WEAPON-X4: "XXXcessive" Package (Stage 4 Power)

This package has the ability to get the power package you need with your choice of headers.  This frees up air flow through the porting and full exhaust or option 2 (advanced) with more porting, along with a higher flowing intake/filter and larger heat exchanger.  All of these packages are designed for future staged growth if desired.  This stage adds a more aggressive pulley ratio, addresses fueling larger injectors, and much needed cooling: less restrictive incoming air and exiting air, more revolutions per minute from the factory supercharger inhaling this air, upgraded heat exchanger to cool this air, a tuner in our network that will give you a qualified tune to make sure your newly introduced air is getting enough fuel, and a couple of protective modifications needed to keep the supercharger operating at it's best.  Some companies out there don't have or aren't experimenting with these cars, so they offer cheaper packages, but this is a Cadillac and it's not worth saving a couple hundred dollars to just get the added HP without the needed protection to match the performance.

*** For those with concerns of GM powertrain warranty, an extra PCM can be purchased on here which can be used for the tune while keeping the original one stock.

The weapon X4 package option 1 (from stock) includes:

1. New Era Intake - replaces the factory air box with an open style air filter that is one of the best intakes on the market.
2. LS7 ported throttle body - flows more freely than the small stock 87mm throttle body.
3. Stainless Works headers with x pipe (cats available at additional cost) connecting to factory mufflers eliminating the crimped section on the passenger side as well as both crimped pipes coming out of the inefficient factory x pipe.  (SW exhaust is easily added to this in the future if desired.)
4. Ported snout - lots of material can be removed from the snout inlet for more airflow and less restriction.
5. Supercharger Lid Spacer - adds more volume on the compressed side of the case and also allows ports for meth or NOS if you want to add now or later.
6. Metco 9.1" lower pulley and crank balancer - light weight crank pulley with replaceable rings for adjusting desired output.
7. Metco Interchangeable Hub with 2.5" upper pulley - combined with 9.5 lower nets a 3.82 blower to engine RPM vs. the stock 2.7 ratio.
8. 100mm and 50mm idler pulleys and bracket needed - gives the upper pulley the belt wrap and clearance needed for the extra power.
9. Heavy Duty belt - new length needed for different pulley diameters.
10. Solid isolator - replaces the factory isolator which wears a groove in the snout shaft and will eventually sound like a marble bouncing around inside of your $70,000 luxury sedan.  This is an easy swap while the snout is off for the new upper pulley installation.
11. SLP 160° thermostat
12. Track Attack HX - keep your blower cool with the most versatile heat exchanger on the market. 
13. NorCal heat exchanger tank/ice box - not only adds 1.5 gallons of extra capacity but you can also cycle ice through it at the track.  A must have!  
14. High flow pump with brackets and fittings - increased flow to supply larger heat exchanger
15. ID1050X fuel injectors - increased flow needed for the additional air being ingested and the come with the data to plug into the tune.
16. Catch Can - goes in-line with the stock PCV system to keep oil from being ingested in the blower from the motor.  GM has no filtering system so oil builds up and pools inside the supercharger which reduces the air flow and in extreme cases has even fouled plugs.  With the increased blower RPM and effective boost we highly recommend this simple filtering catch can system.  
17. Basic Instructions for installation of parts for your shop or you DIY guys.
18. Recommended tuner in our network to dial in your mods if you don't have a preferred one on your own.
