9:1 would be perfect for your setup then. You won't lose to much compression and keep your low rpms driving sufficient. but you will have the added benefit of increasing the boost threshold on your pistons...

If I have takers I'll set up a new thread with the group buy

Why would you buy 9:1 when you can get 8:5.1?

Why? Hmm maybe because I dont want to loose power and have to crank more boost to make it up.

Be nice to keep some factory power then have the boost at 12.. more power then u would have with the same car with 8:5:1

You guys got to remember lowering the compression down means less hp

yea lower compression needs to be compensated with boost, your off boost drivability will be affected.

look at my post above, you can get stock size valves that can take a beating or oversized for better breathing and durability.
