Powermax vs ATS Aurora 3000, currently have ATS but have a chance for a good deal on

Wondering the differences or gains/losses in switching to a powermax?

Currently have the ATS aurora 3000 that came with the truck, but I'm looking for some more juice.

I just picked up an SCT tuner, so I may give it a shot and see what I can pump out of this ATS before upgrading.

What do you guys think? Can I squeeze some juice out of this ATS or just pick up a powermax?

I think there are better options than the PMax, but I'd get a custom tune written for the ATS and run it before giving up on it. You could find that you like it. It's a small charger, but has a nice compressor map, so on a stock injector truck with intake , exhaust and tuner, it should run well.

What year is your truck? I have a brand new MTW stage 2 I need to get rid of. It won't work with my early '04. I'll give you an awesome deal on it if it'll work for your truck

Won't work or don't want to run it? Just curious.

I think you can get more ho out of the powermax. It's a bigger turbo. However the ats 3000 should have less lag. So even though the powermax flows more air you might not like the way it drives if that makes sense. Get a custom tune written for your ats but powermax gets my vote.

You must remember that a nonVGT turbo WILL ALWAYS out flow a VGT turbo on the top end and sometimes I'm the mid RPM's as well, even though the nonVGT may be smaller. Lately, companies like KC, Barder and VDP have been experimenting and building VGT's that level the playing field. Still, you'd be hard pressed to find anyone with even a little bit of knowledge about turbos that would claim in a side by side comparison, two like sized turbos (68's),one being VGT and one being nonVGT, would flow close to the same. The nonVGT always wins up top and the VGT wins down low.

In this case, I believe the ATS would out spool an out of the box PMax, but might be over taken by the PMax on the top simply due to size. The ATS is small. I'm not sure on its capabilities, but after a little research, it seems to be a stout turbo capable of 35 psi on a tuned, stock injectored truck. My vote still goes to getting a custom tune written for it and rolling with the ATS.

Matt thanks for that info. Why do non vgt turbos out flow up top I understand why 2 of the same sized turbos down low the but wins but why the non vgt up top. do the vanes not completely open even up top?

Well... the theory is that the vgt vanes get in the way of air flow up top in the rpm band.


but... I know I will get bashed for this... All the evidence shows that vgt turbo will flow the same as non-vgt turbos. People make similar power on dynos, tracks, and compressor maps say they flow the same... but everyone talks about non-vgt turbos flowing more up top.


The theory makes sense but I have not seen any data to support the subject.


I would put my KC 68mm stage 3 turbo up against any 67.7 FMW on similar trucks any day of the week... Not saying that I would win, but it would be cool to see what happens.
