RocketSled said:I beg to differ. The answer is: Absolutely.
I've blown the serpetine belt off my Vortech twice now (it tends to happen when I lift throttle on a high-RPM pull). Both times, the first thing I noticed was that the power steering went away (followed in short order by the "service engine soon" message and rapidly increasing water temperatures).
However, in both cases, the engine ran fine without the blower turning (of course, partial throttle only). Each time, I had to drive it another 20-30 seconds to get it off the road to somplace "safe" and there was no perceptible difference in throttle response.
Since it clearly runs fine without the blower turning, it's safe to assume it'll run just as fine without the blower at all.
A blower-tuned PCM without a blower won't do any harm, but the opposite is not true. I would not recommend driving with an un-tuned PCM after a blower install.
