I think it would be safe to say 8-10PSI at 5k RPM is something to shoot for. So, we are looking at the engine taking in ~218CFM at 5000RPM's N/A. To create 10PSI in front of that we would have to have ~500CFM. Can the S60 do that?
No. It can not. S60 can produce a max ~450cfm at 20psi (2.4) At stall - safe limit is 410cfm...
The Map listed shows that. (that's why I'm confused about GoodwinToo saying it's big enough?)
His math shows 290cfm (22 lb/min) at 4k & 408cfm (31 lb/min) at 6k (@ 10.5 psi) Though those numbers are rated higher than the compressor map for the S60 shows???
Since the map shows a max of 25-26 lb/min (330-350cfm) for 10.5psi (1.7)
I just re-did his math - He's off by 100cfm!!! That's the problem... I knew it didn't look right. Never took the time to check... I'll bet that's also why he told me 510cfm max flow when I said 410cfm
The numbers I gave last post show it's limits at 10psi (300 safe to 350cfm max at stall - I.E. high rpm)
