wassup people, got my NST 20% Underdrive Crank Pulley this afternoon. the 1st in southern u.s. to have it. this thing sure did make a difference. it gave me better throttle response, and the car picks up a lot faster. im loving it. even my mom can feel the difference. she sat in my car, and she's like what did u do! why is car going so fast.. :silly: lol, i just smiled. it's awesome. its supposed to give you 6-10 hp at the wheels. and the more mods you have the more hp you'll get.

so right now the pulley is still in production. so if you havent pre-ordered your already, DO IT! you'll love it.

i would post some pics, but the pulley is so far back, you cant really see it, but i'll see what i can do.

Hmm, noob question, can this be installed on an AT?

i was thinking the same thing lol
:P and whats the price !??

yup, mines and automatic. check out there website...

http://www.nonstoptuning.com

Dam thats cool i want one . where do u get somthing like that installed?.. and if you could explain how it works OO and does it take off warranty? if u know thankz lol

how much was ur install and idid u need a new belt?

well i went to a local place called carboys. they install all kinds of performance stuff. just go to someone you trust on your engine. yes, it would void your warranty if your dealer finds out. but the pulley wont harm your engine. check the website to see how it works.

the guys charged us 60 bucks, and yes you need a new belt.

Im gunna pick one up just hope my dealer wont find out :pray: :pray: :pray:

this will totallly violate any engine warranty you might have
it is replacing the dampner pulley with a lightweight unit

Moved....

BUt do you think the dealer will actually find out? If any thing does happen ? i allready have a cai and trd springs and getting a injen exhaust witch the dealer did not install im screwed on warrantys as it is right.

Are they still pre-order, or what??
And where did you get the new belt, and size and stuff??

when you install a crank pulley, is it true that the ac and power steering will no longer work??

Oldman has some great points and a lot of knowledge about engines and why these kinds of pullies should not be run on your car. The pullies that bolt on to the existing harmonic balancer are fine..ones that remove your harmonic balancer like the NST are not.

Im not saying he is 100% correct but what he's saying makes a lot of sense and its defenitely something to think about .

after reading that i think ill wait. my dad would kill me if somthing breaks and the warranty is void for 6 Hp.

hey Sam_J84... do you notice a loss in power of you A/C?

I couldve sworn their was a sticky about the TRUTH about so called "voiding your warranty"
Please read it.
I'll give you the abridged version, BY LAW, you warranty CANNOT be "voided" due to the intall of a aftermarket part. If something happens to your car and it can be proven that it was a result of the part...THEN they wont fix it under warranty. Even after that, your warranty is still good for the length of it

The kind of problems you face having from the underdrive pulley can easily be proven to cause damage. Killing your bottom end from removing your harmonic balancer is really hard to blame on anything else.

i have had these pulleys on my toyotas for at least 50,000 miles. no problems thus far of any kind :no:

the a/c and alternator will turn a bit slower at idle, but not so slow to result in any noticable losses. like i said, i have not had any problems of any kind with my motor or accessories as a result.

good mod and amazing dollar to hp ratio if you ask me.

They cant "void" the entire warranty. But if your crank breaks or if your main bearings wear out prematurely and they see that you have removed the balancer/damper you can pretty much count on paying to fix it yourself. Some engines may last longer than others without the damper, but it is there for a reason. I know this is not what anyone wanted to hear after buying the NST, but it is something to think about.

What kind of toyota r u running?

unorthodox racign is coming out with one soon too.

so like a cai and a exhaust would not void anything??

Not unless they can prove it caused the problem.

If you really want to know about UD

http://www.clubsciontc.com/modules.php?name=Forums&file=viewtopic&p=32548#32548

ya it does slow down your alternator but you can barely notice it. the only problem you might have is if your running a high wattage sounds system. like 6000watts or something. dont listen to thses other guys that say your motor will break. they can only talk if they know from experience. The NST guys have used there own pulley's on daily drivers for years without a flaw. that should prove something.
so "engifineer" and "The Instigator" dont talk unless you've used of these pulleys.

and everything will work fine once you install one of these. nothing stops working.

gee the vendor says the UD won't void the warranty. Go figure :clap:
If you read my post an link you will see that the dyno is out 4.5 WHP over 1/3 of the rev range for the FULL set.

do you even have a scion? :loser:

4.5 to the wheel not bad i might think about this again :) On dynos example my cai said 6hp is that to the wheels?

to the wheels, 4.5 WHP is for the full set not just the crank,, so lets say 3 HP and engine warranty is toast for $99.00 and engine life is effected.

so when K&n stated a 6hp gain on the cai it is 6hp to the wheels? yeah u make sense its not worth it!

far harder to show a CAI toasted the engine, scion itself is working on one, exhaust too as TRD has one, now a UD well that is a slam dunk to show that it can damage the engine.

that wasnt my question

I know I was putting in that it is not only a $$ per HP question, out of all the bolt ons the UD is going to be the easiest for the OEM to deny warranty, next would be the header. The CAI, exhaust, flywheel, clutch, I really think the OEM will not take any issue with for the most part and there are TRD versions for, well not the flywheel yet but I bet HKS will have something soon and TRD kind of luvs to follow HKS...

answer my question plz lol when they stated 6 hp does it mean i have 6 hp to the wheels?

