I wanted to put some info out there in order to help all who decide to go with the Gen3. Vmp does have a short video of them drilling out the coolant tower bolt and putting the blower on, but I wanted to aid those who may be doing their first blower swap and need further details.
The Gen3 has similarities of the gen2r but there are a few differences that are worth noting on the install.
After unpacking blower from box/plastic and verifying you have all your install pieces.... install the blower pulley, egr studs with gasket and the evap sensor (11-14 cars). Transfer your factory dowel pins from previous Supercharger to same holes. If you are using your factory fuel rails, you will need to get your dremel out. I found out after the blower was fully installed, that my passenger side rear fuel rail bolt would not line up in its hole. The egr mount on the blower case hangs over this bolt preventing you from being able to thread the bolt in. You will need to dremel about a 1/4 inch off the corner (see picture) in order to get your bolt in. Insure that you have the bottom and inlet of blower covered/protected from any possible shavings.
If you did not loosen your egr tube (at egr and on header primary, do so at this time. Loose both ends, not disconnect.)
Next if you did not already remove your current blower and there’s enough room to drill the housing, attempt to do so before removing current Supercharger. If you have already pulled the blower make sure your lower intake manifold is securely covered with duct tape or plastic to insure no metal shards get in it. Remove the coolant tower bolt like instructed in VMP video and then proceed to drill out the hole/tower down till you’ve reached proper height between lines on drill bit. Here you will find that the drill bit left a outer shell around the perimeter of the hole that you will need to dremel out and grind off/down. Make sure all edges are smoothed over and clear completely on front and backside of tower, you will need all that space for the front of the blower to clear.
Clean up mess best you can(vacuum) and with help of someone else verify the blower is going to clear the tower prior to removing your tape/plastic barrier.
If clearance is good remove your barrier and fully clean up metal shavings.
Lower blower on top of lower intake but not all the way back. At this point connect both boost bypass lines and the 90 degree hose, make sure you left the furthest rear left bolt - I used factory bolt here.... VMP DOES INCLUDE A BRASS BOLT- (looking from front of engine) installed loosely. The blower is notched to slide around the bolt ....at this same time you are doing that line up the egr studs with the egr holes and slide blower in to place. Insure the blower seats correctly with the factory dowels. Using your supplied Allen head Supercharger hardware, start each bolt a couple threads till you have all bolts in place. Tighten them down a little at a time working your way front to back on the blower. Once you’ve got them snug, you will only be able to get a torque wrench on 4/9 bolts if using 3/8 size torque bit.
(A long 6mm ball head allen driver would help here.)
This is due to how wide the blower case is and prevents straight on shot with the bit, causing you to have to use a Allen wrench on these “no space” bolts. I used 1 of the bolts that was torqued to spec to gauge how tight I got the other bolts with my Allen wrench. Now install your egr nuts on to the studs. Tighten both ends of your egr tube. Install your blower belt, making sure belt perfectly aligns with rest of pulley assembly. Once the belt is on verify all blower pulley bolts are snug.
Install your passenger side fuel rail/ injectors and tighten the two rail bolts. If you have a 07-12 car and using factory fuel rail-crossover, you will have to use the supplied hose and clamps to replace the stock crossover (it is too short). Plug all your lines, connectors back in on egr side of blower and injector harness. Now move to the drive-side of blower. Pending which throttle body you are running will dictate the steps you take next. If you’re running a smaller throttle body like myself, you want to install the adapter with supplied gasket for it. You will be able to put 2 short bolts on the far left of the adapter, then use the other 4 bolts to secure your throttle body with gasket to the adapter - longer bolts go on right side (through Tb, adapter and in to plenum).
Plug all your lines, connectors in (iat, throttle body, evap, and brake booster line). Next install whatever intake you are running making sure to connect your maf harness and the boost bypass line to it.
Look over your work, making sure everything is hooked up or plugged in.
From here you will want to insure your battery is charged or tender hooked up and begin loading tune or start making logs for your tuner.
Hope this helps, ENJOY!
