Message	compression (8.5.1) or 8.1 for their builds as these compression numbers are more desirable for bigger power. I also think you'll find the exception being the higher compression ratios. Ash is also one of the more experienced and knowledgeable guys in the Z community. Not that you have to listen to everything he says but he's not steering you wrong here. Hes not saying you cant run 9.1 he's simply saying that 8.1 was more desirable in this case. There are in fact guys who have turbo'd the NA engines with stock NA compression 10.5.1. I know guys who run 9.1, I even had for awhile without issue, but it isn't ideal in many cases. It can be a limiting factor in reaching higher hp numbers with increased boost reliably. It depends on what you're building towards. " I told my son, you have to catch the football other wise this just looks like child abuse." - My brother

Most people with aftermarket pistons are ~9:1 - Antihero 16:48:54 02/11/13 I was actually just looking into this. - AHos(Chicago) 15:29:14 02/11/13 I can see where the confusion is - Zvil (FL) 09:47:10 02/12/13 I went 9.2:1 compression. - Woody75 (Denver) 10:16:55 02/12/13 Definitely agree! More compression is usually better.. - flashstar 14:06:32 02/12/13 yep - aliaZ 21:29:51 02/12/13 I actually just sent you an email about this. - AHos(Chicago) 23:13:13 02/12/13 yep. I'll respond later... (n/m) - aliaZ 06:48:50 02/13/13 No rush. Just checking. Thanks! (n/m) - AHos(Chicago) 09:35:35 02/13/13 Ok no one argues that. - white22sky 09:39:55 02/13/13 I maxed my turbos out (28psi) and I was still fine. - Woody75 (Denver) 09:54:39 02/13/13 28psi? was that on pump gas? (n/m) - Zvil (FL) 10:16:01 02/13/13 No (n/m) - Woody75 (Denver) 10:21:58 02/13/13 28PSI is in the area I was thinking. - white22sky 11:02:44 02/13/13 My reasoning would lead me to believe - Zvil (FL) 12:12:54 02/13/13 ALSO - Zvil (FL) 12:23:48 02/13/13 Yes. - white22sky 13:09:44 02/13/13 yep, and it's also the same reason in a roundabout way - Zvil (FL) 20:01:02 02/13/13 So lower compression makes a more efficient turbo, generally - white22sky 10:22:26 02/14/13 Re: Ok no one argues that. - Properstyle 06:40:39 02/18/13 With today's turbos and breather mods, these cars make boost - zellamay 10:41:13 02/12/13
