ok, so tomorrow I am looking at the 5.0 I may be getting for my car, so already I am thinking of possible mods, because I am crazy like that...

now I was looking into underdrive pullies, but I am concerned about overheating due to the waterpumpmoving slower etc. if I were to put an electric waterpump on inplace of the stock belt driven one, will I still get the added power of underdrives and have no problems with overheating?

you shouldnt have any problems of overheating with udp's. I have run them for quite some time in near 100 degree days without any problem. Get the pullies, 130A alt, an a electric fan out of a mark VIII or taurus(4000+cfm), fan controller, and a 180 thermostat. I am running this set-up and works great in the very hot and humid summer months..

you wont have heating problems....youll have charging issues because the UD will slow the alt down. for the couple of hp they are worth, i wouldnt bother with them

cool, I'll have to look into those parts. I know a fan wont be hard to find, so many wrecked taurus sedans and wagons in the boneyards near me.

now would it be better to run the wire to have the fan run constantly or hook it up to a switch and just switch it on every time I start up the car?

dccontrol.com and nothing else

An adjustable fan controller will control your fan on and offbya temperature probe. I have personally seen 8-10 HP gain with udp's on a dyno, so imo they are worth the money( i paid $25 for FRPP UDP's). I am running only the UDcrank pulley and the WP pulley so i am not dealing with charging issues.

an eletric water pump will add more horse than u/d pullies, so get that

I do want one, just got to get the motor first[8D][&:]
