BD II's or DD II's

[KennyM]

That would be my plan. As long as I can have smoke control, I will be happy

DD2's

I love my DD2's. My EZ is on level 3 and I have miniscule smoke when I hammer it with low boost. I think being at sea level helps.



I've been told that Lawrence at DD says the 2's actually smoke less than the stage 1's. You could check that out.....

 

[MUDDY]

decided

made up my mind to go with dd2s. considered 3s but i tow and dont want to worry about egt. also looking at the dd chart trq is lower at low rpm with the dd3s. i want gobs of low rpm trq.

shopped around a bit and talked to blake at speedzone performance and he gave me a smokin deal. http://www.speedzoneperf.com/



gotem in, and WOW .

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

I have DD2s and with the Comp off there is no black smoke a little gray haze at WOT. With the Comp on level 2 I can get a small puff of smoke. On level 3 I can smoke real good and I have not been on level 4 or 5, still waiting on my clutch. Get yourself DD2s and the Comp box and all you will see in the mirror is . Sam

Jim,



The one thing that you will find with Lawrence is that he is like my father in his ofter harsh answer. Not always politically correct but by the same token he will not lie even if it costs him a sale. I no that lawrences responce may not be what you were looking for but it was probably true.



I'm not going to try and act like an expert on building injectors, but I can tell you one thing Lawrence can build power. I would say that he is probably the best in the industry at what he does. Suprisingly he is also very modest in the power that he premotes. I went to DD on Tuesday and went for another drive in his P-Pumped truck and even turned down to 370hp it was amazing.



I for one totally agree with Lawrence on being very selective on who the Super Mental injectors go to as they are more than most can imagine. But for the record I would have to say that once you get past stage 3's that the extra fuel become useless for drag racing, as the trucks produces a lot of smoke but the lag goes up because there is just to much fuel.



But for those who are looking for the most power period and know what they are getting into, I would have to say that my Mentals would probably be #1.

 

[Joseph Donnelly]

Lawrence has a lot of experience making more power with injectors. He knows how to maximize power without excessive smoke. He has also investigated size vs. power and there is such a thing as too big. He is a master at maintaining excellent fuel atomization while making the injector "bigger. " You can get to the point where a bigger injector makes more smoke but little if any more power. That is not just a function of how much fuel is sprayed, it is also a matter of the quality of atomization. It is tempting to see a Ram that bellows clouds of smoke doing a sled pull, etc. and to assume it makes "hundreds" of horsepower more than another. Might not be true at all, might be other factors like tires or suspension, or just be driving ability.

i figured it was true what he said. but instead of telling me that bullydog beat him to the punch on the 5's, he bad mouthed his rival's. i've talked to enough people that have the 4's to know that they give at least 120rwhp and dd's website says the supermentals give 125rwhp. so if bullydog says the 5's will give 200rwhp i'm going to give them a try. but for lawerence to say that his 3's are the same as there 5's is a flat out lie!! and that's bad business imo. if the 5's don't do what they say they will, i will be coming up to visit you and have you install the super mentals.

i know he can build power thats why i called him and wanted a step above super mentals.

i guess i feel that it's my problem if i blow up my truck. as far as the lag for drag racing you can either go with twins or use no2.

will you and your dad be at tulare? if so i will look farward to meeting you down there. your dad is a good guy!! he even let me drive his truck in spokane, if i had an auto it would have your stuff in it. i will let you take my truck for a spin with the 5's. they should be here monday. what a way to break them in buy driving 2400 miles.

DD2's are in....

And I am dissapointed. SOP tells me they haven't made much difference over just the EZ. Slightly larger smoke plume before spool up. Seems clear after spool up. The power is not at all what I was expecting.



We also had a dyno event yesterday and it dynoed only 250 HP/540 TQ. Similar truck, little less weight and same mods dynoed 300 HP.



This seems awful low for what I have. Granted it's a stock transmission (Soon to be DTT)



Gained 1# of boost to 31. WOT fuel pressure momentarily drops to 5 PSI and then recovers to 6-7. 14 PSI at idle. After reading threads on fuel pressure I think that I'm OK with that.



Any ideas? Followed DD's instructions to the tee. Anyone have problems with the HY turbo not giving them enough air for this amount of fuel??



Waiting to see on the mileage as I had my foot into it too much to tell.



Garrett

 

[MikeR]

Garrett,

First thing,that HY turbo is way too small to move enough air to match the fuel you now have. Second,your sock automatic isn't going to transfer your new added power. Everything has to match as a system to make a desired power level.



