IMRC Actuator Mod

Can it be done as described, would it make a difference, how would you do it??

Click here: http://www.cardomain.com/member_page...page_id=404227
and read the paragraph under update

or below

I performed the IMRC Actuator Mod. I'll explain... The SOHC Focus' Have 8 valves. Due to lack of power, auxillary(or secondary) valves kick in at 3500 rpms. It's alot like Honda's VTEC. What I did was I removed the imrc actuator that makes the aux valves kick in, I manually put the lever in the open position, so now the secondary valves are always on!! My acceleration went through the roof!! A guy tested the mod at the track, and it shaved a second off his 1/4 mile!!! I'm really glad I spent the time to do this. If there are any other focus owners with the sohc spi, drop me a line and i'll tell you how to do it.

Works fine. Sometimes I take it out, but then I remember why I did it. My car seems like a pig when the SWAB is taken off. I dunno, I just like it better with the SWAB.

That is fundamentally impossible.

Keeping the secondaries open will affect low end acceleration ALOT...but then the car does not have that kick you get at 50-55mph. The car makes no more power then it did before.

Funny, mine IS faster at the track with the SWAB. I won't argue with you, I don't need to. Try it. If you don't like it, so be it and return it to the way it was. Either way you're not out anything as it's a free mod. There are quite a few happy people who have this mod and are quite content to keep it.

Oh I am not arguing with you about it being faster.

No way can you pick up a full second at the track. Running at the track all variables come into play such as off the line power.
