MONGO510 Posted March 3, 2009 Share Posted March 3, 2009 I want to run a MSnS system on my Z project car. How well will the MSnS work with a fairly hot cam(282 advertised,242@.050)? I need to know if it will idle ok. I ran a Holley "Projection" system years ago, and was not real happy with it. It was the analog system. The MSnS looks like a great setup, but I have not seen any mention of Hot cams and Idle characteristics. John Quote Link to comment Share on other sites More sharing options...
zercs280zx Posted March 4, 2009 Share Posted March 4, 2009 I've always wondered the same thing. If someone knows, please chime in. I've heard that high duration 280 + causes too much overlap and can effect vacuum, which is important to maintain in an EFI system. I don't have any accessories, I just need vacuum to get a MAP reading for Megasquirt and a dizzy ref (Fuel-only), so I'm wondering how high you can go or what is recomended. Is this only a issue for stock EFI systems or can Megasquirt adjust to high duration and high lift cams? Any one running ~.500 lift, 280 + duration cam in an L28 NA with Megasquirt? Full build: Lonewolf intake, ported and shaved P79 with a 3-angle valve job. Thanks. Quote Link to comment Share on other sites More sharing options...
X64v Posted March 4, 2009 Share Posted March 4, 2009 MS will run pretty much anything. Even if in the most extreme case you can't get a steady vacuum signal, MS will do Alpha-N. Quote Link to comment Share on other sites More sharing options...
1 fast z Posted March 4, 2009 Share Posted March 4, 2009 I run a 292 adv duration, with .600" lift on a NA 3.1 liter with 12-1 compression on pump gas. Daily driver running on a map signal. Takes a bit longer to tune than a stock cam motor, but it is pleny doable. Quote Link to comment Share on other sites More sharing options...

SidWell Posted March 6, 2009 Share Posted March 6, 2009 I have a modified intake, cam, head and exhaust. At idle, the MAP is 79. I am still working on the tune but it seems to be working nicely so far. Quote Link to comment Share on other sites More sharing options...
