Engine homework, Is my math right?

[Shaolin Crane]

Ok ive been doing alot of research regarding what supercharger to run how much horsepower and what boost and compression ratios i want to run my goal is 800-850rwhp so according to static compression ratio, effective compression ratio relative to boost and a moderate engine compression for an effective street driven beast am i to assume my math so far is correct...
Effective compression for a moderate to heavily modded street motor is 18:1
assuming i have a 347 that makes 430rwhp (mods to do so are not important at this time) with 9.5:1 static compression(18.5 effective compression) will make the 8XXrwhp at 14psi of boost with 91 octane an a suitable aftercooler? Any more knowledge on the subject will greatly help me

I'll bite...
How is 'effective cr' calculated?

Your gonna need a pretty big blower and im thinkin more than 14psi to make over 800 to the tires. I really dont see over 400rwhp from a low compression N/A 347 either. I'd guess its gonna take an f-1c or an f-1r to make those kind of power goals

Yea, 430rwhp N/A with a 347 built for boost is a stretch.

You're going to need a BIG 'charger and just keep turning up the boost until you get what you want. A big top end, too. Lots of breathing.

800 on pump gas is gonna be hard with 347, easier with 351 stroked, way easier with a 460 stroker
