I can't tell much about your pics.
Sorry

But if it has AR on it prob is an Air Research.

Talk about some turbo lag!!!!

 

I have a VT50 setting on my garage shelf right now. They ran the 50's on the 855 Big Cam Models.

Mine doesnt show any marking of AR. So, it could have been a rebuilt unit from Air Research. I know they used to be a major supplier to different engine mfg's.

 

The housings should have the A/R cast in. It will be either on the outside of the housing, or on the inlet to the exhaust housing. The Compressor A/R should be listed externally.

I wish Holset Turbo's were listed with A/R!

A/R =The Area / Radius ratio
A = Area of throat at intake
R = radius of scroll in the housing of either the compressor or exhaust turbine

 

thanks to all that stoped and added to this post . but hears my problem in the pic of the compresser side it has no a/r or scrool it is all one size. i cant find a compreser map to save my life . so if any one can come up with some ideas that woud be great thanks for youre time
