I had 20* @ 20psi. Ended up lifting my head and blew Cometic HG. I only have 10mm studs so I backed off to be safe.

Maybe a little late...

I used to run ~20* at 16psi with e85, but I was running a smaller turbo (50 trim). 16* at 20psi certainly seems like it is in the ballpark, but be careful. All setups are different.
RIP Nate(480sx)...

Damn guys, I've been running 16 degrees ramping to 19 past peak tq on 18 psi on a 60 trim .63 t04e on 93 pump in the florida heat forever. Got blowby and ripped my block apart and just have worn rings. Never blew a felpro with the old satrun arp studs and my pistons look great for being from 2006.

I think I need to re-visit this again. When I lifted the head, I was using this one tq wrench we had. When I redid the setup, I used a new craftsman tq wrench. Regardless of what, I want to take baby steps so I can enjoy her. I ran a 600cc by 3 cars last week from around 50mph to I am guessing 140mph (I know I was close to hitting redline in 4th with j30 diff).

Kedbmx made 800whp on 10mm studs. So I had to have had wrong tq on the first time around.
