Default PERRIN has new toys... GTX results inside!

I am sure everyone has seen the new info about the new Garrett GTX turbos and maybe seen the generic pics Garrett supplied to the media, but here are some up close and personal pics! Sorry for the somewhat less professional pics taken on my desk, but i was so excited when they showed up that i didn't want to wait!

Pictured above is the GT3071R, GT3076R, GTX3076R, GT3582R and GTX3582R. Its easy to see the billet wheels from this angle and size of them really stands out.

You can see the compressor housings are the same design but machined to fit the slightly larger GTX wheel. Its not just the ID of the housing but also the shape of the curve that fits the compressor wheel. They still have that annoying/ugly and not smooth lip from the surge port transition to the ID.

Garrett provides this info on the compressor wheel sizes, but what they don't say is what the actual OD of the wheel is!

Turbo______ Inducer____Exducer___Trim __AR
GT3071R_____ 53.1mm____ 71.0mm____ 56___ 0.50
GTX3071R____ 54.1mm____ 71.4mm____ 58___ 0.60
GT3076R_____ 57.0mm____ 76.2mm____ 56___ 0.60
GTX3076R____ 58.0mm____ 76.6mm____ 58___ 0.60

The GTX wheels use "New Aero" but they do not mention the extended tips of the wheel as a feature. Probably because BW uses this feature. Its a greats simple way to get a little more air flow from a compressor wheel

The Exducer on the GTX3071R is 73.45mm (2.05mm bigger than claimed) and the exducer on the GTX3076R is 78.7mm (2.1mm bigger than claimed)

Taking a look at the compressor maps you can see that now customers looking to make 400WHP may opt for the faster spooling GTX3071R instead of the GT3076R. The GTX3076R looks like a 35R now and as long as it still spools fast, it may be a great option for those torn between the two sizes.