-Mike

 

[CCahill]

Gotta agree with Mike..... Not only is your TC way ineffiecent. . something less than 80 %, but you won't get lockup on a dyno. . even with DTT's goodies... Only if you have a Smart Controller, or some other lockup method. . You could add an easy 20 % with Bill K's parts, and even more if you can get the thing to lockup... Plus your dyno guy needs to figure your effective gear ratio when you dyno your truck. . and tire size will effect the ratio...





as far as SOP, I felt quit a a difference with my #2 injectors. . And I also have the HY. .

Jim,



It's good to see that you know what you are getting into (a chance of taking out an engine). Advertised #'s are great, but I would honestly be stuned if you gain 200rwhp. After running the mentals I know that EGT's become virtually unmanageable and the smoke become rediculous. Don't get me wrong I have ran Bullydog injectors and I can tell you that there 2's diffinately deliver what they claim. I just find it hard to believe that you can get 200rwhp with injectors that are useable. I can tell you that with the Supermentals there is greater lag than the DD2's, therefore I can't imagine what it would be if you had more bottom end fuel.



About Tulare, I won't be there but my Mom and Dad will. They will actually be in our Ford running the new TC. But I will be in Washington in November if you are close we can go for a spin. I think that we would have a tight race even if you used the drug. It would be fun to see how they compare.

Well, I think I'll add my . 02. I have had BDIII's for almost a year now. They add about 105 HP. Almost exactly what DD claims on their DDIII's. With the PE Comp off, I can't see any smoke. Smoke is applied as the Comp is turn up. I usually run in level 3x1 setting of the Comp. This setting produces very little smoke but great power. However, I'll have to admit, there are times when I get the urge and go 5x5! When this happen, people behind me at times have actually stop! I think they think that my truck just blew up.



MikeR,

You will have to tell us about your first hand experience with black smoke and accidents. We are waiting to here them!



And I don't know if my BDIII's smoke any more than your DDII's!



Stefan,



Even if Jim has more HP in his truck than you, he will have an extremely hard time beating an DTT Automatic! Shifting just take too much time.



IMO most people will be happy with either brand of injectors.



Just my . 02.

POINT OF CORRECTION HERE:



The DTT Smart Controller will NOT allow the TCC to lockup during a dyno run as their TC Saver technology is integrated into the Smart Controller as well (as well as other proprietary software and hardware controlling the transmission). Additionally, with "just" a DTT TC an VB you will not be able to achieve TCC lockup when running on a Dynojet dyno.





PS: if you want to use a BD TorqLoc to manually lockup the TCC during a dyno run (especially with a Cummins TD producing high HP and torque)... be my guest!



..... just forward the contents of your bank account to your choice of transmission rebuilders.

with my 6 speed it would be tough for me to out run ya at the track. but i would be happy to do a roll on at about 50. i won't even use drugs. at may madness bullydog had there 5's in there truck that made 643rwhp? bullydog does not recommend these injectors for the street. " what do they know. "as far as 200rwhp that's what they said. i'm hoping for at least a 60rwhp gain over my 2's. i've heard that they flow 65% more fuel than the 2's. hopefully i can crowd the 500 mark with no drugs.



i look forward to bs'ing with your mom and dad again. did he ever fix his custom dash insert?



jim

 

[Joseph Donnelly]

With either 12 or 24 valve Rams, you will not feel the added power over a certain point, because the torque converter slips too much. Once locked up, if transmission line pressure is sufficient, you will feel the added power.



With the 24 valve, unless you have a box to cheat the boost signal, the engine defuels if boost gets over 20. 5 psi. Thus, extra power will not be felt until that problem is addressed.



I believe Diesel Dynamics claims about hp increases, as they dyno the stuff before and after, not just during product development, but also for many customers who have the stuff installed at their shop. They also know how much hp can and cannot be gotten from modifying injectors by different techniques. They are not "holding back" power increases for any reason. If the injectors can give the power with good driveability and perform reliably over time, they offer them.

GKR, did you see Bill's carpentry work?



BTW Joe (Donnelly), I have absolutely NO power transfer problems with my DTT 93% TC... with only a 7% reduction of power transfer from full TCC lockup (while in fluid coupling), most anyone would have to admit that's as good as it gets for us auto. guys. This is the TC of choice by Lawrence Bolton of Diesel Dynamics in his test Ram. Why? Simply, because there is none better!
