NST Pulleys + Automatic Transmission
In the main NST Pulley thread, there is a bit of dancing around inquiries about this product coupled with an A/T.
Given that it is currently a 335 post thread and having just suffered through a search to find information, I thought a new thread specific to automatic owners be started. Initially no modding was being planned for 2009, but if these pulleys on an A/T yield similar results to what M/Ts are claiming, I will probably entertain this mod. Might be nice to be a member of the crowd chanting 'NST FTW!'

What are your concerns? I think it's been well established that NST pulleys are high quality and generate a little bit of additional power. Maybe I can answer any further questions that you have.

No concerns really. I'm not concerned about the quality of the product as I, along with many others, suffered through the great pre-hack debate about NST vs OEM.
Like Mike in his pleadings for people to post up their experiences and reviews, I am looking for much the same but specific to installs on automatics.

The gains that you will see are the same as tha M/T only in your Power Range if an M/T doesn't breakit an A/T won't be close to breaking believe I got both tranny's at Home

I have the pulley set on my AT LB. I put so many mods in the span of two weeks that I cannot attribute a specific improvement to any one mod. There was one mod that was not mistakeable in its effect, but it did require a few more dollars than the rest.

The first mod I did on my o7 with AT was the pullies....all 3. When the underdrive crank was introduced that went on. No problems at all.
It would be the butt dyno talking and it says there is a difference. |

As I have stated several times... the principles of weight reduction and underdriving apply the same way, regardless of transmission type. Weight reduction is very noticeable when it is performed in the rotating assembly. The gains are there, and they are real. We have a large number of automatic owners buying these pulleys.... sadly, as much as I beg and bump and plead, people don't seem to want to post up...
Consider this analogy... Person A weighs 300lbs and goes on a diet, sheds 10% of his weight. Will he notice a difference? Person B weighs 250lbs and goes on a diet, sheds 10% of his weight. Will he notice a difference? The answer should be yes, they will both notice the benefits of weight reduction, even though they started out at different weights. For those who don't consider pulleys a "worthwhile" modification... I find it interesting that many of the same people invest in lighter wheels, body panels, and especially lightweight flywheels. The concept is the same. In fact, weight reduction in the rotating assembly yields better gains than similar weight reduction performed elsewhere. Good luck and have fun with all your projects everyone! |

i went to a clutch/flywheel setup that was 5lbs lighter than stock (would have been more but i went to a stage3 clutch and that pressureplate was HEAVY) and i really didn't notice any power gains. revs dropped off faster (had to re-learn heel-toe downshifting) but the car really didn't feel any more powerful. that's one of the reasons i never did lightweight pullies, cost vs hp it just didn't add up for my very very cheap budget. either way y'all make quality parts, and that's what matters!

trust me just get them, i have a AT sedan, i put the 10% underdrive pulley on first and tested it out for a couple weeks and it was such a good increase in throttle response and so much better. and then i had the water pump and alternator pulley installed and wow, power i felt a little difference but to me with this car is a big difference. I suggest it deffinatly

But back on topic, from what I understand, even the lightweight pulley on an AT leads to the transmission feeling much more lively. It won't be as noticeable a difference as with a MT, but it ought to help make the driving more enjoyable
