Super/pro charger kits??

[jay07]

Is there such thing as a supercharged 5.3?? GXP or pro charger?? If so where?? , All I ever see is the cartunning turbo kit...

Why? Turbo is better.

[SgtMarshal]

there have been a few LS4 vehicles supercharged, but it's all custom. and turbo isn't always better, it just depends on what you want to do.

A few?

Pretty sure I've only ran across one.

The guy tossed an LSA blower on it and relocated the PS fluid tank.

Any turbo kit is going to be better than tossing a parasitic blower on it.

Get a built transmission first that can handle it; then go from there. Best path possible.

It as been only one supercharged ls4 in existence. It's not as simple as tossing a lsa blower as the rotor pack was completely flipped around to the other side machined the housing and had to re mount all the bbv stuff and various other things to get it to work. A regular lsa will not even sit without hitting the alternator bracket the water pump ps pump and reovoir bracket

Turbo kit offered on the market is far superior. Comes with everything you need to make it work in pump gas and still have 440 to 500whp still on a simple valve spring upgrade. There reliable and gone several years with no harm on daily drivers.

Turbos break. Blowers don't. Go ahead and argue with me, but I used to work for Ford, where basically everything is turbocharged now. I had customers lose engines at 20K miles.

Lmao, blowers dont break...right. so theres no reason that couples should be sold or bearing replacements or the like then huh? Losing engines is irrelevant. Get a clue.

[bandook]

Seems that guy just likes resurrecting old threads and giving bad advice. Dunno what his problem is. He "used to" work at Ford. Lol. I can only speculate why he doesn't still.

Tossing out absolutes to poison the well in favor of either power-adder type is only showing bias and ignorance.

Having now owned both setups, and built dozens more of all types, I can say there's valid reasons go have either... and this discussion has been had 1,000 times before, so ignoring those points is living in a bubble.

Superchargers that GM has installed are very reliable, and the minimal coupler maintenance after 100+k is only necessary to reduce the noise from chatter that's only harming coating on the rotors. We've dismantled many of these, and the engines underneath don't suffer, and continue to build normal boost, as well. The parasitic loss is simply the cost of adding way more power than it requires to boost (similar to requiring an X-ray to see a broken bone, you get a small dose of radiation, but it's for the greater good of your health... and you're better off for having it).

Turbos don't exactly live in a vacuum, and if you put a hot-side in-line with your exhaust, and didn't route the charge pipe to your intake, you better believe there'd be a noticeable drain on your power. It's not a directly observable or measurable thing, so it's not discussed, and the understanding of the pressurized piping is easier to comprehend for most. Boost numbers are easier to adjust without having to do more engine work, so many convinced themselves that it's the Holy Grail, despite not building past the point that a supercharger can also achieve.

There have only been 5-10 setups built for cars in this genre that have gone past the point of our daily driver street builds, mostly using turbos, and mostly being all-out drag car setups (or configured that way for their track/dyno runs).

TL/DR - build whatever you can afford, what you want, and what will make you enjoy your car's performance the most. Enough thought and effort put into any upgrade path will make you outperform 90% of the people online, and 99% of the people on the street, if that's your goal. Mine is to simply enjoy turning the key and hitting the gas. YMMV
