Supercharger Selection???
For starters I just purchased a 2001 Coupe (A4, 100,000 miles, basically stock) with the intent of building a nice motor/supercharger setup in the 600hp range. This is all fairly new stuff for me to absorb in comparison to wrenching on carbureted big blocks so please bare with me.
What are the disadvantages to purchasing the largest supercharger and running a larger pulley so that you can just pulley down when needed and it would leave room to grow into with possible future engine mods if need be? I'm basically looking for help picking out a setup, but knowing me I want to leave room so that I don't outgrow the supercharger and have to buy another one.
My other question is I understand the V2 setups are plumbed into the engine's oil pan and the V3 setup has a self-contained oil source. Would it be more beneficial to have a V3 setup that has a self-contained oil source just in case there is a failure of sorts in the blower to prevent any debri from entering the engine's oil or is there a build in filter with the V2s?
Thank you for your time and input.

You can buy the YSi and put a large pulley on it. When you're ready to forge the motor, pulley down and make 1000WHP.
I've heard some say that running a larger pulley on a larger blower makes them run like a dog, but I've seen no midrange losses from going from smaller to larger blowers, only top end gains.
I've never seen anyone hurt their blower and have that material go through the motor and cause problems. The oil fed units can be turned at higher speeds and will last longer according to Vortech.
I'm a dealer for A&A and will be happy to not only sell you the product, but work with you throughout the entire installation process, as needed.
Let me know if I can help.

Listen to this guy he knows his stuff.
If your ever going to want more power buy a larger blower from the get go. No sense in wasting money upgrading. Pulleys are much easier on the wallet to buy.

Anybody know the biggest pulley/lowest boost you can run on a ysi?
I've always heard the same, bigger blower will run like a dog down low if not spun hard enough. I'd be very curious to see a dyno sheet of two similar cars with the same boost, one being a ysi and the other be a si trim to compare graphs and power under the curve.
I have a stock ls6 so I just assumed ysi was too big, but I like doing things the right way and doing them once so maybe a ysi isn't a bad idea even on low boost for a while
Oh and I agree with the others, Bret knows his stuff and is extremely helpful! I didn't even buy a kit from him yet and he's provided better customer service than I could of imagined.

Go with the YSI. I have LS6 with cam and headers 3.8 pulley and OD balancer making 12lbs. With 4" pulley and stock size balancer I would think it would be around 9-10 lbs maybe even less. Not sure what boost would be with stock cam and no headers.

Wow nice numbers. I have a cam and headers too, so change that to a 4" pulley and stock diameter balancer and I might have a winner lol

My motor
1st. Stock bottom,LS1= 7lbs ok but i put a YSi-v3 a&a kit. 12lbs. Sooo, 2nd new motor holds up fine so far 400 c.i. fully forged steel block lq9 on 12lbs with meth tuned carefully to 800 very drivable hp at the wheels. Suggestion build your motor/drivetrain to hold 1100hp, blow it to 800hp. Then have the most reliable fun in your life. Remember it is a power matched system. Not one powerful thing or the weak link will bite you fast.

I'd say 4" pulley and stock diameter balancer to keep boost down and run it if that's the route you want to go. Then you could add meth and pulley down after a month. Then another month later if it starts puffing smoke out the oil filler build a forged bottom end and do 8" balancer and 2.70" pulley with twin pump fuel system and shoot for 1k rwhp!
It's a fun ride and more addictive than drugs or women, but usually costs more too, lol

The first engine I fitted my YSi to when I first fitted an LS motor to my car was a bog standard 5.7 Camaro engine apart from headers and exhaust
I used an 8.25" crank and 4" blower, this netted me around 10psi boost a the top end.
It was fantastic everywhere. Anyone who says the YSi doesnt work on a setup like that is just plain wrong, mine was superb. Mind you it only stayed like that for about 3 weeks before I built a bigger engine and dropped a few pulley sizes lol
Have no fear about going YSi from the start.
