replacing crank pulley with asp will eventually trash your crankshaft/engine. There is no harmonic stabilizer in the asp pulley. The stock one has it though.

Do other pulleys have a harmonic stabilizer?

[240dreamer]

unorthadox pulleys don't have one, search for this subject. it's been discussed many times. good luck!

[SilviaS14KA24DE]

yeah our cars don't need the harmonic balancer. search 2BN search

[N.O. Accorderz]

i have searched....my conclusion, it does NOT have a harmonic balancer....but it does have a harmonic dampener for when the a/c clutch kicks in...it just softens the "jolt"...on my other car is the same way...

[SilviaS14KA24DE]

yes, the actual underdrive pulley is acts as the dampener.

[DammitBobby]

Ok does somebody using the pulley have any problems? I want to install this pulley to. This gives me a reason to fix my front main seal leak.

[corn322]

no problems so far. been driving it since last friday.

[SilviaS14KA24DE]

me too, i've had it for two months. still going greaaat

[Dattebayo]

you are full of crap. I dont put my 2 cents into a thread untill i know there is something good to come of it...

The loss to your engine happens over a long grueling time.

Our engines have a VERY long stroke and if you replace stock equipment with unbalanced aftermarket stuff you have only yourself to blame.

You need to have an actual FSM and some knowledge to understand what i speak of. These pulley are not good for your engine and should be avoided.

It is FINE for you to replace every pulley except for your crank pulley. the rest do not matter.

EDIT: by the way, no matter how hard you search, there are threads you cannot reach from the old forums that have these questions answered.

Sorry, but you are wrong.

This debate has been going on for the 4 years since i started reading 240sx.org (our prior board). I'll heard...go 4 it!! from some ppl. And i've heard, no..you'll blow your engine up from others!! I'd balance the crank before i put a pully on, requiring the engine to be taken aprt. I'd try removing the 3-4 lb rubber part of the pully first....it's free. Why bother with a pully when the money is better spent toward a turbo.

[keepingthe240]

An underpully should be a last resort. A decent cam (270*) could make up for the extra power..everyone think 248* is the bomb..get a clue!It's b/s that the highest n/a ka24de on this board is 174rwhp and it was half *** done. I could build up to 190-195 rwhp if i had a 5 speed. Of course a turbo would be cheaper, as everyone will say. But most of the 190-195hp setup could be used with a turbo set up ( excluding pistons,header and intake) and maybe we can break into the 500hp daily driver. I have heard of a 700-800 hp ka24 (drag car) on this board a few yrs ago, though.

[Dattebayo]

no no; no no no. no 500hp daily driver from a KA. Maybe 200 n/a and 350 turbo. Thats all she wrote, but dont ask me.

Look into the "Turbo KA" section for that answer...

If you really want to know what a harmonic dampener does, do a Google search. I don't feel like typing out the physics of crankshafts, but, I can tell you the dampener is there and it has nothing to with the A/C. It is actually built into the front-most pulley on the crank pulley, which is the one that drives the water pump and PS pump. You can remove it by taking out the three bolts in the center and see it for yourself. I know that some UD pulleys will be made so that the stock dampener can be bolted to the new UD unit, but, the ASP is not. It does have 3 drilled and tapped holes in it, but, the dampener wont fit into the pulley. Anyone that has had one of these pulleys for an extended amount of time care to comment?? Just curious if any problems have been associated with the use of an UD pulley.

The engine that we put into my car had a pully on it already...should I take it off??? Or is it ok to leave it on... now Im all freaked out...

[cory2081]

well, I guess one way to look at it is this.........ASP designed the darn pulley, if the pulley not having a dampener on it causes your crank to fail, and you can prove that the pulley was the cause, I guess you could go after ASP.....lol. I am kind of leary about installing one on my car, I bought one a while back but sold it when I found out that the dampener would not bolt to it. If someone out there that has had one of these pulleys for awhile would speak up, I might feel better about it.

[keepingthe240]

lol. I also bought a pully, never installed it and sold it.

[cory2081]

lol. Well, looks like everyone is scared b/c it doesn't allow you to retain the dampener. Maybe we should e-mail ASP and ask them what the deal is??

[cory2081]

ok, I wrote to ASP.......I'll let you guys know what they say!!

[N.O. Accorderz]

i think unorthodox racing designed the pulley and the asp copied it? i mean UR has a pulley set for the KA also...and it doesn;t have the balancer or the dampener on it...and i'm sure UR put some time to testing their products

[xns]

tell me now! while its still in the shop!

[cory2081]

well, the KA doesnt have a balancer, only a dampener. I don't know why they would feel it necessary to eliminate the dampener. We'll just have to see what they say.
