What is the word on the underdrive pulley on an automatic max? Will it make a significant difference or is it a waste of money cause i have an automatic?


thanks in advance

 

i got it and the first thing i noticed is better take off's

 

so i am assuming you have an automatic as well.?! Well every bit helps, i have a Y-pipe which helps at high rpms (5k-up) so the pulley would help me off the start...........cool!

 

yeah you will notice a quicker take off and i do have an Auto

 

What added strain does the pulley put on your engine?? I'm gonna have my max for a long time so i'm looking towards realiablity. Any ideas?

it really depends on how U drive, if u drive aggressive constantly of course the tranny wont last as long, try looking into a VB recalibration, which is what i will be doing in March and maybe a tranny cooler, i got mine from permacool if your interested i can get you one for $65 shipping and handling

 

yeah, its my ONLY vehicle so i depend on it alot. Most of my driving is done is highway driving.

 

are u under warranty??? and if u are have u gotten the TSB done on your tranny??? concerning the soleniods and TCM

 

have another 3000 miles left on my warranty. I've seen alot of "TSB" but i'm not sure what that is.

 

it stands for 'Technical Service Bulletin' here is the one on our tranny

Wow, never knew about that. What happens after i pay the fee for the TSB what happens then??

Sprint had a UDP on his car?!?



Did he know about it!

 

 

So the UDP only helps on quicker startoff? Any overall gains?

 

I got one also, you do notice the difference, a little better low end power. Not a waste of money

Well, I got ypipe, cat, cat-back exhaust, hybrid intake, and vb.


How much does a UDP cost anyway? It includes the belts right? If it's not too expensive, I might just give it a try.

I don't see how having other mods could possibly effect the performance gains from a UDP. It has no effect on how the engine breaths or anything like that. All it is doing is decreasing the rotational force of the crank pulley and there for freeing up more HP to the wheels. It should work equaly well on all maximas(with the same tranny).

 

Hi guys, after reading this thread and hogan's one, I'm wondering what size pulley should I buy for my 2K1 auto-max.

Cheers

i think there is only one size
