Question Underdrive pulley ?

Is it worth doing it?

If you are doing a cam swap, definitely since you have the stock pulley off. If not it is still a good mod for the money.

maybe if your looking for that last .1% of power, but your air and alternator won't appreciate it.

it's worth it if you're trying to get every last drop of horse power out of her.

I researched the hell out of them.... not really worth it in my opinion. The 5% chance you need a jump cuz ur system is underpowered is not worth the unnoticeable 8rwhp..... just my opinion. If you want dyno bragging rights, then definitely.... good luck in your mods

Proportionally a good mod.

We sell 3-5 a week so I'd like to think that they're popular.

We have seen 10-12 hp with them when doing installs. I think they are a worthwhile mod and have not seen much of a drop in voltage. We normally install them when doing a camshaft, but there are many guys that change them before deciding to go into the motor.
