I'm curious too...Originally posted by fatgroundhog
Snowvert has some good info as usual. However, he's still the only one I've every heard talk so badly about the divorced wastegate downpipes. I've never seen anything to support this view, but have seen data that shows the benefits. I do know that if given the choice, most prefer the bellmouth, but they cost more.
Snowvert- can you educate me on the statement "boost plays a small role in timing on the wrx"? You've said that a few times and I don't get it. I thought boost netted higher CR. Higher CR requires either timing adjustments or higher octane. Thanks.
Also, here is a decent link to reviews of parts. Some of you have probably already seen it.
