RE: inlet manifold

[Terry Rudd]

Kris,   I don't have accurate data on the Ford 2L Weber handy, but from memory they aren't that big  (something like 125-130 and 115 which is way too small for a 2L Datto engine). On a L18SSS (9.5:1) engine which has a very similar demand for fuel as a L20B I used to start at around a 140 primary jet and a 160 secondary but most of the other bits rarely needed changing except if someone had stuffed around with them previously. I recall that the average import L18SSS will cruise OK on a 130 main jet but it was a real pig when cold (that's Canberra cold like subzero), also you have to run a big secondary jet on a L engine to satisfy the demand for fuel in the high rev range. This makes them a bit thirsty if you hammer them but nothing like the lack of economy if you did the same with a 45 or 2. I was only concerned with cruising economy (i.e. mainly on primary jet) when I set-up a 32/36 - the secondary was for there to provide strong acceleration and that takes a fair bit of fuel on the old L engine no matter what carbie(s) are used.   A lot of this is also is subject to gearing and I use 3.7 or 3.9 with 5 speeds on the 1600's I've owned and my preferred settings would be good up to a 4.1 diff but anything shorter than that would need a rethink. If you set up a 32/36 so it wont hold a moderate hill on the highway at legalish cruising speeds (100-120) in 5th gear on the primary then it will annoy the hell out of you as you have to open the secondary and drink lots of fuel or change down with much the same result.   regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kristian Walsham Sent: Wednesday, 31 July 2002 12:17 PM To: [EMAIL PROTECTED] Subject: Re: inlet manifold Just a quick one Terry, is the standard jetting on the 32/36DGAV on the rich side for the L18SSS considering it came from a two litre Cortina?   Kris. ----- Original Message ----- From: Terry Rudd To: [EMAIL PROTECTED] Sent: Tuesday, July 30, 2002 9:53 PM Subject: RE: inlet manifold Kris,   S1 Bluebird has about the largest runners and base holes of any of the L4 downdraft manis and a S2 Bluey could be the same but I don't know anything much about the technical specs of them. There isn't much to be gained simply by fitting a larger runner manifold unless the head ports are at least the same size, some A87 heads have 38mm ports. There are a few holes to weld up if you use a L20B mani as they have EGR etc - not hard to do though.   Usually a 32/36 will run well with 12-14 degrees of initial advance on the Bluey S2 dizzy with vac advance connected and 96-98 octane so if it's not detonating then it's pretty close to where the engine likes. Usually going up hill at around 4000 rpm at WOT in 3rd on a 40 degree day will sort it out.   regards Terry        -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kristian Walsham Sent: Tuesday, 30 July 2002 9:58 AM To: [EMAIL PROTECTED] Subject: inlet manifold Hi all,        I have a 32/36DGAV on a L16 manifold on my L18SSS engine and seems too restrictive. I believe there is manifold from an L20B engine that is better suited. The head is an A87 but i don`t know if it is the larger or smaller port head.   Can someone tell me which car this manifold would be from please.     Also, i have the elec. dizzy and was wondering if i set the timing at 14 deg BTDC will this provide too much total advance with the vac advance hooked up? The car doesn`t ping though.  I have two timing marks on the front pulley, one lines up with 0TDC and the other lines up with 15Deg BTDC is this the correct way to set up the timing? I have never seen this before on a factory engine.           I use Caltex Vortex Premium 96 octane.  Sorry for rambling on. Much appriecated,                      Kris. --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/ --------------------------------------------------------------------- --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/ ---------------------------------------------------------------------
