I should have asked the seller why the IMRC cover was off when I bought my car (plus a dozen other questions...C.org member). Anyway, I finally took my C-SVT up to triple digits - on a privately owned road, of course; mods...
In fifth, it took forever to hit 100mph; in fourth, it got to 110mph...I expected 125.
The IMRC is not pulling the secondaries open. I feel nothing around 3250 rpm, but maybe something at around 4k. I revved the engine in the driveway and the cable was pulling. The intake sound got deep a couple of times, but not everytime. The cable was pulling each time I got to higher rpm.
What are the common problems? Cable binding? My 1995 Escort GT pulls harder than this car over 4k rpm!!