In a dyno chart posted by import tuner magazine, a cold air intake on the 2AZ made roughly 4hp at the wheels. That would be roughly 6hp at the crank.

I have had a ud pulley on a turbo 5EFTE and a set on a 4AGE for the past four or five years. These motors have been used for drag racing, daily driving, and weekend track sessions. No buttom end problems thus far.

thank you :)

so "engifineer" and "The Instigator" dont talk unless you've used of these pulleys.

I explicitly stated I wasnt agreeing 100%, just pointing out some very good info from someone who defenitely knows more than you or I about engines and to keep an open mind about what certain mods can and cant do for you. Also beware of what the vendors claim. Remember the tornado that went into the intake that claimed 15hp and better fuel economy? It was total BS.

And by the way I ran underdrive pullies on my 94 Z28 Camaro for years, and had no problems. The only difference was that it bolted on to the existing harmonic balancer unlike the NST pully that removes it altogether which I will not run.

well you dont know what i know. but w/e im not gonna argue with you. im happy with my pulley. and even if it did harm my engine, i would just put the old pulley back on and take it to scion. they wont know the difference. its that simple. all i can say is that the power gains from the pulley are very noticable.

Do some homework on marketing before YOU start talking. Do you think NST is going to say "This will reduce your engine life"? The makers of the turbonator say you can gain all kinds of hp with their peice of junk and we know that is not the case, so you should know you cant believe everything you hear on the internet. If you do, you will be getting ripped off a lot.

NST knows what will happen if it reduces your engine life. A new car (especially a Toyota) should EASILY pass 100 or even 150 thousand miles in life. This long life makes it difficult to say when a part caused it to fail early. So, if it reduces engine life to say 80,000 miles, they are going to tell you "Anything could have done that, poor maintenance, racing the car (after all, you do have performance parts on it), defective engine (but.. oh no, the warranty is out on it anyway) etc..." So there is NO WAY you will get NST to pay. So they are safe either way since the damage done by an improperly balanced engine can take a long time to rear its head. Have I used one of these pulleys? No... Have I rebuilt multiple engines and do I have a very good understanding of what it takes to keep one running? YES. What we are trying to tell everyone is that the balancer is there for a reason. Removing it WILL reduce engine life to some extent. How long?? that all depends on a million other things. It may last 100,000 miles, it may only last 80,000 miles.

well you dont know what i know. but w/e im not gonna argue with you. im happy with my pulley. and even if it did harm my engine, i would just put the old pulley back on and take it to scion. they wont know the difference. its that simple. all i can say is that the power gains from the pulley are very noticable.

And people like you are why the dealers give people such a hard time with warranty work. An ethics course would do you some good. I suppose you also are all for insurance fraud?

would it void the warrenty? i just got my Scion tC 2 weeks ago, and i'm loving it.

They likelyhood is very high that it will cause damage to the engine, if this did occur and they see your pulley, the warranty is gone. The risk is not worth the gain,other parts such as exhaust intake should not be problematic with dealers. Listen to oldman and engifineer they know what they are talking about. And SAM you go ahead and be a bigger man and try to deal with your frustration, Ethics and behavioral complex problems ok.. :doh:

imo, this is an aftermarket part for "tuner junkies". look elsewhere for the gain. really, this is one part the dealer will fight you on. not like cai, springs, etc.,;they will make a stink about this if something goes wrong. jmo, take it for what it is worth.

"some people cant stand people who are better than them"

That is quite the contradictory statement you just made.

Why are you taking our posts like attacks. Were telling you that the part can damage your car. We are not telling you to take it off...just to be aware of all the facts the vendors may not want you to know. If you want to run it go ahead and do it..you may not have any problems, but others should be made aware of the problems they may face using that product. In my eyes, the power gains are minimal in relation to the risk of engine problems down the road.

The bottom line is that harmonic balancers are a necessity to keep an engine running preoperly. If not why would every car on the market have one. I would be willing to bet that any good engine builder would not reccomend you run any engine without a balancer.

I wish you the best in your quest for power but also be willing to admit that you dont know everything and that it would be wise to listen to others who have experience in things you dont know about. Thats why these boards are here...to share information we can all benefit from. Being stubborn and confrontational doesnt help you or anybody else here.

Actually you were the one to start telling others the very same thing, which prompted my response.

If I was questioning you directly with my previous posts, I would have picked on alot more from what you said above.

the only way the dealer will find out is if you they see it. but if something did happen to your engine, all you would have to do is put your old pulley back on, and they wont know the difference.

Still not worth it IMO...best of luck to you though.

or you could spend money on a mod that doesn't take a large chance of destroying your engine and still gives you power LOL

there are many ways to make power without taking chances like that.

what about running an under drive pulley with a supercharger? would the supercharger make less boost? would you need the 9 psi pulley to compensate?

the underdriven pulley is a bad idea for SC. i fyou wanna get a lighter crank pully with the SC get the stock sized pulley. CR-LITE i believe its on special order, unless they got some instock.
