Superchargers and power

Recommended Posts

So i know that the 99 body style is similar up through like 08, however i wanna see if the 5.3l is the same throughout, im looking at one that specifies 04-06 and im wondering if theres a huge difference to deter me from purchasing and using it

 

 

Im also curious at how to generally create power, my engine compartment is bone stock outside of a k&n air filter, partially cause thats how i bought it and partially because im a beginner and im a little nervous about ruining it as it is my daily, however im coming into some money and am going to purchase a new daily and turn this into more of a project

 

Thanks for the help in advance

Wrecking yards or places like LKQ will labeled an engine or whatever as fitting specific years because it may be based on the VIN number. Like that specific engine was only offered in the 2004-2006 model year, so technically it's suppose to fit just those years for a drop in and go unit.

 

Now in reality, that 5.3 or pretty much any 5.3 from 1999-2007 will bolt right into your truck. The long block, crank/cam sensors, knock sensors etc etc are all in the same exact place. The newer the engine is the more power they made based on small changes to piston design, cylinder heads, injector size and calibration changes.

 

Your 1999 model year truck makes the least amount of horsepower of the 5.3's, comes with the territory of being a first year truck.

 

So for example, say you bought that engine and it was for a 2006 truck. You drop that engine in with everything else it came with it. Intake to oil pan plug and play type deal. Then if the computers calibration was updated by someone that knew what they were doing it should be the same power as the 2006 truck was rated for. It would be like going from 285hp to 310-315hp if I'm getting my numbers correct.

 

 

There is nothing wrong with starting off with the stock 5.3 your truck came with. You can remove/add parts to that and make more horsepower without swapping engines. It just all depends on your goals for power and the size of your wallet. Of course knowing what you are doing comes into play too, won't exactly be easy if you don't have a full grasp on the LS based platforms.

      Anyone see this? I emailed their sales and was told 6-8 weeks for release.  Very interested in seeing what's included and what they're doing for ECU tuning.

      My dad passed away in march, i am keeping his truck. He bought it new and loved it to death. it is a 2008 1500 ext cab. It has 78,000 original miles, 2 wheel drive. I live in pennsylvania and he stored it every winter so it never saw salt (big deal for up here). He didn't want to go over board with it in fear of ruining it. so all that's down is a superchips program, flowmaster exhaust and k&n cai. I was thinking about taking it a bit further and dropping a supercharger kit from summit, borla exhaust, and lowering kit. I have never really hot rodded a truck, nor do i have the cash flow to go nuts. I was just thinking something he would of liked but not overboard. I was wondering if anyone has done this, and what did they think.

      This is a brand new 2.8 inch (71.12 mm) 6-rib pulley that I have to take a loss on. I installed it, turned on the engine, threw the belt, and realized that the offset was wrong for my blower (which meant this pulley stuck out too far and misaligned my belt). Oh well, can't dwell over it, just gotta sell it. So yes, this pulley has ZERO miles on it.

      If you don't know about GripTec pulleys, here is the link to the one I am selling. Basically, the ribs and grooves are roughed up like sandpaper so there is less belt slip, less knock, and more boost.

      Hello All, 
      I got my truck back from the shop after having the supercharger put on and when I totally pin the throttle I hear a loud squealing noise from mid cabin.  The supercharger whine is awesome but gets drowned out by the squeal under full throttle. I had a truck before make that noise when the exhaust I put on was not clamped down right. It made me think of the flapper valve in the GM Borla exhaust I have and was wondering if that could be it. Its in the same area I hear the noise? The tune took off the cylinder deactivation so I no longer need the flapper. Any suggestions on the flapper? I was going to tack weld it open but wasn't sure if that would stop the noise and also thought about cutting out that piece of pipe and welding in a new piece. 
      Any suggestions?
       
      I know [mention=118595]1SLOW1500[/mention] has dealt with several modded trucks. What do you think?

      I've got a 2015 sierra slt 4x4 with a P1X procharger setup on it and I'm currently running NGK 6510 iridium spark plugs. I'm constantly having issues out of the spark plugs when I build boost it starts missing, the boost is blowing the spark off the plugs a little causing it to miss on the top end because it isnt grounding out properly. Just looking for a good copper/nickel plug recommendation around the same heat range that mine are, I'm tired of these plugs and can't seem to find any that will work. Thanks!
