With an intake, or exhaust, dont install em right you get to redo it. Thats where the risk comes in.

Pulley's themselves arent really rocket science fella's.

I wouldnt even compare these to FI. The risk is much much less. With Pulley's your not changing really anythinga bout the engine except for how much inertia is lost/used to turn it.

With intakes, exhausts, tunes, etc etc your changing the dynamics of how the car works internally. FI takes that to a different level altogether. If anything pulley's should be one of the lowest risk items. Unfortunately it attaches to a place where a wrong install could be bad.

You can compare a pulley system to a lightweight fly wheel. Good stuff unless again installed wrong.
Well... ok... yeah... but it's the undampened vibrations that ultimately cause fusion and extra wear and tear on the crank.

I think the real debate is whether or not a V6 is "naturally balanced" enough to not be overly concerned, and I think it's unknown at best, especially considering our motors rev pretty high, and high revs will greatly exacerbate the effects of undampenend harmonics.

Just sayin'...

On the other hand, aren't our cranks forged? I suppose it could be sturdy enough to withstand the extra vibrations, but again, it's not clear.

As to the FI compariosn, I just meant that I'd rather risk the motor's longevity for a 100+ whp increase in power than a 5-6 whp increase...
