We made 570 rw hp and 630 rw torque today on about 8 psi boost on our customer's 2006 Charger SRT8 (thanks John!). Still completely stock motor and stock heads. Mods are: Hennessey SRT600 Turbo System with single turbo, front mounted intercooler, blow-off valve, upgraded fuel system (injectors, pump), modified Magnaflow exhaust with no cats. air fuel ratio is 11.7. we are running stock timing and 104 unleaded race gas until we lower the compression.

so far this package is making some pretty good power. i think with a few more tweaks it will make over 600 rw hp pretty easily. we are not sure how far we can push the torque converter and transmission but we are going to find out soon.

Here is the vid:

impressive. Nice to see a turbo on something besides a 3.0L inline six.

Nice, do you need another SRT8 to do your preliminary tests? I'd be glad to let you use my truck. :)

How cool is that (or is that, How HOT is that) http://www.lightningrodder.com/forum/images/smilies/023.gif

And the way the Coupling expands when it goes WOT is pretty cool too
