Car has a Saleen blower but some other major mods. Also maybe consider the Roush set up.

I'd look at the FRPP Whipple though too. You can kept the boost low and safe. Then if you decide you want more power you have the option.
Klaw, you did the install yourself?
The Roush and 400 hp Whipple both come with a warranty which may or may not be important to you. The Roush starts you off at 445 hp while the Whipple has more portential (500+) if you ever decide you need more. I am happy with the Roush blower. There is a video on youtube where a Roush 427R outperformed a Saleen 281SC that had more claimed hp.
A fairly standard installation time at a shop is 8-12 hours from everywhere I've seen and talked to. Most shops will even get you in and out in one working day. Many people on here have gotten the install done for $800-1000, but the cheapest place I have found so far near me has told me $1500.
To somewhat answer your question, they claim its 475 hp, so I'd have to imagine +175hp at the crank would easily give you +100 at the wheels.
