Hey guys , does anyone know how to convert CC's (1300) to Cubic inches or liters? I was trying to figure HP per cubic inch on the Busa. As far as Liters goes I think its 62 cubic inches per liter .. I was thinking the other day that Its easy to get 2 HP per cubic inch on a chevy 350 what about a Busa?

So what you're saying is, 1300/16.387 = 79.33 Cubic inches. Stock Busa about 155 horses. 155/79.33 = 1.95 horses per cubic inch. Add a powercommander and full pipe, you're looking it 165/79.33 = 2.08
Give or take.

155 hp as long as your measuring at the rear wheel. Every car Hp I've ever seen is measured at the Crank, so that would put the Busa at about 165 Hp

Good point. Then 175 at the crank after slight mods and you've got 2.21 horses per cubic inch.  
It's a good engine, what else can you say?

Wow, I would never think it is "easy" to get 1 HP per cubic inch from a naturally aspirated car engine or even a v-twin motorcycle engine on pump gas. Just curious how you can easily get 2hp/C.I. on a chevy 350.

The Busa is rated 175 HP at the crank bone stock. It even states it on a certificate you get from the dealer which you give to the bmv to register and plate the bike. 165 HP is CBR-XX territory.
 
High output engines achieve the 2hp:1inch ratio due to high rpm capabilities. This is inherently easier in smaller engines with relatively low reciprocating mass.

The Hayabusa achieves these numbers at RPMs that a stone age 350 could not spin to without ultra high end fueling and rotating components. It would be a fun way to grenade a 350 though.

The only way to get that ratio out of a naturally aspirated chevy 350 would be to use power adders or alternative fuels such as Alcohol with appropriate tuning, compression and fueling upgrades.
