I've had the smaller pulley on for awhile, pretty much as soon as they came out with it. On the gauge it shows about 3lbs more boost wound out and shows the boost coming on at a much lower rpm. This is a 3.6 manual btw. In the seat of the pants you do feel a difference and worth the few bucks. As for changing the pulley, it's pretty easy. Just use a puller and it takes about a minute.Quote:

No sound bytes, don't have'm. Wrench? I didn't think I would have to go from beginning to end here. Nuts and bolts is all but if you really need the details then an impact wrench is a must. Spin the nut off. Put the puller on and crank it to until the pulley comes off. Carefully tap the pulley down with a piece of wood and use a thread locker when u re-torque the nut. Re-install and possibly reprogram. It's that simple. Now if you want to get really crazy install a catch can too. You won't believe the amount of oil you get going into your intake. The catch can install will probably take longer to do. Good luckQuote:

I hope you mean to use 2 separate catch cans: one for each hose. Definitely don't want to run both hoses through one shared catch can, or else you'll have a vacuum (and boost) leak and won't be drawing fresh air through the crankcase.Quote:

Anyway, the double catch can I think would be excessive and more hoses. I'm not happy now with the cob web around the motor. As for the plumbing in is pretty simple. I believe somewhere in these forums is what I used as a diagram. I should probably post a pick because I didn't put mine where most put their can. Mines in the front beside the alternator. If I wasn't ashamed of my hosing I probably wouldQuote:

Only about 40 hp more than the stock Pentastar, and substantially less than a supercharged Pentastar. That would be a $20k downgrade from a supercharged Pentastar. If you're going to do a V8 conversion, go for a 6.2 LS or 6.4 Hemi.Quote:

Let's just say if the 3lbs of boost makes it blow than the 2 door jeep is gone and a 4 door will show up in the garage.....which isn't cheaper but damn at this point stock and untouched would be less stressful.Quote:

You already took the plunge with the blower. You'll be ok with the smaller pulley. But then again I am the guy who overtightens everything till it breaks so what do I know. Go for it. Thank me laterQuote:
