That is interesting...

Regarding the pulley though, why not have one custom made?

I'm going to Z Nationals Oct 4-6 I have been dialing in my tune for a while now ,I think I have it as good as it gets,I going to put it back on their dyno and see what happens I'm hoping for 520-525 rwhp and 385-400 rwtq.

It takes more power to spin the -91 (looking at the numbers I would say 12-13% MORE), so you end up with a loss as it only pumps 11% more air...

------------------- C38-61 C38-71 C38-81 C38-91/92
Max flow rate Mflow 0.48 kg/s 0.55 kg/s 0.58 kg/s 0.63 kg/s
Max pressure ratio 2.90 2.82 2.85 2.94

Air flow as listed by Rotrex

There is no free lunch, so to compress more air takes more power.

I am still looking for a compressor map for the -91

there is no free lunch. well worded sir lol

i'm calling the shop in a bit. i'm slightly hungover and my coffee has yet to kick in.

Baer, I'm interested in what you put down at Z Nationals. looks like i should start gathering info and tune my own stuff. lol

snowsurfdirtx · 09-16-2013, 05:56 PM

order is done! looks like i'll get an early birthday present this year.
