DSS Ultime Nozzles

snadam · Nov 5, 2009

Are there any resellers of the DSS nozzles here on Fred's forum? If not, can someone point me to the 'official' site of the manufacturer or the main distributor? I've tried numerous searches both here and on the major search engines and I'm not coming up with much. I just want to know more about what is offered and at what price.

Thanks,
Adam

I'm running them in my car. I liked them, had no complaints at all. I got them through RedRotors on here. He's the NA distributor.

Official website is down since a few months: www.diesel-speed-shop.com

David (DSS) told me the new website is under construction. It may take a while, though

I wonder how their largest holes compare to the Nicktane stg. 7....?

Will an 11mm IP even support huge holes like that? Or do you have to resort to 12mm pump head upgrade?

Comments from anyone running huge holes?

hatemi · Nov 5, 2009

Ultime2 with 0.28 holes works just fine with stock 1z pump

And give 37hp more with less smoke than 7 hole R520. Best numbers with stock ALH pump I've heard of is over 230hp that TDIfreak got.

snadam · Nov 5, 2009

What are the various models of DSS injector? What are their sizes and do they have names like the Bosio nozzles? I've seen "Ultime2" thrown around here on the board and I assume that's their biggest nozzle but what others are in the product line?

Are they all 5 hole or do they have other configurations?

If nozzles are purchased can they be installed, balanced and popped on the same benches that are doing BF nozzles today?

Rub87 · Nov 6, 2009

yes 5 hole, ultime I should be around .26 and ultime II around .28, I think Hannu did a run a gained around 20hp from going from 5hole r520 to ultime I..

I'll be trying ultime I in the near future..

kooyajerms · Nov 6, 2009

since the sites down, anyone want to tell us how much the ultime I and ultime II cost for a set of 4 shipped to US?

hatemi · Nov 6, 2009

At least here they are cheaper than bosio.

We tested Ultime1 and R520 in my car set after another and got 272hp with R520 and 295hp with ultime. IQ was around 2 on those runs and the pump was not your regular "upgrade"

Bosio R520's should be somewhat comparable to a Nicktane stage 5.

So what do their stage 7s compare to?

Are they a .300 hole size?

With a VNT-20, 11mm + PD pump, & head port + cam can I support it or will they not atomize correctly? What upgrades would make those holes work....aside from nitrous..

I don't know the hole size, but the stage 5's are ~132% over stock and the stage 7's are ~171% over stock. The stage 7's flow just a little less than the 7 hole R520's which flow ~173% over stock....but I would think the atomization would be much better with the stage 7's. I have a feeling that the stage 7's might be a little more than you need.

Why are these nozzles not more popular then if they are just as good and said to work better then Bosio nozzles, very few people seem to use them and nobody i know sales them plus they are hardly ever talked about on this forum?

Because Bosio has been THE nozzle for so many years and a lot of people trust them. Even if an alternative product is proven you can't expect things to change over night.

stage7's are quite big.. with 10mm camplate and 12mm head they only seem to come alive after 4000rpm, then they're really a blast, but midrange is only smoke.. probaly due the too big holes and too little pressure, I had shimmed them at 270/390bar IIRC..

Alex tdi · Nov 7, 2009

what size is nictane stage6?

If they really are a little less flow than 7 hole R520s that I had I should be ok with it. Not concerned with smoke where I live now. It's windy...

Isn't Rich running these in a daily-driver?

Rub87 · Nov 11, 2009

they flow imo more than 7hole r520, 7hole r520 don't flow that much, the smoke is just because of the bad hole placement. stage7 come really to live after 4000rpm, where the 7hole just suck at every rpm expet for idle and very lean conditions
