The bolt on kit is complete and will start you out with ~5lbs boost. No other mods are needed.

wow i know you from pt.net im rather shocked that you dont know better
on our stock trucks the best he will see out of a 112 is 8-9 i have one i know
and the 122only comes in high helix and is a 4 lobe compressor. please do more research so you dont confuse this guy and kill my sell
if i am wrong I will chock it up to old age but I am pretty sure the TVS (Gen VI) is 4 lobe and the gen V (112/122) is only 3 lobe but I will check with Magnuson in the morning for ya.

Maybe you should do some research of your ownby the way let me reiterate I am making 10+lbs with a 3" pulley. I lost boost freeing up the exhaust with headers.
negative, the MP122HH is considered an evolution of the 5th gen if I'm not mistaken, a high helix 3 lobe setup displacing 2.0L. The R1900 1.9L is of the newest designs (6 gen I believe), 4 lobe, even higher helix

about the lobes? A supercharger is nothing more than an air compressor, shoving air into your manifold/cylinders. A 112 compressor is good for an engine up to and including 6.0, anything larger should go with the 122 or a Gen VI TVS unit of which there are 2, the 1900 and 2300.
I have a 112 and do just fine with it, probably pushing it just past it's peak efficiency range but it works to push my 5300lb truck into the mid 11's.

If anything he is helping your sell. Why buy a 122 for more money when he can buy your 112 (polished) and get pretty much the same boost out of it. I was personally involved in taking a 112 off and putting a 122 on and that truck (6.0L) didn't gain any boost. Yeah yeah, he changed cams, but unless you can get a 122 for the same price or cheaper...I'd just do a 112. You can almost get a better deal on a 112. Just my 4cents.

Trever1t is correct, they are both high helix but the MP122 is 3 lobe 60 degree and the TVS is 4 lobe. They didn't go 4 lobe until the TVS.

Well, like it is mentioned below, with the supporting mods, you can achieve over 500+ hp. But you will need a smaller pulley, a meth kit, cam, valvetrain, properly sized injectors, etc. It isn't a horrible idea if you had your stock heads cleaned up and had a 5-angle valve job done. When you spec your cam, make sure it is slightly intake biased--(for a 5.3L) something like a 220/218 .581/.563 115 LSA. I am by no means a cam spec pro, but something in that range is what I would spec for my own truck.
Yeah, Jason's truck is very reliable and with his 3.42 gears, he does get decent mpgs on the highway...
