The eaton blowers will not overpower the stock crank so you will have room to grow. I think you may be a little conservative on your hp estimates.
My I have a few friends from digital corvettes in AZ with eaton/TVS
LS1 W/1900 ~485 rwhp
LS2 W/1900 ~550 rwhp

good advice. |

I would definitely drop the compression. I believe an LS2 is about 10.6 to 1 and that's not too blower friendly. You will want more power in the future, trust me. Having the lower compression will allow you to step up to a TVS2300 or add in more boost later once you get bored.
Not sure on the TB, I'll find out what the stocker flows.

FWIW, I think if you did a stock CI low compression blower motor with a ported blower you could easily make 550+ wheel depending on your fuel system.

hummm....That seems a little high for a low compression, an ls2 stock is 10.9:1 so if i split the difference and run 10 so i have room to grow but still not giveing up to much power at the current time |

The best advice I think I can give is to figure out exactly what you want to do with the car. Drag, Road race, TT, killer street machine, show (Gay) car. Be as clear as you can be with CMS and then listen to there advice. It's easy to find guys to tell you to drop the dollars and go big, but if you aren't racing then what's the difference between 550-650-750?
As far as compression goes. I would stick with the stock compression unless you are planning on running an excess of 12 psig. Honestly 12 psig came straight from my ass, but that is where my gut separates big and little boost (for v8s).

I was thinking the same thing. My motor can take 8psi all day long and forging it will only make it stronger. I want to have it a street car, that I race about once a month, Auto cross and road racing. I only want the number to keep me happy.  500 rwhp is the number i want so i'll see how close i can get. |

How much power were you making before? I was 460 rwhp with HCI. You can definitely get there.

I'm telling you, lower compression - boost is addicting. I'd go somewhere lke 9 to 1 and crank the boost up. That MP112 (especially with porting) will easily handle 15psi. 500+whp should be easy.

15 Pounds is alot for that blower. I have 6 liter motor so the most you can get even with overdriving it and a 2.7 inch pulley is 12 pounds |
