I think the only set made are malone's, which I kind of think are still sitting in my shop, or maybe he has them now, regardless I don't think anyone has tried them yet. I'd sure like to try though!

You know Dave,
If you really need a digital camera I will be glad to bring mine up. Just leave the back door to your shop unlocked and I will go in and do a midnight swap. err......I mean drop it off for you

I have been calling around trying to find someone who could give me some info on flow rates for the merc injectors, no luck. The worst people to talk to are the people in the dealerships. " we dont sell vw parts." " I know, they swap, please tell me which injector for your 300 series td has the highest flow rate." " What?" " You know, flow rate. How much fuel it puts out." "Uhhhh........you mean for a vw?" " Thanks for your time, have a nice day".
Well, I found a small shop near my house that does injection service work. I asked this guy the same question. " I'll have to check my flow rate data. Give me a call back tommorow" Sweet.
I call today and the guy tells me he has some people checking on it. Since he asks, I tell him about my build plans. The guy must know his buisness becase he tells me, you will have flow problems at high RPM, you may want to look at a Cummins pump, that way if you want to go to a M-TDI in the future you should be all set, it can be modified to put big fuel out. He also said he was thinking that road application nozzles might be a roadblock to big fuel. He said he was going too research offroad and marine high performance nozzles. He suspected a direct swap and a 155 BAR operating pressure. Flow would be greatly increased. " They might put so much fuel you might burn a piston." Yeah Baby :!: :twisted:
I will get in touch with him later today. Will keep you posted.

LOL! Yeah! "It's not enough fuel unless I can cut through metal with 'em."

Keep us posted! I'm tryin to find some merc injectors but i'm still not 100% sure if they will be higher flow.

subsonic · « **Reply #21 on:** March 21, 2007, 08:11:29 pm »

OK,
I think I will drop off a set of injectors at this guys shop. For your reference the nozzle he is talking about is............................................................................

a Bosch nozzle, he designated it by the part number as 8S2. He is still waiting on a callback on the actual flow rate, but said this nozzle will put out 2 to 3 times as much fuel as a stock 1.6TD nozzle. Read that as
200-300% increase in fuel. :shock: Next question. Should I load these bad boys into 1.6 or 1.9 injector bodies?
If any of you have contacts with anyone who deals in bosch nozzles please hit them up for any information you can get on these. I will not know for a few days (going into the long portion of my work week) if these are spec'ed for marine, off-road or industrial use. All feed back is greatly appreciated. I really hope this pans out. If these puppies really flow that much more fuel, what would that mean for advances in possible power? Will I have to buy federal smokestack clean air emmission credits to run these things

Dig deep, go forth and shake the bushes and report back with intel.

So could you just order a set of nozzles and use that p/n? Where to get?? I'm in need of rebuilding my injectors and would much rather go this route!!! :twisted:

subsonic · « **Reply #23 on:** March 21, 2007, 09:37:28 pm »

Well, like I said. I'm going into the long part of my week. I probably will not be able to get in touch with him again until monday. I work 10 hour shifts. I am pretty sure these are not automobile spec injectors. He mentioned high perf. off-road / marine or industrial. I know that makes it kind of hard to research. Had dinner going and kids crying and fighting while I was trying to talk to him on the phone :x . That is the part number for the nozzle as far as I can tell. "You could go with a bosch 8S2 nozzle." I would try them out in my ride when I get them done, but I am driving a 1.6NA that is tired. I don't think it would be worth it to me to put them in until I get my build done. Also, I have never done buisness with this fellow. A very reputable diesel shop reccommended him, and he appears to know his buisness, but thats as far as I can go right now on vouching for him. When he gets all his details together, price, flow rates, full part numbers,, catalog ref numbers etc. I will pass it on. He said he did not have this part on his shelves, but it would be no problem getting them in. He wanted $20.00 per injector to do the swap and pop test to what pressure you wanted. Not sure if that is a good deal or not.
Will keep you posted. If, and I say if, it works out, I would have no problem passing on orders to him, or picking some up and mailing them out if you wanted some and could not pick them up from a local seller. It would be nice to have a couple sets of comparison data inputs from different engine setups to see if this really would be benificial.
Talk to you soon, Jim

foxracer1 · « **Reply #24 on:** March 21, 2007, 10:01:55 pm »

Well i'm interested for sure. In the near future i'd be interested in getting some. I'll call a few shops around here and if you get any where let us know. Awesome find!

subsonic · « **Reply #25 on:** March 28, 2007, 04:19:54 pm »

OK,
I've tracked down the Bosch part number for these nozzles. The nozzle is a DN8S2 Bosch part# 0 434 200 012
Whole injector is Bosch part# 0 432 226 003
This cross references with a Mercedes part# 605 300 100 013

I was unable to get flow rate date still. It is supposed to be way more.
I was told that on the complete injector its operating pressure is 125BAR

Could we use this nozzle at a higher operating pressure?
If anyone out there can use this information to try and find some flow rate data that would be great.
If anyone has the Bosch part# for the 1.9td injector I need it for the Bosch tech to see if this will fit in the 1.9 bodies. He said it willl fit in a 1.6
body.

AFAIK, 1.9TD nozzles fit the 1.6 injector bodies so they should work.

foxracer1 · « **Reply #27 on:** April 01, 2007, 09:57:59 pm »

I would think you could raise the pressure up to 155bar if you wanted. I believe it would lower the flow just a little but they are already flowing more i'm sure.

What's about the DNOSD261 mercedes Nozzles?

I looked with Esitronic for DN8S2 nozzles and it do not have there mention for Mercedes.

foxracer1 · « **Reply #29 on:** April 02, 2007, 09:11:16 pm »

I called 2 shops about the DN8S2 nozzles, they both quoted me $43 a piece. Does anybody have the Bosch PN for the DNOSD261 nozzles?
They also said it would be about $22/ injector to pressure test and balce them. $65/ injector $260 for a set. I guess thats not bad, but more than i want to spend right now.
