Where would I be able to find a mp112 1:1 setup for my 06 GTO? I was looking on the Magnuson site but didn't see it. Also, how much does it usually cost to change over?

Magnuson sold all their inventory to superchargersonline dot com. Try giving them a call and see if they have any left. They are the 3" 8 rib rears from the stock corvette setup. I did it myself, you need to have access to a press and be careful not to crack the rear case taking them off. I think they were about $200 for the pulleys.

Magnuson did not sell all of their inventory to Superchargers online. SO is a dealer
I when I talked to Magnuson 3 weeks ago regarding a 112 pulley that is what the sales person told me. They then gave me SO's number and told me to call them.

Edit: I was talking about only the inventory of the older MP and TVS stuff.

IMO, I would go with a TVS as I am guessing you will get a warranty. I doubt that is available for any of the old MP's. If you decide to go with a MP makes sure it is compatible. It is different for the 04's then the one for 05-06.

SO has what I need for the 1:1 setup. Thank you guys for the help! While I am at it is there a better setup for fuel than the boost a pump? Maybe a higher flow factory replacement?

If your serious about a Maggie. I have a very VERY low mileage 2.3L sitting on the shelf at home. Has a whole lot of "gooder" parts to go with it. I'm not giving it away, but it is 25% off the going rate for a NIB one.

Just a thought. PM me if you have any interest. It WILL work on an 04 LS1. I've done it. With a cam, headers, and a good calibration it'll put 600 to the wheels. Mine peaked at 598 at 4000ft elevation on 91 pump fuel.

Don't waste your money. Sell the 112, get any of the vastly superior superchargers that are out there.

Even though I still run a 112, and get crazy power out of it, Ive done pretty much everything possible to push it to the absolute limit over the years. That being said, If I was starting over I would go with a different blower. Not that you cant make 500-550+whp with a 112 on an LS2, it just takes more work.

You can get a Deatschwerks or Aeromotive drop in that will flow more than stock. If you need more than that you can get a Magnuson fuel regulator from a truck kit that mounts on the maggie rail and is return style instead of a dead head. Then delete evap and use the hard line as a return and add a second boost referenced walbro in the bucket and you have a pretty decent return style system using OEM quality parts that will support quite a bit more HP. That's what I have on my E85 setup and been 100% issue free for over 5 years at 560whp.

Amen to that. I love stories like this. I've taken a 2.9L Whipple about as far as it can go on an engine I'm working on presently. Were in the 1200 range for rwhp.

Honestly now its just turned into a personal challenge to see how much power I can make with this little guy. We've been through a lot together lol.

I would love to do a LSA or TVS supercharger but, being a single full custody dad it's just not in the budget anytime soon. Right now I just want to make a little more than what I am preferably with out creating pieces. I bought this GTO with the 112 on for a decent price but, I have body work to do too. Maybe in a few years I can do something a little crazier. I appreciate all the feedback!

I know this post is about a year old, but I'm in the same situation. Just trying to push the lil heatbox to the limit. So far I'm at 560rwhp on 93/Meth. Plan on putting in a electric water pump tomorrow and getting a new tune. Car is tuned way too rich

Why not swap the rear pulleys for overdrive, then use a large front pully to slow it down and get better belt grip. that's what I did years ago. Add an Active Interchiller and you're golden.
