Good Question! Maybe The guys from Weapon X can answer that question. I am somewhat concerned about blowing out the front and/or rear seals due to the increased crankcase pressure. I recently purchased a Mighty Mouse Z06 Mild Breather/Catch Can that I plan to install soon. I know that will help with the crankcase ventilation. (and the oil ingestion into the blower)

I do not track the car and I am not hitting WOT very much, but I have hammered it a bunch of times at WOT and have had no issues....I have not had any heat soak issues at all...My IAT temps (which is IAT2 on a normal Z06) have been great. At 80-90 degree ambient temps and normal driving they are 115-135...With more aggressive driving I have only had temps hit 150 once...I love the setup and the custom tune on the engine and the trans. The car is so much more alive! The power is nuts!

Making around 600whp on the LT1 shortblock is not going to compromise the longevity of the engine life. The tune on Matt's (managerman's) car is very conservative as well. For example, we have seen C7/Camaro6 owners making 800whp on those for years now without missing a beat. That say a lot itself.

The weak point on the LT1's are the pistons. Keeping them cool with the proper fuel trims and timing is what makes them last. As long as the tune is safe, and the engine is not facing detonation, or anything that would cause overly excessive cylinder heat, (Which this applies to the stock LT1 as well.) I do not see it jeopardizing the piston/engine life at all.

Yep, pretty much any PD type supercharger located in an intake valley is going to be subject to heat soak. It's just the nature of the beast. We do offer several products to combat that though.
