Don't recommend them. Can cause oil pump damage if the damper pulley is not balanced right. Also possibility of over heating, stiff PS, and undercharging. Not worth it for a few HP. IMHO

I have BBK UDP's put in, in 2010, I got 8 HP to the wheels never an issue so far, had this done when I got the HR Cams. Car now has 127,000km no issues still, finally parking it during winter. Replaced the stock battery after 6 yrs. Just my 2 cents

The Steeda underdrive is SFI approved and the damper pulley is a replacement of the OE. Some other types that piggy back on the original pulley are not as good.

Steeda crank and WP pulleys on my 08. Not a dramatic feeling by the seat of the pants dyno, but they do seem to give you a little more top-end, where the parasitic losses were previously at their worst. No dyno testing to prove anything, just musings.
