Ported M90 Supercharger
ZZPerformance has long been considered the leader in M90 blower performance. The port work done by ZZPerformance represents years of in car testing, chassis dyno'ing and running designs on our exclusive supercharger dyno. This is our Gen 3 M90 ported blower case which has been inspected, ultrasonic cleaned, CNC ported, and the needle bearings have been replaced. We have spent countless hours determining the optimal blower case outlet design using our Supercharger tester. We have tested all of the most common blower outlet designs and this is the best performing one.
We hold the record for the highest Gen 3 M90 dyno's on a FWD Grand Prix by a large margin making nearly 15% more power than any other car using a non-ZZP enhanced blower. Our supercharger dyno gives us the ability to build and test designs in house. Buying a ported blower from another company gives you guess work on outlet design and efficiency. Only ZZP gives you researched and proven performance! Tests show that CFM gains begin at 10,000 rpm blower speed. We recommend porting your lower intake or running our lower intake to maximize performance gains.
How to order your supercharger case:
1997 fits the '97 Grand Prix GTP, '97 Regal GS, '96-97 Bonneville SSEi/Park Ave Ultra
1998+ fits the '98-03 supercharged Grand Prix GTP, 98+ Regal GS, 98+ Bonneville SSEi/Park Ave Ultra, or '04-05 Monte Carlo/Impala SS
(L36 Supercharger kit doesn't require a year to be selected.)
Inlet Porting: We offer inlet/outlet porting for the Gen 3 supercharger, However inlet porting is only recommended for people that have the 75mm Northstar throttle body setup or our old 77mm billet throttle body which has been discontinued.
Outlet Porting: All of our blowers come with our ZZP exclusive blower outlet porting that was developed using our supercharger tester which measured overall outlet temps and airflow.
If you are piecing together a ZZP L36 supercharger kit that will not require you to swap your cylinder heads, you will need the following items:
- "Gen3" "L36 Conversion Kit" Machined Intake Manifold
- "Ported for L36 Conversion Kit" Supercharger
- "L36 Supercharger Kit" Modified Fuel Rails
This does not make a complete kit, these are only for the people that need 1 or more of the main custom items.
