RB26DETT Airflow

[djr81]

I have an APEXi Power FC controlling a largely stock GT-R motor, with just the usual filter/exhaust mods.

Can anyone help me to convert the displayed output of the airflow meters (Voltage) as seen on the Power FC controller into either a cfm measurement or a lb/min measurement. The flow meters are standard R32 RB26DETT units.

I want to compare this figure, ie the stock turbo flow in lb's/min to the compressor maps for the larger Garrett GT 25 30's and/or the Nismo N1 turbos.

As an aside does anyone have a compressor map for the stock R32 GT-R turbos?

Also, wanted to buy - Standard R32 Rear speakers & covers.

I think the compressor is exactly the same as the ones used on the T28 on the S14. That means its the T3 60trim compressor which u can find the map here;

However the RB26DETT might use a different trim, not sure.

Thanks for the link. Unfortunately I don't believe the two T28's are one and the same. The reason for this is that the N1 compressor map recently published in Zoom is smaller in both air flow and boost than the T28 map shown by Garret.
