Engine/Transmission (1994 - 1998) Injectors have you seen these?? Big MPG increase claim.

[WPeschel]

Has anyone tired these?? I was thinking of going with Dynomite diesel 90's then I saw these... He claims mpg gain... Just keeping my options open...

never heard of them, and I couldn't get past the first few sentances of the ALL CAPS without getting dizzy



I've had great luck w/ DDP injectors in my 12v trucks. *I* think you should get the DDP4's

DDP 4 are 140hp injectors. . You dont think they would be toooo hot for towing?? Remember I do tow pretty heavy... I talked with Ross about a week ago and he told me that the stage threes might be a little toasty for towing he said to definately use a aftermarket turbo.....

 

[WPeschel]

These injectors will give you 140+ horsepower at the wheels. They have been used to make over 650hp on fuel. A 66mm inducer single turbo is the smallest turbo we recommend for these injectors. Please, please, please realize that these are big injectors. We at DDP know that these are not the cheapest injectors out there. Spend your hard earned money one time and get the best. These injectors do not haze at idle, smoke less than 370s, get better mileage and have lower EGT. 370s are a cheap way to make some power but the negative charectaristics get old real fast!



This is off of their website. . 140hp sticks. .

 

[biggy238]

I grossed 23K with mine and the fuel plate just a tad below stock setting. This is on a stock turbo.

 

[Moparsean]

I'm the 2nd guy in the ad that bought a set,the claim was true for me. I love them,i was told they were comparable to the "370" hp injectors. I had 330 marine ones that gave great power,but smoked heavy and my mileage was horrible. they missed too at times. I feel the ones off e-bay were well worth the money and he was awesome to deal with after the sale too. I know e-bay can be scary at times,but i'm still running these and i pull some heavy loads up BIG hills here in NH. I still get 20 mpg at 65 mph and about 18 at 75-78 mph.

 

[Forrest Nearing]

I ran DDP4's with a 62mm turbo and loved them. great mileage, awesome power.



but I would get the DDP3's before I bought the ebay no-name jobs

 

[Vaughn MacKenzie]

Their price is about the same as the smaller DDP injectors, but they do come with washers & a brush to clean injector bores according to the ad. I'm with Forrest on the ALL CAPS, I usually run from anything sold on eBay advertised with the CAPS LOCK ON.

Another thing that jumped out, they used to build for Bullydog. . . back in the day (around 2000-2002) Bullydog's 24V injectors tended to be smokier and hotter than Diesel Dynamics for the same HP injector. Don't know who built those injectors though, if it was these guys or someone else.

I think given the price I'd rather spend a few more $$ and go with DDP.

Wow, there is alot of info in that E-Bay post, maybe I should retype it in the correct format, no caps except were there needed get rid of the run on sentences and typed in Courier New and bullet format... ..... na what a waist of time.



If something like this came across my desk I would loose my mind.



I don't think I would try 3's or 4's without some air... ... . not a small injector.

I plan on following up with a 62/14 turbo shortly after injectors... Hell I might buy one before not sure yet...

A quality Injector

I had a set of these Red Oak injectors installed a couple months back. We checked timing before with a timing light and had 16. 8 at the injector (I have mine bumped a little). Installed injectors and reshot timing getting 17. 9 with the new Red Oaks. My old original injectors pop tested around 3200. The new Red Oaks were 3300. I think the lower pop pressure is adding the timing. We just happend to be sitting on a dyno and did a before and after run. Just the addition of these injectors in my setup added another 31hp pushing my setup just over 400. We did a run just before installing the injectors for baseline.



I was drawn to these inejctors for the mpg claims. I really did not want any more power. I talked to Stan at Red Oak a couple times (712) 623-2221. He stressed the fuel savings and smoke cleanup over power. He said these injectors were the same as a 215 nozzle as far as # holes and spray angle just larger diameter holes. The tips are Bosch factory new... untouched.



My engine ran pretty smooth with the old injectors but these new injectors made it ever smoother.



I have not ran enough fuel through to commnet on economy improvements but the cold white smoke is almost non-exixtent. It is also much harder to make black smoke.



Time will tell on these.

You are 100% correct about wasting your time doing that. I can say so with authority because I did that myself several months ago when I was considering a set of his injectors. I tried printing a hard copy of his ad to see if that helped. It didn't. It still gave me a headache trying to read it.



