I have been lookin at differant turbos recently and it is frustraiting cause some list cfm, some list lbs per minute and others still have a differant way to list it.

My question is where can I find how many pounds per minute does an S300 based turbo flow? Like a 62/71/13, or a 64/71/13, and I would also like to know how many pounds per minute my SPS 66 will flow.

Thanks for any help

Thanks man, I have been lookin for that but couldnt find it.

I could call Nathan but I know it will be a month or 2 at least before I can get twins, so I dont want to call and bother him for ever and not buy anything. I know he wouldnt mind, its just that I first hand how that is.

YOu need a compressor map.

S300-based turbos should have maps similar to the ones shown here:

How would you convert a compressor map to CFM's?

Density of air: .076lb/cu ft

Yeah compressor maps would be nice. I stinks that all turbo manufacturers dont use the same yard stick to measure turbos with.

I realize cfm can be vague, as can the normal sizing, ie 62/65/13 cause there are more factors to what a turbo will flow other than just the size of the wheels. But it would be nice to be able to make an apples to apples comparison with all the turbos out there.
