If anyone is condsidering upgrading their 112 radix to the 122, here are the details:
The cost will be $2306.00 plus shipping this includes the "new" 122HH silver supercharger with the pulley of your choice, new manifold lid, 60lb injectors, 90mm J-tube(inlet) and 90mm gasket (o-ring). We will also clean and inspect the intercooler, replace all the seals and gaskets. Your old 112 supercharger is yours to keep and sell.

Call 877-886-0842 and ask for David.

 

what kind of gains are typical going from a 112 to a 122? Is a tuning included in that price?

 

Wow! I wish I had the cubes to support that beast. Killer deal!

 

Is a 5.3L too small to support the 122HH?

 

I would not suggest the MP122 for a stock 5.3L.

 

So is this box 1 ??
the words
"Clean and inspect intercooler,replace all seals and gaskets" confuse me?Do we send ours in?and you ship back the left over parts?

 

Upgrade means, you send in your old blower and get a new MP122HH back.

 

Oh ... so what of the 112 can be kept and sold?

 

Affirmative, you receive your old MP112 HEAD UNIT back.

 

Sorry for all the questions but if we want to sell the head unit after the upgrade, what will the buyer have to buy to install it? Box 2 and anything else? What is the cost of the additional items to make the 112 usable again? I just want to be clear for any potential buyers. Thanks.
