UNDERDRIVE PULLEYS
 

I am planning on gettting a CAI and Tune and was wondering if it is worth it to get the underdrive pulleys (steeda)?

sure

RE: UNDERDRIVE PULLEYS
 

Yes, if you plane on racing it. If not, you probably wont see that much of a difference.

Good bang for the buck....you'll get up into the powerband quicker with them https://mustangforums.com/micons/m6.gif

they are good for an gain of about 10 HP and a bit better MPG increase. less drag on the engine.
Do not install UDP if you plan on a Huge Audio System with Amps and stuff. also if you have the shaker 1000 system it might not be a good idea, other than that sure go for it, I love mine

2k05gt----Whats the deal with the udp and a system????

RE: UNDERDRIVE PULLEYS
 

The UDP slow down your alternator, A/C and power steeringby 25%, this drop of avalable charging would not affect a normal car under normal conditions like traffic jams or sitting idle listening to the radio. but you add a load like mutipleamps, this will excead the avalable charging capacity and you will kill the battery allot.

Get a bigger alternator and the udp
