Exhaust sizes (HELP)

[Daniel Kroehn]

List,   heres a question for all you switched on turbo boys.  Following traditional lines for an exhaust, I was going to get a 3 inch system for my turbo project.  However after reading "maximum boost" by corky bell, it seems that he reckons that for the approximate engine power output of my engine, I should use a 2.5 inch system.  The book also states that for a turbo setup the least exhaust is the best?  I'm very confused by now.  Anyway back to the 2.5 inch set-up, this size comes from a few calculations to do with exhaust gas  velocities.  He recommends that the exhaust gases shouldn't exceed ~450 feet per second, and thus a 3 inch system would be capable of much more than that, so no good? There's a bit more in the book but at this stage I've just become totally confused.   Eagerly awaiting some opinions..................   Daniel Kroehn   --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
