Boss Sr. A/R size?

[blk92suprat]

What is the compressor and turbine A/R's for the BOSS Sr. turbos?

Is the A/R any larger on the GTS Covers?

Doesnt say anything on the website and the number on their website just keeps ringing.

im almost positive the a.r is 58. they have an after market exhaust housing you can buy thats an 81. http://www.suprasport.com/BOSS-Turbos_ep_41-1.html

I think the housing is smaller then .85 by the looks.

Anyone know the correct size of the exhaust ar?

The Jr. is .58 AR and the Boss Sr. is .83 AR You can reach me on the shop phone 651-342-0100, this is the only one I can hear.
