Any more info on this?

bump for more info....pricing, power, anything.

Heber, what size is the inducer on the compressor on the turbo you are runnin?

Teddy Bear

Thats what i wanna know. How big is the inducer? This could be a great choice for a puller

Any new info???

OT-OF-Here

I was wondering that too?

Rumor has it there's some controversy with the new SS housing. Not the kind I wanted to hear either because I have one on order. Maybe HeberRam would like to elaborate.

The a5000 has a 71 mm compressor, not turbine.

I am pretty sure the SS turbos are still based of of the S300 with your choice of 62, 64, 66 mm compressors.

Here's the info on the A5K's wheels:

AFAIK, the turbine wheel on the HTT 71 series (and the SS ones I assume) is about the same size exducer as the A5K.

I was wondering what the exh housing is?? And is it the same on the standalone a5k and the one used in the twins??

HeberRam

The HTTss I'm running is a 66mm compressor (front side) and a 71mm turbine (rear side) with a 16cm housing. We are going to either experiment with a 66mm and 73mm w/16cm housing or 66mm and 73mm w/13cm housing in the very near future. The 71mm & 16cm housing combo doesn't match my drive pressures correctly, and loses some top end power.

I woulda thought they were runnin a 74mm turbine with the SS versions. I bet the 66/73/16 would be a nice set up. I still dont know if it would move as much air as a A5K though.

OT, dont quote me but I THINK the A5K is some where around a .90 A/R but I may be wrong, I got too many numbers floatin around in my head so I am not real sure.

The Cummins Aurora 5000 is about a 0.80 A/R the Dmax is a 0.90 if I remember right. Not sure what ratio the twins version is.

Heber....can you hook me up with someone beta testing the 13 screamer. ks

Actually the Aurora 5000 wheel is 76mm at the exducer. Looks like ATS made a mistake when writing that tech info up.
The HTT71 series, Silverbullet, SuperPhat, HTB2, or whatever they are calling modified S300's this week are all smaller than the wheels/turbo that ATS uses for their Aurora 5000.

Here are some pictures with measurements of my "backup" Aurora 5000:





You can clearly see the diameters of the wheels Compressor: (2.8")71mm@ Inducer and the turbine: (3")76mm@ exducer.
I couldnt fit my slide rule inside the wheel housings so I measured out a piece of a post it note

HeberRam

Don't know of one yet running the 66/73/13cm? The problem might be getting the 73mm wheel to fit in a 13cm housing? It would probably be a 71mm. With the smaller housing this thing really should be a screamer. I'll probably be testing the 66/73/16cm in the very near future, and then whatever, the combo for the 13cm after that. The housings need to be honed out to fit the larger wheel due to the much larger wastegates....
