Engine/Transmission (1998.5 - 2002) Aurora 2000 Questions

[BTowler]

I am looking for input on the Aurora 2000. Does it surge? Are you happy with it? How is it for low end? Midrange? High end?

 

[BTowler]

Somebody has to have a 2000... somewhere...

 

[zstroken]

why not use a HTT or an Industrial Injection turbo?? I don't think the Aurora 2000 is that great.

i have one and let me tell you its a great turbo over stock, well was at one point :-laf when i first baught the turbo i had just the DRAG comp box and intake. i was never able to get egts over 1200 at anypoint and is spooled just as fast as a stocker. now my problem is i have added WAY more fuel and now the turbo is WAY to small. works good to bout 350 to 400hp then she falls off pretty quick. boost numbers with the DRAG comp alone were 40 to sometimes 46. great little tubro for towing and such if your not lookin for all out hp then its a good choice.

 

[BTowler]

I'm not planning on going much further, maybe a set of jammer 3's, but you know how that goes... Just want to do turbo, trans, and sticks then call it quits... for now...

 

[zstroken]

Well let me know if I can help you out.

The A2000 is basically a stock S300. The turbine wheel is the same (2. 89 ind. and 2. 54 exd. ) and the compressor wheel is a 58mm.

Thanks Ross.



I have been looking at this turbo myself. Mostly because it is bolt on with a turbo mounted exhaust brake.



Check my mods, how do think it will run with my set-up?

To save you time and money I would get a SPS 62/12 for a second gen. That way "if" you ever do add anymore to it, you'll have no problem supporting the extra power... The 12 should spool pretty good with your application.

honestly it might be a bit hot. with my 170hp injectors alone i was never able to get over 1200 egt wise. with just the injectors and my DRAG comp on, i can hit 1500 pretty quick. with my DRAG, Smarty, and TST, well i dont even want to talk about it :{

 

[CHolman]

FYI, the SPS 64 was designed and geared toward the second gen truck... . If I had a second gen, that's what I would have gotten.

i totally agree 1000% only reason for gettting the ATS i have now was i was straight out of school wanting the first thing i saw and that was it. i am now trying to sell it even thought its a great little turbo and wanting to get a SPS 64/14. great turbo

 

[CHolman]

all I do is study this stuff and talk to and get feed back from people, so I try and give ya'll the info and or facts to save you guys money, time, and hassel...

Thanks Z. Under what conditions would you say this?



I am interested mostly in steady state towing performance. My problem, that limits allot of choices, is the turbo mounted exhaust brake. ATS touts this as a towing turbo. Comparing this to a DZ, which I believe is more suited more as a top end turbo.



Although I have heard there is a possible work around using HTT turbo with a 3rd gen exhaust housing using a fabricated adaptor plate. No one to my knowledge has done that yet. Any clue about that?

ATS says the 2000 is happy at 350 to 400 Hp, maxing out at 450 Hp. But, this is almost the same conditions that most of the other hybrid turbo manufacturers will say their turbo is designed to run at.



I have not been on a dyno, but I am guessing I am somewhere in the 300 to 400 Hp range, most likely in the lower 300's. I can run a little hot while towing and I would prefer to achieve the most usable Hp for my truck vice all out maximum Hp.

Jim

oh well if you are only running in that hp zone then you would be totally fine, this turbo works exceptional in that zone. but as far as adding MORE and MORE fuel, this turbo will get small very fast. as for me, i am in the low to mid 500hp range and boy this turbo like a stocker if not smaller since i have added way more fuel. hope this helps. if you are intersted i am selling one in the classifieds. e mail me if you want and i will tell you about it. -- email address removed --. see ya.

OK Jim,



Now I am confused, the ATS website shows "Perfect for Power Levels of 450 to 500 HP", where are you getting your stats?

Bruce

i think he is close to being right depending on crank hp and rwhp. i dont think that ATS means 450 to 500 rwhp. i think they mean at the crank becuase let me tell you its WAY to small for 500 at the wheels and i know from experience :{

 

[zstroken]

I need to see a pic of the turbo mount exhaust brake for the3rd gens. Some of the chargers bolt right up to the stock downpipe.

Sorry Bruce, I guess that did seem to come out of my kazoo. I got some information sideways as to what ATS proclaimed, my apology.



Check out TDR Magazine Issue 53 starting on page 11 written by Doug Leno. This article is primarily where I am coming from.



From page 13 bottom left corner.

Changing to higher fueling levels. I found the Aurora 2000 turbocharger to be quite happy in the 400 horsepower region, producing boost pressures into the mid 30's at 2700 feet above sea level. This turbocharger is well suited for maximum boost pressures in the upper 20's to low 30's as well as sustained operation at 350 to 400 horsepower. Its durability suggests that it could easily accomodate bursts into the mid 30's and 450 horsepower. Presenting abosolutely no surge behavior, this turbocharger appears to be well suited for towing.

It does not exactly say that it can keep 400 Hp cool, but thats a bit more fuel than I have anyways. I assumed RWHP was what Doug was writing about and he really only compares it to a HY35 in a 3rd generation truck.
