Back to the flywheel... I understand that removing rotating mass will have an increase in performance...but can you explain what you have seen "real life"?
Are you able to accelerate that much faster or just rev faster? How does it effect your driving on hills or in the mountains?

I thought that there were pros and cons to the lightweight flywheel.

Can you enlighten me?

Thanks
Steve in Waco

I've seen nothing but pros.

Lance has a great review here - http://www.yoursciontc.com/forums/index.php?showtopic=5961

Thanks- On my list of "Do's"

Getting a light weight fly wheel is a good choice. The only con i can see with a light weight fly wheel is you'll slow down faster when off the gas because of the mass inertia is reduced on the flywheel. But I think that's a minimal price to pay to go fast.

one person says no, another says yes, i have the pulley but am so confused, if i should put it or not, what a dilema

maybe i will put it on and c if i notice a difference, if not i will take it off and sell it, problem solved

Steve Dinan says no. Dinan builds the most powerful BMW's outside of Formula 1. I think that means a lot more than anything I say.

Again, let me just say, I've gained a lot of knowledge from reading what you write lo_bux. You've gained the respect of one who usually writes off most people. My hat is off to you for trying to inform the scion community, on numerous occasions, often repeating yourself until nausia.

man, thats just gonna go to his head now.

Has anybody seen this new Crank Pulley?

I am thinking about getting it.

Start here. Then click here. Then click here for information directly from Toyota, the guys who designed your car and engine.

Shawn Baumgartner (owner of Unorthodox Racing) will NEVER tell you there is any danger to his product. I have argued with him in the past about this, he is an idiot. He also will not pay for your engine repairs, he only warrants his crank pulley for manufacturing defects. He does NOT warrant any incidental or consequential damages, and has not paid any claims for damage attributed to his product because his warranty is very specific.

Ask Guillermo Polo, Michael Gaari, Lance at Toyomoto in Miami, and a host of other Supra owners what happens when you remove your harmonic damper and replace it with a UR pulley. Flexplate bolts back out. Crank position wheels break and rotate so the engine either won't start at all, or will fail intermittently while driving. Rod and main bearings show unusual wear patterns. And a host of other wonderful things.

I realize you don't understand the physics. Here's what I can tell you for sure: your oil pump is chain driven. Chains do not like shock loads. Removing the damper increases the shock loading on both the oil pump chain and the cam chain. One (or both) will break prematurely. If they were belt driven, it would be no issue, but they are not belt driven, so they will likely be the first casualties from removing the damper.

The flywheel change has NO negative effects. Zip. Zero. Nada. Nil. It will not void your warranty, but I guarantee you, the UR pulley will because Toyota will show up in court with the same documentation I've linked here and you'll be screwed. It is a BAD mod, and should not be recommended by any reputable engine builder. NO domestic engine builder would ever recommend removing a torsional damper and replacing it with a solid pulley. They know all too well what will happen to a cast crank without a damper: it will break, without any doubt. This is why Fluidamper, ATI, and TCI have a booming business with domestic engines. It is not only bad physics, but it is also bad business to replace a damper with a solid pulley.

now, how are you going to ask our opinions in the same thread we already gave them in? the mfg doesnt change much from one to the other.

I thought it was only for that one pulley.

 

[SpeeedTc]

yeah lance seams to know everything. makes me feel so stupid because of my lack of knowledge compared to him haha.

Add 29 years to your age and see what happens. I could easily be your daddy.

Would you let me borrow the Supra?

Don't do it. Ask Steve Dinan or Reg Riemer why not, they're both very well known tuners (know way more than I do). Wait for ATI, Fluidamper, or TCI to develop a proper torsional vibration damper. Removing the OEM piece could have very detrimental consequences especially since we have a chain driven oil pump.

have they made these yet?

 

[lo bux racer]

Not that I know about. Check with ATI, Fluidamper, and TCI, or better yet, be the first on your block and tell them you'll order 50 to distribute if they make them for you. Sell 49 and get yours free.

My friend got the one from ZPI. I have not told him what it can do to his car yet.
