[QUOTE="EvilTwins, post: 10867319, member: 62345"] I'm fairly certain this is a flawed concept, using a wastegate to vent excess boost would not be a good idea at all. What you need to remember is that unlike with a turbocharged setup you aren't simply venting engine exhaust (which needs to be vented anyway), but rather you would be venting boost. That boost you would be venting requires HP to create - taken directly off the crankshaft. While it might work well at low-mid range RPM's as soon as you start venting actual boost the total efficiency of the setup would go down the toilet. It is my thought that this is why you don't see people doing something like this. I think the only way you could accomplish something like this would be to invent some kind of clutch assembly that would start slipping in the higher rpm ranges where you are making excess boost, this would be the supercharged equivalent of a turbocharged setups wastegate. This would not be easy to accomplish at all (hence why it does not exist). If you could install some sort of CVT (transmission) between the engine and the supercharger that would also work. Frankly though it becomes easier/cheaper to go turbo or twincharged. [/QUOTE]
