Hello everyone.
This is our newest unit, the PT6466B. ( B = dual hybrid ceramic ball bearing)
It features a new 64mm inducer CEA designed compressor wheel, with a new PTE designed and produced 66mm exducer turbine wheel. (Not a sourced turbine wheel but our own design) This turbo will bridge the gap between our current PT6265 and the PT6765 turbos. Rated to support 800 flywheel hp it looks to be one very potent new unit. I would love to see one of these units be put on a 235 motor with cam and heads. My guess is it's going to blow people away with the performance and gains. As Louie said before, it features a newy designed compressor cover, based on the current SP size. It has what we call "The Accelerator." Meaning, the ported shroud has special fins that help direct and turn the incoming air to the proper angle. Basically pre-spinning the air in the proper direction. This helps promote quicker spoolup and draws more air into the turbo under WOT. This is our first gas based turbo that we have incorporated the technology into. It will be offered as an upgrade on other models later in 2011.
We have also come out with a completely new V-band inlet, V-band outlet style turbine housing that is casted in 310 stainless steel and will out flow and out perform the other T4 style turbine housings. This new V-band design housing will be available for the following turbine wheels.
65mm, 66mm, 68mm, and 75mm.
Two A/R ratios will be available. .81 and .96.
The .81 will outlow the curent T4 .96 and the new .96 will flow even more. I will also post pics of these new V-band housings asap and I will post more specs about the PT6466B turbo later this week once I get back in the office.
Later
