Re: Charger SRT8 engine mods = Challenger SRT8 engine mods
I just bought a book named High-Performance New Hemi Builder's Guide: 2003 to present. It's got some great content on the 5.7 and 6.1 engines including performance mods. Good reading material while I wait on my 09 Chally. Check it out.

We will soon find out though.

Re: Charger SRT8 engine mods = Challenger SRT8 engine mods
On page 36 of the August 2008 issue of Mopar Action Magazine they have a story about how they nuked the half shafts and CV's on their project SRT-8 Magnum and the after market parts they used to replace them.

Re: Charger SRT8 engine mods = Challenger SRT8 engine mods
The horsepower quotes for the Challenger (375 RT, 425 SRT) are at the crank - right? Anyone have an estimate of RWHP?

Re: Charger SRT8 engine mods = Challenger SRT8 engine mods
actually the srt's will make bout 370-390hp at the wheels. It doesnt have as much powertrain loss as the r/t

Re: Charger SRT8 engine mods = Challenger SRT8 engine mods
Most SRT cars with the Predator, CAI, and cat back exhaust make between 390-401 whp on our dyno. I assume the Automatic Challenger will make the same, and the 6 speed manual should show more power to the wheels because of less drivetrain loss.
