At a guess, if its a 13b with your mods should pull around 120HP if the engine has been freshened up recently.
But if it's got a fair few K's(sorry it's mile's for you yanks ay)like say around 150,000'miles' then i'd think it would be around 100HP.
Not sure what engines and tune etc your cars come with so i'm interested to see what ya pull on tha rollers. All the best.

It's always been my experience that a clutch that slips occasionally on the street, will fail totally on the dyno. Prolly has something to do with the stress of trying to spin up those heavy drums. That will always make the weak link show up, and in this case it's the clutch.
Also, if you suspect it is gonna slip, you're not gonna get an accurate reading.

A cluch that fails on the street wont always fail on a dyno...
The dyno's is there to 'simulate' a roads surface. So it doesnt put anymore stress on your drivetrain than driving would... It's not as if you have to change gears on a dyno.... For power runs it just gets put in 4th(accelerated slowly thru tha first 3 gears-NO STRESS) an accelarated from 100km or so...
Think about the amount of **** that clutch would cop on tha street.. Poppin' gears, pumpin tha clutch an dropin it at high revs also what about those 7000rpm gear changes?? etc etc. On a dyno the clutch or box doesn't get thrashed out much at all. It might hamper performance abit but i'll guess that'll hold out...
Thats my input.
