I have a year warranty from canadian superchargers.com and it is a stock pulley. I am actually replacing it today (if the stock pulley cooperates and comes off) I have a new tool to hold the pulley in place while i torque the bolt off the pulley.

The rest of us Series 1 guys are really interested in how that sucker fights! I've got a good strap wrench. I'm hoping that'* enough to hold it. Keep us updated.

Not a bad idea. I was actually going to make a wrench or socket to hold the pulley hex portion, and use a socket inside it for the nut. I may take a crack at this before my pulley gets here just for fun. Having all the air tools is a big advantage.

Hey I finally finished everything on my car. The timing chain is all set and I got a good pic of the inside. Hopefully it comes out as good as I took it. Also, I got that pulley off finally. It took some persistance and team work. I got the correct size socket and my dad used an oil filter wrench and cloth to hold the pulley in place and I just muslced it off. I started thinking that thing would never come off. The new pulley went on fairly smoothly but needed to be wrapped in electrical tape to cushion the metal oil filter wrench from biting into the aluminum pulley. It worked out fine. The old belt actually fit on there great and plenty of tension. I tried to fit a smaller belt on but it was too short. I actually thought the smaller belt wasnt going to be small enough but hey, I can go return that smaller belt and get my 27 bucks back.

Anyways everything works great and feels good. My boost gauge actually pegs out past the 10 psi. So I know I am getting at least over 10 pounds of boost. If you have any questions ask me!

So you went from a 2.8 stock to a 2.5". That'* a ratio of 1.12.

If I went from the 2.55 to a 2.2", I'd get a ratio of 1.15, very similar.
If I went from the 2.55 to a 2.0", I'd get a ratio of 1.275.

How much boost did you GAIN? About a pound? Maybe more? I know it'* hard to tell when you're off the scale (my water injection does that WITHOUT alcohol), but take a guess.

JSeabert measured his crank pulley yesterday when he changed his water pump, and said it was 7.25". I'm trying to figure out the ratios for the best combination, without getting into heat loss.

My water injection IS going. Has been for some time. I just don't run it in the winter.

The heat problem would be better solved with an intercooler or a couple other ways. Water injection is far more dangerous than you think. Yes, it works, and has other benefits besides intake cooling, but is it worth it? I'll finish up my alcohol testing, but then it gets replaced by an intercooler. Far more efficient, no danger, and it'll look cool in my signature.
