Magnuson 112 HH supercharger Category: Accessories
Price: $1
Location (State): VA
Item Condition: Used
Engine: LS2/LS3/LS7/L92/LS9, LS1/LS6
LS Engine?: Fits LS Engine
Was originally a standard 112 unit that was sent back to Magnuson to have the stock rotors swapped out for the new High Helix rotors for better efficiency. At the time they also rebuilt and serviced the rest of the head unit, and put 1:1 rear pullies on. The front has a 2.8 pulley and makes 10 PSI.
Comes with the 90mm throttle body seen in the picture. This is a throttle body that has the top of the IAC housing area machined down in order to mount it upside down, which was required in order for it to clear the hood on an 04 (Note: if installing on a 04 GTO I would recommend buying shorter engine mounts for more hood clearance as it still rubbed mine slightly). Does not come with the TPS or IAC sensors shown. Because the TB is mounted upside down it requires you to route the throttle cable to the drivers side around the rear pullies and in between the blower housing and fuel rail. I fabricated a bracket that bolts to the snout which holds the throttle cable in the needed position, this is included as well.
Comes with 2 BAR MAP sensor seen in the picture, the IAT sensor is not included. During install you re-route your stock IAT sensor so you don't need it.
The bypass valve has less than 500 miles on it, replaced because the old one was damaged, and causing loss of boost at high RPMS.
The inside of the snout was ported to allow better flow from the throttle body.
Comes with 60 lb. fuel injectors shown
An additional pulley was installed onto the front bracket (smaller one in picture) in order to provide more belt wrap around the jackshaft pulley, and reduce belt slip, kit includes two different length belts. I had zero belt slip with these modifications.
Belt tensioner is the Magnuson heavy duty tensioner.
If you are interested in the blower cam I have I will be pulling that out and selling it for $200. Specs are 224/230 .581/.591 114 Dyno pic below for reference.

Not shown is the Magnuson valley cover that is still on the block, it will be included as well as the plastic Maggie intake elbow. The elbow has a hole drilled in it near the throttle body where I had a meth nozzle located. You can plug it if needed.

I would be interested in the TB and valley cover if you wanted to sale them individually.. I bought a tvs 2300 kit yesterday off a guy that was removed from a 2006 gto and of course the valley covers are different... would be willing to throw in my low profile one the the LS2 motor that i have...
