Bull. It can in theory wearout your front main seal faster or front bearing. but again that's in theory there is no way to really measure it. And they don't take that much horse power to run if you set them up properly. 20-40 maybe, and if a recirculatory valve is used then they use no HP when off boost. You can also set them up with a clutch pulley that kicks on when a full throttle switch kicks on.

 

In my application, the supercharger and motor have been extremely robust. I have 287,000 miles on that motor. 180,000 with the supercharger. The worst thing I find with the supercharger is the belts. the procharger is setup to tie into the serpentine belt so when it breaks, you lose alternator water pump etc. And the belts DO break. Like 25,000 miles is a long life for a belt. The idler pullies and tensioners take a beating too. Then when the pullies get sloppy, the belt chafes and lasts really short.
The turbos setups are way more fun to me. Lots more variables to mess with and power gains are unbelievable.

Lol I knew people were going to catch that RWD business from procharger. I think their form was setup with RWD as default. No way is buying a supercharger setup and building a motor going to touch the bang for the buck of a HMT setup. I just threw it up here for illustration that superchargers can be made to work pretty decent.

The strain a superchrager puts on the engine to run it is very small in comparison to the strain brought about by the increase in horsepower. This is not to say that it will not strain the place you mount it to. For example if you half *** install it to the mounts that are supposed to hold the airconditioning compressor its likely to flex and possibly break the mount.

As stated by others here it will strain the pullies and belts. Its best to have the supercharger on its own pully and belt to avoid wear on other devices driven by the belt.

 

as i said that is what i have heard i didn't know for sure so i asked.

 

prochargers flow a lot of cfm, so with the honda's i wouldn't see why but with a t3/t4 it will hit much sooner than the procharger because the spool goes by engine load and superchargers go by rpm.

So ya on a high revving motor you can have a big turbo and it would rape sause a supercharger setup because of the spool up time.

So what it comes down to is when will your powerband start? and how much cfm you're flowing.

Remember PSI != power.

Yes psi is a factor but it all comes down to CFM
