Awesome!! As you give it more boost it will bring the power curve down in the RPM range. Do you know what size pulley you have?

Let's hear some idle clips!

I'm using the stock Lsa blower pulley and stock truck balancer
Here is a short clip

Holy crap that is pretty cool. The process to make an LSA unit work hardly seems worth it, but very cool none the less.

The swap wasn't that bad actually. With the cam, springs, headers, exhaust, supercharger and tune I came in at about $3200. I'd say that's a helluva deal.

Wow... That's amazing actually. I can't believe you pulled it off that cheap. Care to share a complete parts list and how you set the pulley's up?

It sounds pretty good too! Awesome! Mild but it's definitely there!

Post your dyno chart of you can.

I don't have a dyno sheet yet, but will post it when I get it. Tomorrow I will compile a parts list and mods I had to do to get it to work

I found a 6 rib blower pulley 2.40" that will get more boost from it when your ready

What did you put on it for exhaust? What size pipes and mufflers?

The headers have 1 3/4" primaries and 3" collectors. I got them from speed engineering, they are for 07-13 1500s, but they fit the 2015 2500hd with no modifications. The rest of the exhaust is custom built. It's 3" out of the headers and y into a 4" single exhaust. Uses a 4" magnaflow muffler, mandrel bent over the axle w/ a 5" double wall tip.
