you let off the go pedal in levels 7-9, can't be good for the life expectancy of the VP44 IMHO.



As for the heavy fueling boxes and the Bully's, I have to agree. I have never witnessed DD injectors and a box, but the Bully's smoke like a coal train no matter the weather when you get it with low boost, much more so than with just the EZ box.



Guess we all have our own tolerance for smoke, maybe I'm a bit hardened from running the BD 3's for a while, but I think the 5's are fine for the street with the EZ, nice power combo for the ETH and the smoke isn't bad in my book.



One thing I would like to add is the smoke( read soot) and keeping your truck clean. Whe I first put the 5's in, I still had the BD 4" exhaust, exiting behind the rear wheel with a Geno's 5" monster tip. A short 10 mile trip would turn my rear quarter panel grey . I swaped it out to the stack, now I get the 'soot shower', which isn't bad on dry days as it just blows off once you start moving. Forget about if the truck is wet from rain or morning condensation, the soot sticks to the truck like glue until the next washing .

Fred,

No clutch problems here. Since the beginning of the year I've had the original 450hp+ Southbend ceramic Sachs clutch installed.



Bigsaint,

I'm impressed that they run that cool. You know... last I saw,Wiz was on the Ford Diesel site crying about how his truck was unreliable and always breaking,and that he was going back to a PSD.

I'm with you on the fueling box. It's pretty violent when jumping off the throttle between gears with it set at 7-9.

 

[CCahill]

Mike,

That seems to be the most accurate way to truly test any of the injectors, fueling boxs, air filter setups... I've seen dyno results from what seems like the "same" truck with different results..... ETH, ETC, whatever... . The baselines for some of these trucks, are all over the place... This too, is just an observation...



Colin

 

[South Bend Clutch]

I know that running a bunch of dyno runs can be hard on a clutch. So, for the purpose of R&D, if Mike happens to toast my clutch I will be more then happy to donate a clutch for the cause!



You guys are great. Keep up the good work.



Peter



P. S. Mike, even if you feel as though you might have hurt the clutch I will replace it. In my few conversations with you, you come across extremely professional and have earned my respect.

 

[CCahill]

GEEEEEEEEZZZZZZZZZZZ!!!

Peter, that is way generous...



I live on the left coast, somewhere south of Mike... If I could get Bill K. to "Donate", I would be moren' happy to put my truck on the rollers for a day or 2.....



I'll run it 'till it pukes!!!!!!!!

Well, I also took my time and talked/emailed lots of folks before making each of my BOMB decisions, as I wanted to do it right the first time, regardless of the cost of each BOMB. I ended up going with the DD 3's largely because at that time HVAC also had them and highly recommended them. I would have gone with the Super Mentals but they were just not quite on the market then.



Chris Sutton [csutton7] had the DD 3's in his 99 Cummins until about 3 weeks ago, now he has the Bully Dog 5's. I asked him last weekend at a truck pull what he felt the differences were, and he said he hadn't had them in long enough to get a real feel for any major differences yet. Shoot him an email or Private Message to ask his opinions, since he has used both brands.

[SlyBones]

Looks like it time for those injector vendors to step up to the plate. Peter, having a DTT auto trans I am not at all disappointed, but if I had a manual YOU would be getting my money!

 

[Bob Wagner]

Right now I am sitting on the fence trying to decide which injectors to purchase and I know several others members

that are ready to go too.



I hope the pieces fall in place for this testing

 

[KennyM]

I started this thread with a simple question. What I got was an education. Now I am worried about to much SMOKE. I plan on increasing my vacation towing to about 4000 miles a year. But, I also want to have some fun when not towing (eating Chebbies and Phords). With everything I have read I plan on going with

DD I's. I plan on having a comp box also. If you think I can get away with DD II's and not turn my trailer black, give me your opinion.



Thanks



Ken

 

[Mopar-muscle]

ken , how you use your comp box will decide on how black your trailer gets .



i'd go with DD2's , leave the comp on level 1 with the fueling on level 1 or 2 , this should also be easy on your clutch wit hthe trailer in tow , when the traileris off , go 5 by 5
