Once you reach 500+ HP there are some issues you must be concerned with will driving on the street, such as...

1. Getting the tires to stick. After 500 HP good street tires begin to fail and extra hp is moot and a waste of money.
2. It takes a skilled driver to control 500 hp effectively and safely on the street!
3. 500+ HP in a muscle car is alot different then 500 HP in a exotic car, cheaper suspension, tires, brakes, makes it more dangerous.

The more I think about everyone saying we want more HP, that is rediculous. 425 is great stock and a few mods, CIA and exhaust will boost an srt-8 chally in the upper 400's. The 6.1 is unofficially rated above 425. 450-475 HP in a chally is plenty to make any street racing contender nervous and in my opinion will keep you under an amount of HP that just gets lost in the spin!

We are lucky to get all this hp coming our way. Lets just not forget how much power that actually is and enjoy it while it lasts.
