I hate to do this but my dyno day is coming up and im trying to get an idea of what my car would put out n/a so then i can take a guess what it will be making with the turbo. Ive been told 20hp per lb of intercooled boost

The motor: 306 8.5-1 compression. Ported(i mean ported) E7's, ported lower intake, stock cam 1.7 rockers, stock thorttle body, 42lb injectors

HPPerformance turbo kit with t60 running 8psi for now...

Exhuast is 1 3/4 headers from the kit, downpipe is 3in, with 2.5in dynomax ultraflow exhuast.

IMO close to 350 rwhp... but i don't think it's that much hp/lb... a lot depends on your motor, how good flows, basically: intake/ heads/cam... even if your heads are ported they are still stock heads, which of course are very restrictive...

i'm getting my stang out of the shop in 2 weeks and i just got a 14 lb S-Trim... still got stock heads, a little bit ported, i'm probably gonna make 350rwhp... with a new set of 185 AFR's, which i plna to get his winter, i'll be on the 450's...

ohh yeah.. def bigger TB, change the cam, and get intake man... stock intake, heads and cam wont help you much.... but your on the right track
