Garret?
Does the stock Garret turbo have a 1.00 A/R Turbine housing? Never looked until yesterday
to see if maybe i was moded for the WW before i bought the truck. My truck sings pretty loud with just the 6637 Filter, checked the fins pretty close on my stock wheel and it looks brand new, bummer though no WW inside Thanks B

The turbine (exhaust) side of a stock truck turbo is 0.84 A/R. The compressor (intake) side is a 1.0 A/R, but the A/R ratio on the compressor side typically isn't something we take into consideration. It's the turbine side that has the most impact. Also, my stock turbine housing was not marked with the A/R ratio.

The aluminum (compressor, intake) is the 1.0. The cast iron one is the turbine and it drives the compressor via a shaft.
