    Default Whipple Supercharger Kit

    It's final, i'm going to bite the bullet and invest in the Whipple Supercharger. I've contacted Whipple, and they are going to be releasing a new kit in 60-90 days, here's the email i got back.

    We are working on our new intercooled kit for the 99-02 4.8/5.3/6.0 motors. We are about 60-90 days away from releasing the kit.

    You will pick up about 60-65% more HP and Torque. The kit will retail for $6299.99 plus freight

    So, what i'm asking is, with getting a supercharger on an engine with 128k miles on it. What will be needed? Rollers? Valve springs? What i am planning on doing is to get a Cam shaft, and new springs at the same time as the supercharger. Should i just go the whole nine yards and get new rollers, and new rocker arms?

    I'm going to be getting the kit in a couple months, so i might as well start looking at what i'll need.

    Personally if I was going to invest 7k+ into an engine I would rebuild EVERYTHING, do it right the first time and save more time and money down the road..keep us updated it sounds like its going to be a beast

    Buy a builder block,that way you can play right away and learn all the tuning on the o.e. block and get the most out of the built motor later

    What is the difference between the new kit and the current kit, other than the intercooler? Seems pricey.

    As Jenna said that seems a little steep, the ATI kit was a little less power, but a good $1000 or so less.

    And as the others said, if you're looking at doing a supercharger, *and* want to get best power out of it, I would also suggest spending $$ on your engine first. Either start with a good low mileage short block or from scratch, make sure you've got a good enough rotating assembly to handle the power.

    Force induction benefits from larger cam built for forced induction, ported heads or higher flowing heads, roller rockers, intake manifold, headers, larger throttle body, larger injectors. Most of this stuff can be had for $4k or less, depending on deals, what all you replace, and how extreme you want to go.

    Now if you were only going to do cam, springs and rockers, I'd probably save the money on cam/springs and just do the rockers, with a slightly higher ratio. Stock cams/springs should be able to handle next higher level rockers without bind. If you're worried about your springs change them too then. Without upgrading your heads/intake/exhaust you won't enough benefit from doing a cam swap to make it worthwhile. Roller Rockers are an easy bolt on though and worth doing for most any engine.

    Would it be better for me to find a low mileage 6.0l? If i'm going to do an engine swap i might as well make it worth it eh? But here's what i'm thinking now. Being in a couple months, the prices of Duramax trucks are going to be a lot lower then they are now, all the 2011 vehicles are going to be coming out, killing resale on the older duramax trucks. I'm going to be needing a diesel for this winter, i'm just thinking about the money, i was planning on keeping this truck to be my toy, but money is money i'm sure everyone knows that. Having payments on a new duramax will hurt the wallet.

    Rebuild the whole thing. That way you can beef up the bottom half and crank up the boost to 10lbs!!!!

    Make sure the block isn't aluminum and try and get a kenne bell and you can push it up to 13lbs or more. For sure you do a complete build and don't forget to get a bigger alterntor pulley so you dont over spin it
