Message	Yes, the volume above the piston at TDC divided by the volume above the piston at BDC will give you the compression ratio, but once you find that value, which is 10.5 on the NA, and multiply it by 14.7, which is atmospheric pressure, it should give you a pressure of 154.35. But he is getting a higher number, 186. Something must account for that higher pressure.
Follow Ups	Why is NA compression 186psi @ 10.5:1? Should be 154.35?>>> - AshsZ (Jobless In Florida) 18:27:48 08/06/01 Don't think so...I was told compression for a TT should be>> - Seb300ZX 19:00:37 08/06/01 I am asking how you can get 186psi with 10.5:1 comp. ratio>> - AshsZ (Jobless In Florida) 19:08:17 08/06/01 You're off bro. Gimme the stock VG deck height and I'll tell - SeedyRom 19:27:22 08/06/01 I dont know those values. What I am asking is how does >> - AshsZ (Jobless In Florida) 20:04:48 08/06/01 You're thinking too hard. - SeedyRom 20:19:55 08/06/01 With that in mind >>> - racer Z 20:41:13 08/06/01 I'd never thought I'd see the day when.. - got rice? 21:15:35 08/06/01 lol!

Nononono. Manual states 186psi for NA. >> - AshsZ (Jobless In Florida) 22:41:40 08/06/01 Friends NA was up to 215 in a comp test...is that ok? (n/m) - Russ ZTT (Jax, Fl) 07:15:10 08/07/01 Do you think temperature could cause that? - Marshall 22:02:59 08/06/01 That is a very good point. 31psi in heat. Hmmmmmm..??? (n/m) - AshsZ (Jobless In Florida) 22:43:08 08/06/01 I have a couple more thoughts about this... - Marshall 06:25:04 08/07/01
