you''re gonna hate me, but my guess is 115hp and 120ish tq.
it really just depends on so much, put it together and get it tuned up and lets see what it does. for the record, i hope that it does what you hope/think/estimate.
good luck with it.

Really good builds are very dependent of precise compression.. It truly is the driving force.. Don't get me wrong all the components need to play well together.. And I don't believe in over exhausting durations..

I'm curious why you think so low? I have a pretty good idea and that's ok. In this case, with the Pro Streets, I like being the underdog. Everything is there to beat your torque numbers otherwise including compression at 210 psi. I think a whole lotta people are going to be surprised with the exhaust. I'm sticking to my 123hp/127 torque. Especially the 127 torque. I know the 9B will carry out a little further so hp a few less than yours is likely. I am running higher compression tho too.
I'm basing my guess off a few comparisons one of which was on Tman's dyno page also a 107/590 build but at 10.5:1 and with the Long Shots. It did 119/123. I know the streets will do better than the long shots and my compression will be significantly higher. I hate to guess at what the CR will be but higher than 10.8 which would be 205psi CCP. I told Kirby I want to be closer to 210psi so 10.9? 11.0?
Of course the other dyno I'm using as a comparison is djl's 98" build at the same compression with the CR595s also with the Pro Streets and in a Softail too I think that did 115/115.
I'm also going to be testing the Khromewerks HP Plus and Rush slip one with the stock head pipes and crossover and TBH, I expect to see your 115/120 out of those. Especially the HP Plus.
Probably hooking up with hrdtail for this tuning.
