Not ever a bother to educate.


First, Procharger does nothing to provide proper crankcase evacuation and only vents into the intake portion of the system.


Second, your engine is Gasoline Direct Injection and has zero fuel touching the intake valves to keep them cool and clean like the previous port injection LS engines had. Here is a picture of a LS engine with no catchcan and 142,000 miles:





and a LT1 with 19k miles on it:






And the dyno graph showing before and after cleaning the valves manually to show the loss of power that was regained: (dyno done on same day, same conditions and SAE corrected. Car owner did the manual valve cleaning and participated with dyno pulls and is an Aerospace Engineer)






So, look at a valve from your engine when new:






Note how the angles are precise and have tons of R&D into the shape, how the stem is undercut and how the tulip has a satin swirl finish. All to enhance flow and efficiency. So when you allow them to become covered in deposits, and the shape changes incoming flow and velocity of that flow is hampered and disrupted. Hence the power loss. Whats even more critical is now the valves in the ports closest to the point of ingestion are now becoming coked with larger more severe deposits than those furthest from it, so as the ECU commands the same amount of fuel for all four cylinders on that bank, the ones with most obstruction are now running richer than is optimum, and the ones furthest are running leaner than optimum so only the 1-2 in the middle of that bank now have proper A/F ratio.


Then lets look at what ALL GDI engines experience. Since the fuel is introduced directly into the cylinder, and only milliseconds before TDC and spark ignition, the injectors operate at 2,000-3,000 PSI so many times the raw fuel is forced past the piston rings washing oil from the pistons and cylinder walls and diluting your engine oil and reducing it's ability to properly protect, especially with forced induction stresses added.


Now we go further. With the way your Procharger comes, there is no provision for Positive Crankcase Evacuation. So as your engine was stock, at least there was the intake manifold vacuum present to positively evacuate (suck out) the vapors full of the raw fuel. water vapor, acids, and abrasive particulate matter all present in blow-by before it has a chance to settle and mix with your engine oil so wear is accelerated VS how your engine was stock. A system like ours provides full time evacuation to even better remove these vapors before they have a chance to settle and mix.


And finally, today's engines all come with low tension piston rings. This is to reduce parasitic loss from friction a high tension ring causes so the automaker can meet the CAFE fuel economy standards (same with the super thin oil they recommend that does not protect nearly as well as a 15w50 does) so any pressure present in the crankcase will cause a condition known as "ring flutter" where the piston ring vibrates at a high rate reducing it's ability to seal and this more blow-by enters and power is lost. This requires suction below in the crankcase, and pressure above. Our system, unlike how Procharger does it or other catchcans being pushed, provides full time suction on the crankcase never allowing pressure to build in the first place.


So, read this through several times. We know it is long, but there is no way to properly explain all the reasons and just telling you "because we said so", or "because so and so does it so you should" is not proper. We instead choose to educate and explain in detail.


Ask any questions you may not be clear on and we are happy to take the time and help. But bottom line is you spent a ton of money on the car, and now a ton on the supercharger, so to not properly address the issues you face and protect that investment properly (and no, a "Vented" can is NOT providing much protection at all and will result in shortened engine life as well) the price is very inexpensive when you look at what it does. In fact no supercharger company aside form Overkill addresses any of these issues properly.


Protect your investment, and become educated on all you need to know before adding anything to your build.


Cheers!
