supercharge low mileage stock lt1, weekend driver. Im sure this has been beaten to death over the last 15 years. Heres where im at. I was geting ready to have a cam installed in my car. I will be paying someone to put it in, with parts labor, looking at $1500-2k. I would love to have a supercharger but have read stock lt1s dont last long. My 97 has 37k miles. I see used superchargers online for around 2k. I could probably install that myself. Even at low boost that would make more horsepower than a cam and around the same price. the car will be driven maybe 1500 miles a year. I figure if it last me a few years, i could get a short block built for boost from Carl ellwein for around $5500 then really turn it up. I would prefer boost over a big heads/cam car just for stock drivability. Just a car to cruise in, but when i floor it, i want it to take off!

I believe they all use the same pump. I had an Alcohol Injection Systems for a year, then switched to the Devils Own setup. No problems with either one, but Devile own has a fitting that installs in the washer fluid tank without having to access the inside of the tank.

I'm planning the same and only wanting ~400hp/400tq to be highly useful at autocross and fun on the street. Game plan is meth kit with no intercooler etc to save on complexity/piping.

I'm just scratching the surface on the idea of PD blowers. Much to learn and figure out.

I'm purposely only shooting for 400 at the wheels. So next step is to properly size a blower that will work for me. I'm not one to chase HP numbers on a dyno. I know the rear end/clutch and stock motor will get upset real quick. I may get a slightly large blower to keep it from working too hard = less heat and still have room to grow with a new motor build. Going to be a long project, but so far it's looking feasible.

Around 6-7 psi is fine on a stock engine as long as the tune is good, you have plenty of fuel and some sort of charge cooler.
This should go without saying, but a set of coated long tubes and full exhaust should be considered compulsory with a supercharger install. You'll need a set of ~42lb injectors also. A small cam and the requisite valvetrain upgrades typically yields an easy 470-500rwhp on a safe tune when paired with a blower.
How long it will last depends a lot on how you drive and maintain it. Obviously, maintenance is important with any supercharged or extensively modded car. You can definitely have some fun in how you drive it, but if it's constantly flogged (particularly in hot weather) it will have a significantly shorter life.
I know people who blew their stock LT1s with boost in less than 2 months, and I also know a couple whose motors have lived for 10 years or more with boost. None have been daily drivers.
