ok well i haven't seen a thread on this option in a while, whould like to get peeps pov on this upgrade these days? what companys sell good ones? where you see the powergains? if any? what motors you like them on?

 

Personally i hate these things, had one on my cavalier like 6 years ago, and it sucked, had one on my old 94 hatch and it made the power dim constantly... i wouldn't recommend it. if your worried about the power gain then just cut your ac and power steering out, the car was made with

 

Underdrive pulleys are only good for cosmetics

They reduce the alternators ability to charge the battery

They make teh power steering pump work harder

They make teh AC compressor work much harder to pressurize the system


READ:> WORTHLESS UNLESS YOU THINK 0.5 - 1.0 horsepower is BOSS

 

The only one i ever run, if i run one is the crank pulley, it's about the only one worth doing imo

 

any other feedback on these things?

 

Are you guys talking about an aftermarket(/unorthidox) crankshaft pulley, should i run it on a d16 with no ac and no power steering. The guy that gave it to me said it would be alright with a racing clutch. But idk? how to install it because an OEM pulley has 3 lines/marks and the aftermarket one has 2. But i assume you'd put it to TDC then just retard the timing from the dizzy.

 

wrong

distributor effects ignition timing

crank pulley effects cam to piston timing, just like an adjustable cam gear

dont bother with an underdrive pulley unless you NEED a new crank pulley and you want more bling

just dont rev it high, they SAY their pulleys are balanced from the factory (unorthodox) but Ive seen some across threads not measuring out very well. Ive seen one on a race car simply from teh start making noise it was so unbalanced. Others, have spun them to 11k rpm and had zero problems for several years


You wanan risk it, go ahead.


For cosmetics, stock crank pulley can easily be cleaned up!

 

well i'm puting a new waterpump/timing belt/alt belt ect. already and I have the unorthidox cranksaft pulley and it's on a d15b block w/ a si tranny and im putting a 94 vtec head d16y8 and it has stage 2 clutch and an aftermarket fuel rail and runnin no ac/ps so i think it could take it. And it does have a race radiator for mini mi high comp.

 

WOW

It must have been quite troublesome to find a 1994 d16y8

Ive never heard of one. Must be one of those black market type of things.

/sarcasm

race radiator? WTF the stock radiator for 92-00 civics works GREAT for even 400whp turbo builds

Someone is trying to sound COOL over the internet

 

Why....why would you spend money on a fuel rail for a mini me?

 

 

wow I didnt catch the fuel rail

Musty be for the triple amount of fuel going for the 25:1 compression!!

 

i have one on my d15b7 but its only because the motor had a broken one when i got it. i havent really noticed any problems so far but also havent noticed any gains either so im pretty neutral on the subject.

 

25:1 compression yikes! might have too get a stronger starter. and possibly 150 octane gas. what kinda power would that get?

 

Just shy of 4500

v12's got nothing on this bitch

 

lulz at this thread!!!!

 

4500 hundred hp! i want one. might need to run some really wide tires to get traction. like some 16x24s.

 

ME TOO

 

underdrive pulleys are for track cars. I can't imagine any logical reason to get one for a driver. The only benefit I've ever known for these is they have extra timing marks on them. But not really worth all the problems they come with. You will likely burn through your alt faster, and your accessories will dim.

 

I've been using it since my B swap and never had problem with it for 2 years now. Don't know the difference since it was there since the beginning.

 

I've run them on plenty on daily drivers with no ill effects, and i've been doing it for years!! Hell, even with an example of something like an oem CTR pulley, nobody i know has ever had an issue with them either.

 

i have one on my b16 and have no problems, it was missing the crank pully so i just got a url alluminum deal

 

do you have accesories like ac, ps, stereo system etc?
They are designed for cars with no accessories.

 

Boy I just love these aggressive expert opinions. The comeradery in the wording "wrong"

A crank pulley does not effect timing whatsoever, although it is marked to measure timing.

Knock off pulley brands that have come and gone over the years do not have balanced pulleys. UR is the only brand that has and always will be perfectly balanced, 0 grams right off the CNC's. You get what you pay for and some are too easily lured by a cheap price only to spend 10-20 times as much to repair the daamge caused by an inferior part.

An underdrive pulley must be designed to maintain accessory output, since none of these cheap knock-offs have an R&D nor engineering staff they never test the diameters to make sure they maintain the required voltage/cooling/power steering pressure. UR is the only one again. You get what you pay for plus a 5 year warranty to back it up.

So risk what? Buying cheap and paying severely later. Pulleys are not apples to apples which is why we continue to be here 15+ years and the other stuff comes and goes as their reputation kills them due to problems.

When every extra horespower or fraction of a horsepower counts pulleys are an easy cost effectie way to free up HP wasted by the stock boat anchor heavy pulleys.

If you don't want to use the product becasue you are afraid don't use it but don't scare others with unfounded, unsubstantiated urban myths.

^^ i think this guy works for unorthidox
