Hey guys, i am adding e-fans and underdrive pullies this weekend. How much of a gain should i get, and will i notice a difference in the throttle and get up n go of the truck?

 

Yea, you definitely will notice. I think the fans add about 2-3 to the wheels (from what I have read elsewhere) and the pulleys add about the same (also read that somewhere).

I'm sure someone else will chime in with a more definite number scheme for you.

 

you're pretty close there dirtyd88

 

I've always read posts saying the electric fans are a great mod.

 

dd88- Thanks, yeah the guys I'm ordering everything from said I would notice a difference right away. They said I'd be looking at 10-15hp gain total...

Yeah I've heard they are a great mod also, just didn't know if i wanted to pull the trigger and have it done. But now I am getting ancy cuz I haven't done anything to much truck in a while, so i figured why not....

 

The e-fans will give you noticeable MPG gains as well. I hope to have a set on my truck next summer....im undecided yet about UDP's

 

I am doing udp b/c i plan on super charger within a year or two.

Yeah the guy is supposed to order them today, i just have to tell him which kind to get....

 

GreenMachine do not put on the UD pulleys if you are going with a supercharger, I had mine on with grreat results and I was going turbo when I bought them but when I put the supercharger on I had to remove them...

peak gains will only be few Hp and TQ but the overall power curve will be improved with the E-fans

 

So its ok to use them with a turbo? It will be awhile before I do that so even if the udp won't work with it, i can use them until then, ya know....

 

yeah they will work with a turbo, and YES you can use them until you upgrade, which is exactly what I did then when you are done with the pulleys you can pass them on to another lucky individual

 

I also herd that it makes your truck pretty quiet too... not talking about the exaust haha, is this true? id imagine it is exspecialy on a cold start
