extrude hone

[Archive]

Wouldn't it be great if we could find someone to extrude hone stock injectors to what level we want. That way we have the stock part #. Someone said DD would EH the RV injectors for $160. I asked them to EH my stockers and they said NO! I'd rather pay $160 to EH my stockers than the price for new EH ones. Thats probally why they won't do it. They make to much $ the current way.

Mike, the Diesel Dynamics "A" (automatic) series injectors are Bosch products. You aren't going to have any trouble with your warranty running 275 Bosch products, they can't tell that they are extrude honed.

DD II's and III's are now available with the stock part number. DD calls them stealth injectors. According to their web site, this adds $100 to the price of the injectors.

Stealth? Who we trying to kid here guys?
I know alot of techs are no help and most are little 'green' at the diesel thing,but they're not stupid. If your truck is in for a driveability concern,all they have to do is take it for a test drive and realize your truck ain't stock. As far as the part#'s go... who cares what number is in there. The injectors are buried in the head and you can't see the numbers unless you take them out. No tech is going to just take them out to check part#'s.
I guess you just have to be careful what you take your truck in for.

Mike... good response. I feel the same way. The part I don't understand is why DD or some other entity won't extrude hone injectors that we provide to save us some cash! They certainly know what a set of injectors cost them... just deduct that price.

go to www.extrudehone.com/index.html they will hone out your injectors and send them back to you. I plan on sending out my stock injectors and seeing how the run compared to my 275's. If they run better I might have the 275's done too. I would like to have something that is between a stage I and a stage II injector. The website says that they can hone out you injectors 20%. I need to call them to work out the details.

As for DD, you are right all they care about is the money. Slippery folks to say the least.

later.

Mike B, what happened with you and DD? They seem like nice enough people, and have been very forthcoming with info (at least to me).

They told me they will only EH new injectors in their machine, not used ones. I can buy that I guess. If EH offers the service to your current injectors, do them if you want. I personally don't mind paying for some peace of mind knowing the people who are doing mine offer a 200,000 mile warranty on them. What does EH offer? Do they just take the tips or do they take the entire injectors? Do they balance them as a set? They would need the whole injector to set that right? If you have a problem, will EH help or do they know anything about diesels?

Mike B - I too am curious as to why you feel the DD is 'slippery'? I have dealt with Lawrence and find him to be very upfront and fair, to say the least. I only wish all of the people that I have done business with had the same integrity that he has shown in his dealings with me. COLOR ME A VERY SATISFIED CUSTOMER.

Good news Good news!!!!!!! Talked to Extrude Hone and we have a new sorce of MORE POWER!!!! They will extrude hone our stock injectors 20% which is about the same as the 275 RV injectors, and if you have already bought the 275 RV injectors they will extrude hone them 20% which is same as stage II 1/2. $180 is the going rate. Another beifit is you won't have an unused set of injectors setting on your self collecting dust. If your engine does go south and they tare it down it will have the stock part number. Stealth!!!!!!!

Mike, are they also balancing the injectors, or just doing the honing? I was under the impression that the balancing of the injectors was some of the power gain.

Mike - I may be wrong in this case, but I have found you usually get what you pay for (and never any more). Also, what do you do about a vehicle while your injectors are being redone. That would have to be at least 4 to 5 days unless the company is close enough for you to deliver and pick up your injectors.

I phoned the number for Extrude Hone. The guy was very nice, and he will do your injectors for the $180. However, he will not reassemble them. You either have to know how, or contract it out to a shop. This would add to the cost. You could have the shop set the popoff pressure, at more cost. I did not check to see what that would be.
After thinking and discussing this subject, I feel that I can understand why DD will not do our injectors. He would have no control over the quality of what is sent. Could be, as in other core exchanges, he would get some real crap, then have people want him to make them work(and well)! Don't forget that if someone had this done by DD, and they were inferior, at no fault of DD, the people would surely blame him or at least be a bad advertisement. Controlling your parts is essential for your reputation and business. Although many of us have very slightly used injectors, it would only take a few bad ones to ruin a good reputation.

Well, since you asked I will relay my thoughts about my dealings with DD.
when I spoke to Keith about purchasing a set of stage III injectors I informed him about the upgrades I had already done. I wanted to make sure they wouldn't smoke too much since I am running a TST flashed ECM. I already was using the RV injectors at the time and told DD That the only time I could really see any smoke was at night when a car was behind me. I was told by Keith that the stage III injectors would only smoke a small amount more than the RV injectors did. He was very nice on the phone and took time to speak with me and seemed to know of the TST flashed ECMs. I called back a few weeks later and ordered a set of stage III injectors.
the injectors came but they were the wrong ones. DD sent the right set out next day. so far so good. I installed the injectors and took the beast out for a test run. Gobs of power but it smoked like a sled pulling rig. I have never seen a dump truck smoke like this. I took a 200 mile trip the next day and when I got back the side of my tuck was covered in soot. I took out the DDIII and sent them back along with the wrong ones they sent out the first time. (never installed the first ones).
DD said that they would check them out but wouldn't refund my money due to too much smoke. This was NEVER mentioned when I first spoke with them. He was only going to credit me $400 on a $700 set of injectors.
Keith said that they would install my injectors in the owners truck and put a clip of it on the DD website to show that the injectors don't smoke. I never saw this done.

I took the injectors back and sold them to somebody who doesn't care about smoke.

When I got the injectors back from DD they didn't send them back with the little boxes for each injector, the plastic caps for the injector tips were missing.

In fact they just put the injectors in a ziplock baggie and put the bag in a small box.

Since that time DD has change there website. It now states that they don't recommend the injectors for what I TOLD them that I had. It also says they don't do refunds for TOO much smoke. IF IT HAD SAID THAT IN THE FIRST PLACE I would have bought Stage I injectors.
Hell, they could have make me happy if the credited me $200 and sent me a set of stage I injectors. That was too much for them to do.
done is done.

I told them that I wouldn't go around bad mouthing them unless somebody asked.

Ohh. . one more thing. Keith also said several times "you can just sell them to one of your little buddies on the TDR"

Yeah nice guys.

later
Mike

Gee that smoke thing sounds familiar. Some people like smoke. I didn't. It smoked so bad no matter how you drove ot, it was comical, (for a while). Two trucks, FOUR sets of injectors later, Both trucks are back to stock injectors. During the testing phases, The DD guys were VERY cooperative. They gave me refunds without any problems.

I noticed that DD now has a discalaimer on their site:
"Stage 3 to be used only for serious horsepower requirements. This is not for the faint of heart.
If you don't want smoke, stick with Stage 2 or lower. "

Good advise!

Is it possible to have the exhuast turbo housing extrude honed. Maybe to give it a better exhaust flow through the housing, to lower EGT's and have a faster spool up.
I've never looked inside the housing, but it might do something if you were to smooth out the roughness?
Thanks

I am under the impression that turbo housings have been extrude honed, not sure if is worthwhile. There has been some talk about extrude honing heads and exhaust manifolds too. This is scuttlebutt I have picked up, topic for conversation #ad

When I interned at Garrett Turbo I had a few compressor housings extrude honed & tested. THERE WAS NO IMPROVEMENT IN ANY OF THE HOUSINGS.
I suspect that one would see the same results on the turbine housing.
