Estimated HP gain with a 2.2" pulley?
What is the estimated gain with a 2.2" pulley? I am curious, as I might make a appointment to get some runs on a dyno with a before and after. I found a local one that has good prices.

WOW
I really didn't expect it to that much. I know 20 hp really isn't a ton, but still much more then I expected, I was thinking around 5 - 10

when i put on my 2.55 form the 2.8 even though i was getting KR in 2nd and 3rd gear... 1st gear i was getting non.
When i had the 2.55 on first gear i could just lite up the tires and bounce of the rev limiter
did it by mistake because i did not think it was going to smoke the tires that much

And this will add more torque than it will HP...
But make sure you are tuned for it and have no KR.... KR is engine death

Yes, you need a 3.5" or you will get mad slip. Part numbers are in Techinfo.

Have you read the top article in this section:

Do you have a scantool and fuel pressure gauge?

Oh yeah, damn I am empty-minded today. I forgot to check techinfo for the #'*.
I got my scantool, 0* KR everytime I check. Fuel pressure gauge is being picked up tonight.

AZ bozo'* look at you like
, where the NAPA guys will say "Oh, you want an oversized.......this look right?" And they'll pull out a ruler to verify it for you.
