ZPI Lightweight Crank Pulley

and yet Toyota feels confident enough to let us run 7PSI and warranty it.

oh, i'm sorry. I didn't realize the tc came STOCK with the supercharger. Its not like the s/c release was delayed for approximately a year while they worked out the kinks. And its not like the blower is so overpriced that their profit margin is enough that they can afford to replace any motors that may blow due to the s/c.

And i guess all the boosted Camry's you seen driving around are proof that the 2AZ can handle boost and modding...

Dude, this motor hasn't been battle tested nearly enough in terms of handling boost over extended periods and reliability. I DOUBT Toyota/scion feels "SAFE" putting s/c's out there knowing that people are going to be trying to squeeze as much boost out of it as possible. Thats what a WARRANTY is for!!

2ndly, the pics in this thread came from a TURBO 2az WITH a crank pulley. Totally different. I KNOW toyota doesn't feel "Safe" about tc's with that setup. But then again, Toyota doesn't care. They know that people are going to be VOIDING the warranty with cheap parts like the ZPI pulley. More $$$ for them!

My 3.5 gpa all thru high school and college and my two degrees are the best evidence of my ignorance.

Well anyways, I don't want to support the notion that the tC is the end-all performance monster of "true" sports compacts but before you condemn the tC and all other non-performance engines to being thorough bred hard core daily drivers, just keep in mind that the 2AZ is a pretty stout engine. Toyota made the 2AZ to last. But I'm with you, whether the 2AZ is built to last high or even just low to moderate performance is very much so in question.

Pretty sure that kink was the California Air Resource Board. [/b]

Not really, the TRD S/C is exempt from CARB...

Ignorance
From Wikipedia, the free encyclopedia
Jump to: navigation, search

Ignorance1) is a lack of knowledge. Ignorance is also a "state of being ignorant" or unaware/uninformed. Ex: "In debate class Bill lost the debate because he was ignorant in (without knowledge of) that subject." Ignorance can also be more than a lack of knowledge. It can include a deliberate intent to ignore knowledge or facts that conflict with what someone believes or wants to be true.

(pejorative definition) Ignorance2) is the choice to not act or behave in accordance with what is popular/acceptable in order to suit ones own needs/beliefs."I know better but I choose to ignore that and do/say/act in a way that behooves me."

You Ignorant if you think the 2AZ is meant to handle boost.

Still don't know the reason for your last post. i KNOW what happened to the motor. i DON'T have time to sit here and read every stupid post ("I'm not sure if there were any hoops....mostly just buckets for TRD to fill with money.") every moron puts up here. First off, i'm on dial-up, so that would take 2 years. 2nd, i have much more important things to tend to...like Myspace.

"...like Myspace."

oh god... dont even get me started.

yeah.. bring on the 14 year olds

I asked [email protected] his thoughts on this:

NSTonAIM: the theories that have been derived on the topic have stemmed from those of serious race car drivers and teams

NSTonAIM: teams that build and prep small displacement engines, very high output, and very high redlines

NSTonAIM: 2.5 liter, 500hp, 12,000 rpm

NSTonAIM: those engines also spend 90% of their lives at redline or very close to it

NSTonAIM: in such an application any type of vibration is bad

NSTonAIM: inside, outside, block, head, left, right.... very bad

NSTonAIM: so they are right, the small amount of rubber in the crank pulley does help with that a little bit in such crazy conditions

NSTonAIM: this technology was then carried on over to production cars to help such cars last longer when not taken very good care of by their owners

NSTonAIM: owners who neglect their engines, never change oil, do not do proper maintentance, do not change timing belts on time, do not change gaskets, dont know when they should shift or how they should drive

NSTonAIM: aka soccer moms ;-)

NSTonAIM: now....

NSTonAIM: lets compare your daily driver to that of a race car

NSTonAIM: your 2.4 liter make 500 hp or go to 12,000 rpm???

NSTonAIM: no

NSTonAIM: and lets assume that you drive for 60 minutes in one day

NSTonAIM: how many of those 60 minutes will be spent at redline?

NSTonAIM: waiting for your answer sir

NSTonAIM: how many minutes in one day do you drive at redline?

Me: under 1

NSTonAIM: or better yet, for every 60 minutes that you spend driving, how many minutes are at redline?

NSTonAIM: 1 minute?

Me: it can't be long. seconds at most.

NSTonAIM: ok

NSTonAIM: lets make those other guys arguments even stronger

NSTonAIM: lets assume that for every 60 minutes you spend 10 minutes at redline!!!

NSTonAIM: 10 divided by 60 = what?

Me: a job for calc.exe
Me: 0.166666666666666666666667

NSTonAIM: good

NSTonAIM: so you want to keep comparing your motor to that of a race car?

NSTonAIM: you make 250hp, and go to about 7,000 rpm about 15% of your engines life

NSTonAIM: they make 500hp and to to about 12,000 rpm about 90% of their engines life

NSTonAIM: shall we continue?
Me: I'm surprised you don't post replies to all those people who don't get it

NSTonAIM: well, id like to keep going anyway!!!

Me: haha

NSTonAIM: have you taken a look at our sponsored cars?

NSTonAIM: http://www.nonstoptuning.com/pageSponsoredCars.htm

NSTonAIM: these are full race cars

NSTonAIM: one is SC, the other is turbo

NSTonAIM: they spend 100% of their lives on drift tracks

NSTonAIM: we do nothing but race these to death

NSTonAIM: and over the past few years we have had ZERO issues with our pulleys on these cars

NSTonAIM: would we really take these cars to race tracks and blow them up with our pulleys and make us look like morons?

NSTonAIM: would that be smart business?

Me: haha I suppose not

NSTonAIM: to go one step further....

NSTonAIM: i have not had even one customer contact me during the past few years to say that his motor blew with a pulley of mine

NSTonAIM: not one

NSTonAIM: or as a result of one of our pulleys

NSTonAIM: sure, if you run 15psi through your tC and dont manage it properly itll blow up, with or without a pulley

NSTonAIM: and yes, the theories about vibrations being bad are correct and applicable

NSTonAIM: but not in the case of your car

Next, 99.9% of engines out are NOT MADE FOR BOOST. You think honda designed the civic to have a big ass turbo slapped on it? Of course the engine is being pushed. All engines that are modified beyond thier design points are.

And you talk like you are the expert in the room full of idiots. You so far have shown nothing in the realm of real technical knowledge. A good number of us in here have had our hands under the hood for longer than many others have been old enough to drive. No one is saying the car is a sports car, can handle x amount of boost, etc.. we are simply discussing a very specific set of issues on an engine and devices which are more harmful than good.

Thanks Guru. Certain motors HANDLE and are designed to handle boost better than others.

Was the CIVIC designed to have a big turbo? Thats pretty stupid. NO!

However B series and motors like the H22 are high compression JDM race spec motors, that yes, are designed with boosted applications in mind. You're comparing apples and oranges. The Toyota camry 4 cylinder to a performance B series honda motor!

You'll notice, most people don't boost D series, because, yes that is correct, they don't handle boost as well!

I can hold my own under the hood. I don't have to "Show" my technical knowledge (and how do you SHOW your "technical knowledge" online anyway???) to you or anyone else...

Basically anything that significantly boosts hp in the tc does more harm than good.
