UR Pulley Just Installed

[EUR003act]

Dyno tested UR pulleys.... Extra 2Kws @ the wheels

15% is over-rated.... Especially if the car is N/A too....

yay! lol way to ruin my night

I'm sorry... Please try and go to bed now

where your engine belt goes around the alternator, power steering, air con compressor, etc... using lighter pulleys and different sizes (smaller crank, air con, steering) means that more power 15% goes direct to the wheels...

No, it's not 15%. The effect is like a flywheel. Almost no significant gain. Maybe 1-2kW just from the reduction of resistance.

lol aaronng, you dont have to rub it in

jokes, and yes bed sounds good right now

You need Gates belt part number K070683. It is slightly shorter than OEM, which is what you want to be used with the UR pulleys. Get it changed ASAP because the OEM belt will suffer accelerated wear as it is too loose. You can confirm it with the accessory belt tensioner indicator. Yours would be pointing at the shorter indicator now. You can get the belt locally at Bursons or Repco.

Edit: fixed typo in part number.

Thanks aaronng for the part number. I'll head out now and go and get it. Much appreciated.

To answer a few questions posted. I think all up from TSXParts I paid $440AUS including shipping. Extra for the installed, think it took my local shop about an hour.

I got the Unorthodox Racing Ultra SS so that included the crank pulley, power steering pulley and accessories pulley. On the dyno as a few have already said the kw's increase was very minimal, but what these pulley's did was increase the accerelation and I definitely noticed it straight away especially through the mid range. I have also found that the power steering feels much, much better when driving - more responsive but a little heavier parking.

So to sum up my thought, if you are after massive gains in kw's at the wheels the pulley's will not do that ... but if you want better accerelation and steering well improved steering I would definitely recommend it.

Thanks everyone for the feedback

I'm in two minds to do this mod.I've had mixed reports eg.James from JTUNE says no(among others),then people like docker(and others on this forum)say how good they are!!

tony1234, I must admit before doing this mod I researched it by reading every post about pulleys in this forum and also the US TSX forums as I was in two minds also. The majority of posts I read was positive towards this mod, the only negatives were if you have an upgraded stereo system in the car you'd need to change the battery to an Optima or something equalivent.

In the end I am glad I have done it because the accerelation gain is very noticable and I feel it replace that low to mid end torque some lose when putting on an CAI.

Hmm.i've got 1x4ch amp(50WRMS/ch.)driving speakers and 1x120WRMS amp driving a 10''sub.wonder if i'd have any problems re:battery longivity??BTW thanks for your feedback.

when running both amps at high volume, the current draw on your battery and consequently your alternater increases, if you alternater is running at a reduced level (which the pulley set will do) it will not be able to supply enough power to outweigh the power drain of the amplifiers... solution, higher capacity battery, or large capaciter... either option (or both) will help sort out the problem. the euro battery is too small for a good stereo install anyway, so it wouldnt harm you upgrading it.

my recommendation, if you want the pulleys, just dont run the amps on full for the last 5minutes of driving, that way the battery has a chance to charge so when you turn the engine off, you can start it again

Makes sense.I might try a Supercharge Gold ,$90,they seem good value.

Just when you thought it was over tony1234...another mod lol.

GO FOR IT TONY1234, hehe
