Holset compressor map / info needed.

[TY162]

Anyone have a compressor map for a holset VGT turbo HE551V ? I haven't been able to find one (and Yes I've been looking lol). This is the info I have found on it so far. Comp side 71mm-108mm. Turbine side 86mm-75mm. VGT 9-31cm. 75kg/s. (99lbs/min?) I would be looking at a pressure ratio of 1.5-2 (10-15lbs) Anyone know what the CFM would convert to or the power this turbo could support?
Thanks

Are you sure you want to use that turbo? VGT turbos have virtually zero lag but are very expensive to rebuild. An HX35/40 hybrid would get you around 600hp easily and a lot cheaper. I almost went that route.

Well, hopefully I won't have to rebuild it. It won't be going on a 4.3 st/ty, I have a couple other project ideas and was just looking for a little more info on it.

If you ever buy a used turbo, plan on rebuilding it. I'd love to hear how it works out for you though. It would be especially interested in hearing how it works on a SyTy.
