Do I need a new supercharger?
All of the superchargers on the market claim to have a lower temp output. I am putting out some pretty high temps with my setup (19% super + 4% crank).
I hopefully won't fry the supercharger for quite some while. However I would like one that can take the added abuse.
I have seen the cosworth one but I'm not sure if thats what I want. I thought that you wanted to remove the two smaller openings on the supercharger out let. I was told they were used to lower sound output. I believe the Endyn supercharger had them removed.

You’re entering an area where few have been; it is you who will tell us from experience. It’s not known at this time if the 19+4 combination constitutes abuse. Pull yours in 30,000 miles and let us know the condition. Remove the intercooler at each oil change and look for warning signs like flakes of material or metal dust. Buy a spare SC and keep it for peace of mind.
I’ve seen pictures of an over revved and abused Eaton. The lobe coating had flaked badly and there was scoring in the case. When the lobes spin too fast there is some centrifugal growth resulting in case contact. In addition to contact, it takes more power robbing energy to spin; all of this creates friction-induced heat.
Endyn coats the case interior with an anti-friction material to help lower temps. This coating also reduces tolerances, which enhances efficiency (less wasted energy); which also results in lower temps/higher boost for a given rpm (the lobes can spin slower to produce boost that formerly took more rpm to produce). Not huge power soaked increases, but marginally measurable, nonetheless. Will this counter the 19+4 heat? You could try and let us know. I know this isn’t the definitive answer you were looking for, but I think anything said is only speculation at this early stage.
Closing the pressure relief ports does increase the noise level. My 19% Endyn combo with Gatorback belt makes a hellish whine. The tolerances on my SC were very snug to begin with.
At some point the laws of physics can’t be denied and something will wear out. Who knows how long that will take to happen?
