Unorthodox pulley update

[Camry_rider]

For anyone thats been thinking about getting one, heres my summary on the pulley.
Faster revs: Yes.
Gain in top speed : not sure yet, but 90-105 was better
Faster all around : not really sure, but it does feel stronger.

At a little over 1000k miles on the pulley im sure the ecu has been put up to speed, heres what I've noticed.
From a dead stop to floored the car jumps and pulls hard through out the entire rpm range, 2nd gear is about the same as before, 3rd gear feels more power, 4th gear, better pick up, o/d feels better through the 90 mph bog down, pulls harder than before.
Today in neutral I revved up, did my little hello rev to a friend since my horn sounds like it belongs on a short bus, and I over reved the car, I ussually get around 5500,5800. Today when I did it, I hit into the red, and it happened fast. The engine revs easy, it drops revs faster. I think its a good buy.

I give the

Um, 1,000,000 miles? That's one retarded ECU...

is your gen 3 camry I4 or V6?


if V6, is the stock pulley solid metal or is it rubber dampened?

They don't make pulleys for the V6. Only the I4.


Give me a report after 40k miles on it and tell me if your engine is still running

1k miles, sorry. If the car makes it another 40k miles on the engine ill be impressed. Right now im on 160k. Whats so bad about these pulleys that make people cringe?

There have been horror stories about how the pulley will make the engine become unbalance. When the manufacturer put on the pulley with a specific weight, there is a reason for it. When the engine crankshaft is unbalance, the bearings can become loose and cause the whole crank to wobble.

There are some people who have success with pulleys, others not so lucky.


I would only put pulleys on engines that are naturally balanced or that has a balancer somewhere else. Some companies put their harmonic balancer on the oil pump, others such as honda put their balancer on the crank pulley (which is why honda people are more prone to damage if not done right because the rubber balancer is taken out.)

People have told many stories, but I've never seen any hard evidence. I could understand if it was a harmonic balancer being replaced, but these motors are balanced internally so I wouldn't worry. If it was really that bad, I have a hard time believing that Unorthodox would exist anymore. If every engine with an underdrive pulley crapped out, they'd have a hard time selling their product, not to mention dealing with all the lawsuits that would result.

I'm at 207k miles, another 40k is no problem.


Personally, if I was going hardcore, I would do the pulleys despite the possible break down. Rebuilding and engine would be needed yearly anyways on a hardcore race engine. So you wouldn't have anything to worry about. However myself like everyone else has heard the stories. And I just don't think it is worth the risk (at least right now). But good luck with them Zack. Maybe you will prove the stories wrong

Balanced won't remove harmonic. Then the engine is never 100% balanced. The pistons never load the crank balanced. The crank always vibrates.
Without a harmonic balancer the engine will wear out faster question is how much faster.

If your engine is properly and completely balanced you will never have problems resulting from the underdrive pulley.

End of discussion.

Update again guys. My comp crashed, been gone for a while. I put about another 1k on the pulley, its holding its own great. The car is quicker with out a doubt, its pulling hard. I have noticed one minor issue, the steering kinda feels clicky, when I say clicky I mean like when its turned while driving I can feel notches......im not sure what it is just yet. But no real problems at all. I intend on putting the pulley myth to rest, my car is taken to redline more than it sits at idle.....if anyone should blow up from a pulley it should be me. Miami trip coming this friday, ill repost and update again after the trip.

[WhiteRabbit]

good to hear, looking forward to more updates

[mobes]

Good deal.
The notchy steering could be your rack and pinion on its way out. I had that happen to me on my last car. It got progressively worse to the point it wasn't safe to drive, and I had to replace the rack and pinion.

Well, over the weekend I put over 1,000 miles on the car, 600 of which was highway and nothing under 85 mph. The car is more responsive, the top end still sucks ass. *95 mph +*
No real problems yet. I am noticing more engine noise from the engine bay when the car is in idle with the a/c on. Im also hearing a sound similar to bad cv axels, and after all that money....im still leaking fucking oil! I think I pin pointed the steering problem......on the return trip from Miami I was doing about 90-98 mph when I could hear the tires starting to peel apart, I had about 90 miles to go to my house so I kicked it down to 45 mph and set the cruise control, im pretty sure its my tires that are screwing with me. I had one problem today how ever that could be linked to the pulley, but I doubt it. I was working today, had my lowbeams, high beams, radio, a/c kicking, and rear tv on all at once. I shut the car off and the battery was dead. That is the ONLY problem so far and its not even a problem. The engine is doing great with the pulley after about 3k miles.
