Can anyone give me a sense as to the pros and cons of the TRD supercharger? Also, how much, if any, value does a supercharger add to value of a used 80-series? I tried to do a search on this topic, but I couldn't find anything directly on point. I did see some stuff that indicated you must/should run a snorkel if you have a supercharger. Why is that? Also, why do some people prefer turbochargers (which appear to no longer be made) over superchargers? TIA!!
