HP guess

I'd like to ask some of you guys your opinion on my estimated hp/torque output if I could? Had something happen to me today that got me concerned about the 915/61.

I have a 77 930 engine with around 500 miles now. Inside is sc cams, stock pump, dry film lubed cams, rockers, skirts, pins, stock 6.5/1 pistons with powercoat on top and combustion chambers. All bearings also received dry film lube treatment. Turbo is GT30r 3076 milled on the intake housing from turbokraft. Spring is .6bar but it only makes .4+ bar. I use an innovate wideband and see 2.6-2.8 afr under full boost. I have a .8 bar spring that I'm waiting to put on till I do my first valve adjust. No inter-cooler at this time, have wmi not installed. Car runs really strong and I'm thinking about 300 hp at least, it's fast. any guesses before I dyno?
Turbo powa!
1977 911s. it's cool
