    I was saying that because we had to change both the serpentine belts and the supercharger belt in my bros 96 Riviera. Getting the belts off was easy. rethreading all the belts on the other hand was a different matter and it took 2 days to re thread both belts. Thats what i meant by my statement. the pulley changes are not that bad but the belts can pose a challenge

    The problem on the Riviera is the belt goes around the engine mount, meaning you have to remove the mount and prop up the engine to get the belt out. Engineers...

    My 00' GTP has ran a best of 12.48 at 112mph. Should be able to push it to 11.9's this year with the new heads, cam and GENV m90.
    Yes check out Intense and 3800pro.com
    There is alot of power to be had from the L67/L32, especially in a 3600 lb car, 4 door at that. Surprises alot of people.

    Lot's of help here... www.regalgs.org

    Just dropping the pulley size to get more boost is not the best thing to do without the supporting mods. More air in means you have to get more air out. Without upgrading your exhaust your just boost stacking and that is hard on your engine. Get a good custom tune as well and scan for knock retard.

    I have seen a 3.8 pulley car go faster than a 3.4 pulley car simply because of the supporting mods.
    Do the CAI, headers and full exhaust, get a custom tune and then look going to a 3.4 pulley.

    Check out the regal forum if you have not already lot's of good stuff there.

    So I have a 2004 MC Supercharged Dale Jr signature series and I’m wondering if anyone knows how I can get the cluster gauges to work.
