Looking on the web last night for turbo calculators, I found one at bsmotors.com. I liked it because it had the compressor maps along with the calculations. One thing I noticed was to a point the bigger the turbo the cooler the air inlet temperature to the engine. The difference between the T04 and T-61 was like 50degrees centegrade at 1 bar of pressure.
One thing the calculator didn't provide was where the T-61 would spool up in the rpm band. Obviously the sooner the spool the more usable the power range. According to this calculator it seems that the T-61 is the one for me at 1 bar pressure. It also seems that we would be way out of the T04 compressor map for best efficencey.
If I am wrong please tell me. I don't mind spending the money but I hate wasting the money. I realize I will have to beef up the internals to play with this kind of pressure. By the way .8 bar makes 437 hp where as 1.2 makes 523 hp, according to this calculator. Oh well somebody stop me!
