LSA blower on a 5.3?
My 2 biggest issues with the swap is that the stock injectors are worthless if your doing any mods to the setup. Aftermarket injectors are very limited and basically there are 2 options. 80# deautchworks @ $450 or ID850's @ $850+.
My other complaint is since s/c go into boost off idle, the mpg's on these, basically suck. I sold off any my stuff, and am going to finish my turbo build where I can buy $300 injectors, and still get 20+mpg's, oh, and also be able to turn up the boost to make more power.

I'll be into my new not used supercharger swap for about $3,000-$3,800 but it is going on an LY6 6.0 so no adapters needed. I have less than $700 in my 18,000 mile engine/trans but I also stumbled onto a hell of a deal. The same motor would cost you $1500 and up so it does add quite a bit to the cost and the fact that with the adapters he won't be pulling the engine he already has.
To anyone buying these superchargers don't forget why GM is replacing the whole supercharger and not just replacing the failing coupler, When the couplers fail they wear the shaft on the supercharger and the metal from the shaft end up contaminating the supercharger bearing and the bearing will eventually fail. You might get lucking and get one that hasn't had the chance to cause any damage but that's the chance you're going to take.
You will also want to price everything needed because the supercharger itself is only a small part of the cost. I paid $1475 for a new supercharger with fuel rails/injectors/sensors/bypass valve and $387 for a new ZL1 lid. The rest of the money is all the stuff needed to make it all work. Just the supercharger/accessory drive is going to run you anywhere from $800-$1500 depending on what you use. Choose carefully because there are some systems on the market that are poorly designed and you'll likely end up with belt slip. I'm going to use a combination of stock CTS-V supercharger drive and corvette A/C bracket and Holley corvette alt/ps setup.

But it is all fun. Just trying to understand.

As far as gas mileage is concerned they are only slightly less efficient than a turbo motor. The 2016 CTS-V (640hp) is rated at 14-19 and weighs 4,200lbs and my extended cab Silverado with a 4.8 (285hp)only weighs 200lbs more and still only rated at 14-19mpg. I'd say for the power the CTS-V is making the gas mileage is pretty damn good and it idles smooth as a babies butt.

Of course I would rather have a turbo.....but too much fab work for me.
On the MPGs, I have a Tahoe with a 5.3. The computer says it averages 14.4 mpg. I also have a Silverado with a 6.2 with a TVS1900 on top. The computer says it gets 15.5 mpg. You definitely don't need as much throttle to get going in the truck, so maybe that's it.
On the LSA setup......for trucks and SUVs, I think the air snout would collide with the alternator. Otherwise my truck would have a Whipple 2.9.

What guy?
Gotta link?
In a config with the alternator down low, I can understand.
But in truck/suv form with the alternator up high, the alternator would have to be moved probably about two inches to the right.