I contacted him, via both ebay and telephone to get some questions answered and was very interested in his injectors. He was very responsive and seemed like a decent guy, too. I also posted here asking if anyone had tried them, but got no response.



I actually DID take the time to retype his ad and put in some paragraphs so my eyes would quit crossing and I could come up for air now and then.



I sent him a copy of his ad done my way and a message explaining why it needed to be done and asked him to compare the two and see for himself which was easier to read. I was very polite and told him he was welcome to the revision I sent him. No change in content, just MUCH more readable.



I also had a couple more questions for him about buying his injectors.



I never heard back from him after that, so I think I ticked him off by suggesting his ad was "lacking" in readability and turning people off...



Guess I was right judging from the comments here from the very people he should want to read that ad...



I would still like to try his injectors, though.

 

[Moparsean]

Try them you will like them,you don't need to blow smoke to make good power. These injectors will prove that to you over the "other ones out there" With fuel at 4 bucks a gallon,mileage should be on everyone's minds i would think. They worked fantastic for me. The ad is hard to read though I will agree there.

 

[JacobsD]

I like how in the Ebay ad he mentions that some places are selling injectors that claim to gain 70-90hp for $200.



Wow that wasn't a shot at Pensacola Diesel.



I have those Pensacola Diesel injectors and have the dyno sheet to prove the 80hp gain over my previous setup, and happen to really like those injectors.



Just my couple sentience rant... #@$%! :-laf

 

[Jim Fulmer]

Sounds good, BOTW a 215 injector is a 145 degree spray pattern, it matches your pistons.

[CTD12V]

I understand how extrude honing, like DDP does, improves efficiency and results in better power and economy, but what does Red Oak, a. k. a. "thedieseldude", do? Factory tips, barely any increase in pop pressure from a 215 . . . How are they increasing their efficiency???



I'm glad this thread started! I too have been wondering over whether to get DDP 50hp injectors or these. My main concern is mileage improvement.



CTD12V

 

[JJW_ND]

What I know....

I believe a new bosch 215 injector pops at 3800. Mine had dropped to 3200 with the 300K miles I had on them. We checked the timing with a timing light before and after. I was suspect of the earlier timing readings so we dropped a valve to index exact TDC. Even though the difference between the factory old injectors and the new Red Oaks was only 100, it still increased the timing just over a full degree. If the factory injectors had been a little fresher, the timing increase would have been even more. If one adds these injectors to a truck that has had no timing increase, the 1 - 2 or more degrees of timing increase that is added with the injectors alone will most definetely increase mpg.



Stan said the tips are new factory Bosch tips that were never sold/designed for a automotive application. The tips have the same number of holes as a 215, same spray angle, just larger holes.

I get 18. 5 mpg now on the interstate 75mph empty with a heavy flatbed. I just dont know if I coud bump to 20. 5 mpg with just an injector change. IF I did get this increase, I need to figure how many miles it would take to make up the cost of the injectors

Wish I got that good. With diesel very likely headed for $5. 00/gal this summer, I guess it won't take that many miles to pay off a new set of injectors. Not sure if that's a #@$%! or a .





Thanks for the additional info, JJW_ND. Do you think the mileage increase comes more from the timing advance than from a better spray? My truck is at 15. 5 right now, so maybe I would not see that much of a mileage increase.



Is anybody running these on an otherwise stock (or close to stock) engine?



WPenschel, did you go with the DDPs?



CTD12V

 

[JJW_ND]

Both...

Those of us changing injectors to get mpg improvements are probably doing it when our current injectors have over 200K miles. At that point any new clean burning economy injector should add at least 1 mpg over the tired originals. The added timing with these Red Oaks should add at least another 1 mpg. If you have done power enhancements and can make lots black smoke, you should notice a significant reduction in the amount of black smoke. With tired injectors, you might have a blue haze while the engine warms or even after it is warm. This should all clean up.



Cal Stan at Red Oak if you want more info. He is a knowledgable guy. They run a top notched Bosch certified shop doing injectors for all equipment for a living.



If you do not have a 215 pump engine, putting in new Bosch 215 will get you a great clean buring injector. I would expect (from what I have read) the smaller DDP injectors are a great economy injector also.
