ZPI Lightweight Crank Pulley

Yeah, he would probably not believe it. I e-mailed Fluidampr to see if they have developed a light weight crank pulley. This is want they said.
Michael, thanks for your interest in Fluidampr. Sorry we have not developed one and currently, we do not have one in the works.

Here is a antoher light crank pulley, for who ever wants one. I have been trying to find one like Lo Bux described.

It's actually 12whp and 12 torque, not .5.. it was dynoed on scionlife a few weeks ago, the dynos were done 15 minutes apart from each other.
I have yet to see any problems on any 2AZ-FE yet, some have had it on over 20,000 miles. ZPI is running one on their tC that has ran low 12s several times (talk about some stress on that crank pulley), they haven't had any problems at all with it.
But didnt ZPI just blow up their FM car at the shootout? Bearing failure?

It's ZERO hp and ZERO torque. Sorry, a Dynojet doesn't measure hp or torque, it infers hp and torque from the vehicle's ability to accelerate a known mass. Want more Dynojet hp? Put on lighter wheels and tires. Did you make more power? NO. Does Dynojet think you did? Of course, it is a fundamentally flawed method of measuring hp. You would not measure any increase on a hydraulic or eddy current dyno because the amount of power the engine produces DOES NOT CHANGE ONE WATT. The time it takes to get to top speed is reduced, but top speed remains exactly the same, and top speed is a direct measure of hp.
Low 12's is not stress on the crank pully. Any piece of aluminum can do that. Operating at the crank's resonant frequency for a few hours is stress.

I would have to register. I have no desire to join any more forums. I have no desire to get in another flame war with people who refuse to accept fundamental physics. The engineers who built the engine put a damper on the crank for a reason. They clearly explain why in their training manuals. Steve Dinan also clearly explains why it is foolish to remove a factory damper and replace it with a solid pully.
I've said all I want to say about this more times than I can remember. ZPI does not warranty your engine. They warranty their part. If your engine fails because their part fails to damp crank vibration, guess who foots the bill? You do. Toyota will not warranty it, and neither will ZPI, since they warranty their pulley to be free of manufacturing (NOT DESIGN) defects. That's all you need to understand to get the real deal on what happens next.
As I've said before in this thread, when Fluidamper, ATI, or TCI make a lightweight damper (as they have for Supras), then buy it, run it, and be happy. Until then, all the solid pulleys are junk unless you have the money to buy new engines on a regular basis.

I know that you will not even listen to an argument about this, so I won't waste my time.. You've already made up your mind and there is no changing that.. Some people are just very close minded.
In years from now I could show you 10 engines that have gone 100,000 miles with this crank pulley and you would still not change your mind at all..
About your "I have more experience therefore I know more then you attitude"..I understand that you've been working on engines for 25 years but engines are alot different now adays then they were 25 years ago. So all of that experience doesn't really impress or help me at all, unless of course I had a 25 year old car..
Example: I know DOS very well, but now that windows XP is around knowing DOS isn't very helpful.
Look at all the different huge companies that make light weight crank pulleys.. If these pullies were so bad for the car they would not sell them. I'm not talking about ZPI, other companies like AEM. Do a search on google sometime and look at how many positive things there are about light weight crank pullies. I must of went through 10 pages before I found 1 negative comment (with no evidence to back it up).

They aren't words on wisdom, just my opinion..
I don't think pulley's are as bad as lo_bux says, so I decided to say something. The engine is internally balanced so there should not be any problems. There may be a little more stress on the engine with this pulley but it's not enough to hurt anything. Even your SC puts more stress on the engine, it doesn't mean it's going to hurt it.
Try to show me the tC that has been damaged by this pulley, you will not find any. Everyone who has it installed loves it. Some for over 15,000 miles with zero problems and no regrets.
Please don't tell me you really think that the crank pulley is what caused engine problems on the ZIP tC with stock internals that has ran 14PSI several times..
I think I'll put my money on the turbo.
Wrong, it was called "Dyno Dynamics", it was not a dynojet.
The numbers are valid, you just hate the pulley so much you assumed it was dynojet. In that thread I see it actually gives you 12whp and 18 torque.. The gains are almost completely through the powerband, not just at peak HP.
Look at the dyno sheet for yourself, the dynos were done 15-20 minutes apart from each other on the same dyno, same EXACT mods & conditions, just 1 difference THE PULLEY:
Well since we're all being closeminded, I'm not going to bring up the same arguments.
What I will say is that the ZPI run that blew the car was done at low boost for tuning purposes. Low boost and tuning... I'm assuming ZPI is smart enough to start safe and tune it to where it's making as much power as possible as safely as possible. In that case, how do you suppose the engine broke? It's been shown that high boost in the tC doesn't explode the engine so much as crack a few things. Well, not really high boost but upwards of 15 psi.
So I don't think it's the extremely high boost that blew the engine but hmm... what can cause catastrophic failure... It happened to my dad who forgot to refill the oil in our old Oldsmobile. Wait! no oil? HMMMMMM... no oil, exploded engine... crank pulley, oil chain, no oil, exploded engine... HMMMMMM.
You're right, it's probably the turbo.

DoubleJ16 - how about we put a turbonator, a magnetic fuel enhancer, and Slick 50 in your car and dyno it. If it makes more power then we call them all good fixes.
Are YOU so close minded that you refuse to examine the physics?
Christ, my own grandmother connects herself to electrodes everyday in the foolish belief she is purging her body of bad cells by applying a current at their natural frequency. It doesn't kill her, and she feels better so it must be good eh?
Closed minded about pulleys. Bullsh1t. I'm not closed minded about anything that works. I am violently opposed to snake oil solutions that endanger an engine's service life. You have not seen what I have seen. You very obviously haven't been around engines all your life, or you wouldn't repeat the same COMPLETELY IDIOTIC STATEMENT THAT THE ENGINES ARE INTERNALLY BALANCED.
The OEM pulley doesn't balance a DAMNED thing. The aftermarket pulley doesn't balance a DAMNED thing, and I'VE NEVER SAID IT DID OR DIDN'T BALANCE ANYTHING. You are proving yourself to be outside the realm of ignorant and rapidly joining the ranks of the stupid because you don't read what I wrote, you don't read what Steve Dinan wrote, you don't read what Reg Reimer wrote, and you don't read what Toyota wrote. The only other possibility is you read those things and don't comprehend it.
I'm really sorry you don't get it, and I'm really sorry you think 15,000 miles is a lot of testing. It's not. 100,000 miles is NOT a lot of testing. You have no idea what goes into certifying an engine for production, and it's obvious to me you don't care. Great. Enjoy fixing your ish when it dies prematurely. I know it will, and everybody with a 2JZ that thought I was harsh on Shawn Baumgartner when he tried selling his undampened pulleys on the MkIV list has come back and said, oh, you were right.

If you run it at the resonant frequency for potentially even a few minutes, you could find out exactly what breaks first.
Cranks resonate and break, valve springs resonate and break, cylinder walls resonate and crack. You just have to find the right frequency and it's all like a Memorex commercial.
