Supercharge my 5.3L?

[chippedchevy]

I have all the bolt on upgrades (throttle body spacer, Flowmasters, race cats, Air Raid intake, Comp Cam, Superchips programmer) and I am debating spending $5k on a supercharger for my Z71. It has 105K. It is a nice truck that is maintained very well...but idk if it can handle it at this point in it's existance. What do you think?

The cam might throw a wrench into things unless you plan on getting a custom tune. People often worry about adding a supercharger to a high-mileage engine, but if you put it on the truck when it was new, would you not expect the engine to last to 100,000 miles?

Thanks...the place that put the cam in does custom tuning. I have another long block for it so I have a back up plan. The only reason I love this truck is it was one of those trucks that is just factory fast. It was put together right or the stars were aligned when it rolled off the line cause it has always run a little faster than other Silverado's at the mud drags.

I think you should be ok since you have a tuner and you can control knock-retard which is really the only thing you should have to worry about with boost. The only thing that would suck is if you were knocking like crazy after dumping $5k on the SC and you would have nowhere to go. But with all the extra flow with the cam, exhaust, etc. heat should not be and issue and any knock you may encounter should easily be controlled with some added fuel.
