RE: New Nissan Turbo design

[Richardson, Thomas Morgwn - RICTM002]

I read somewhere that Nissan had already given this a try on VG20 turbos, and they are apparently quite cheap but difficult to use on anything because of the huge exhaust housing. -----Original Message----- From: Mark Alford [mailto:[EMAIL PROTECTED]] Sent: Thursday, 13 December 2001 9:19 AM To: Ozdat discussion list Subject: New Nissan Turbo design Exciting news for all Turbo guys out there.   I was talking to an engine builder last (He was modifying my crank) and we started talkinf FJ20 turbo's. He told me that Nissan has just released a new turbo design, intended for small trucks, which he believes will suit the FJ20 perfectly.   The turbo is a roller bearing turbo, which I know is not a new thing, but what they have done is used a large exhaust wheel housing and added a flap inside. This flap stays closed until a pre determined level, effectively giving you the effect of a smaller turbo (eg, it spools up quicker) once it reaches a certain level the flap is opened to allow the boost to keep rising. It was apparently published in the latest Automotive engineering magazine, and hasn't even reached the "hot up" shops yet.   The flap is electronically controlled, so creep shouldn't be an issue, and can be set to open at any level as programmed. Obviously You will need a programable output on you Engine management to control it.   Don't ask me any more about it, as I don't know much more, but keep your eyes open.   Mark.   --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/ --------------------------------------------------------------------- --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/ ---------------------------------------------------------------------
