Somewhere between .48 or .63. It just depends on what the exhaust flow looks like on that motor

Dear sir.
I tested the T-58 with a oncenter a/r .81 p-trim but i think i need a a/r 96. Builds boost before 1500 rpm.

Do you still supply the part nr 20296-3?
Do you have a ported shroud housing for the compressor? T-58 TS04

Best Regards Christer.

Unfortunately there aren't any parts for the older P-Trim turbine wheel anymore. Turbonetics moved to a new turbine wheel design several years ago and all the remaining parts for the original P Trim wheel have since been sold.
