    Silverado 100 Horsepower Performance gain on a budget

    Silverado 100 Horsepower Performance gain on a budget


    Are you looking to make 322 horsepower to the wheels on a budget?

    Test Vehicle: 2006 Silverado 5.3L regcab 2wd

    Baseline HP: 224hp

    Final HP: 322HP , 300TQ

    Our test vehicle is a 2006 Silverado donated by Jacob of San Antonio, TX.

    We all know how it starts, you bolt on a few simple modifications and before you know it, you have the performance bug, this Silvervado is no exception.

    The first series of mods consisted of bolting on a set of Pacesetter headers, along with a 40 series Flowmaster.

    The installation was soon complete with a StageII cam package from Nelson Performance. The custom grind features a healthy 220 duration and .588 lift.
    So you want a 100 extra horsepower from your Silverado, here is a list of proven components.

    Pacesetter headers and ypipe: $400

    Custom cam kit: $690

    Performance tune: $375

    Flowmaster muffler: $50

    Installation will vary.

    Here are the results of our performance upgrades.



    Installation and dyno tuning provided by Nelson Performance, San Antonio, TX.

    thanks, you'll notice very similar results from the 4.8L, just a tad less torque, nothing a nice converter won't fix.

    Wow, 98 hp to the wheels with just those few mods??? Good article! Nice addition to the site. It's almost like we have our own LS1 Truck magazine...

    If you could make a reasonable estimate based on the mods that are listed in my sig, what RWHP I am making?

    Keep in mind, every truck is a little different and some are just strong from the factory.

    I'd guess right around 300rwhp is what your truck would lay down, anymore would surprise me, but 300hp is a lot for what you have done.

    get it on the dyno and let us know,

    Sounds about right from what I have heard from others... Yeah, I will get it on the dyno soon. I am pretty much done with the mods for the time being. But it will get heads, a Radix, and meth before the end of the year... Thanks for the reply!

    I knew I really need to get my truck tuned when I went to the track this past weekend, and ran only a few tenths faster than a fully stock, 5.3L-powered RCSB (a buddy's stepside p-up). Once I fix the trans, I'll re-evaluate my loose cash, and move the priority up for a tune.
