I'm thinking..
 

Well i have a 08 Mustang GT lightly modded, Looking at doing the popular bolt on's or supercharging it with a kennebell. Kenne bell says their stage 2 (not mammoth) and stage 1 run full stock lil over 500 hp, unsafe having this much hp on stock motor?some have told me 450 is probably furtherest should push for a daily driver. anyone know if theres truth to this or whats the most power some have you put to the wheels with stock motor and how long its been holding up?thinking about maybe a light power whipple or roush charger if so and maybe just quit with the engine mods instead of putting so much into it and just save for something else. Thanks for the help guys n gals.

Anything over 450 rwhp is pushing it with stock internals. If you know your going with a charger then I would base all my aftermarket parts on that. Once you have decided which charger your going with call them and find out what all the kit comes with and what all you will need to buy. You don't want to spend money on aftermarket parts just to find out that they won't work with the blower your getting.
