I was told to size the exhaust wheel for the power you want to make then size the exhaust housing a/r for when you want boost in the rpm range..

I have run both the .70 a/r and the .55 on the dyno. Same wastegate settings yeilded peak boost about 700rpm sooner with the .55 with no sacrifice in power at 6000rpm. I took it to 6200 on one pull but my gut chickened out before the power dropped.
