i have an apexi safc on my sc400, im thinking of putting in the safcII, does any one know if it will work with the sc4, has anyone tried it.

 

I have one on my 92 sc400. but because I could only add 5% fuel ( my previous racing car could handle up to 15% fuel increase), i really don't get much increase out of it... but it is useful and l@@K coool. just have it install and bring to a dyno place to have them tune it, you will get at least 10hp gain...let me know you setting on it and we can discuss it further,,

 

Why could you only add 10% fuel? I thought they were more flexible than that?
When version 2 is released in the US in April, I am going to get one.

 

if you add more than 5%, you will blow the head gasket...according to AFC from japan.

 

that's boguess,... you can add whatever percentage necessary to balance your A/F ratio, to which you could only know by dyno tuning with an O2 wideband sensor,... 14:1 is the std A/F ratio without forced induction,... so use that as a guide,... not percentages...

I've had one, and if you look at the post,.. you will see the amount of exact adjustment vs gain vs A/F ratio.

do a search in here for SAFC and I have the sheet attached.
