Are you guys full bridging on two piece seals?
Is it a small bridge so the corner piece doesn't fall in?
How y'all goin about that
I have a spare na s4 center iron I could port an toss in my half bridge
I know they suck, with the egr shiz an all, but it's all I got

Only relieve the secondaries and put the rear apex seals in backwards so the corner piece is against the primaries.
I'm also using Atkins seals which have a long corner piece, which isn't so hot if you want to really open the exhaust up, but I don't so it's okay.

Pretty much. You can technically run OEM multipiece seals with the corner piece against a non-relieved bridge port but most people don't recommend it, and I've never tried it. Really, when everything is good, the seal can't fall in, but when things get worn then they can get iffy if the seal somehow decides to rock over.
All aftermarket 2-piece seals that I'm aware of have extra-long corner pieces so you can safely run them against a bridge, but I don't quite have the gonads to run them against a relieved bridge.
Ran a compression test today after 13,000mi. (Haven never run one on this engine before) 100psi front/90psi rear on a gauge that is known to read low compared to others. It's about as good as I've ever had an engine. Heck, I've had an engine that started and ran just fine read 50psi on this gauge. I think MazDave has a factory compression tester, if he does then I'll see if I can scam him into using it on my engine to see how well it's doing.

Sweet I might hafta giver a go
I'm going to dyno my half bridge soon but I highly doubt I'm over 200 ish
So I'm either going to full bridge with S5 rotors
Or leave the 9.4s in and put on a to4b or e
Also putting on itbs regardless of boost or not
Either way I'm going to build my friends 12a this way.
I kinda regret not doing it to mine the first time
Robb at pineapple said it would have worked better with the S4 intake.
But I was afraid of the corner piece gettin effed
This way makes way more sense
