Generation III External Engine - Pulley power?

How much RWHP gain do you really get from a pulley?

Do a search. There has been numerous threads on this in the past couple of weeks.

Search did not work. I am on dial up :bang: Any help would be great. A yes or a no even.

I'd say about 5 - 10 is the norm.

Does anyone have links to dyno graphs showing true gains?

The guy who tuned mine told me 5-7rwhp

A couple of threads for ya. Read the second post in the first link. Every car will respond different to one. Could gain more, could gain less.
