Default How is the install on EWP and UDP?

ive been thinking of doing these since my car is no longer a DD but how are the installs? im afraid of doing the UDP because i dont want voltage problems, but i dont have a system so im thinking ill be fine. and how does the ewp get wired up etc? also, for the udp, which should i get? thunder racing has a ASP 34% crank pulley for 80$ and looks decent from the pics, may order that as well as my ewp from here. tell me what you guys think.

The ud is really ez takes like 15 minutes. I have a huge system and i didnt get the alternator pully and i have no problems. The ewp isnt bad either the hardest part i thought was hammering out the impeller shaft. You can buy the wiring harness from summit or just make one yourself like i did its just a regular relay and fuse or circuit breaker

I would recommend buying a painless relay kit for the electric water pump. If you are interested I actually have one for sale. I'll PM you with a price and a link to the for sale thread.

I wouldn't do both. The alternator pulley would cause voltage problems with the added draw that an EWP would put on it. I didn't do the UDP because I relocated my battery to the back and even with good wiring it still has voltage trouble every now and then.

You can get the wiring from summit. I just did the crank pully and belt and left the alternator alone

the alternator it says is an overdrive, was guessing it makes up for the lost voltage from the crank udp? yeah im thinking i may just stick will the pulley and stay away from the ewp until later on if i make it a track car.
