Message	is about 185 psi with 10.5:1 Compression Ratio (CR), so a TT with 8.5 CR would be about 150 psi. Pressure difference is max at 5psi on 1-3-5 bank and 1 psi on 2-4-6 bank, well within spec. ZUL8TR in Orlando,FL

(n/m) - J-Mart 14:30:34 09/22/16 Numbers look good - ZXRider 15:33:43 09/22/16 so couldnt boost over 14psi - nissan300zxwork 23:50:29 09/22/16 Those numbers look OK for a TT. The NA compression >> - ZUL8TR 04:44:58 09/23/16 Interesting that built 8.5:1 engines < stock comp #'s - ZXoltan 10:20:47 09/23/16 Forged pistons require more clearance. That would likely - MixManMash 08:15:35 09/24/16 The piston rings contain the pressure, not the piston - ZXoltan 08:48:17 09/24/16 cranking compression typically suffers a bit with big cams - LitlElvis 14:54:40 09/23/16 This. (n/m) - MixManMash 19:08:33 09/23/16 Agreed, Brett, but what about forged motors w stock cams?
