papi Posted October 19, 2002 Report Share Posted October 19, 2002 I was wondring if any one had any information on a thunder package for a silverado. I was reading an article in Sport truck magazine and they featured a silverado with a whipple supercharger and other mods. total horsepower was 448 . the article mention it was offered through Courtesy chevrolet they even include a stock number (12177). however they do not include any phone number or address. Has any one ever heard of this package it sounds to me like a dealer ss. Link to comment Share on other sites More sharing options...
dcairns Posted October 19, 2002 Report Share Posted October 19, 2002 Here is the webpage I found a while back. I don't know if they still make them as it is missing some pics. They are located in Phoenix, Arizona (800) 555-9322 They do sevral vehicles this way http://www.gmperformancecenter.com/ Silverado 1500 page http://www.gmperformancecenter.com/silverado.html Home page of Courtesy Chevrolet http://www.houseofcourtesy.com/home.htm Here is their list of modifications: WhippleSupercharger exhaust system Engine Management upgrades Air Induciton systems Suspension compents Tire/wheel packages Custom front grill cowl hood carbon fiber/ burl wood das DVD/GPS ?gamestations, etc Front air dams They claim 450HP from what I assume to be the 5.3 liter engine In the end, the only thing special about it is the fact that you can buy it all done for you. All the mods are readily available for you to make on your own. The more important features might revolve around price and warranty support.

ozark66 Posted October 19, 2002 Report Share Posted October 19, 2002 i've been to the dealer. pretty classy org. They know what they are doing, and will prob. do anything to the SS you ask for. They also are able to keep the mfg. waranty Price may be an issue, however, in Phoenix the disposable income is slightly higher than other places. They charge it because they can get it. Typicallythe thunder pkg. also included different badging/graphics....prob would not do that to the SS. Link to comment Share on other sites More sharing options...
