eddnog, yea man i noticed a difference. especially in throttle response, or at least it feels. LO BUX RACER, where did you get your information? do you have a website address from a credible author?if so send me the link please. and yes my oil pump still works, and if im supposed to feel vibration, i havent felt it at all.
i just got off the phone with my personal mechanic, ESC racing, www.escracing.com, and he says he has never heard of a lightweight pulley causing any problems of that sort, and even if it did, why would Unorthodox Racing make a faulty pulley? that opens them up to all sorts of lawsuits. my mechanic is going to call unorthodox racing on monday to see what they say, and im sure it will be the same as his.. overall, im still happy with my buy. fidanza flywheel? why would i do that? if im going to do that im going to get a new clutch as well. sorry, my car is still fairly new.
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.
