Gains from 3.5" pulley and supporting mods?

I had plans on doing up my GP with a 3.5" pulley and supporting mods this christmas (downpipe, intake, plugs, tstat, etc.)

Also grabbing a scangauge to monitor KR.

What kind of gains will I be looking at here?
 


Look to gain KR, skip the DP & get some SD Headers, then look for some nice gains. I have all the supporting mods + a little bit more & will be going custom tune & 3.4 in the spring.

Will grab the SD headers instead. I'm looking for actual numbers, though.
 


3.5 pulley is pointless it requires pretty much the same mods as a 3.4 pulley. I say since your doing headers and a tune try for the 3.4 pulley.

I'm buying a modular pulley setup, but I guess this means I can grab one with a 3.4" pulley instead.

Good news, and a little more power, I guess.

Thanks for the advice.
 
if you are getting a custom tune i suggest going with a 3.6 or 3.5 pulley and adding more timing. depends on your altitude and car though. on my car. i was seeing lot's of kr with the headers, supporting mods and 3.4 pulley. (i'm 2 feet below sea level)

Well, I'm buying a modular pulley setup. If I have tons of KR, I'll up the pulley size.
 


most ppl who run a 3.4 with just headers are running like 15*. if you go with the 3.5 or 3.6, you can add timing, but if you get the 3.4 and at 15* you still have KR, then what?
you will have to buy another pulley.
