Has nyone on here ever rigged anything up to the IMRC solenoid so they can activiate it whenever they please (as opposed to just 3000 RPM). I think since our cars get a huge boost around 3000-3500 RPM that it'd probably help out a little if we could drop it down a few 100 RPMs or just make it higher if we wanna drive economically. It'd be cool to just slap or hell even hook it up to one of the buttons on the steering wheel then push it to open them up and it'll feel like your in a movie!! Just another possible neat little toy on our cars.

The opening of the IMRCs is optimized at 3000 rpms. Any changing of that on a stock car will only decrease performance. See my attachment for a rough illustration.
Now any engine mods would probably change that - intakes, exhaust, heads, etc.

Notice the trend before 3000 rpms. The torque is beginning to taper off. The IMRCs open just past 3000 rpms and the torque trend goes up and peaks about 4500 rpm before reversing trends. Looks like mine open approximately 3250 rpms or there is a slight delay between opening and the resultant wheel torque.

if you had a supercharger or a low RPM torque addition, you'd want to open them earlier in the RPM band then correct? Vise Versa if you had soething that improved top end...?
[/div]
Maybe.
There are some instances in which you could remove them altogether...if you've got a turbo or a 3000+ stall converter.
In other cases, such as a centrifugal supercharger, you still need the IMRCs because the bottom end isn't helped much with that kind of blower. Though the optimal rpms to open the IMRCs would probably be different than 3000 in that case.
