    Hey, I wanted to reach out regarding installation of a Whipple 2.9L on my 2009 SRT8 6.1L. It is making a knocking sound when I started it up. Now, I will tell you it is colder than all get out in Indiana right now. I warmed up my garage to 40deg before starting.

    I got a hold of Mike Mailcoat at Whipple and he said, "Ahh it sounds like a normal Hemi." Its due to the single belt drive.

    don't know how much is safe for a stock 6.1. I do know it adds a pound of boost. you'd have to talk to your tuner for the added pound of boost.

    6.1 hemi 2008 srt8 challenger and not sure how much boost I'm pushing I'm guessing I have just the stock pullers my supercharger came with ? I bought my car like that already that's why so I'm guessing 5-6 psi?

    Hey Andy
    Did you have to modify your hood for the pulley? I had to for my R/T. I order the new srt hood for my r/t today and I'm curious if I need to modify the new hood.
