    My 2003 Escalade XS-500 Done at last!

    XS 500 engine Bay.jpg

    Well its all Done! Took me four months to get everything right, but its done. Thanks to everyone who chimed in, especially jjtwomey. I had the Supercharger rebuilt with upgraded bearings, and an aftermarket billet impeller. Went from 7 to almost 9lbs boost. Had a tensioner made, and while I had the front apart, changed the water pump, ac belt, blah blah. I took off the recirculating valve, and put on a blow-off valve. Now I get that WHOOSH when I let off at high RPM, also the charger whines, so its no sleeper anymore. Not a big deal to me, just happy to have it back to its full Throw you back in your seat potential. I know the engine bay is dirty, I will get that cleaned up. just so glad to be done.

    I will try to get a video of 0-60. The Blow off Valve is hardly ever used, being an automatic, but its cool when it does. I am guessing thats why I can get away with using it, without setting off the Mass Air Flow sensor.

    Great looking truck! What year is it? Does that xs 500 come from the factory or is that all mods you did yourself? I never seen or heard of one until now. I love my escalade but I would love it even more with 500 ponys

    Thanks man, its a 2003. I have 115000 miles on it. The XS-500 was a factory option. If you google it, there is more detail. Mine came with the engine mods, (Supercharger, upgraded fuel pump, bigger injectors,) The dual exhaust, bigger brakes, and a few cosmetic touches. Retailed new for almost $100,000.00. I did not know much about these until I found this one. The guy I bought it from had no clue either. That helped me out. I went from 7lbs factory boost, to almost 9lbs, so I should be making in excess of the factory 522 horsepower.

    When upgrades are added anything can be possible on parts

    From the back it looks black but you can clearly tell from the front its the forest green color they made idk the exact name of it but it is indeed rare to find i look on autotrader every month or so to see whats out there for colors and price and found that the green and the cherry red also cant remember the exact name are the hardest colors to find. They made another red too but it looks like a fire engine red in my opinion i think its ugly

    I hate the red, not to bash those who like it. I always thought I would want Black or white. Did not even realize there was a green. When I saw it, I was not crazy about the color, but it grew on me, and I like that there are not 10 in my town that look just like mine. I have also seen one that is a dark Blue. not sure if it was a factory color though.

    Also red makes it a target for theft (higher insurance cost as a result)
