Message	I have found that people think both ways with spool up time. I personally think in the same direction as ash on this one. Higher compression -> cramming less air into the chamber -> less combusted gas coming out of the exhaust -> longer spool time. I dont know if this is the right way to look at it... but the mechanical energy stuff make sense too. I found THIS post, showing that two very reliable sources think in the opposite direction. I want to go with higher compression and something along the lines of JWT 530's. You cant push that much boost anyways, might as well go with small responsive turbos. I am in no way an engine cycle expert, this was just my thinking. Still have a lot of research to do.

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
