#60626, "underdrive crank pulley"


          

i have seen a lot of talk on here about underdrive pulleys, are they worth the money?? yet i've heard that they can cause major problems if the motor isn't balanced. Will it cause problems??? if not what is the best one to get?? AFX or UR?? where can i get AFX??

I would definitley do a search for this, there is alot of good info out there.

Basically, UDP's will not hurt your motor. Other cars have had problems, but you need not worry on a 2gnt. Most people will tell you that it is the best bang for the buck! I just put mine on in the spring and I really like it. There are many on here who have had them for a couple of years without any problems.

The AFX fits REALLY tight. the TOP FUEL one that you get from ebay is a lot easier to get on for better or worse.

The AF-X pulley *SLIDES* on if you put it in the oven @ 450* for 2-3 hours. Just make sure to wear hot gloves and get it to the crank quick. Definately get the AF-X brand UDP.

2-3 hours? i had mine in the oven until it heated to 500* then took it out !!!!!!!!! i just took it and ran outside as fast as possible, slammed it onto the end of the crank, made sure it was on straight and took a rubber hammer and beat on it until it didn't move. I don't recommend this as dino once said it wouldn't be good on your crank and other things taking direct pounding. but i got it on a half inch or so, then took a torch, toasted that thing till i was bored, making sure not to fry my timing belt and then beat it a little more. then i put the crank bolt in, and if it doesn't thread in a few turns, then you need to beat more. cuz if you just try to thread it like that you'll strip out threads. i did this and the first outside threads came right off emoji!!! so make sure you get a few threads to pull with. crank that mother fugger on using all your strength unless you got a impact wrench. i was seriously spent afterwards! a cheater bar would help. just turn that thing until it is so tight it spins the crank even when someone is pushing ont he brakes. just make sure it lines up with your ps and ac. and your good. tighten those belts down really good. mine squeaked once when the wheels were completely turned. never heard them again emoji first try. woohoo! i love it. I can go up the hill to my school 500 rpms faster easily. probably more. never really tried, but it does have a nice kick to it! just odn't expect turbo style gains.

Having Problems? Heres my Three step solution to anything 2gnt related.
Step 1: Put down everything in your hands.
Step 2: Grab a lucky strike, Smoke it.
Step 3: Walk to the fridge, double fist some keystone ice, sit down in the shade, drink one beer, finish cigarette, drink other beer, roll a joint, smoke it, walk back to your problem, and in about 5 minutes the solution will come to you.
If not. Go here: here

If still nothing, your trying to hard. Start over at step 1.
