Glenn Posted January 24, 2012 Share Posted January 24, 2012 (edited) The Directors need your help! Please contact your local Director if you have a 98-00 Mustang and you race it in CMC. You can also email me @ Glenn_Landrum at msn dot com or PM me here. This is very important for the series and your fellow CMC'er of the same platform. Hurry now before you too get put on 235's!

Glenn Posted January 24, 2012 Author Share Posted January 24, 2012 Guys - I may have my years wrong. We need to know about those cars running the returnless style fuel systems. Quote Link to comment Share on other sites More sharing options...
ShadowBolt Posted January 24, 2012 Share Posted January 24, 2012 Guys - I may have my years wrong. We need to know about those cars running the returnless style fuel systems. Mine is a 2002 4.6 and it has this system. The fuel pressure can't be set (as it is controlled by the PCM). There is no return line.

JoeK Posted January 24, 2012 Share Posted January 24, 2012 Ford went to a returnless style fuel system in 1999, with the body style change referred to as the "New Edge" or "SN99". Same chasis (SN95 or SN99) from 1994 thru 2004 5.0 pushrod engine (in those years) from 1994 thru 1995 4.6 modular engine (in those years) from 1996 thur 2004 return style fuel (in those years) from 1994 thru 1998 returnless style fuel (in those years) from 1999 thru 2004 So how does a different fuel regulation style affect tire size again?

The tire thing was a joke. My bad. I need data to prove or disprove that the SN-99 guys can or cannot make the power numbers needed to run in CMC. Since we only have 2 in TX and one is making the numbers and the other can't w/out all sorts of issues, I need help is figuring this out. If I have 10 of them doing one thing a 1 doing another, then I know where the problem is. We have a 3rd in TX for 2012 and I'll have that data point as going forward.

ShadowBolt Posted January 25, 2012 Share Posted January 25, 2012 The numbers that are the problem are the air/fuel ratio numbers. I don't think power is the issue..........if I understand correctly. JJ Quote Link to comment Share on other sites More sharing options...

Spencer Posted January 25, 2012 Share Posted January 25, 2012 I just made 240Hp/280tq in a 2000 GT with the following mods on a dynojet following the NASA dyno proceedure. Flowmaster catback offroad xpipe CAI This was with stock exhaust manifolds, I should be able to get closer to 260 rwhp with long tubes though. Does that help? I dont race CMC yet, but that is the goal for the car. Quote Link to comment Share on other sites More sharing options...

Alien Posted January 25, 2012 Share Posted January 25, 2012 Good thing he's not running an LT1 7.23.5 Ford 4.6 2V cars may use an external base timing adjuster such as Steeda #555-3410 as long as the adjuster serves no other purpose other than to adjust base timing and the timing can be verified visually.

What we are trying to do w/ the 99-02's will work for those few late 98's as well. Quote Link to comment Share on other sites More sharing options...
Adam Ginsberg Posted February 2, 2012 Share Posted February 2, 2012 Pretty sure that late 98 cars are returnless. According to a former Ford engineer that worked on the Mustang project, the returnless fuel system was implemented in the '99 and up MY Mustangs. Everything to the end of the '98 MY run had a return fuel system. Quote Link to comment Share on other sites More sharing options...

cozog1548534733 Posted February 3, 2012 Share Posted February 3, 2012 "Late 98" is the start of "99 MY". There's a diff between calendar year and model year. I'm just sayin.... Quote Link to comment Share on other sites More sharing options...

ShadowBolt Posted February 3, 2012 Share Posted February 3, 2012 Glenn, What have we (you) learned so far? How many cars have the returnless system and how many are having trouble? Jerry Quote Link to comment Share on other sites More sharing options...
