stage 1.5 beat stage 2 in this department too.:hello:

can you link me to the dynosheets?

here is a link about the whole stage 2 kit,note the 523/372 run thats with the 84mm pulley that he won't sell anybody it is basically a show off pulley that no one gets.

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...

What numbers are you referring to?

------------------- 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

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

What kit did you order exactly?

the 1.5 kit:happydance:

You will like it,it can put out a lot of power,congat,:happydance::driving:
