Underdrive pulleys?

[GIG4FUN]

Never had UDP's but 300$ for 5 HP is not worth the trouble

Well, it really depends on how a person thinks.

I wouln't consider that a universal truth

Which is why you wait on someone to buy them. Then they get a supercharger. Then they sell them to you for 3x less.

No arguments here

bumppp

i know this is old, but i'd really like to get some underdrive pulleys for my 5.0. on my 2010, i gained 9-10hp and 8tq at the wheels just by adding underdrive pulleys and i'd think the gains on the 5.0 would be slightly more. steeda, bbr, anyone make any?

With the speculation of #8 running hotter therefore being the weakest link I'm not sure if I want the water pump pulley to turn slower.

Seeing this thread again gives me a headache. Smog pump? Seriously? This isn't an '89 LX.

The AC compressor does not put any drag on the engine when it isn't engaged. It's called a clutch. You may have heard of it.

I actually haven't heard of any UDPs out, but I'm sure there are some. They will not get you as much power on the Coyote as they did on the 4.6, mostly due to the lack of the PS pump, as mentioned before.
